# Mortgage amortization schedule calculator

See every payment on your loan with its date, how much goes to principal and interest, and the balance after it. For a loan you already have, it shows where you are today.

## What an amortization schedule shows

Amortization means paying off a loan in equal installments over a set term. Each monthly payment on a fixed-rate mortgage is the same, but what it pays for changes: part covers the interest charged that month and the rest pays down the balance, which lenders call principal. An amortization schedule, or mortgage amortization table, lists every payment with its date, that split, and the balance left after it, from the first payment to the last.

## How each month's interest is worked out

Interest is charged on what you still owe. Each month the lender takes the balance, multiplies it by the annual rate and divides by 12, rounded to the cent. Whatever is left of your payment reduces the balance, and the next month starts from that lower number.

Take $400,000 at 6.5% for 30 years. The payment is $2,528.27. In month one the interest is $400,000 × 6.5% ÷ 12 = $2,166.67, so only $361.60 goes to principal. In month two the balance is $399,638.40, interest is $2,164.71, and principal rises to $363.56. That pattern repeats for all 360 payments.

## Why early payments are mostly interest

Because interest is charged on the balance, it's largest when the balance is largest: at the start. As the balance slowly falls, interest shrinks and more of the same payment goes to principal. Here is the same $400,000 loan, year by year:

| Loan year | Interest paid | Principal paid | Share that's interest | Balance at year end | | --- | --- | --- | --- | --- | | Year 1 | $25,868 | $4,471 | 85% | $395,529 | | Year 5 | $24,545 | $5,794 | 81% | $374,444 | | Year 10 | $22,327 | $8,013 | 74% | $339,105 | | Year 15 | $19,259 | $11,080 | 63% | $290,237 | | Year 20 | $15,018 | $15,321 | 49% | $222,662 | | Year 25 | $9,153 | $21,187 | 30% | $129,218 |

Calculated with the same engine as the calculator above.

Over the first ten years you'd pay $242,497 in interest but only $60,895 off the loan. Payment #233, 19 yrs 4 mo in, is the first that is more principal than interest. The [principal vs interest calculator](https://ownedoutright.com/us/principal-vs-interest-calculator/) finds that crossover month for your own loan.

## How to read your own schedule

- **Payment** is principal and interest only. Your bill is usually higher because escrow for taxes and insurance is added on top.
- **Principal** is the part that lowers your balance. **Interest** is the lender's charge for that month.
- **Balance** is what you owe after that payment. It's close to the payoff amount, but a payoff quote also adds interest up to the day you pay.
- **Total interest** is a running total. Your servicer reports the interest you paid each calendar year on Form 1098; the yearly view gives a close estimate.

If your first payment was in the past, the calculator highlights this month's row and shows what you've paid so far and what you should owe now. Compare that with your latest statement. A lower balance usually means you've paid extra at some point; a higher one can mean missed payments or fees.

## Dates on your schedule

A loan amortization schedule with dates starts from your first payment, not your closing date. US mortgage interest is paid in arrears, so each payment covers the month before it. If you close in mid-March, you usually prepay interest for the rest of March at closing, and your first full payment is due on May 1. That payment pays April's interest. Your Closing Disclosure and first statement both show the first due date.

For a loan you already have, pick that first payment month. The schedule then lines up with your real calendar, so the yearly view matches the tax years on your Form 1098 and the payoff month is the one you can plan around.

## A printable amortization schedule

The Print schedule button prints the headline numbers and the table, without the form or the rest of this page. The monthly view runs to several pages for a 30-year loan; the yearly view usually fits on one or two. To keep a copy, choose "Save as PDF" in your browser's print dialog, or download the CSV to work with every row in a spreadsheet.

## How extra payments change the schedule

Any extra you pay goes straight to principal. That lowers next month's interest, so more of every later payment goes to principal too, and the schedule ends early. The required payment doesn't change. On the example loan, paying $200 extra a month from the start ends it 5 yrs 7 mo early and saves $111,893 in interest.

Open "Add an extra monthly payment" in the form to see it in your schedule. To model yearly extras, lump sums or a payoff date from today's balance, use the [extra payment calculator](https://ownedoutright.com/us/extra-payment-calculator/), and read [how to make extra mortgage payments](https://ownedoutright.com/us/guides/how-to-make-extra-mortgage-payments/) so your servicer applies them to principal.

## Questions people ask

### How do I make an amortization schedule for a loan I already have?

Enter the original loan amount, your rate, the term and the month of your first payment. The calculator rebuilds the whole schedule, highlights this month's payment, and shows the interest and principal you've paid so far and the balance you should owe today. If you've made extra payments in the past, your real balance will be lower; the extra payment calculator can start from your statement balance instead.

### Why doesn't my balance match my mortgage statement exactly?

Small differences are normal. Servicers may round differently, charge interest daily, or apply a payment on a different day. Late fees, past extra payments and escrow shortages also change the numbers. If the gap is more than a few dollars, ask your servicer for their own amortization schedule.

### Does the amortization schedule include taxes and insurance?

No. The schedule covers principal and interest only, which is what pays down the loan. Property taxes, homeowners insurance and mortgage insurance are usually collected through escrow on top of this, and they don't affect how the balance falls.

### How do I print or save my amortization schedule?

Use the Print schedule button to print the table, or save it as a PDF from your browser's print dialog. Switch to the yearly view first for a one- or two-page summary. Download CSV gives you every monthly row to open in Excel, Numbers or Google Sheets.

### When does my payment start going mostly to principal?

It depends only on your rate and term, not the loan size. On a 30-year loan at 6.5%, it takes about 19 years. The yearly chart above marks the month, and the principal vs interest calculator shows it for any loan.
