A loan calculator helps you estimate the monthly payment, total interest and the full cost of a loan in advance. Knowing the payments, a borrower can easily find a comfortable amount and term that fit their budget.
Enter the loan amount, the term in months and the interest rate (your bank quotes the rate at pre-approval). Choose the payment type — annuity or differentiated — and the calculator instantly shows the monthly payment, interest overpayment and a full month-by-month payment schedule.
With an annuity payment the monthly amount stays the same for the whole term: at first you mostly pay interest, towards the end — the principal. With a differentiated payment the principal is repaid in equal parts, so the payment decreases every month and the total interest is usually lower — but the first payments are noticeably higher.
The calculator supports several early repayments, each with a month and an amount. You can choose the recalculation method: reduce the payment (same term, lighter load) or reduce the term (same payment, the loan ends sooner). The latter is usually more beneficial. The payment schedule shows how the payment changes after each early repayment.
The loan rate depends on the central bank key rate, the loan type (an unsecured cash loan is usually more expensive than a mortgage) and the borrower’s profile: credit history, income and payroll-client status. Many banks give payroll clients a discount of 0.3–0.6 percentage points.
The monthly payment is calculated as A = P × r / (1 − (1 + r)−n), where P is the loan amount, r is the monthly rate (annual / 12) and n is the term in months. For example, a loan of 500,000 at 25% per annum for 3 years: payment ≈ 19,902, overpayment ≈ 216,462.
The calculation is preliminary. Check the exact terms with your bank.
