How this calculator works

An installment loan is repaid in equal monthly payments, and this calculator fixes that payment from three inputs: the amount borrowed, the annual interest rate, and the term in months. It uses the standard amortization formula lenders use for fixed-rate loans.

Total paid is the monthly payment multiplied by the number of months, and total interest is that total minus the amount borrowed. A longer term lowers the monthly payment but raises total interest, because you pay interest for more months. A shorter term does the opposite.

Enter your own rate, since rates vary by lender, loan type, and credit profile. Use this to compare a personal loan, an auto loan, or any other fixed-rate offer on equal terms.

Frequently asked questions

What is the difference between the payment and the total paid?
The monthly payment is what you pay each month, while the total paid is every payment added together. The gap between total paid and the amount borrowed is the interest you pay over the term.
Does a lower payment always mean a cheaper loan?
No. A lower payment often comes from a longer term, which means more months of interest and a higher total. Compare the total paid as well as the monthly payment before choosing.
What happens if the interest rate is 0%?
With no interest, the payment is simply the amount borrowed divided by the number of months, and total interest is zero. The formula simplifies cleanly to that result.
Can I use this for any installment loan?
Yes, as long as it is a fixed-rate loan with equal monthly payments and no fees built into the payment. Fees are handled separately in the APR calculator and the personal loan calculator.
