How should I utilize my money as I begin grad school?
For some ideas on investing priority guidelines, see Oversimplify it for me: the correct order of investing. Congratulations on being debt free!  My advice to you is to do what you can to remain debt free. You could certainly invest the money; it will earn much more over the long-term in a stock mutual fund than it would left in a savings account.  However, if you need any of this money in the next few years, it would be a shame if it lost money in the short-term. How much do you need to finish grad school?  Don't invest that money in the stock market, because you will need it over the next few years. Likewise, think about other expenses that are coming up.  Will your car need to be replaced in the next couple of years?  Will you have enough income to meet your living expenses while you are in grad school, or will you need some of this to money to help with that?   Finally, it would be good to keep some extra as an emergency fund, so you can easily pay for any unexpected expenses that come up. If you can make it through grad school debt free, you will be much better off than if you invest all the money but take out student loans in the process. After you've accounted for all of that, whatever is left of the money could definitely be invested.  If your goal is to start a retirement fund, an index mutual fund invested inside a Roth IRA is a great place to start.
"Yes, it can be a good idea to close unused credit cards.  I am going to give some reasons why it can be a good idea to close unused accounts, and then I will talk about why it is NOT necessarily a bad idea. Why it can be a good idea to close unused accounts ""I'd like to close the cards.""  That is reason enough.   Simplifying your financial life is a good thing.  Fewer accounts let you focus your energy on the accounts that you actually use. Unused accounts still need to be monitored for fraud. You mentioned that you have high credit card balances that you are carrying.  This may indicate that you have trouble using credit responsibly, and having more credit available to you might be a temptation for you. If these unused cards have annual fees, keeping them open will cost money. Unused cards sometimes get closed by the bank due to inactivity.  As a result, the advice often given is that, in addition to not closing them, you are supposed to charge something to it every month.  This, of course, takes more of your time and energy to worry about, as well as giving you another monthly bill to pay. Why it is NOT necessarily a bad idea to close unused accounts Other answers will tell you that it may hurt your credit score for two reasons: it would increase your utilization and lower your average account age.  Before we talk about the validity of these two points, we need to discuss the importance of the credit score. Depending on what your credit score currently is, these actions may have minimal impact on your life.  If you are in the mid 700's or higher, your score is excellent, and closing these cards will likely not impact anything for you in a significant way. If you aren't that high in your score yet, do you have an immediate need for a high score?  Are you planning on getting more credit cards, or take out any more loans?  I would suggest that, since you have credit card debt, you shouldn't be taking out any new loans until you get that cleaned up.  So your score in the mean time is not very important. Are you currently working on eliminating this credit card debt?  If so, your utilization number will improve, even after you close these accounts, when you get those paid off.  Utilization has only a temporary effect on your score; when your utilization improves, your score improves immediately. Your average account age may or may not improve when you close these accounts, depending on how old they are compared to the accounts you are leaving open.  However, the impact of this might not be as much as you think. I realize that this advice is different from other answers, or other things that you may read online.  But in my own life, I do a lot of things that are supposedly bad for the credit score: I only have two credit cards, ages 2.5 and 1.5 years.  (I closed my other cards when I got these.)  My typical monthly utilization is around 25% on these cards, although I pay off the balance in full each month, never paying interest.  I have no car loan anymore, and my mortgage is only 4 months old.  No other debt.  Despite those ""terrible"" credit practices, my credit score is very high. Conclusion Make your payments on time, get out of debt, and your score will be fine.  Don't keep unwanted accounts open just because someone told you that you should." And this tells me you have little to no understanding. I have LIVED this life, I am black, from an inner city, my father is a deadbeat and my mother was diagnosed with MS, leaving her disabled until she died before I graduated from high school. My grandmother raised me while trying to care for a daughter that couldn't walk and another daughter struck blind by disease. Without public assistance, I wouldn't have been healthy enough to get a scholarship to a very expensive boarding high school, and really isolate myself from the shit around me. i have cousins who died living the gangster bullshit life, I know this world from seeing it. I make a fairly decent amount of money now, why, because when I couldn't find a job, I could still eat on food stamps and go to a free program to qualify for the government to pay for my IT certification. So, seeing as I KNOW how the system can be used to get to a better place, make a goddamn argument that your idea works better, not how you feel things should be. I make me decisions based on what I've seen, I have known women shafted by circumstance struggling to be able to work because they need a specific number of hours to ensure they can have child care so they can work at all. I have tutored adults that never graduated high school because they had to drop out and work years ago to help their families afford to live. I have used medicaid to help with my horrible episodes of depression, gotten treatment my family alone could not afford. I have watched my aunt recover from drug addiction using treatment my family could not afford. My grandmother is alive and still helping the down and out in our family due to medical equipment the family could not afford on its own. I do base my decisions on evidence, I have lived the fucking evidence. Not an HLS-er myself, but that's basically my experience with HLS students/grads as well. There are many HLS grads who are mind-numbingly brilliant and provide a unique contribution to their focus or organization. There are also plenty who kept their head downs for 20 years and kept perfect grades, but who just apply existing techniques to known problems and add no unique value over a cheaper counterpart from a lower-ranked school (other than maybe social connections to other HLS grads). Since you already have established a set of expenses, most importantly your rent. Blair Hodgson DuQuesnay said, “You don’t want to spend more than one-third of your take-home pay on your housing, whether that’s rent or a mortgage. With almost everything else, you can work from there.” She also recommends that your static bills — housing, utilities, and other fixed expenses that recur monthly — don’t take up more than 50% of your budget. If you can keep them even lower than 50%, like, say 40% or 35%, you’ll have even more spending money for everything from food to clothing to savings. So basically, it is time to start to be worried if you are exceeding half of your budget on your expenses. Forbes has an excellent article on how new grads can plan to budget their money. "This sounds exactly like being an assistant professor.  1) Deal with nebulous and arbitrary funding agencies (""One ""good"" rating means you don't get funded!"") 2) Force your grad students to work long hours on very tenuous projects 3) Still might not get tenure depending on whims of your colleagues and administration, no matter how productive you are" "What is your biggest wealth building tool?  Income.  If you ""nerf"" your income with payments to banks, cable, credit card debt, car payments, and lattes then you are naturally handicapping your wealth building.  It is sort of like trying to drive home a nail holding a hammer right underneath the head.   Normal is broke, don't be normal. Normal obtains student loans while getting an education.  You don't have to.  You can work part time, or even full time and get a degree. As an example, here is one way to do it in Florida.  Get a job working fast food and get your associates degree using a community college that are cheap.  Then apply for the state troopers.  Go away for about 5 months, earning an income the whole time.  You automatically graduate with a job that pays for state schools.  Take the next three years (or more if you want an advanced degree) to get your bachelors.  Then start your desirable career. What is better to have ""wasted"" approx 1.5 years being a state trooper, or to have a student loan payment for 20 years?  There is not even pressure to obtain employment right after graduation.  BTW, I know someone who is doing exactly what I outlined. Every commercial you watch is geared toward getting you to sign on the line that is dotted, often going into debt to do so.  Car commercials will tell you that you are a bad mom or not a real man if you don't drive the 2015 whatever.   Think differently, throw out your numbers and shoot for zero debt. EDIT:  OP, I have a MS in Comp Sci, and started one in finance.  My wife also has a masters.  We had debt.  We paid that crap off.  Work like a fiend and do the same.  My wife's was significant.  She planned on having her employer pay it off for each year she worked there.  (Like 20% each year or something.)  Guess what, that did not work out!  She went to work somewhere else!  Live like you are still in college and use all that extra money to get rid of your debt.  Student loans are consumer debt." It's hard to be disciplined when the money is right there to be spent. So what you should do is have two bank accounts. One for savings and one for spending. Figure out how much you need to spend per week and have your pay automatically deposit that much into the spending account and divert the rest into these accounts.  Never touch your savings account unless it is an emergency or whatever. In fact, if you really want, you should put it as a termed deposit which you can't touch. As the only thing you see is your spending balance, you'll be forced to get used to living within your means. After a while, you're going to forget that you have that savings account at all. "There will be many who will judge your proposal on the idea that subsidized loans should be available to those who need them, and should not be used by others who are simply trying to profit from them. Each school has a pool of money available to offer for subsidized and unsubsidized loans. If they are giving you a subsidized loan, they cannot allocate it to someone else who needs it. Once you weigh the investment risks, I agree that it is analogous to investing rather than repaying your mortgage quickly. If you understand the risks, there's no reason why you shouldn't consider other options about what to do with the money. I am more risk averse, so I happen to prefer paying down the mortgage quickly after all other investment/savings goals have been met. Where you fit on that continuum will answer the question of whether or not it is a ""bad idea""."
