This payment calculator tells you the exact monthly payment for any loan based on the amount borrowed, interest rate, and loan term. Whether you are figuring out payments for a mortgage, car loan, personal loan, or any other installment debt, the underlying math is the same. Enter your numbers to see your payment instantly.
The Payment Formula
All fixed monthly payments use the same amortization formula. Your payment is calculated so that equal monthly amounts will pay down exactly the loan principal plus all interest over the term. This is why the payment stays constant even as the interest/principal split shifts each month.
Monthly Payment = P × [r(1+r)^n] / [(1+r)^n - 1] P = Principal loan amount r = Monthly interest rate (annual rate / 12) n = Total number of payments (years × 12)
For a $20,000 loan at 6% for 5 years: r = 0.005, n = 60. Monthly payment = $386.66.
How Loan Term Affects Payment
Longer terms mean lower monthly payments but more total interest paid. Shorter terms mean higher payments but significant interest savings. There is always a tradeoff between cash flow today and total cost over the life of the loan.
| $20,000 at 6% | Monthly Payment | Total Interest |
|---|---|---|
| 2 years | $886 | $264 |
| 3 years | $608 | $1,000 |
| 5 years | $387 | $2,200 |
| 7 years | $291 | $4,450 |
Frequently Asked Questions
What is the difference between APR and interest rate?⌄
The interest rate is the base cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate plus any fees (origination fees, closing costs, etc.), expressed as a yearly rate. APR gives a more complete picture of the loan's total cost. Always compare APRs when shopping for loans.
How do I lower my monthly payment?⌄
Three ways: borrow less, get a lower rate, or extend the term. Extending the term reduces the payment but increases total interest paid. Getting a lower rate through a better credit score or shopping multiple lenders saves money on both payment and total interest. Making a larger down payment reduces the amount borrowed.
Does making extra payments change my monthly payment?⌄
No. Your required monthly payment stays fixed. Extra payments reduce your principal balance, which means you pay less interest over time and pay off the loan early. Your monthly payment obligation does not change unless you formally refinance the loan.
What happens if I miss a loan payment?⌄
Most lenders offer a grace period of 10-15 days before a late fee applies. After 30 days, the missed payment is typically reported to credit bureaus, damaging your score. After 90+ days, lenders may send the account to collections or begin default proceedings. Contact your lender immediately if you anticipate missing a payment. Most have hardship programs.
