WIBOR is falling, and mortgage installments with it! Check how current rates affect your wallet and what lies ahead for borrowers in the coming months.
What is WIBOR and why does it matter?
WIBOR (Warsaw Interbank Offered Rate) is the reference interest rate at which banks lend money to each other on the Polish market. Most mortgage loans in Poland are priced based on it. The lower the WIBOR, the lower the loan installment – and vice versa.
Current WIBOR rates – April 2025
At the end of April 2025, WIBOR had clearly dropped compared with the beginning of the year. Here are the latest values:
Current WIBOR rates
| WIBOR type | Rate (%) | Update date |
|---|---|---|
| WIBOR 1M | 5.68 | 24.04.2025 |
| WIBOR 3M | 5.45 | 24.04.2025 |
| WIBOR 6M | 5.14 | 24.04.2025 |
For comparison, back in March WIBOR 3M stood at 5.85-5.86%. The declines are therefore noticeable and translate directly into mortgage installments.
How does a change in WIBOR affect mortgage installments?
Quick calculator: how much can you save?
A fall in WIBOR means lower interest on variable-rate loans. For example:
- A PLN 400,000 loan over 30 years, variable interest rate.
- Over the past half-year, the installment was approx. PLN 2,893.
- After the update (WIBOR 6M dropped to 5.14%), the installment will fall to approx. PLN 2,753, i.e. PLN 140 less per month.
The bigger the loan, the bigger the difference. With a PLN 700,000 loan, the installment may drop by as much as PLN 245. It is worth remembering that the interest rate is updated every 3 or 6 months, depending on the type of indicator (WIBOR 3M or 6M).
Mortgages in 2025 – what do they cost and what does the market look like?
Despite high interest rates and the end of the “Safe Loan 2%” (“Bezpieczny Kredyt 2%”) programme, Poles continue to willingly take out mortgages. In March 2025, banks granted housing loans totalling PLN 7.68 billion. The average value of a new loan was PLN 428.2 thousand and was 3% higher than a year earlier.
RRSO and the total cost of the loan
- The annual percentage rate of charge (RRSO) for variable-rate loans currently stands at approx. 8-10%, and for loans with a periodically fixed rate at 7.5-8.5%.
- An example loan of PLN 400,000 over 25 years means repaying nearly PLN 900,000 at current rates.
What next for WIBOR and loan installments?
Experts expect that in the coming months WIBOR rates may keep falling if the National Bank of Poland (NBP) decides to cut interest rates. This is good news for borrowers – lower WIBOR means lower installments, and therefore real relief for household budgets.
Summary – what should a borrower do?
- Check when the interest rate on your loan will next be updated.
- Consider overpaying your loan if you can – you will reduce the principal and interest faster.
- Monitor WIBOR rates – every change may affect your installment.
It is worth staying up to date, because in 2025 changes in the mortgage market may bring real savings for many families.
