<prompt> Human: Hi guys. I bought a new car 2015 Corolla recently, for about 15K after fees and taxes. I put a 6,000 down payment down, so the total loan is now 9,000, and the first payment is due on March 7.The reason Im writing this is because I have a very high interest rate on the car. This is for a few reasons.1. Im self-employed, and could not provide any pay stubs or proof of employment, even though I make 40-45k per year, and had 0 debt before the car loan from credit cards, loans, or medical bills, or any other sources. 2. I had no active credit accounts until last month, when I signed up for a credit card with a ridiculously low 500 limit. Previously, I had two student loans, which I repaid in 2015. I have had no open credit accounts since then which I realize now was a mistakeFor these two reasons, I showed up in the Toyota credit system as essentially having a 0 credit score. I was also unable to get pre-approved by several lenders, so this did not surprise me. I needed the car, so I figured that I should just take this hit, and start paying off the car as soon as I can, so I signed the paperwork. However, I also want to build up my credit score. I have enough cash to buy the car outright and pay off the remainder of my loan -- now, if I wanted. I have 8.5K in a checking account, and 12K in a high-yield Discover savings account. Obviously, it would not be ideal to blow all of this money on a car. So, currently, my plan is to drop 5-6K towards the loan on my first payment due date. This way, I could reduce the 212 monthly payment, and save about 2k in interest over the lifetime of the loan.Doing so would drop the monthly payment significantly. Then, I would pay 250-300 more than the monthly payment every month, until the car is paid off, which would take a little bit over a year.I may even refinance within 3-4 months, if thats long enough to build a solid credit score, and get a much lower APR.My question is this. Is this a good idea? I know 14.5 APR is insanely high, but if I put a lot of money towards my loan during my first payment, is it worth paying a high APR for a few months in order to help build up my credit score? Or am I better off pulling money from my savings, and paying down the entire loan now? I would still have enough money for a rainy day fund and my Q1 quarterly freelance taxes -- but that would be about it. Any input you have would be valuable. I appreciate it.EDIT:Thanks for the feedback, guys. I think Im going to try to pay off the loan immediately. I should easily have 6-12 months of emergency cash left over, and if I think about it as a 14.5 ROI, it makes a lot more sense then just sitting on my money for no reason, while paying egregious interest rates.  <response>: At that interest rate you should pay the whole loan off.Use what you would have paid in car payments to re-load your savings accounts.Good luck.
