Which student loans to pay off first: Stafford or private?
At the current rates, stated in the question, I would push additional funds towards your Stafford loans as their higher interest rates will incur interest charges almost 3 times faster than your private loans. With my loans I have not seen much information regarding private loans jumping the interest rate close to the 6.8% any time in the coming years (if others have insight to this I look forward to the comments).  Due to the private loans being variable there is an element of risk to their rates increasing. Another way to look at it may be to prorate your amount of extra payments according to their interest rate.  $1,000 x 0.068 /(0.068 + 0.025) = $731.18 Toward your Stafford Loans $1,000 x 0.025 /(0.068 + 0.025) = $268.82 Toward your Private Loans Without knowledge of the special provisions of your loan contract, the one with the highest interest rate should be paid first. Or, if one's fixed payment is much larger than the other, and it is a burden, then it should be paid first, but refinancing may be an option. Socially speaking and possibly even economically since it could affect your reputation, it is probably best to either refinance the cosigned loan or pay that off as rapidly as possible. Economically speaking, I would recommend no prepayment since the asset that is leveraged is your mind which will last many decades, probably exceeding the term of the loan, but some caveats must be handled first: Many would disagree, but I finance the way I play poker: tight-aggressive.
Pay off your highest-interest debt first: credit card, car, maybe even mortgage. Pay minimums on all else. Student loans are typically low interest, so pay off anything else first, but double-check your rate of course.  Even if you have no other debt, you may still want to hang on to your savings instead of paying down your student loans if getting rid of your savings causes you to accrue debt. For example, if you have a low income and no savings, you may accrue credit card debt (high interest). Or you may want to buy a car with cash instead of getting a loan. Even if this is not an issue, consider what you can do with your savings that others who lack them cannot do. You can put it into mutual funds, which may offer higher rate of return (albeit with risk) than your student loan interest. Or you may pay a down payment on a home. The very low interest rates of student loans are, to a person with savings, essentially a source of cheap money that doesn't need to be justified to a bank. You can use it as seed money to start a business, as funds for travel, for living expenses while in the Peace Corps, or whatever else. But if you pay down that principal, you bind yourself. In short, pay down your student loans when there is no better use for the money. I work for a private equity firm and recently graduated with a Master's of Finance from a top 20 B School. With that being said, I would not recommend the Master's as a path to PE or CF. You would be better suited to invest in a MBA from a target school. IB is very tough to get into with a MFin depending on the part/product of the bank you are targeting. Happy to answer more specific questions. As someone with a lot of student loan debt, I can relate - the first thing you should do is read the promissory note on your current loans - there might be information there you can use.  For govt loans (stafford, etc) made after July 1, 2006 the interest rate is going to be fixed and even a federal direct consolidation is not going to lower the rates themselves.  If anything, consolidation will just increase the repayment period, which means you'll end up paying more in the long run.   Most private Loans usually offer variable interest rates, which today are quite low. But unless your financial situation is very comfortable and stable, consolidating out of federally guaranteed loans into private loans might not be the best path.  You might lose options like deferment, forbearance, and maybe even things like a death benefit (if you die, your loans die with you). related - if you have a co-signer you don't get that death benefit! But refinancing into a variable rate private loan is going to push a lot of risk to you in terms of interest rate inflation, etc. Most financial professionals will agree that interest rates can only go up in the long run. Keep in mind, student loans are completely unsecured - meaning lenders are taking a fairly large risk in loaning money (and probably why the fed govt has to guarantee most of them).  I've heard of people borrowing against their home equity to pay down student loan debt - but I can't think of a reason you'd want to substitute secured for unsecured debt and possibly lose the loan interest tax deduction.  The bottom line is you're unlikely to find an alternative lending source at a lower interest rate for an unsecured student loan.  Another option may be the income based repayment plan. If you qualify, it caps student loan monthly payments at 15% of your discretionary income (discretionary is your income minus whatever the poverty threshold income amount is). And if that 15% doesn't even cover the interest on the loans, the govt picks up the tab for the difference (for up to 3 years). You have to re-qualify every year by sending in all sorts of documentation, but if you somehow stay on IBR for 25 years, your loans are then forgiven. Obviously the downside here is that you are probably paying little to no principal, but if you do the math and determine that your IBR payment would be next to nothing, and your current situation is barely paying interest-only... well, maybe IBR isn't a bad thing for a couple of years (or 25 if you think you will never have a larger income).   Personally, I went through all these options as well and decided that my best option was to just earn more money... a 2nd job or side project here and there helps me pay down the debt faster, and with less risk, than moving to private variable rate loans. If you're not worried about making the car loan payments, why would you want to pay off a loan that is not charging you any interest? Pay off the interest bearing student loan. I agree with the advice given, but I'll add another angle from which to look at it. It sounds like you are already viewing the money used to either pay off the loan early or invest in the market as an investment, which is great. You are wise to think about opportunity cost, but like others pointed out, you are overlooking the risk factor. The way I would look at this is: I could take a guaranteed 6.4% return by paying off the loan or a possible 7% return by investing the money.  If the risk pays off modestly, all you've done is earned 0.6%, with a huge debt still hanging over you. Personally, I would take the guaranteed 6.4% return by paying off the debt, then invest in the stock market. Now this is looking at the investment as a single, atomic pool of money.  But you can split it up a bit.  Let's say the amount of extra disposable income you want to invest with is $1,000/mo.  Then you could pay an extra $500/mo to your student loan and invest the other $500 in  the stock market, or do a 400/600 split, or whatever suits your risk tolerance. You mentioned multiple loans and 6.4% is the highest loan.  What I would do, based on what I value personally, is put every extra penny into paying off the 6.4% loan because that is high.  Once that is done, if the next loan is 4% of less, then split my income between paying extra to it and investing in the market. Remember, with each loan you pay off, the monthly income that previously went to it is now available, and can be used for the next loan or the other goals. "Which option will save you the most money in the long run? That is tough. Assuming you stay healthy, don't lose your job, don't experience a pay cut or any major emergency that drains your savings, then applying the $6000 to the higher interest loan will save you more money in the long run. However, the difference in savings is a few hundred dollars. Not much really. So, in this case, I'd put the $6k towards the smaller loan. Why? Because then you'd pay it off faster. Once that's done, you open up your cash flow by the minimum monthly payment you would have had on that loan.  Assuming they both have the same or similar number of months left, by paying the smaller loan off sooner, you'd open up $X month, where $X is your minimum monthly payment. This could be useful to you if you want to take on some other debt (like buying a house) because it lowers your debt to income ratio. If you put that money towards the higher loan, your DTI won't change until the normal time you would have paid off the smaller loan. Even if you are not looking to purchase anything that requires you to have a lower DTI, paying the smaller loan off sooner increases your cash flow sooner (because your monthly payment on the higher loan doesn't change just because you lowered the balance by $6k). So you'd be more robust to emergencies if your current income doesn't allow for much savings. A major emergency could wipe out all savings from paying down the bigger balance. So, I'd suggest: Edit: TripeHound asked a question, pretty much requesting more details for why I was biased towards paying off the smaller loan first. What follows is my response, with a bit of reorganization: Typically, people asking these questions don't have so much wealth that ""which loan to pay first?"" is an academic question. They need to make smart financial decisions. While paying the highest interest loan saves the most money in interest - that only occurs under the assumption that nothing bad will ever happen to you until the loans are paid off. In reality, other things happen. Tires blow out, children get sick, you get laid off and so the ""best"" thing to do is the one that maximizes your long term financial health, even if it comes at the expense of a few $k more interest. Each loan has a minimum monthly payment. Let's assume, barring any windfalls of additional cash, you will just make the minimum payments each month towards a loan. If you pay off the smaller loan first, that increases your available monthly cash flow. At that point, you can put extra towards the other loan. However, if an emergency should come up, or you need to save for a vacation, you can do that, without negatively impacting the second loan, because you'd just drop back to its minimum payment. Putting the money towards the higher balance loan would mean it takes you longer to reach this point as the time to reach payoff on the first loan will not change ($6k only reduces the $25.6k loan to $19.6k) so you never gain the flexibility of additional cash flow until the time you would have paid off the $13.5k originally. I'd rather have a few hundred dollars each month that I can choose to use to make additional loan payments, eat out, pay for car repairs, pay for emergencies than be forced to dip into credit or worse, pay day loans, should an emergency happen." I would not advise this for two reasons: Your point that the investment could be lower at the end of the 3 years is a concern, although with a safe investment, it is less so, but this reduces the potential gain. While your interest is not gaining interest, your interest charged is based on the principal. If you pay off the loans, you reduce the principal and therefore you pay less interest in the long run, even if the interest isn't capitalized. All that this means is that you are basically being charged simple interest as opposed to compounding interest, but reducing the principal helps in either case. You are mistaken about the benefits of the tax deduction. You reduce your tax bill by the marginal rate times the student loan interest you paid for the year. So if you are in the 15% tax bracket and paid $100 in interest, you save $15. This is not a reason to keep the loans (because you have to pay $100 to get $15), but you are mistaken on the benefit, it has nothing to do with shifting the tax brackets. Also, speaking of taxes, don't forget that you pay taxes on investment gains. "Is a student loan a type of loan or just a generic name used to refer to a loan for someone who is going back to school? A student loan from the federal government is a specific type of loan used for education purposes (i.e. attending college). They have guidelines associated with them that are very flexible as compared to a student loan from a private bank.  If a student loan is a different type of loan, does it only cover the costs of going to the school? Every student at a university has a ""budget"" or the ""cost of attendance"". That includes direct and indirect costs. Direct costs are ones billed directly to you (i.e. tuition, room and board - should you choose to live on campus, and associated fees). Indirect costs are such things like books, travel expenses (if you live out of state), and personal things. Direct costs are controlled by the school. Indirect costs are estimated. The school will usually conduct market research to determine the costs for indirect items. Some students go above that, and some go below. For example, transportation is an indirect cost. A school could set that at $500. There are students who will be above that, and some below that. If you choose not to live on campus, then rent and food will become an indirect cost. Student loans can cover up to 100% of your budget (direct and indirect added together). If your total budget is $60,000 (tuition, room and board, transportation, books, supplies, etc.) Then you are able to borrow up to that amount ($60,000). However, because your budget is both direct and indirect costs, you will only be billed for your direct costs (tuition, etc.). So if your direct costs equal $50,000 and your student loan was certified for $60,000, then you will get that $10,000 back in the form of a refund from the school. That does not mean you don't have to pay it back - you still do. But that money is meant for indirect costs (i.e. books, rent - if you're not staying on campus, etc.). If your school is on semesters vs quarters, then that amount is divided between the terms. Summer term is not factored in, that's another process. Also with student loans, there are origination costs - the money associated with processing a loan.  A good rule of thumb is to never borrow more than you need.  Source: I used to work in financial aid at my college." "If I had to guess (since you provided little information about your loan repayment), I'd guess that you're on the ""Extended"" repayment plan for your $72k loan, and the ""Standard"" plan for your $30k loan. In general, there are 4 main kinds of student loan repayment plans This holds true for federal loans (Direct/Stafford/PLUS). Private loans may not have all of these options, or they may have more. Running your numbers, I get 300 payments of $500/mo at 6.8% interest for a $72,000 loan, and 120 payments of $345/mo at 6.8% interest for a $30,000 loan. Now, to address your issue of interest vs principal, you should notice that each month you pay, the interest payment is slightly lower, and the principal slightly higher. And if you make bi-weekly payments, you'll see that change a LITTLE bit more quickly (slightly smaller balance accruing interest for 14 days of the month) and you'll also pay slightly less over time." First, read my answer here: Oversimplify it for me: the correct order of investing For me, the answer to your question comes down to how badly you want to get rid of your student loan debt. I recommend that you get rid of it as fast as possible, and that you sacrifice a little in your budget temporarily to make that happen. If that is what you want, here is what I would do. Following the steps in my other answer, I would pay off the student loans first. Cash out your non-retirement growth fund to jump start that, then challenge yourself to take as much of your paycheck as you can and throw it at the debt. Figure out how many months it will take before the debt is gone.  Once the debt is gone, you won't have those monthly payments anymore and you won't be continually losing money in interest to the bank. At that point, you can build up your cash savings, invest in your employer's 401(k) plan for retirement, and start saving toward other long-term saving goals (car, house, etc.) To address some of your other concerns: If you cash out the non-retirement fund, you'll probably owe some capital gains tax. (Although, on a $3k investment, the long term rate won't add up to very much, depending on your tax bracket and cost basis.) You can't use the money from your non-retirement fund to invest in your 401(k).  You can only contribute to your 401(k) via payroll deduction.  To explicitly answer your question, your non-retirement fund is not bound by the limitations of retirement funds, meaning that you can cash it out and use it however you like without penalty, only paying perhaps a few hundred dollars of capital gains tax at tax time next year. Think of it as another source of cash for you. So one approach would be purely mathematical: look at whichever has the higher interest rate and pay it first. Another approach is to ignore the math (since the interest savings difference between a mortgage and student loan is likely small anyways) and think about what your goals are.  Do you like having a student loan payment?  Would you prefer to get rid of it as quickly as possible?  How would it feel to cut the balance in HALF in one shot? If it were me, I would pay the student loan as fast as possible. Student loans are not cancellable or bankruptable, and once you get it paid off you can put that payment amount toward your house to get it paid off. First, let me fill in the gaps on your situation, based on the numbers you've given so far. I estimate that your student loan balance (principal) is $21,600. With the variable rate loan option that you've presented, the maximum interest rate you could be charged would be 11.5%, which would bring your monthly payment up to that $382 number you gave in the comments. Your thoughts are correct about the advantage to paying this loan off sooner.  If you are planning on paying off this loan sooner, the interest rate on the variable rate loan has less opportunity to climb. One thing to be cautious of with the comparison, though: The $1200 difference between the two options is only valid if your rate does not increase.  If the rate does increase, of course, the difference would be less, or it could even go the other way.  So keep in mind that the $1200 savings is only a theoretical maximum; you won't actually see that much savings with the variable rate option. Before making a decision, you need to find out more about the terms of this variable rate loan: How often can your rate go up? What is the loan rate based on? I'm not as familiar with student loan variable rate loans, but there are other variable rate loans I am familiar with: With a typical adjustable rate home mortgage, the rate is locked for a certain number of years (perhaps 5 years).  After that, the bank might be allowed to raise the rate once every period of months (perhaps once every year).  There will be a limit to how much the rate can rise on each increase (perhaps 1.0%), and there will be a maximum rate that could be charged over the life of the loan (perhaps 12%). The interest rate on your mortgage can adjust up, inside of those parameters.  (The actual formula used to adjust will be found in the fine print of your mortgage contract.)  However, the bank knows that if they let your rate get too high above the current market rates, you will refinance to a different bank.  So the mortgage is typically structured so that it will raise your rate somewhat, but it won't usually get too far above the market rate.  If you knew ahead of time that you would have the house paid off in 5 years, or that you would be selling the house before the 5 years is over, you could confidently take the adjustable rate mortgage. Credit cards, on the other hand, also typically have variable rates.  These rates can change every month, but they are usually calculated on some formula determined ahead of time.  For example, on my credit card, the interest rate is the published Prime Rate plus 13.65%.  On my last statement, it said the rate was 17.15%.  (Of course, because I pay my balance in full each month, I don't pay any interest.  The rate could go up to 50%, for all I care.) As I said, I don't know what determines the rate on your variable rate student loan option, and I don't know what the limits are.  If it climbs up to 11.5%, that is obviously ridiculously high.  I recommend that you try to pay off this student loan as soon as you possibly can; however, if you are not planning on paying off this student loan early, you need to try to determine how likely the rate is to climb if you want to pick the variable rate option. My recommendation would be to pay off your student loan debt as soon as possible. You mention that the difference between your student loan and the historical, long-term return on the stock market is one-half percent.  The problem is, the 7% return that you are counting on from the stock market is not guaranteed.  You might get 7% over the next few years, but you also might do much worse.  The 6.4% interest that you will save by aggressively paying off your debt is guaranteed. You are concerned about the opportunity cost of paying your debt early.  However, this cost is only temporary.  By drawing out your debt payments, you have a long-term opportunity cost.  By this, I mean that 4 years from now, you could still have 6 years of debt payments hanging over your head, or you could be debt free with all of your income available to save, spend, or invest as you see fit. In my opinion, prolonging debt just to try to come out 0.5% ahead is not worth the hassle or risk. Two different questions: Is it better to be in debt or to pay off the debt? And: Is it better to have student debt than other debt?  Any debt needs to be paid off eventually, and any debt makes you less flexible. So if you have the choice between spending/wasting your money and paying off debt, I would recommend paying off the debt.  The other question is whether having student debt is better than having other debt. You need to look at the terms of your student debt. Pay off the debt with the worst conditions first. Loan sharks (in Britain: pay-day loans) must be paid first. Credit cards debt must go next. Then general loans. Depending on your situation, you may want some savings as well. In case you lose your job, for example. So if you have $8,000 saved and an $8,000 student loan, you might consider waiting a bit before you pay back the loan. No job + $8,000 student loan + $8,000 in the bank is better than no job + no debt + no money in the bank. Like all other loan-vs-savings questions, it depends on the terms of the loan. If you have a choice, the usual answer is to pay off the loan with the worst terms (which usually means the highest interest rate) first, and only start with savings when you've paid off all the high-interest loans entirely. If your student loan is on US terms, then pay it off as soon as you can, unless you have commercial debt (credit-card or unsecured personal loan), which you should pay off first, or unless you have or are realistically likely to get eligibility for a forgiveness program. But it does depends on the terms of the debt, which in turn depend on the country you studied in; on UK terms it's a very bad idea to pay off a student loan any faster than you have to.  Interest is restricted to the rate of inflation, so good investments probably beat the interest rate of the student loan; the required repayments vary with your income, so savings are more useful than debt repayment if you encounter income difficulties (e.g unemployment) in the future, and finally the debt is automatically forgiven after 30 years, so you may never have to pay it all back anyway - so why pay it off voluntarily if it would get forgiven eventually anyway?
