Should I Pay Off my Student Loan Debts First or Invest in an Index Fund?
You are on the right track with your math, but be wary of your assumptions. If you can borrow money at x% (and can afford to make payments on the debt), and you can get a return of > x% from investing, then you would make more money by keeping the debt and investing your savings. Another way to think of it: by paying off the debt you are getting a guaranteed 5% return because that's the rate you'd have paid if you kept the debt. Be wary of your assumption of getting a 10% return in the S&P 500. Nothing is guaranteed, even over the long term. Actual results may well be less, and you could lose money. It doesn't have to be all-or-nothing: why not pay off the higher rate debt at 5% and keep the 3% debt? That's a guaranteed 5% return by paying off the NSLSC loan. And 3% is a pretty low interest rate. If you can afford to make the payments, I see nothing wrong with investing your savings instead of paying off the loan. Make sure you have an emergency fund, too. "A major thing to consider when deciding whether to invest or pay off debt is cash flow. Specifically, how each choice affects your cash flow, and how your cash flow is affected by various events. Simply enough, your cash flow is the amount of money that passes through your finances during a given period (often a month or a year). Some of this is necessary payments, like staying current on loans, rent, etc., while other parts are not necessary, such as eating out. For example, you currently have $5,500 debt at 3% and another $2,500 at 5%. This means that every month, your cashflow effect of these loans is ($5,500 * 3% / 12) + ($2,500 * 5% / 12) = $24 interest (before any applicable tax effects), plus any required payments toward the principal which you don't state. To have the $8,000 paid off in 30 years, you'd be paying another $33 toward the principal, for a total of about $60 per month before tax effects in your case. If you take the full $7,000 you have available and use it to pay off the debt starting with the higher-interest loan, then your situation changes such that you now: Assuming that the repayment timeline remains the same, the cashflow effect of the above becomes $1,000 * 3% / 12 = $2.50/month interest plus $2.78/month toward the principal, again before tax effects. In one fell swoop, you just reduced your monthly payment from $60 to $5.25. Per year, this means $720 to $63, so on the $7,000 ""invested"" in repayment you get $657 in return every year for a 9.4% annual return on investment. It will take you about 11 years to use only this money to save another $7,000, as opposed to the 30 years original repayment schedule. If the extra payment goes toward knocking time off the existing repayment schedule but keeping the amount paid toward the principal per month the same, you are now paying $33 toward the principal plus $2.50 interest against the $1,000 loan, which means by paying $35.50/month you will be debt free in 30 months: two and a half years, instead of 30 years, an effective 92% reduction in repayment time. You immediately have another about $25/month in your budget, and in two and a half years you will have $60 per month that you wouldn't have if you stuck with the original repayment schedule. If instead the total amount paid remains the same, you are then paying about $57.50/month toward the principal and will be debt free in less than a year and a half. Not too shabby, if you ask me. Also, don't forget that this is a known, guaranteed return in that you know what you would be paying in interest if you didn't do this, and you know what you will be paying in interest if you do this. Even if the interest rate is variable, you can calculate this to a reasonable degree of certainty. The difference between those two is your return on investment. Compare this to the fact that while an investment in the S&P might have similar returns over long periods of time, the stock market is much more volatile in the shorter term (as the past two decades have so eloquently demonstrated). It doesn't do you much good if an investment returns 10% per year over 30 years, if when you need the money it's down 30% because you bought at a local peak and have held the investment for only a year. Also consider if you go back to school, are you going to feel better about a $5.25/month payment or a $60/month payment? (Even if the payments on old debt are deferred while you are studying, you will still have to pay the money, and it will likely be accruing interest in the meantime.) Now, I really don't advocate emptying your savings account entirely the way I did in the example above. Stuff happens all the time, and some stuff that happens costs money. Instead, you should be keeping some of that money easily available in a liquid, non-volatile form (which basically means a savings account without withdrawal penalties or a money market fund, not the stock market). How much depends on your necessary expenses; a buffer of three months' worth of expenses is an often recommended starting point for an emergency fund. The above should however help you evaluate how much to keep, how much to invest and how much to use to pay off loans early, respectively." Pay off the debt first.  Life circumstances change without notice, and starting any stage of life with a debt puts you at a disadvantage.  Luckily, your debt is small.  Please also consider accumulating a 6 month emergency fund before making investments. This will further protect you when life hands you a curveball.
You should plan 1-3 months for an emergency fund.  Saving 6 months of expenses is recommended by many, but you have a lot of goals to accomplish, and youth is impatient.  Early in your life, you have a lot of building (saving) that you need to do. You can find a good car for under $5000.  It might take some effort, and you might not get quite the car you want, but if you save for 5-6 months you should have a decent car.  My son is a college student and bought a sedan earlier this year for about $4000. Onto the house thing.  As you said, at $11,000*2=$22,000 expenses yearly, plus about $10,000 saved, you are making low 30's.  Using a common rule of thumb of 25% for housing, you really cannot afford more than about $600-700/month for housing -- you probably want to wait on that first house for awhile. Down payments really should be about 20%, and depending upon the area of the country, a modest house might be $120,000 or $520,000.  Even on a $120,000, the 20% down payment would be $24,000. As you have student loans ($20,000), you should put together a plan to pay them off, perhaps allocating half your savings amount to paying down the student loans and half to saving? As you are young, you should have strong salary gains in the first few years, and once you are closer to $40,000/year, you might find the numbers working better for housing. My worry is that you are spending $22,000 out of about $32,000 for living expenses.  That you are saving is great, and you are putting aside a good amount.  But, you want to target saving 30-40%, if you can. I think about debt as a good option for capital investments that offer a return. In my opinion, a house and clothes you need for that new job are good things to borrow for. School is ok, depending on the amount. Car is ok, if it's a 3 year loan. The rest is not good. You should try to carry as little debt as possible, but don't let it dominate your life. If faced between the choice of paying ahead on your student loan and blowing $300 on an XBox, you should pay the loan. If the choice is between taking your kid to the zoo and paying the loan, have fun at the zoo. "The question posted was, ""Should I pay off a 0% car loan""? The poster provided a few details: I'm ahead on 0% interest car loan. I don't have to make a payment until October. I currently owe $3,000 and I could pay it all off. Should I do that or leave that money in my savings account that earns 2% interest? The question seems to seek a general rule of thumb for how to behave with smaller debts. And a general rule of thumb could be taken from one of two principles (which seem to be religious camps). The ""free money"" camp believes that you can invest (even small amounts) of money risk-free and receive high returns, tax free, for zero effort. The ""reduce debt"" camp believes that you should pay off debts so that you have the freedom to live your life unfettered. Which religion do you prefer? I tend to prefer paying off debts. The ""free money"" tent wants you to pay the car off over the next 6 months, earning interest. Suppose you can earn 2% interest (.02/12 per month), paying $500 per month for 6 months. So you earn interest on 3000 the first month, 2500, the second month, 2000 the third month, So, are you feeling rich, earning $13.13? How much time did you spending making the 5 additional payments? You could skip coffee once/month and make a bigger difference. The ""reduce debt"" tent would have you pay off the car. Suppose you change your deductible on the car (or drop collision) to save money, and you will also same time by avoid 5 bill payments, But do you still have enough money in your emergency fund, how do you feel about having less insurance coverage, and did you notice the time savings? We really need more information about the poster's situation. The answer should consider the relevant details of the situation to provide an informed response. Here are questions that would enable a response to address the whole situation. Why are these important? Here are a few reasons why the above might be important." "Your questions seek answers to specifics, but I feel that you may need more general help. There are two things, I feel, that you need to learn about in the general category of personal finance.  Your asking questions about investing, but it is not as important, IMHO, as how you manage your day-to-day operations.   For example, you should first learn to budget.  In personal finance often times ""living on a budget"" equates to poor, or low income.   That is hardly the case.  A budget is a plan on how to spend money.  It should be refreshed each and every month and your income should equal your expenses.  You might have in your budget a $1200 trip into the city to see a concert, hardly what a low income person should have in theirs. Secondly you need to be deliberate about debt management.  For some, they feel that having a car payment and having student loans are a necessary part of life and argue that paying them off is foolish as you can earn more from investments.  Others argue for zero debt.  I fall in the later.  Using and carrying a balance on high interest CCs and having high leases or car payments are just dumb.  They are also easy to wander into unless you are deliberate.   Third you need to prepare for emergencies.  Engineers still get laid off and hurt where they are unable to work.  They get sued.  Having the proper insurance and sufficient reserves in the bank help prevent debt. Now you can start looking into investments.   Start off slow and deliberate with investing.  Put some in your company 401K or open some mutual funds on the side.  You can read about them and talk with advisers, for free, at Fidelity and Vanguard.  Read books from the library. Most of all don't get caught up in too much hype.  Things like Forex, options, life insurance, gold/silver, are not investments.  They are tools for sales people to make fat commissions off the ignorant.      You are fortunate in that Engineers are very likely to retire wealthy.  They are part of the second largest demographic of first generation rich.  The first is small business owners.   To start out I would read Millionaire Next Door and Stop Acting Rich.  For a debt free approach to life, check out Financial Peace University (FPU) by Dave Ramsey (video course).  His lesson on insurance is excellent.   I am an engineer, and my wife a project manager we found FPU life changing and regretted not getting on board sooner.  Along these lines we have had some turmoil, recently, that became little more than an inconvenience because we were prepared." "I will add one thought on to this thread.  This is a financial concept called ""Net Present Value"".  In plain English, it means ""What's the best use for your money right now?"" So, let's say you have an extra €300/month which is not being spent on living expenses. If you leave that money under your pillow (or spend it on beer or fancy electronics!) instead of paying off your startersloan early, that is costing you 300*(0.04/12) per month, every month.  So €1/month, or €12/year.  This is cumulative for the life of your loan.  So not paying €300 this month will ultimately cost you €120 assuming you keep the loan open for 10 years.  If you're saying ""pay my debts or spend the money on a snappy smartphone?"" the answer is that you should pay your debts. Now, here's the important part.  Let's suppose you have a better use for the money than beer or electronics.  Let's suppose you have a mutual fund which will reliably provide you with a return of 10% a year. If you put that €300/month into a high-yield fund, and if the returns are consistent, you are STILL paying that €12/year (because you invested elsewhere and didn't pay your debts), but you are realizing profits of 300*(0.1/12)=€2.5/month on the invested money.  €2.5-1=€1.5/month, which is a net gain.  So, in some cases, paying off your debt may not be the best use of your money. There are a number of other questions involved which are related to your exposure to capital gains taxes, incentives or disincentives for holding debt, &c. &c.  These are generally country specific.  A poster above who seems to be familiar with Netherlands law did a good explanation of some of those incentives.  I'm in the US, and our incentive and disincentive system is different. TL;DR:  It depends." At the moment the interest rate... implies a variable rate mortgage.  I believe rates are only going to go up from here. So, if I were in your position, I would pay off the mortgage first.  If you don't have 3-6 months in savings for an emergency, I would invest that much money in low risk investments.  Anything remaining I would invest in a balanced portfolio of mutual funds. The biggest benefit to this is the flexibility it gives you.  Not being burdened by a monthly mortgage frees you up to invest.  This may be in your stock portfolio each month or it may be in your community or charitable causes. You have financial margin. First, I would point you to this question:  Oversimplify it for me: the correct order of investing With the $50k that you have inherited, you have enough money to pay off all your debt ($40k), purchase a functional used car ($5k), and get a great start on an emergency fund with the rest.  There are many who would tell you to wait as long as possible to pay off your student loans and invest the money instead. However, I would pay off the loans right away if I were you. Even if it is low interest right now, it is still a debt that needs to be paid back. Pay it off, and you won't have this debt hanging over your head anymore.  Your grandmother has given you an incredible gift. This money can make you completely debt free and put you on a path for success. However, if you aren't careful, you could end up back in debt quickly. Learn how to make a budget, and commit to never spending money that you don't have again. 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.
