About this template
Your mortgage is probably the biggest number in your life — and the most expensive to guess at. This Google Sheets calculator shows your full amortization schedule, year-by-year totals and side-by-side plan comparisons, then answers the question every homeowner asks: what happens if I pay a little extra each month? Add an extra payment or a lump sum and watch your payoff date move years earlier and your total interest drop by thousands.
