For example, the impact on the average monthly new mortgage payment of approximately 26,900 CZK, with a median of 21,6,000 CZK. The combination of a rise in interest rates and a higher average mortgage amount in October 2026, compared to the average values from 2025, increased the average monthly payment on a newly issued mortgage by 4,2,000 CZK.
The rise in mortgage rates by nearly 0.7 percentage points from their average of 4.58% in 2025 resulted, for an average mortgage size with its typical repayment term of nearly 27 years, an increase in the monthly payment of just under -1,800 CZK to approximately 26,900 CZK. Compared to the average mortgage rate of 5.07% in 2024, the change due to the interest rate amounted to just under -500 CZK for a mortgage at its current average value.
However, the current average mortgage amount was 11% higher than its average amount in 2025, which contributes to an increase in the monthly payment of 2,600.
The impact of the interest rate on expiring fixed-rate periods varies in terms of mortgage trends, depending on the year in which the interest rate was fixed. Illustrative examples? Compared to the average 2.33% mortgage interest rate for new mortgages in 2021, the current mortgage rate for refinancing of 5.17% —when the loan term is shortened—increases the monthly payments on an average mortgage by nearly 4,100 CZK, or about 7.8% of the current average gross wage. However, that wage has increased by 35% compared to the end of 2021. Conversely, the current interest rate would reduce the monthly payment on a 2023 mortgage with an interest rate of 5.82% by about 1,100 korunas. In 2027, mortgage refinancing from 2024 with an interest rate of 5.11% will dominate, with the current interest rate level representing an increase of approximately 192 koruna.
