How to Split Rent Fairly Between Flatmates in Poland

Sharing an apartment in Poland is one of the smartest financial decisions you can make, but dividing rent fairly is crucial for keeping the peace among flatmates. In cities like Warsaw, Krakow, and Wroclaw, shared apartments often have rooms of different sizes, varying access to natural light, or private balconies — all of which should factor into who pays what.

The most common approach in Polish flatshares is a simple equal split, but this only works well when rooms are roughly the same size. When one flatmate has a 16 m2 master bedroom and another has a 9 m2 box room, proportional splitting by square meter is far more equitable. Some flatmates also adjust for income differences, which works well in mixed-income households or when one person is a student and another is working full-time.

Beyond rent, remember to discuss how to handle czynsz administracyjny, utilities (media), internet, and shared supplies. Many successful flatshares in Poland set up a shared bank account or use Splitwise to track expenses. Getting the financial arrangement right from day one prevents the most common source of flatmate conflict.

• Measure each room in square meters and use proportional splitting if sizes differ by more than 20%.
• Split shared area costs (kitchen, bathroom, living room) equally, then add proportional private room costs.
• Set up a shared payment method or app like Splitwise to track utilities and shared groceries.
• Document your rent split agreement in writing — include it in your flatmate agreement (umowa wspollokatora).
• Review the split every 6 months, especially if flatmates or utility costs change.
