What is an amortization schedule?

An amortization schedule shows every payment across the loan term, split into how much goes to interest versus principal, and the remaining balance after each payment.

How much of my payment goes to principal?

It grows every month. Early on most of the payment is interest; by the final years nearly all of it is principal, because the balance keeps shrinking and the interest charge shrinks with it.

How to Read a Mortgage Amortization Schedule

Your amortization schedule is a 360-row table that looks like a tax form and reads like a confession: it makes visible exactly how slowly a mortgage builds equity. Learn to read it and you'll understand your whole loan in one glance.

The five columns

Column	What it tells you
Month / Year	Which payment in the term you're looking at
Payment	Your fixed P&I amount (unchanged on a fixed-rate loan)
Principal	Portion actually reducing what you owe
Interest	Portion going to the lender as cost
Balance	Loan balance left after that payment

The pattern to look for

Principal and interest trade places down the schedule. Early rows show tiny principal and towering interest; later rows reverse. On a 30-year loan the crossover — where principal finally exceeds interest — usually happens around the 20-year mark. Before that, the schedule is quietly charging you heavily to hold the money.

What the schedule won't say

It ignores taxes, insurance and HOA — those aren't part of loan amortization. And it'll happily "charge" you 360 months of interest if you never make an extra payment. The schedule is a map; extra principal payments let you redraw the route.

Find your own crossover

Enter your terms in the HomMetra calculator, switch the schedule from yearly to monthly, and scroll until the principal column overtakes interest. That's the moment your equity genuinely starts accelerating — and the strongest argument for any extra payment you can afford early.
