Guides
Split shared-flat cost fairly
When equal shares make sense and when room size or special use should matter more.
Separate fixed and area-based cost
Internet or broadcast fees are not area-based. Room rent, exclusive use and area advantages can be distributed differently.
Formula beats gut feeling
A transparent formula prevents recurring arguments and makes later adjustments easier.
Do not forget shared rooms
Kitchen, bathroom, hallway and balcony benefit everyone and should not only be reflected through room size.
How to use this guide in practice
The guide does not replace a personal decision. It separates recurring cost, one-off cost, documents and uncertainty so a home is not only attractive but workable in daily life.
Internet or broadcast fees are not area-based. Room rent, exclusive use and area advantages can be distributed differently. Mark what comes from a source and what is only estimated. Housing offers, moving and service charges become error-prone when both are mixed mentally.
Before committing
- Note warm rent, additional costs and one-off start costs separately.
- Collect open points from viewing, contract or handover in writing.
- Carry only reliable numbers into the comparison.
Cross-check with calculators

Keep the boundary
Orientation model. Not tenancy-law advice, contract review or structural assessment. Contracts, defects, area disputes and legal deadlines need a qualified review.
