What an amortization schedule shows

A fixed-rate loan has the same payment every month, but the split inside it changes. Each month the interest is the balance times the monthly rate, and the rest of the payment reduces the balance. Because the balance starts high, the first payments are mostly interest, and the share going to principal grows slowly at first and faster later.

That is why a 30-year loan builds equity slowly in the early years, and why the total interest over the life of the loan can approach or exceed the amount borrowed at higher rates.

How extra payments change the schedule

Extra money sent with a payment goes straight to principal when your servicer applies it that way. A lower balance means less interest next month, so each extra dollar saves more than a dollar over the life of the loan, and the loan ends sooner. Ask your servicer to apply extra payments to principal and check that there is no prepayment penalty.

How we calculate it

Payment M = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1] with r the monthly rate and n the number of payments. Interest and payments are rounded to the cent each month, and the last payment clears any rounding remainder. See the methodology page for details.

Frequently asked questions

Why is so much of my early payment interest?

Interest is charged on the outstanding balance, which is highest at the start. On a 30-year loan at a rate near 7%, roughly three quarters of the first payment is interest.

Does the schedule include taxes and insurance?

No. It covers principal and interest only. Escrow items such as property tax and homeowners insurance are added to your monthly payment but do not change the loan balance.

Can I use this for a car loan or personal loan?

Yes. Any fixed-rate loan with equal monthly payments amortizes the same way. Enter the loan amount, rate and term.
