Build a loan calculator with an amortization table that splits every payment into interest and principal, tracks the balance and totals the interest by year.
In this lesson

- Lock the inputs with $ and leave the month number relative, then copy one row down the whole table.
- Interest over a span of payments:
=-CUMIPMT(rate/12, years*12, amount, first, last, 0).
