But the program uses a correct formula. I'd write it this way: \[\begin{align} n~&=~log_{~1+i}~(1\frac{i \cdot PV}{PMT}) \\ \\ &=~ \frac{ln(1\frac{i \cdot PV}{PMT})}{ln(1+~i)} \end{align}\] This is what the program correctly implements. Assuming that the user enters the monthly payment and the annual interest rate. Dieter
