About This Tool
Why use Loan Calculator?
This loan calculator shows the fixed monthly payment for any amortizing loan, such as a car loan, personal loan or mortgage, plus the total interest you will pay. It also shows what happens when you add an extra payment each month.
Extra payments go straight to principal, which shortens the loan and reduces interest. For example, a 250,000 loan at 6.5% over 30 years has a payment of about 1,580.17. Adding 200 a month pays it off 95 months early and saves roughly 97,600 in interest.
Key Benefits
Early payoff analysis
See exactly how many months and how much interest an extra monthly payment saves.
Works for any fixed-rate loan
Car loans, personal loans, student loans and mortgages all use the same amortization math.
True cost of borrowing
Total interest is shown next to the payment, so a low monthly figure cannot hide an expensive loan.

Loan Calculator FAQs
What formula does the loan calculator use?
It uses the standard amortization formula M = P × r(1 + r)^n ÷ ((1 + r)^n − 1), where r is the monthly rate and n is the number of payments. With extra payments it simulates the balance month by month.
Is it worth making extra loan payments?
Usually, yes, if the loan has no prepayment penalty and you have an emergency fund. Every extra amount reduces the principal that interest is charged on, so savings grow over time.
Should I compare loans by rate or APR?
APR. It includes most fees, so it reflects the real cost of borrowing better than the headline interest rate.
