Loan Payment Calculator (USA)
Estimate your payment, total interest and payoff time for any fixed-rate loan. Compare monthly, bi-weekly or weekly schedules, and see how extra payments cut your interest and shorten the term.
Bi-weekly and weekly schedules pay off faster because you make more payments each year.
Added to every scheduled payment. The results will show the interest and time you save.

How to Use This Calculator
Three short sections, five inputs — and the calculator instantly shows your payment, total interest, payoff time, and a full year-by-year amortization schedule, plus how extra payments cut your interest and shorten the term.
Enter your loan amount and rate
Type or use the slider to set the amount you’re borrowing and your interest rate (APR). Use the rate your lender quoted, or a current market rate for the type of loan you’re planning.
Choose your term and frequency
Select a loan term from 1 to 40 years, then pick a monthly, bi-weekly, or weekly schedule. More frequent payments pay the loan off faster and reduce total interest.
Add any extra payment
Optionally enter an extra amount to add to every payment. The results instantly show how much interest you save and how many years sooner the loan is paid off.

Key Loan Facts Every Borrower Should Know
Three Borrowers Who Use This Calculator
Whether you’re taking out a mortgage, financing a car, or trying to pay off debt faster, knowing your real payment and interest cost helps you decide with confidence. Here’s how three common profiles use this calculator.
Priya is comparing a 30-year and a 15-year mortgage on a $350,000 loan. She wants to see how much the monthly payment rises on the shorter term — and how much total interest she’d save by choosing it.
- Enter the loan amount and rate, then switch the term between 30 and 15 years to compare
- Watch the total interest figure to see the long-term saving of a shorter term
- Try a slightly lower rate to see how much a better quote is really worth
- Download the PDF to bring real numbers to your loan officer conversation
Marcus is financing a $32,000 car and needs a monthly payment that fits his budget. He wants to test 5-year versus 7-year terms and see how the total interest changes at each length.
- Enter the vehicle loan amount and the dealer or bank’s quoted APR
- Compare 5-, 6-, and 7-year terms to find a payment that fits comfortably
- Note how a longer term lowers the payment but raises total interest
- Add a small extra payment to see how quickly you can be debt-free
Elena has a personal loan and some spare cash each month. She wants to know exactly how much interest she’ll save and how much sooner she’ll be free if she adds extra to every payment.
- Enter your current balance, rate, and remaining term as the baseline
- Add different extra-payment amounts to compare interest saved at each level
- Switch to a bi-weekly schedule to see the added acceleration effect

7 Ways to Pay Less Interest on Your Loan
Small, deliberate changes to how you borrow and repay can save thousands in interest and clear your loan years early. These seven strategies help you get there faster.
Make Extra Payments Toward Principal
Even $100–$200 extra per payment goes straight to your balance, reducing interest in every future period. Use the extra-payment field to see exactly how many years and how much interest you save.
Switch to a Bi-Weekly Schedule
Paying every two weeks results in 26 payments a year — about one extra monthly payment — which can shave years off a long loan. Confirm your lender applies the extra to principal with no fee.
Choose the Shortest Term You Can Afford
A shorter term means a higher payment but dramatically less total interest. Compare a 15-year and 30-year loan in the calculator to see whether the larger payment fits your budget.
Shop and Negotiate Your Rate
Even half a percentage point off your APR can save thousands over the life of a loan. Get quotes from several lenders and use the rate field to compare the true cost of each offer.
Round Up Your Payment
Rounding a $1,430 payment up to $1,500 is an easy, painless way to add extra principal every period. The calculator shows how these small round-ups compound into a large interest saving.
Apply Windfalls to the Balance
Tax refunds, bonuses, and gifts make ideal one-time principal payments. Add an equivalent amount as extra in the calculator to preview how a single lump sum changes your payoff date.
Avoid Stretching the Term to Lower Payments
Extending a loan reduces the monthly payment but increases total interest and keeps you in debt longer. Use the term selector to weigh the real long-term cost before choosing a longer schedule.
