Formula and method
A property priced at 300,000 with 100 m² of floor space costs 3,000 per m². Two more property sections let you compare like-for-like prices and areas.
Price per area = property price or rent ÷ floor area

Assumptions and limitations
- Each floor area must be positive. Choose matching area definitions, such as internal usable space, when comparing properties.
- Compare purchase prices with purchase prices or rents covering the same period. This does not adjust for location, condition, lease terms, taxes or shared areas.
- A unit price is an arithmetic comparison, not a valuation. Currency conversions use the captured reference table shown on the page rather than a live exchange quote.
Common questions
Can I compare square feet with square meters?
Yes. Each property has its own area-unit selection and its output has an area denominator. Display all unit prices in the same denominator before comparing them.
How do I reveal the third property?
Enable the second-property comparison, then enable the third. Each section computes independently from that property’s price and area.
