    Loan installment calculation

    Before taking out a loan, knowing your monthly payment burden and the total cost is essential for budget planning. This tool uses the equal-installment (annuity) method to calculate your monthly installment, total repayment, and the total interest you will pay.

    Enter the interest rate as a monthly rate. You can find the approximate monthly rate by dividing the annual rate by 12.

    Frequently Asked Questions

    For equal-installment (annuity) loans, the monthly installment is calculated with the formula principal × monthly rate ÷ (1 − (1 + monthly rate)^−term). With this method the amount paid each month is fixed; the share of interest is higher at the start and the share of principal is higher towards the end.

    Total interest is found by subtracting the principal borrowed from the sum of all installments you will pay over the term. As the term gets longer the monthly installment decreases, but the total interest paid increases.
