Compare a property’s price with its floor area, work backward from an area-based quote, or calculate how much space a budget buys. Purchase, monthly rent, and annual lease prices stay clearly separated.
Choose a calculation
Price per area divides a total purchase price or rental amount by floor area. Total price multiplies the area by a price per square foot, square meter, or square yard. Affordable area divides your budget by an area-based price. Compare properties accepts one price and area pair per line and shows each property's unit price plus a combined weighted figure.
Select the correct time basis before interpreting the result. A purchase price is a one-time amount. Rent and lease prices can be monthly or annual. Changing the basis relabels the value you entered; it does not silently multiply or divide that input. Rental outputs also show equivalent total monthly and annual amounts.
Formula
price per square foot = total price / area in square feet
total price = area × price per matching area unit
affordable area = budget / price per matching area unit
combined unit price = sum of prices / sum of areas
1 square foot = 0.09290304 square meters
Area and price units can differ. For example, you can enter a floor area in square meters with a quote per square foot. The calculator converts the area first. A larger numeric price per square meter is normal: one square meter contains about 10.7639 square feet.
Examples
A property purchase
A 300,000 purchase with 1,500 ft² costs 200 per ft², or approximately 2,152.78 per m². This is a floor-area comparison, not an appraisal.
An annual lease quote
A 1,200 ft² space quoted at 24 per ft² per year has base annual rent of 28,800, equivalent to 2,400 per month. Additional service charges, utilities, and taxes are not automatically included.
Combining two properties
A property priced at 100,000 with 1,000 ft² costs 100 per ft². Another priced at 400,000 with 2,000 ft² costs 200 per ft². Combined, 500,000 ÷ 3,000 = 166.67 per ft². Simply averaging 100 and 200 gives 150, which treats the two properties as equally sized.
Keep floor-area definitions consistent
Use the same area convention for every property in a comparison. Usable floor space, rentable area, and a listing's reported area may describe different things. A garage, balcony, shared corridor, or unfinished room may be treated differently across measurements. This calculator does not choose an appraisal or local measurement standard for you.
Use the square footage calculator to calculate areas from dimensions or combine shapes. Enter the resulting floor area here when the task is to compare price rather than measure a room. For land, a price-per-acre comparison may be more appropriate than floor-area pricing.
What the price includes
A purchase calculation does not add closing costs, mortgage interest, taxes, insurance, or renovations. A rental calculation does not add deposits, common-area charges, utilities, rent increases, or concessions. Include any costs you want to compare consistently in the price input, or use the rental property and affordability calculators for broader cash-flow planning.
For comparison mode, all lines must use the same currency, area unit, and time basis. The currency selector changes the display symbol; it is not an exchange-rate converter. Zero price is accepted for a no-cost comparison, but floor area must be positive. Finding affordable area also requires a positive budget and unit price.
