Price per square foot: Why it matters and how it's calculated

One of the easiest ways to determine a home's value is to look at the price per square foot, which helps you compare similar homes and often factors into how properties are assessed.

Learn why calculating home value using price per square foot is important, how to do so, how to compare price per square foot, and more.

What is price per square foot?

Price per square foot is a benchmark used in the real estate market to assess a home’s relative value. It's calculated by dividing a home's listing price or fair market value by its total square footage.

“Price per square foot gives buyers and sellers a simple way to compare homes without getting overwhelmed by all the details right away,” says Taylor Kovar, a certified financial professional based in Houston. “It helps you quickly see whether a home is priced in line with others in the same area – which is especially useful when you are trying to make sense of the market.”

Factors affecting a property’s price per square foot include its location, age, condition, number of rooms, lot size, upgrades, and renovations.

A high price per square foot doesn’t necessarily mean the home is overpriced, and a low price per square foot doesn’t necessarily mean the property is a steal.

Why does price per square foot matter?

Although the price per square foot doesn’t tell you everything you need to know about the value of a home for sale, it’s a good starting point when evaluating properties.

Comparing the neighborhood’s average price per square foot to the home you want to purchase can help you determine how that property measures up to similar homes in the area. Keep in mind that home values tend to be similar among comparable homes within the same neighborhood.

Calculating price per square foot

If you are ready to buy a house and want to learn how to calculate home value using price per square foot, the formula is:

List price ÷ total square footage = price per square foot

Let’s say you’re looking at a 1,500-square-foot home listed for $400,000. The price per square foot would be:

$400,000 ÷ 1,500 = $267 per square foot

How to calculate square footage

Ben Goheen, a certified residential appraiser with Metrowide Appraisals in Minneapolis, says that using a laser measurer – available from many home improvement stores – is the most accurate way to measure square footage.

“You want to measure around the perimeter of the home, separating above-grade from below-grade areas,” he says.

Keep in mind that in a home-for-sale listing, only finished, heated, and fully livable spaces count toward the square footage.

“In most places, the code says that the (ceiling) height must be at least 7 feet," says Kristin Boekhoff, CEO of Bright Door Homes in Orlando, Florida. “The space must also be finished, meaning that it has flooring, finished walls, and no exposed electrical, insulation, or studs. Also, if it is a bedroom, it has to have proper egress to count as a bedroom.”

The standard used for appraising is gross living area, which includes finished, above-grade living space, Goheen says. That means even finished basements don't count because they are below grade. Finished attics may count if at least 50% of the space has a ceiling height of at least 7 feet, and there’s a stairway to access it (not a pull-down ladder).

How to compare price per square foot

Here's an example of how price per square foot can vary.

Imagine two homes for sale in the same neighborhood. The first home is 1,500 square feet and listed for $280,000, for a price per square foot of about $187. The second home is 2,000 square feet and listed at $300,000, for a price per square foot of $150.

The more expensive home is cheaper per square foot, meaning you get more space for the price.

This is only one factor to consider when shopping for homes. The price per square foot doesn't account for the home's condition or features. The cheaper home with the higher price per square foot may have been recently remodeled or include attractive features that the other home does not.

“You can get the best comparisons when you look at homes that closely match one based on condition, age, updates, layout, and neighborhood," Kovar says. "A renovated kitchen, new roof, or open floor plan can all push the price per square foot higher – even when the homes are the same size.”

It's also important to verify what's being measured. "Different professionals may include or exclude certain spaces, which is another reason why taking a fresh measurement can be helpful,” Kovar says.

Median price per square foot

If you listed the price-per-square-foot values for an area, the median would be the value right in the middle, separating the top and bottom halves. As of January 2026, the median price per square foot in the United States is $220, according to the Federal Reserve Bank of St. Louis.

Depending on where you want to live, the price per square foot of the homes you are considering could be significantly higher or lower than this number.

For example, you might see a much higher price per square foot in expensive cities where living space is in high demand. Cases in point: The median sale price per square foot as of January 2026 is $783 in San Jose, $461 in Boston, $655 in Los Angeles, and $542 in the New York metropolitan area, versus only $260 in Salt Lake City, $207 in Chicago, $214 in Savannah, Georgia, and only $169 in Detroit.

The bottom line: Price per square foot can help you compare home values

Price per square foot is not the only number to consider when shopping for a home, but it can offer a useful indication of a home's value compared with others for sale in the area. Take the time to calculate and understand the square footage price of a home on your list before committing to a purchase, and ask questions about anything you don’t understand – especially if this number seems too good to be true.
