Monthly payment (měsíční splátka)
The amount the borrower pays the bank every month. With a mortgage it is almost always an annuity: the payment stays the same during the fixed-rate period and is made up of interest and principal repayment. When the fixation ends, the bank recalculates it from the new rate and the remaining debt. The average new mortgage in August 2026 was CZK 4.59 m, with an illustrative payment of CZK 25,888.
Example
A CZK 4,000,000 loan over 25 years at 5.00 % means a payment of CZK 23,384. Of the first payment, CZK 16,667 goes on interest and only CZK 6,717 on principal. The same amount over 30 years works out at CZK 21,473, while at 5.80 % over 25 years it is already CZK 25,285.
In practice
The bank checks whether you can carry the payment. Its usual internal ceiling is 45 % of net income for all payments together, or 50 % for applicants under 36. Before your fixation ends, work out the payment at a higher rate too, so the recalculation does not catch you off guard. Many borrowers stretch the term to 30 years for a lower payment and then never shorten it with extra repayments.
How it differs
An annuity is a repayment method with a constant payment; the monthly payment is the actual amount in koruna. Principal repayment is only the part of the payment that reduces the debt. Unlike an extra repayment, the monthly payment is regular and set by the contract. An extra repayment can lower it, though, if you ask the bank to.
