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

When buying a home, knowing how far your budget extends is vital to a productive home search, and this is where understanding the price per square foot can help.

Price per square foot helps you see what you're paying relative to a home's size, making it much easier to compare similar properties. Learning how to calculate this simple metric builds confidence in understanding the complete home value of a property.

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 list 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,” said 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 cost per square foot matter?

While similar homes in similar neighborhoods may offer comparable prices, calculating the cost per square foot helps buyers understand the breakdown of price related to the size of the home. Even a small difference may lead to a buyer perceiving the home as more affordable. To learn how a home compares to others, it’s a good idea to look at local real estate comps to make sure you’re getting a fair deal.

Calculating price per square foot

The equation necessary to calculate price per square foot is fairly simple:

  List price / the home’s total square footage =  price per square foot

Let’s look at an example. Suppose a home costs $350,000 and has 1,500 square feet of livable space. Here’s how you’d calculate the price per square foot: 

350,000 / 1,500 = $233.33 per square foot

Learning how to calculate price per square foot is an essential skill as you discover how to buy a house tailored to your financial goals.

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 said.

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," said 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 said. That means even finished basements don't often 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, a price of about $187 per square foot. The second home is 2,000 square feet and listed at $300,000, a price of $150 per square foot.

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 said. "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 said.

Median price per square foot

Median means in the middle, so the median price per square foot would be the number that falls in the middle of a specific list of homes on the market. According to the Federal Reserve Bank of St. Louis, the median price per square foot of homes in the U.S. as of May 2026 is $228.

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.

As of May 2026, the median price per square foot in Los Angeles County is $640, while in Seattle/Tacoma/Bellevue, Washington, it's $452 . Over on the East Coast in Miami-Dade County, Florida, it's $465. Depending on where a house is located, the price per square foot can be wildly different.

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

Understanding how to calculate cost per square foot can help buyers maximize their budget and get the most value of their future home. Keep in mind that different areas may have higher or lower costs depending on local variables, like a renowned school district, so it’s important to learn how to compare homes effectively
