Calculate the annual interest rate on a $250,000 loan requiring 25 years to fully amortize with monthly payments of $2,633.06.
1. PV = 250,000
N = 25 * 12 = 300 monthly payments
PMT = -2,633.06
We input PMT with a negative sign as it is a cash outflow
FV = 0
CPT I/Y
I/Y is the interest rate per period
I/Y = 1.00% per month
Annual interest rate = 1.00% * 12
Annual interest rate = 12%
