Loan Interest Calculator

Enter loan amount, repayment period (years), and interest rate, then select repayment method (equal principal and interest or equal principal) to calculate monthly repayment amount and total interest.

Equal principal and interest pays the same amount monthly, while equal principal adds interest to the same principal monthly. Equal principal has higher initial burden but less total interest.

If you have initial cash flow flexibility, equal principal is advantageous with less total interest. If you prefer consistent monthly amounts, equal principal and interest is more convenient.
