This calculator returns the fixed monthly payment, total interest, and total cost of a loan given its amount, annual rate, and term in months. Use it to size a personal, auto, or installment loan payment before you sign, or to see the lifetime interest a given rate adds.

How this is calculated

It uses the standard amortizing-loan payment formula, Payment = P*r*(1+r)^n / ((1+r)^n - 1), where r is the annual rate divided by 12 and n is the number of months; at a 0% rate the payment is simply the amount divided by the term.

How to use

  1. Enter the loan amount.
  2. Enter the annual interest rate and term in months.
  3. Read the monthly payment, total interest, and total paid.

Examples

  • $10,000 at 5% / 36 mo: payment $299.71
  • 0% interest: $5,000 over 12 mo → $416.67

FAQ

How is the monthly payment calculated?
Payment = P·r·(1+r)^n / ((1+r)^n − 1), where P is the amount, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of months.
What is total interest?
The total paid over the full term minus the original loan amount, the cost of borrowing.
Does it work for a 0% loan?
Yes. At 0% the payment is simply the amount divided by the number of months.
