Property Price per Square Foot and Metre Calculator

Convert a supplied price and floor area into comparable price-per-area figures. Match the area definitions before comparing properties; the ratio is not a market valuation or a construction quote.

How the calculation works

Price per unit of floor area helps compare property prices on a common size basis. Enter one total price and the corresponding measured area. The calculator expresses the same ratio per square metre and per square foot; it does not infer a property value from local transactions.

One square foot = 0.09290304 square metres exactly. Price per area = entered property price / area in the selected output unit.

  1. Define a comparable price basis

    Decide what the numerator contains before comparing listings. A price including parking, land or furnishings may need interpretation alongside a listing whose price covers only the dwelling.

  2. Convert the supplied area

    The selected unit determines how the area is expressed in both measurement systems. This allows a square-foot listing and a square-metre listing to be viewed in the same unit.

  3. Divide price by area

    The total price is divided separately by square metres and square feet. Smaller area for an unchanged price raises both ratios; changing only the display unit should describe the same underlying property.

Worked example: Square metre input

Sample inputs demonstrate the method. They are not a forecast or product offer.

The example divides €100,000 by 100 square metres, producing €1,000 per square metre. Converting that unit price with the exact area factor gives €92.90304 per square foot, displayed as €92.90.

Property price
100000
Floor area
100
Entered area unit
Square metres

Expected result

Price per square metre
€1,000.00
Price per square foot
€92.90
Worked example: Square foot input

Sample inputs demonstrate the method. They are not a forecast or product offer.

Property price
100000
Floor area
1000
Entered area unit
Square feet

Expected result

Price per square foot
€100.00
Area in square metres
92.9

Understanding your result

The outputs are monetary amounts per unit of area, not percentages. They summarise the supplied price and size but do not account for location, condition, layout, tenure or the usefulness of particular rooms.

Use the ratios as one comparison measure rather than a valuation or construction quotation. A larger property can have a lower unit price while still requiring a much larger total budget.

Questions you might have

Can I compare gross and usable floor areas?

Not directly. Use the same measurement definition across properties before comparing their prices per unit.

Choosing the right inputs

Property price
Use the price that matches your comparison: for example, asking price or agreed purchase price. Include additional purchase costs only if you intend to compare a total acquisition-cost basis across every property.
Floor area
Use a positive floor area measured on a consistent basis. Gross floor area, usable space and an external footprint are different measurements and can produce materially different price ratios.
Entered area unit
Choose the unit of the area you actually entered. The engine converts the area using one square foot equal to exactly 0.09290304 square metres; it does not change the total property price.

Common mistakes to avoid

  • Do not enter square feet while leaving the selector on square metres.
  • Do not compare a gross-area denominator with a usable-area denominator without recognising the difference.

Assumptions to check

  • Use comparable floor-area definitions; this ratio is not a market valuation or construction quote.
