Loan calculator
Estimate the monthly payment and total cost of a fixed-rate amortized loan, then test whether an additional monthly payment changes the timeline.

Estimate the amortized loan
Use the principal, annual rate, and term in the lender's offer. An optional extra payment shows a simple early-payoff scenario.
What amortization means
Each scheduled payment covers estimated interest for the period and reduces principal. Early payments usually contain more interest because the outstanding balance is larger.
Look beyond the monthly payment
A longer term can reduce the scheduled payment while increasing the total interest paid. Compare monthly affordability, total cost, fees, and how long the obligation remains active.
Extra payments need lender confirmation
Ask whether extra money is applied directly to principal, whether prepayment fees exist, and whether the scheduled payment or loan term changes afterward.
What this estimate leaves out
Origination fees, insurance, taxes, variable rates, balloon payments, and lender-specific rounding are not modeled. Use the formal disclosure for the actual offer.
- Compare offers using the same principal and term.
- Check total repayment, not only the advertised monthly amount.
- Keep the payment beside your other required costs.
Questions people ask next
Why is the final payment different?
Centavo rounding and an extra monthly payment can leave a smaller final balance, so the last payment is adjusted to clear it.
Does the calculator include fees?
No. Add lender fees, insurance, taxes, and other charges separately when comparing the full cost.
Can I use it for zero-interest loans?
Yes. The principal is divided across the term, with the final payment adjusted for rounding.
