Should I always pay my credit at the last day possible to maximize my savings interest?
If you have the ability to pay online with a guaranteed date for the transaction, go for it. My bank will let me pay a bill on the exact date i choose. When using the mail, of course, this introduces a level of risk.  I asked about rates as the US currently has a near zero short term rate. At 3.6%, $10,000, this is $30/month or $1/day you save by delaying. Not huge, but better in your pocket than the bank's. "To avoid nitpicks, i state up front that this answer is applicable to the US; Europeans, Asians, Canadians, etc may well have quite different systems and rules. You have nothing to worry about if you pay off your credit-card statement  in full on the day it is due in timely fashion. On the other hand, if you routinely carry a balance from month to month or have taken out cash advances, then making whatever payment you want to make that month ASAP will save you more in finance charges than you could ever earn on the money in your savings account. But, if you pay off each month's balance in full, then read the fine print about when the payment is due very carefully: it might say that payments received before 5 pm will be posted the same day, or it might say before 3 pm, or before 7 pm EST, or noon PST, etc etc etc. As JoeTaxpayer says, if you can pay on-line with a guaranteed day for the transaction (and you do it before any deadline imposed by the credit-card company), you are fine.  My bank allows me to write ""electronic"" checks on its website, but a paper check is mailed to the credit-card company. The bank claims that if I specify the due date, they will mail the check enough in advance that the credit-card company will get it by the due date, but do you really trust the USPS to deliver your check by noon, or whatever? Besides the bank will put a hold on that money the day that check is cut. (I haven't bothered to check if the money being held still earns interest or not).  In any case, the bank disclaims all responsibility for the after-effects (late payment fees, finance charges on all purchases, etc) if that paper check is not received on time and so your credit-card account goes to ""late payment"" status.  Oh, and my bank also wants a monthly fee for its BillPay service (any number  of such ""electronic"" checks allowed each month). The BillPay service does include payment electronically to local merchants and utilities that have accounts at the bank and have signed up to receive payments electronically. All my credit-card companies allow me to use their website to authorize them to collect the payment that I specify from my bank account(s). I can choose the day, the amount, and which of my bank accounts they will collect the money from, but I must do this every month. Very conveniently, they show a calendar for choosing the date with the due date marked prominently, and as mhoran_psprep's comment points out, the payment can be scheduled well in advance of the date that the payment will actually be made, that is, I don't need to worry about being without Internet access because of travel and thus being unable to login to the credit-card website to make the payment on  the date it is due. I can also sign up for AutoPay which takes afixed amount/minimum payment due/payment in full (whatever I choose)  on the date due, and this will happen month after month after month  with no further action necessary on my part.  With either choice,  it is up to the card company to collect money from my account on the day specified, and if they mess up, they cannot charge late payment fees or finance charge on new purchases etc.  Also, unlike  my bank, there are no fees for this service. It is also worth noting that many people do not like the idea of the credit-card company withdrawing money from their bank account, and so this option is not to everyone's taste." Mostly ditto to Dillip Sarwate. Let me just add: I don't know how you're making your payments, whether through the biller's web site, your bank's web site, by mail, in person, etc. But whatever the mechanism, if there is a chance that waiting until the due date to pay may mean that you will miss the due date: don't. The cost of a late payment charge is likely to far exceed any interest you would collect on your savings. Bear in mind that we are talking pennies here. I don't know how much the monthly bills that we are discussing here come to. Say it's $3,000. I think that would be a lot for most people. You say you're getting 3.6% on your savings. So if, on the average, you pay a bill 2 weeks later than you might have, you're getting an extra 2 / 52 x 3.6% x $3,000 in interest, or $4 per month. I think the last time I paid a late fee on a credit card it was $35, so if you make one mistake every 8 months and end up getting a late fee it will outweigh any savings.  Personally, I pay most of my bills through either my bank's web site or the biller's web site. I schedule all payments when I get a paycheck, and I generally try to schedule them for 1 week before the due date, so there's plenty of breathing room.
I'm not asking if I should carry a balance to the end of the billing period and accrue interest Typically (I say typically because there may be some fringe outlier exception product that begins accruing interest immediately), if you're not carrying a balance already you will not be charged interest for carrying a balance during the billing period.   You accrue a balance, you're issued a statement, if you pay the statement before the due date indicated you don't pay interest; even if your statement balance is less than the current actual balance on the account.  If you carry a balance through that due date you begin to accrue interest.  Not only on the balance carried but on all new charges as well.  But as long as you consistently pay your statement balance before the statement due date you will not be charged any interest. As for a reason why you may want to take advantage of this, simply to ease the administration of your finances.  You just don't need to touch the accounts that frequently to avoid interest charges.  Sure you can let your money sit in an interest bearing account and earn a couple dollars a year but really, you just don't need to focus on your CC charges this frequently. Credit cards are meant to be used so generally it doesn't hurt your credit score to use them.  To top it off you even get an interest grace period so you don't have to rush home and pay balances as soon as they're charged.   In general you accrue charges during your statement period, we'll call it September 1 through September 30.  The statement due date is something like 20 days after the close of the statement period, so we'll call it October 20.  As long as you habitually pay your entire statement balance by the due date you will never pay interest.  You charge your laptop on September 3, it shows up on your statement as $1,300, you pay $1,300 on October 18, you pay no interest. However, if you pay $1,000 on October 18 leaving a $300 balance to be carried in to the next statement period (a carried balance) you will pay interest.  Generally interest is calculated based on your average daily balance during the statement period, which is now be the October 1 to October 31 period.  You'll notice that you didn't pay anything until the October 18, that means the entire $1,300 will be included in your average daily balance up to the 18th of the month.  Add to that, anything else you charge on the card now will be included in your average daily balance for interest charge calculation purposes. The moral of the story is, use your card, and pay your entire statement balance before the due date.   Now how much will this impact your credit score?  It's tough to say.  Utilization is not a bad thing until it's a big number.  I've read that 70% utilization and over is really the point at which lenders will raise an eyebrow and under 30% is considered excellent. If you have one card and $1,300 is a significant portion of your available limit, then yes you should probably pay it down quickly.  Spend six or so months using the card and paying it, then call your bank and ask for a credit line increase. "I think so.  I am doing this with our furniture.  It doesn't cost me any more money to pay right now than it will to pay over the course of 3 years, and I can earn interest on the money I didn't spend. But know this: they aren't offering 0%, they are deferring interest for 3 years.  If you pay it off before then great, if you don't you will owe all the accumulated interest. The key with these is that you always pay it, and on time.  Miss a payment and you get hosed.  If you don't pay on time you will owe the interest that is being deferred.  They will also be financing this through a third party (like a major bank) and that company is now ""doing business with you"" which means in the US they can call you and solicit new services.  I am willing to deal with those trade offs though, plus, as you say, you can always pay it off. WHY THEY DO IT (what is in it for them...) A friend of mine works for a major bank that often finances these deals here is how they work. Basically, banks do this to generate leads for their divisions that do cold calls.  If you are a high credit, high income customer you go to a classic bank and request cash, if you are building credit or have bad credit, you go to a ""financial services"" branch.  If you tend to finance things like cars and furniture, you get more cold calls." Much money is made by creditors on the transaction value of a client in addition to interest value.  Knowing that, I pay off all my cards every month, have never made a late payment, and get a number of offers every year for reward type cards. Don't ever be worried about paying off your card in full, just be sure you're using your card and that you pay on time, every time. "a link to this article grabbed my Interest as I was browsing the site for something totally unrelated to finance.  Your question is not silly - I'm not a financial expert, but I've been in your situation several times with Carmax Auto Finance (CAF) in particular. A lot of people probably thought you don't understand how financing works - but your Car Loan set up is EXACTLY how CAF Financing works, which I've used several times. Just some background info to anyone else reading this - unlike most other Simple Interest Car Financing, with CAF, they calculate per-diem based on your principal balance, and recalculate it every time you make a payment, regardless of when your actual due date was.  But here's what makes CAF financing particularly fair - when you do make a payment, your per-diem since your last payment accrued X dollars, and that's your interest portion that is subtracted first from your payment (and obviously per-diem goes down faster the more you pay in a payment), and then EVerything else, including Any extra payments you make - goes to Principal. You do not have to specify that the extra payment(S) are principal only. If your payment amount per month is $500 and you give them 11 payments of $500 - the first $500 will have a small portion go to interest accrued since the last payment - depending on the per-diem that was recalculated, and then EVERYTHING ELSE goes to principal and STILL PUSHES YOUR NEXT DUE DATE (I prefer to break up extra payments as precisely the amount due per month, so that my intention is clear - pay the extra as a payment for the next month, and the one after that, etc, and keep pushing my next due date). That last point of pushing your next due date is the key  - not all car financing companies do that. A lot of them will let you pay to principal yes, but you're still due next month. With CAF, you can have your cake, and eat it too. I worked for them in College - I know their financing system in and out, and I've always financed with them for that very reason.  So, back to the question - should you keep the loan alive, albeit for a small amount. My unprofessional answer is yes! Car loans are very powerful in your credit report because they are installment accounts (same as Mortgages, and other accounts that you pay down to 0 and the loan is closed). Credit cards, are revolving accounts, and don't offer as much bang for your money - unless you are savvy in manipulating your card balances - take it up one month, take it down to 0 the next month, etc. I play those games a lot - but I always find mortgage and auto loans make the best impact.  I do exactly what you do myself - I pay off the car down to about $500 (I actually make several small payments each equal to the agreed upon Monthly payment because their system automatically treats that as a payment for the next month due, and the one after that, etc - on top of paying it all to principal as I mentioned).  DO NOT leave a dollar, as another reader mentioned - they have a ""good will"" threshold, I can't remember how much - probably $50, for which they will consider the account paid off, and close it out. So, if your concern is throwing away free money but you still want the account alive, your ""sweet spot"" where you can be sure the loan is not closed, is probably around $100.  BUT....something else important to consider if you decide to go with that strategy of keeping the account alive (which I recommend). In my case, CAF will adjust down your next payment due, if it's less than the principal left. SO, let's say your regular payment is $400 and you only leave a $100, your next payment due is $100 (and it will go up a few cents each month because of the small per-diem), and that is exactly what CAF will report to the credit bureaus as your monthly obligation - which sucks because now your awesome car payment history looks like you've only been paying $100 every month - so, leave something close to one month's payment (yes, the interest accrued will be higher - but I'm not a penny-pincher when the reward is worth it - if you left $400 for 1.5 years at 10% APR - that equates to about $50 interest for that entire time - well worth it in my books. Sorry for rambling a lot, I suck myself into these debates all the time :)" If the bank wants to close your account, they will do just that. Having a small ongoing balance isn't going to prompt them to keep it open.  Typically, the risk is for a card with zero usage to be closed, as it's a cost to them to keep the account open, and it has no revenue. To avoid this, it's a good idea to use that card or cards for a regular purchase, say, gasoline. A non-impulse buy, and just pay in full to avoid interest. There's no need to keep a balance accruing interest.  Keep in mind - A bill contains a month of charges. The bill for December is issued on the 31st, but due January 25th or so. When you pay it in full you do not have zero balance, you have the charges from January. This accomplishes your goal, will no interest. "Plenty!  Following are just a few: For things like RESP and RRSP which have an ""end"" date; as you or your children age, you should be migrating to less speculative investments and more secure ones.  When children are young, for example, you might be in a ""growth"" type fund.  Later on, you would likely want to switch that to an ""income"" fund, which is also more conservative and less likely to lose principal. Are you getting the best benefit from your credit cards?  Is there another card with benefits that you would get more ""back"" from using?  Is that fee-based Air miles card worth it?  Is cash-back better for you? If you have regular investment withdrawals, can you increase them?  Do you like the plan they are going in to?  Similarly look over any other long-term debt repayment.  Student loans, car loans, mortgage.  What is coming up this year, what is ""ending"".  If, for example, car payment will end, how will you earmark that money, so it just does not disappear into general funds. While you could go over things like these more often, once a year should be plenty often to keep tabs and not obsess. Good Luck!" "Dave Ramsey would tell you to pay the smallest debt off first, regardless of interest rate, to build momentum for your debt snowball.  Doing so also gives you some ""wins"" sooner than later in the goal of becoming debt free." Ditto to Victor. The simple rule is: Pay the minimums on all so you don't get any late fees, etc, then pay off the highest interest rate loan first. A couple of special cases do come to mind: If one or more of these are credit cards, then, here in the U.S. at least, credit cards charge you interest on the average daily balance, unless you pay off the balance entirely, in which case you pay zero interest. So for example say you had two credit cards, both with 1% per month interest, with debt of $2000 and $1000. You have $1500 available. Ignoring minimum payments for the moment, if you put that $1500 against the larger balance, you would still pay interest on the full amount for the current month, or $30. But if you paid off the smaller and put the difference against the larger, then your interest for the current month would be only $15. (Either way, your interest for NEXT month would be the same -- 1% of the $1500 remaining balance or $15 -- assuming you couldn't pay off the other card.)  If one or more of the loans are mortgage loans on which you are paying mortgage insurance, then when you get the balance below a certain point -- usually 80% of the original loan amount -- you no longer have to pay mortgage insurance premiums. Thus the amount you are paying on such premiums needs to be factored into the calculation. There may be other special cases. Those are the ones that I've run into. This is a slightly different reason to any other answer I have seen here about irrationality and how being rationally aware of one's irrationality (in the future or in different circumstances) can lead you to make decisions which on the face of it seem wrong. First of all, why do people sometimes maintain balances on high-interest debt when they have savings? Standard advice on many money-management sites and forums is to withdraw the savings to pay down the debt. However, I think there is a problem with this. Suppose you have $5,000 in a savings account, and a $2,000 credit card balance. You are paying more interest on the credit card than you get from the savings account, and it seems that you should withdraw some money from the savings account, and pay off the cc. However, the difference between the two scenarios, other than the interest you lose by keeping the cc balance, is your motivation for saving. If you have a credit card balance of $2,000, you might be obliged to pay a minimum payment of $100 each month. If you have any extra money, you will be rewarded if you pay more in to the credit card, by seeing the balance go down and understanding that you will soon be free from receiving this awful bill each month. To maintain your savings goal, it's enough to agree with yourself that you won't do any new spending on the cc, or withdraw any savings.  Now suppose that you decide to pay off the cc with the savings. There is now nothing 'forcing' you to save $100 each month. When you get to the end of the month, you have to motivate yourself that you will be adding spare cash to your $3,000 savings balance, rather than that you 'have to' pay down your cc. Yes, if you spend the spare cash instead of saving it, you get something in return for it. But it is possible that spending $140 on small-scale discretionary spending (things you don't need) actually gets you less for your money than paying the credit card company $40 interest and saving $100? You might even be tempted to start spending on your credit card again, knowing that you have a 0 balance, and that you 'can always pay it off out of savings'. It's easy to analogize this to a situation with two types of debt. Suppose that you have a $2,000 debt to your parents with no interest and a $2,000 loan at high interest, and you get a $2,000 windfall. Let's assume that your parents don't need the money in a hurry and aren't hassling you to pay them (otherwise you could consider the guilt or the hassle as a form of emotional interest rate). Might it not be better to pay your parents off? If you do, you are likely to keep paying off your loan out of necessity of making the regular payments. In 20 paychecks (or whatever) you might be debt free. If you pay off your loan, you lose the incentive to save. After 20 months you still owe your parents $2,000. I am not saying that this is always what makes sense. Just that it could make sense. Note that this is an opposite to the 'Debt Snowball' method. That method says that it's better to pay off small debts, because that way you have more free cash flow to pay off the larger debts. The above argues that this is a bad idea, because you might spend the increased cash flow on junk. It would be better to keep around as many things as possible which have minimum payments, because it restricts you to paying things rather than gives you the choice of whether to save or spend. Typically the power of capitalized interest would work in your favor and you could carry the loan paying it down while investing the original sum which would earn interest. BUT you aren't going to get any sort of return to compare with 15% so pay off that loan immediately. Also contrary to popular belief (and reiterated here) paying off incurred balance on your credit card every month is responsible use of credit but it will not do much for your credit score. The score ultimately means your ability to pay your bills and most importantly your willingness to pay interest, i.e. revolving the borrowed money. At least in the consumer market where the product they want you to buy is paying monthly interest charges. It is COMPLETELY no use to pay earlier (during a billing cycle) to better your credit score! Your credit score gets affected ONLY once a month from each creditor, and that happens when they post your monthly statement. Thus, no matter what you do or pay and how many times a month or how many days earlier than your due date, it has NO EFFECT WHATSOEVER on your score. Anything you do will be reflected only after the statement. What you pay in between those two statements is irrelevant. So, as far as credit score goes IT DOESN'T MATTER. However, if you want to save on interest being charged, it is wise to pay as early as possible, so your balance is as low as possible for day-by-day calculation of your interest. "There are other good answers to the general point that the essence of what you're describing exists already, but I'd like to point out a separate flaw in your logic: Why add more complications so that ""should I call this principal or interest"" actually makes a difference? Why's the point (incentive) for this? The incentive is that using excess payments to credit payments due in the future rather than applying it to outstanding principal is more lucrative for the lender. Since it's more lucrative and there's no law against it most (all) lenders use it as the default setting." "Credit Cards typically charge interest on money you borrow from them.  They work in one of two ways. Most cards will not charge you any interest if you pay the balance in full each month.  You typically have around 25 days (the ""grace period"") to pay that off.  If that's the case, then you will use your credit card without any cost to yourself. However, if you do not pay it in full by that point, then you will owe 19.9% interest on the balance, typically from the day you charged the payment (so, retroactively).  You'll also immediately begin owing interest on anything else you charge - typically, even if you do then pay the next month the entire balance on time.  It's typically a ""daily"" rate, which means that the annual rate (APR) is divided into its daily rate (think the APR divided by 365 - though it's a bit different than that, since it's the rate which would be 19.9% annualized when you realize interest is paid on interest).   Say in your case it's 0.05% daily - that means, each day, 0.05% is added to your balance due.  If you charged $1000 on day one and never made a payment (but never had to - ignore penalties here), you'd owe $1199 at the end of the year, paying $199 interest (19.9*1000). Note that your interest is calculated on the daily balance, not on your actual credit limit - if you only charge $100, you'd owe $19.90 interest, not $199. Also note that this simplifies what they're actually doing.  They often use things like ""average daily balance"" calculations and such to work out actual interest charged; they tend to be similar to what I'm describing, but usually favor the bank a bit (or, are simpler to calculate). Finally: some credit cards do not have a grace period.  In the US, most do, but not all; in other countries it may be less common.  Some simply charge you interest from day one. As far as ""Standard Purchases"", that means buying services or goods.  Using your credit card for cash advances (i.e., receiving cash from an ATM), using those checks they mail you, or for cash-like purchases (for example, at a casino), are often under a different scheme; they may have the same rate, or a different rate.  They likely incur interest from the moment cash is produced (no grace period), and they may involve additional fees.  Never use cash advances unless you absolutely cannot avoid it." "The basic optimization rule on distributing windfalls toward debt is to pay off the highest interest rate debt first putting any extra money into that debt while making minimum payments to the other creditors. If the 5k in ""other debt"" is credit card debt it is virtually certain to be the highest interest rate debt. Pay it off immediately. Don't wait for the next statement. Once you are paying on credit cards there is no grace period and the sooner you pay it the less interest you will accrue. Second, keep 10k for emergencies but pretend you don't have it. Keep your spending as close as possible to what it is now. Check the interest rate on the auto loan v student loans. If the auto loan is materially higher pay it off, then pay the remaining 20k toward the student loans. Added this comment about credit with a view towards the OP's future: Something to consider for the longer term is getting your credit situation set up so that should you want to buy a new car or a home a few years down the road you will be paying the lowest possible interest. You can jump start your credit by taking out one or two secured credit cards from one of the banks that will, in a few years, unsecure your account, return your deposit, and leave no trace you ever opened a secured account. That's the route I took with Citi and Wells Fargo. While over spending on credit cards can be tempting, they are, with a solid payment history, the single most important positive attribute on a credit report and impact FICO scores more than other type of credit or debt. So make an absolute practice of only using them for things you would buy anyway and always, always, pay each monthly bill in full. This one thing will make it far easier to find a good rental, buy a car on the best terms, or get a mortgage at good rates. And remember: Credit is not equal to debt. Maximize the former and minimize the latter."
