payment = amount × r ÷ (1 − (1 + r)^(−n)), r = annual rate ÷ 12 ÷ 100
The calculator uses the standard annuity repayment model used by most banks: the payment is the same every month, while the ratio of interest to principal inside it shifts over time. Early on, most of the payment covers interest; near the end, almost all of it repays principal.
In the formula, r is the monthly interest rate (annual nominal rate divided by 12 and by 100) and n is the number of monthly payments.

For a 50,000 KM loan at a 6% nominal annual rate over 10 years (120 payments), the monthly payment is about 555 KM. You repay about 66,612 KM in total, of which roughly 16,612 KM is interest. Shorten the term to 7 years and the payment rises to about 730 KM, but total interest drops to about 11,355 KM — a shorter term always means less total interest.
Nominal vs. effective interest rate
This calculator works with the nominal interest rate. Banks must also disclose the effective rate (APR/EKS), which includes processing fees, insurance and other costs — so the effective rate is always equal to or higher than the nominal one. When comparing bank offers, always compare effective rates.
Frequently asked questions
What is an annuity?
An annuity is the fixed monthly amount you pay on a loan. It consists of a principal part and an interest part; their ratio changes over the life of the loan while the total payment stays constant.
Why is my real payment different from this result?
Your bank may include fees and insurance in the payment, uses the effective rate rather than the nominal one, and rounding rules and disbursement dates also matter. This calculation is informational, not a bank offer.
How does the term affect total interest?
A longer term lowers the monthly payment but accrues interest for longer, so the loan costs more overall. A shorter term means a higher payment and less total interest.
