When to use it
Use it when warm or base rent only becomes comparable relative to plausible area.
Area and layout
Calculate warm rent, base rent and area into comparable cost per square meter.
More context
Use it when warm or base rent only becomes comparable relative to plausible area.
Rent and area create price per square metre; balcony or slope shares should be plausible first.
A low square-metre price helps little if the area is hard to use.
Then compare two offers with commute and start cost.
Compare apartment offersBoth can help: base rent for listing comparison, warm rent for real monthly load.
Comparison value, not a statement about local market rent.
Then compare two offers with commute and start cost.
Decision help
Use it when warm or base rent only becomes comparable relative to plausible area. The important part is not to treat the output as one winning number. It is a plausibility value for viewing, acceptance, moving or household planning.
Rent and area create price per square metre; balcony or slope shares should be plausible first. If an input is estimated, keep it visible. That way you later know which figure came from a contract, offer, measuring tape or bill and which was only a provisional assumption.
A low square-metre price helps little if the area is hard to use.
Then compare two offers with commute and start cost. The next useful cross-check is Compare apartment offers, because it tests the same housing decision from a second angle.
Calculation path
Cost per m² = monthly cost / area
Comparison value, not a statement about local market rent.
Base rent per m² and warm rent per m² answer different questions.
