Amortization Calculator

An amortization calculator shows how loan payments are split between principal and interest over time. Early payments are mostly interest; later payments are mostly principal. Formula uses fixed payment amount: M = P[r(1+r)^n]/[(1+r)^n-1]. View complete payment schedule showing balance reduction each month. A $200,000 mortgage at 6% over 30 years has $1,199 monthly payment with $231,676 total interest.

Calculate loan amortization schedules with monthly payment breakdown. See principal, interest, and remaining balance for each payment. Add extra payments to see how they reduce your loan term and total interest. Compare with vs without extra payments. Export schedule as CSV.

Amortization Tips

  • Early payments in a loan go mostly toward interest, not principal
  • Even small extra payments can save thousands in interest over the loan life
  • Biweekly payments (paying half monthly amount every 2 weeks) result in one extra payment per year
  • Refinancing to a lower rate can significantly reduce total interest
  • Compare total cost, not just monthly payment, when choosing loan terms

Frequently Asked Questions

What is an amortization schedule?
An amortization schedule is a table showing each loan payment broken down into principal and interest over the life of the loan. Early payments consist mostly of interest, while later payments go primarily toward principal. The schedule shows the remaining balance after each payment, helping you understand exactly how your loan is being paid off.
How is a monthly loan payment calculated?
Monthly payments are calculated using the formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan principal, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments. For example, a $250,000 loan at 6.5% for 30 years has a monthly payment of $1,580.17.
How do extra payments reduce my loan?
Extra payments go directly toward reducing the principal balance, which means less interest accrues on future payments. For example, adding $200/month to a $250,000 loan at 6.5% over 30 years saves approximately $93,000 in interest and pays off the loan about 7 years early. Even small extra payments early in the loan have a significant impact.
Why does more of my payment go to interest at the beginning?
Interest is calculated on the remaining balance each month. When your balance is highest (at the start of the loan), the interest charge is largest, leaving less of your fixed payment for principal. As you pay down the balance, less goes to interest and more to principal. This is why extra payments early in the loan save the most money.
What is the difference between amortization and simple interest?
An amortized loan has fixed payments that include both principal and interest, with the ratio changing over time. Simple interest is calculated only on the original principal. Most mortgages, car loans, and personal loans use amortization. Credit cards and some short-term loans may use simple interest.
Should I make extra payments or invest the money?
Compare your loan interest rate to expected investment returns. If your loan rate is 6.5% and investments earn 8-10%, investing may be better mathematically. However, paying off debt is a guaranteed return equal to your interest rate and reduces financial risk. Many people benefit from a balanced approach: making some extra payments while also investing.
