What this loan calculator includes

Monthly payment

The calculator estimates a fixed monthly payment from loan amount, annual percentage rate, and repayment term.

Total repayment

Seeing total repayment helps compare the real cost of different terms, not just the monthly payment.

Extra payment scenario

Adding even a small extra monthly payment can reduce interest and shorten payoff time when the lender applies it to principal.

How to compare loan scenarios

Compare terms, not only payment size

A longer term can lower the monthly payment but increase total interest. A shorter term can cost more each month but reduce total repayment.

Check fees and penalties

Origination fees, prepayment penalties, late fees, and insurance products can change the real cost of a loan. This page estimates payment math, not every contract term.

Use extra payment cautiously

Extra payments are useful only if your budget can support them and your lender applies them to principal without penalty. Confirm rules before relying on the savings estimate.

Educational estimate only

This loan calculator is for educational estimates only. It is not financial, tax, legal, lending, or investment advice. Actual loan costs can vary by lender, credit profile, fees, payment timing, prepayment rules, and local requirements.

Loan calculator FAQ

What kinds of loans can this estimate?

It works best for simple fixed-rate installment loans such as personal loans, auto loans, and similar repayment plans. It is not designed for credit cards, variable-rate loans, or interest-only loans.

Does the result include loan fees?

No. The result estimates principal and interest only. Add lender fees, origination fees, insurance, taxes, or penalties separately when comparing real offers.

How does the extra payment estimate work?

The calculator adds the extra amount to the scheduled payment and estimates how much interest and time could be saved if the extra payment reduces principal each month.

Why might my lender payment be different?

Lenders may use exact dates, fees, rounding rules, credit-based pricing, insurance, and other terms that are not included in this simplified estimate.
