How this loan calculator works
For example, a $50,000 loan at 6.5% over 5 years produces an estimated monthly payment based on monthly amortization.
Important: Review the assumptions shown under each input. Changing one assumption can materially change the result.
When to use this calculator
- Compare two loan amounts, rates or terms before you accept an offer.
- See how much of the first payment goes to interest versus principal.
- Use the schedule to judge total interest, not just the monthly payment.

Frequently asked questions
Does a lower monthly payment mean a cheaper loan?
Not necessarily. A longer term can cut the payment while increasing total interest.
Is the rate field the same as APR?
No. It is a nominal annual rate divided by 12. Fees that belong in an APR are not included.
Why might a lender quote a different payment?
Lenders may use different day-count rules, fees, insurance or a different final-payment rounding convention.
