About this calculator
A free fixed-rate loan calculator for personal and installment loans. It applies standard amortization to turn a loan amount, APR, and term in months into a level monthly payment, then shows the total interest and the total of all payments over the life of the loan. Use it to compare how the rate and term change what a loan really costs. It runs entirely in your browser and is an estimate, not a loan offer or APR quote.

Questions
- How is the monthly payment calculated?
- With the standard amortization formula for a fixed-rate loan: the payment is constant each month, and the split between interest and principal shifts toward principal over time.
- Does it include fees?
- No. The estimate covers principal and interest only. Origination fees, payment protection, and late charges are not modeled, so the true cost of a loan with fees will be higher.
- Is it free and private?
- Yes. There is no account and no upload — the amount, rate, and term you enter are calculated in your browser and never stored.
