Interest rate (úroková sazba)
The price of a loan, expressed as a percentage of the amount owed per year. For a mortgage the bank sets it for the fixed-rate period according to the market price of money, LTV, income, insurance and other conditions. According to ČBA Hypomonitor, the average rate on new mortgages for August 2026 was 5.00 %, while offered rates in the Swiss Life Hypoindex stood at 5.79 % in October 2026.
Example
A difference of 1 pp on a CZK 4,000,000 loan over 25 years amounts to roughly CZK 2,300–2,400 a month. At 4.43 % from March 2026 the payment is CZK 22,075, at the August average of 5.00 % it is CZK 23,384, and at 5.80 % it is CZK 25,285. Over the full term, each percentage point means about CZK 700,000 in interest.
In practice
Individual offers in September and October 2026 sit in a band of roughly 4.7–5.8 %, depending on LTV, fixation length and insurance. An advertised “from” rate usually applies only if you meet every discount condition. Have the rate confirmed in writing in the offer; during the thinking-time period the bank cannot change it. Look at the APRC and fees as well, not just the rate.
How it differs
The APRC adds compulsory fees and insurance to the rate. A different rate, the ČNB repo rate (3.75 %), applies between the central bank and commercial banks and affects mortgages only indirectly. The interest margin is the part of the rate the bank takes above the cost of money, and that is exactly what you can negotiate.
