Use our Mortgage Amortization Calculator to view a complete loan amortization schedule and understand how every mortgage payment is applied throughout the life of your loan. Whether you’re buying a new home, refinancing, or making extra payments, this calculator helps you see how your mortgage balance decreases over time.
Instantly generate a detailed loan amortization schedule, compare payment scenarios, and discover how additional monthly payments can reduce both your interest costs and your loan term.
What Is a Mortgage Amortization Schedule?
A mortgage amortization schedule is a complete payment timeline that shows how each monthly payment is divided between principal and interest. At the beginning of a mortgage, a larger portion of each payment goes toward interest. As the loan balance decreases, more of your payment is applied to the principal.
Using a mortgage calculator with amortization makes it easier to understand exactly how your loan will be repaid from the first payment to the last.
How the Mortgage Amortization Calculator Works
Our calculator uses the standard mortgage amortization formula commonly used by banks and mortgage lenders in the United States.
Simply enter your mortgage details:
- Home purchase price
- Down payment
- Loan amount
- Interest rate
- Loan term (15, 20, or 30 years)
- Extra monthly payment (optional)
Once calculated, you’ll receive a complete amortization table showing every payment over the life of your mortgage.
Understanding Your Loan Amortization Schedule
Each payment in your amortization schedule includes several important values:
Payment Number
Shows the order of every monthly payment from the beginning of your mortgage to the final payoff.
Principal Paid
The portion of your payment that reduces your loan balance.
Interest Paid
The amount paid to your lender as the cost of borrowing money.
Remaining Balance
Displays how much you still owe after each payment.
Benefits of Using a Mortgage Calculator with Amortization
- See how your loan balance changes every month.
- Understand how much interest you’ll pay.
- Track principal reduction over time.
- Plan future refinancing opportunities.
- Compare different mortgage terms.
- Estimate your total borrowing cost.
Mortgage Calculator with Extra Payments
Making additional monthly payments can significantly reduce both your total interest costs and the length of your mortgage.
Our mortgage calculator with extra payments lets you enter an additional payment amount and instantly see how much money and time you could save.
Even a small extra payment each month may shorten a 30-year mortgage by several years while saving thousands of dollars in interest.
Example of Extra Mortgage Payments
| Monthly Extra Payment | Potential Interest Savings | Estimated Time Saved |
|---|---|---|
| $50 | Moderate | Several months |
| $100 | High | 1–3 years |
| $250 | Very High | Several years |
Actual savings depend on your interest rate, loan amount, and remaining loan term.
