How this calculator works

This calculator estimates the monthly payment for a fixed-rate loan using the standard amortization formula.

It also shows how making an extra monthly payment can reduce the total interest you pay and shorten the payoff timeline.

Results do not include taxes, insurance, origination fees, or other loan-specific charges.

How this loan calculator works

This calculator estimates your monthly loan payment using a standard fixed-rate amortization formula. It shows how much you will pay each month, how much of your payment goes toward interest, and how much reduces your principal over time.

You can also add an extra monthly payment to see how it affects your payoff timeline. Even small additional payments can significantly reduce total interest and shorten the life of your loan.

How extra payments reduce your loan

When you make extra payments, more of your money goes directly toward the principal balance. This reduces the amount of interest charged in future months, which accelerates the payoff of your loan.

Over time, this creates a compounding effect in reverse: instead of interest working against you, reducing your balance faster lowers the total cost of borrowing.

Example: Paying off a loan early

Suppose you have a $25,000 loan at 6.5% interest over 5 years. By adding an extra $100 per month, you could pay off the loan months earlier and save hundreds of dollars in interest.

Use the calculator above to adjust the numbers and see how different extra payment amounts affect your results.

Frequently asked questions

How are loan payments calculated?

Loan payments are calculated using an amortization formula that spreads repayment over a fixed number of periods. Each payment includes both interest and principal, with the balance gradually decreasing over time.

Does this include taxes, fees, or insurance?

No. This calculator estimates the core loan payment only. It does not include taxes, insurance, or additional lender fees that may be part of a real loan.

What happens when I add extra monthly payments?

Extra payments go directly toward the principal balance. This reduces future interest charges and shortens the time required to pay off the loan.

Is this calculator accurate?

This calculator provides a close estimate based on standard formulas. Actual loan terms may vary depending on lender rules, payment timing, and additional fees.
