<prompt> Human: I have an auto loan 1.99 with 4 years left, I have enough cash to pay off the loan today however, if I put that money into a CD I could earn 2.3 interest, doing the math it makes sense to keep the loan and invest in a CD. Am I thinking right or am I missing something?Edit: No other debt, no mortgage.  <response>: Kinda.The CD interest is taxable. You should compare post-tax rates.
