Help! I have Excel worksheets I made with formulas set up using PMT to figure out payments if we were to finance something using various months and interest rates. However, I cannot figure out how to put in an amount we owe (like a credit card) and figure out how soon it would be paid off if we paid so much a month or how much we'd have to pay to get it paid off in a certain time period. Can anyone help me? I think it's using the FV, but I didn't retain anything from my college finance class!!
