Does anyone offer no interest loans?
Such loans are of course possible. They exist because the lender gains something other than interest from them: What would happen to the economy if these were common? These are common, common as anything. In fact where it's not banks lending the money, these are the default. So, nothing would happen to the economy, this is one of the ways the economy works all over the world. If you're more interested in a loan from a bank or other financial institution, made to you for whatever purpose you want - here's $10,000, have fun, give it back ten years from now - ask yourself what the bank would get from that? Perhaps they could do it as a perk when you do something else with them like get a mortgage or keep $1000 in your chequing account all the time. But in the absence of any other relationship, what would be their reason for taking on the overhead and paperwork of approving you for a loan and keeping track of whether you're paying it back or not, for no return, whether financial or intangible? No return? It doesn't happen. This is very much possible and happens quite a lot. In the US, for example, promotional offers by credit card companies where you pay no interest on the balance for a certain period are a very common thing. The lender gains a new customer on such a loan, and usually earns money from the spending via the merchant fees (specifically for credit cards, at least). The pro is obviously free money. The con is that this is usually for a short period of time (longest I've seen was 15 months) after which if you're not careful, high interest rates will be charged. In some cases, interest will be charged retroactively for the whole period if you don't pay off the balance or miss the minimum payment due.
"Your thinking is unfortunately incorrect; an amortising loan (as opposed to interest only loans) pay down, or amortise, the principal with each payment. This means that the amount that is owed at prepayment will always be less than the total borrowed, and is also why some providers make a charge for prepayment. The ""fairness"" arguments that you make predicated on that misunderstanding are, therefore, incorrect." Lending isn't profitable when interest rates are this low.  Consider what's involved to offer a savings or checking account.  The bank must maintain branches with tellers.  The bank has to pay rent (or buy and pay property taxes and utilities).  The bank has to pay salaries.  The bank has to maintain cash so as to make change.  And pay for insurance against robbery.  All of that costs money.   At 6% interest, a bank can sort of make money.  Not great money, but it takes in more than it has to pay out.  At 4% interest, which is about where ten year mortgage rates are in Canada, the bank doesn't make enough margin.  They are better off selling the loan and closing their branches than offering free checking accounts.   An additional problem is that banks tend to make money from overdraft fees.  But there's been a move to limit overdraft fees, as they target the most economically vulnerable.  So Canadian banks tend to charge monthly fees instead.  UK banks may also start charging monthly fees if interest rates stay low and other fees get curtailed. "A ""true"" 0% loan is a losing proposition for the bank, that's true.  However when you look at actual ""0%"" loans they usually have some catches: There might also be late payment fees, prepayment penalties, and other clauses that make it a good deal on average to the bank.  Individual borrowers might be able to get away with ""free money"", but the bank does not look to make money on each loan, they look to make money on thousands of loans overall. For a retailer (including new car sellers). the actual financing costs will be baked into the sales price.  They will add, say, 10% to the sales price in exchange for an interest-free loan. They can also sell these loans to an investment bank or other entity, but they would be sold at a deep discount, so the difference will be made up in the sales price or other ""fees"". It's possible that they would just chalk it up to promotional discounts or customer acquisition costs, but it would not be a good practice on a large scale." The bank depends on the laws of large numbers.  They don't need to make money on every customer -- just on average. There are several ways that zero interest makes sense to them: You asked about banks, and I don't think you see this last scheme in use very much by a bank.  Here's why.   First, customers absolutely hate it - and when you drop the interest bomb, they will warn their friends away, blow you up on social media, call the TV news consumer protectors, and never, ever, ever do business with you again.  Which defeats your efforts in customer acquisition.  Second, it only works on that narrow range of people who default just a little bit, i.e. who have an auto-pay malfunction.  If someone really defaults, not only will they not pay the punishment interest, they won't pay the principal either!  This only makes sense for secured loans like furniture or cars, where you can repo that stuff - with unsecured loans, you don't really have any power to force them to pay, short of burning their credit.  You can sue them, but you can't get blood from a stone. Zero percent interest may sound great, but those deals often have extra margin built into the price to make up for it. If you see 0%, find it cheaper somewhere else and avoid the cloud over your head. "I read up on it and saw that the IRS can ""charge"" the loan provider on   interest even if the loan provider doesn't charge interest, but this   is normally mitigated by the 0% interest being considered a gift and   as long as it's below X amount your fine. Yes, this sums it up. X is the amount of the gift exemption, the $14K. However, you must differ between loan with no interest and loan with no paying back. With loan with no interest you're still giving a statutory gift of the IRS mandated minimum interest. However, the principal is expected to be repaid to you and you must show that this expectation is reasonably fulfilled. If you cannot (i.e.: you gave a ""loan"" with no intention of it being paid back), then the IRS will recharacterize the whole amount as the gift, and you'll be on the hook for gift tax for the amounts above the exemption. What defines a loan vs a gift in terms of the IRS, is it simply that   the loan will be paid back, or is it only considered a loan if a   promisary note is made? As I said - you must be able to show that the loan is indeed a loan, even if it is with no interest. I.e.: it is being repaid, it is treated as a loan by all parties, and is not an attempt to evade gift tax. Promissory note is not a must, but will definitely be helpful in showing that. But without the de-facto repayment of the loan, it will be hard to argue that it is not a gift, even if you have a promissory note. That means, you should make a loan in such a way that the borrower will (begin) repaying it reasonably soon, so that you can show payment schedule being followed and money moving back to you. Reasonably soon is not of course defined in a statute, so do consult with a EA/CPA licensed in your state on how to structure the loan so that it will not appear as an attempt to evade the gift tax. Are there any limits on how big a loan can be? No, but keep in mind that even with statutory interest charges (published by the IRS monthly, see the link), with large enough loan you can exceed the gift tax exemption. Also, keep in mind that interest is taxable income to you. Even if you gift it back (i.e.: the statutory interest)." I mean, at a personal level, I do this all the time. I will absolutely take advantage of low interest financing offers if I know I can make more money with the outstanding balance than will be drawn in interest.  It can also make sense from a risk management perspective: I need liquidity even if I can cover the cost, I anticipate needing a large sum of cash over a short interval during the finance period. If I were to pay all upfront the cumulative expenditures would Darwin me too close to my safety threshold for my comfort level, but by financing I can distribute the risk and keep a higher margin for error over the course of the loan. "Whether or not the specific card in question is truly 0% interest rate for the first 12 months, such cards do exist. However, the bank does make money out of it on the average: Still, 12 months of not having to think about paying the bill. Nice. This is exactly what they want you to do. Then in 12 months, when you start thinking about it, you may find out that you don't have the cash immediately available and end up paying the (usually very large) interest. It is possible to game this system to keep the ""free"" money in investments for the 12 months, as long as you are very careful to always follow the terms and dates. Because even one mishap can take away the small profits you could get for a 12 month investment of a few thousand dollars, it is rarely worth the effort." "Tell them you will not loan them any more money until their existing debts are paid off. This is closer to how the real world works and it won't come across as vengeful or like your changing your initial ""contract"". If they protest, lovingly tell them that your money is not their money, and that an interest free loan from their father is a privilege, not a right. As far as charging interest on your loans, go for it! Charge them 5% or something small. Just don't do it on the existing loans or that will come across as changing your initial ""contract"" again, and perhaps once they've proven themselves to be reliable borrowers they can once again earn the privilege to have an interest free loan. The book ""The Millionaire Next Door"" has really good thoughts on this in its section on Economic Outpatient Care." Of course, the situation for each student will vary widely so you'll have to dig deep on your own to know what is the best choice for your situation. Now that the disclaimer is out of the way, the best choice would be to use the Unsubsidized Stafford loan to finance graduate school if you need to resort to loans. The major benefits to the Unsubsidized Stafford are the following: You'll be forced to consider other loan types due to the Unsubsidized Stafford loan's established limits on how much you can borrow per year and in aggregate. The borrowing limits are also adjustable down by your institution. The PLUS loan is a fallback loan program designed to be your last resort. The program was created as a way for parents to borrow money for their college attending children when all other forms of financing have been exhausted. As a result you have the following major disadvantages to using the PLUS loan: You do have the bonus of being able to borrow up to 100% of your educational costs without any limits per year or in aggregate. The major benefit of keeping your loans in the Direct Loan program is predictability. Many private student loans are variable interest rate loans which can result in higher payments during the course of the loan. Private loans are also not eligible for government loan forgiveness programs, such as for working in a non-profit for 10 years. Banks worry that the large gift might be a loan that is ultimately expected to be repaid. If so, that affects the cash flow of the recipient, and makes it more difficult to make the mortgage payments to the bank.  In some cases, of course, it is an informal loan: Dad advances a large $X to son to use as a downpayent, but does not charge interest and the expectation is that the money will be returned in smaller chunks as and when the son can afford to repay Dad.   In some cases, Dad truly means it as a gift, but son feels an obligation to repay the money, if not explicitly, then by paying for the first few months of Dad's nursing home stay, etc.  So, banks like to have an explicit document such as a copy of a letter from Dad saying that this money is a gift, and some assurance that this is on the up and up.   If the amount is larger than the maximum gift that can be given each year without having to file a gift tax return, then some assurance that a gift tax return will be filed is helpful. Mentioning this in the letter is good: it indicates that there are no secret handshakes or secret agreements to the effect that this is in fact a loan, with or without regular repayments. I funded about a half dozen loans. All were AA or A rated. All but one paid me. The one who stiffed me wiped out all my profit on the others. I ended up with a tiny negative return. At your age, the only place you are going to get a loan is from relatives. If you can't... Go to next year's conference. Missing it this year might feel like a disaster, but it really, really isn't. In addition to a fee-only advisor, brought up by dg99, you could consider asking your questions on message boards such as Bogleheads.org. I have found the advice amazing, obviously conflict-free, and free. I have abused 0% interest programs time and time again, but only because my wife and I are assiduous about paying our bills on time. We've mostly taken advantage of it with bigger purchases that we've done through Lowe's or Home Depot (eg - washing machines, carpeting, stove, fridge), but its been well worth it.  There are two rules that we set for ourselves whenever we do a 0% interest program -- 1) We have the money already in savings so that we can easily pay it off at any time 2) We agree to pay our monthly bill on time There's nothing quite like using another person's money to buy your things, while keeping your money to gain interest in a savings account.
