Personal Loan Calculator estimate

Enter values, then calculate.

How the estimate works

The monthly payment uses the standard fixed-rate amortization formula. The estimated origination fee is shown separately from interest.

Important limitation

Some lenders deduct origination fees from proceeds while requiring repayment of the full face amount. Results are estimates only and are not financial, lending, legal, tax, or investment advice.
