Loan Repayment Calculator

Calculate loan repayments, total interest and overall borrowing cost. Enter your loan amount, interest rate and repayment term to estimate your periodic payment.

The amount borrowed.

%

Annual interest rate charged on the loan.

years

The repayment period for the loan.

How frequently repayments are made.

Loan Repayment Formula

Periodic Payment = P × [r(1 + r)ⁿ] ÷ [(1 + r)ⁿ − 1] Where: P = Loan amount r = Periodic interest rate = Annual rate ÷ payments per year ÷ 100 n = Total number of payments = Loan term × payments per year Total Repayment = Periodic Payment × n Total Interest = Total Repayment − Loan Amount If the interest rate is 0%: Periodic Payment = Loan Amount ÷ n

The calculator uses a standard amortizing-loan formula. Actual repayment amounts can differ when fees, insurance, variable rates, taxes or lender-specific charges apply.

Example Loan Repayment Calculation

500,000 loan at 7% for 10 years with monthly repayments

Given:

  • Loan Amount = 500,000
  • Annual Interest Rate = 7%
  • Loan Term = 10 years
  • Payments Per Year = 12

Periodic rate:

7% ÷ 12 = 0.583333% per month

Total payments:

10 × 12 = 120 payments

Result: Periodic Payment ≈ 5,805.42

Total Repayment ≈ 696,650.40.

Total Interest ≈ 196,650.40.
