Note: values hardcoded for readability only.
rate - The interest rate per period. We divide 5% by 12 because 5% represents annual interest. nper - the total number of payment periods for the loan, 60. pv - The present value, or total value of all payments now, 30000. start_period - the starting period for a given year. end_period - the ending period for a given year.
In the range F5:F9, here are the formulas used: Note many values could be picked up directly with cell references, but are hardcoded in this example for readability.
Other periods
In this example, we are calculating interest by year, so periods are set up accordingly. However, you can adjust periods to calculate interest in any timeframe desired.
