How is it calculated?

The same formulas lenders use, with the rules each program publishes. Nothing is hidden.

The formula

Each month: interest = balance × rate ÷ 12; principal = payment − interest; new balance = balance − principal − extra payments.

What moves the result?

Six things that change the number more than anything else.

  • The price

    Every dollar of price is a dollar more of loan. It is the first thing that moves the payment.

  • The rate

    One point of rate changes the payment for the whole term. Compare at least three offers.

  • The term

    Over 15 years you pay more per month and far less interest in total than over 30.

  • Extra payments

    A little more principal each month shortens the term and lowers the total interest.

  • Time

    At first almost all of the payment is interest; over the years, more and more goes to principal.

  • Mortgage insurance

    FHA always charges it; conventional loans only with less than 20% down.

Frequently asked questions

Why is almost all of my payment interest at first?

Because interest is figured on what you owe, and at first you owe almost all of it. Each payment leaves you owing a little less, so the interest drops and a bigger part of the same payment goes to principal.

What saves more: paying extra every month or once a year?

It depends on how much you pay and when: money paid earlier saves more interest. Put both options in the tool and compare. Before paying extra, it helps to have an emergency fund.

Will my lender give me the same schedule?

It should look very close. It can differ by cents from rounding, or more if your rate is adjustable, a payment arrived late or your lender applies payments differently. Your statement is the one that counts.

Do you keep my numbers?

No. Everything stays in your browser and you can clear it with the start-over button. We never ask for names or personal data.

Methodology and sources (Freddie Mac and the Census Bureau)

  1. The monthly payment: from the loan amount, the rate and the term we use the fixed-rate loan formula, the same one as the mortgage calculator. It counts principal and interest only.
  2. Each month: the interest is what you owe times the yearly rate divided by 12. The rest of the payment lowers what you owe (the principal). That is why almost all of the payment is interest at first.
  3. Extra payments go entirely to principal: the monthly extra, the once-a-year extra (we add it in the last payment of each loan year) and the one-time payment in the payment number you choose. They never pay more than you owe.
  4. What you save: we build the same schedule without extra payments and compare. The difference in interest and in months is your saving. The example loan is the typical home value less the FHA minimum down payment (3.5%); replace it with yours.
