What is price per square foot?

When comparing the cost of property purchases or rentals, price per square foot can often prove a useful metric to aid your decision-making process. You'll commonly find it quoted by real estate agents, mortgage loan officers and others in the property and construction business.

As a consumer, the price per square foot serves to help you gauge how expensive a property might be to buy or rent in comparison with other similar properties. And similarity is the important point here, because looking only at the price per square foot of living space won't necessarily give you an accurate indication of value. Indeed, when comparing properties, other factors should come into consideration, including the location, the type of property, the build quality, style, condition and any additional features (a swimming pool, for example).

What is the average price per square foot?

It goes without saying that the average price per square foot of property will vary based upon location, as well as many other factors that affect desirability and valuation. As an example, a square foot of floor space in residential California might be valued at over $250, compared to a similar square foot of floor space in Iowa at $100.

How to calculate the price per square foot

Price per sq. ft formula for property purchases

Price per square foot = price ÷ floor space in ft²

Price per sq. ft formula for rental properties

Rent per square foot = monthly rent ÷ floor space in ft²

Calculating the average price per square foot

If you want to get an overview of neighborhood values, one good way to do this is by working out the average price per square foot in that given area. To do this, simply add together the square foot cost of each property in the neighbourhood and then divide it by the number of properties. Let's say, for example, that there are 4 properties sold on Pages Avenue, all of a similar size with one in less-good condition:

  • Property 1 sold at $250 per ft²
  • Property 2 sold at $230 per ft²
  • Property 3 sold at $220 per ft²
  • Property 4 sold at $180 per ft²

Our average price per square foot for Pages Avenue stands at (250+230+220+180) ÷ 4 = $220.
