In short
This is not a ranking and not an offer. We compare facts from the banks’ public documents and representative examples, recalculated for the same amounts. The bank sets your final rate and loan amount after assessing your application.
How much one person on PLN 7,000 net could borrow
A single buyer has one income and a one-person household, so the rate and the loan term decide the amount. We calculated it for one person with no other loans, using the rate from each bank’s representative example and the longest term the bank states in its documents. Alior Bank comes out higher, thanks to a lower rate in its example (6.95% vs 6.97%) and a longer term (35 years).
| Rate type | Alior Bank: rate, term, amount | Erste Bank Polska: rate, term, amount | Difference |
|---|---|---|---|
| Fixed rate | 6.95% fixed for 5 yrs, up to 35 yrsPLN 440,000–550,000 | 6.97% fixed for 5 yrs, up to 30 yrsPLN 422,000–527,000 | PLN 23,000 |
Assumptions and sources. Details
An illustration, not a bank decision: the lower amount assumes instalments up to 40% of income, the higher one 50%. Each bank uses its own living costs and limits, so its result may differ.
Saving the deposit on one salary
Both banks ask for a deposit from 10% of the property value, which is PLN 45,000 on a flat at PLN 450,000. A single buyer who owns no home can also buy without a deposit under the family housing loan (rodzinny kredyt mieszkaniowy), which does not require children but is for Polish citizens (a foreigner only together with a Polish partner): both banks describe it.

Check in the information sheet how much the margin rises if you stop using the bank’s account or insurance.
Loan term
Alior Bank lends over up to 35 years, Erste Bank Polska over 30. On one salary, a longer term often decides whether your creditworthiness is enough: at 6.95% the instalment on PLN 400,000 is PLN 2,541 over 35 years and PLN 2,648 over 30. A longer term also means more interest overall, so plan overpayments.
