Buying a home with a mortgage is a commitment for 20–35 years. That is why choosing the bank and the offer requires particular care. Even small differences in the interest rate can mean tens of thousands of zlotys difference in the total cost.
The mortgage interest rate in Poland is usually made up of two components: WIBOR (a variable reference rate set by the interbank market) and the bank's margin (fixed for the life of the loan). In 2026, WIBOR 3M is around 5.8%, so even a margin difference of 0.2 percentage points has a significant impact on the total cost.
Creditworthiness depends on income, existing obligations, number of dependants and credit history. Banks typically allow a maximum total monthly instalment of 40–50% of net income. A higher own contribution (20% instead of 10%) lowers the margin.
