How it works

Personal loans are fixed-rate, fixed-term installment loans, so your monthly payment stays the same for the life of the loan. This calculator uses the standard amortization formula to split each payment between interest and principal.

Because personal loans are usually unsecured (no collateral), their rates are higher than mortgages or auto loans but lower than most credit cards — which makes them a common tool for consolidating high-interest debt.

Always check whether a loan has an origination fee or prepayment penalty. An origination fee raises your effective cost, while a prepayment penalty reduces the benefit of paying the loan off early.

Example: Borrowing $15,000 at 11.5% APR over 3 years costs about $495/month and roughly $2,800 in total interest.

Frequently asked questions

How is a personal loan payment calculated?
It uses the standard amortization formula based on your loan amount, interest rate, and term. Each payment covers interest first, with the rest reducing the principal.
Does paying off a personal loan early save money?
Usually yes, as long as there is no prepayment penalty. Paying early reduces the interest you owe. Check your loan agreement first.
