Price Per Square Foot: Why It Matters And How It’s Calculated

Price per unit is a concept many people deal with on a regular basis, whether they realize it or not. If you can buy a six-pack of paper towels for $5, or an 18-pack for $14, which one is the better deal?

Of course, comparing homes is a little different than comparing multipacks of consumer goods. Understanding a home’s price per square foot – and what you can learn from that number – can be a bit more complex. Here’s what you should know about the price per square foot of a property.

What Is Price Per Square Foot?

Price per square foot is a metric used in the real estate market to evaluate a home’s value. A lot of factors go into determining the price per square foot of a property. These factors include 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 always mean the home is a steal.

How Big Is A Square Foot?

“Square” measurements are equal to the length times the width of a space.

One foot is equal to 12 inches. So, if you have a space that’s 12 inches in length and 12 inches in width, it equals 1 square foot – or 144 square inches.

How To Calculate Price Per Square Foot

A home’s price per square foot is equal to the listing price divided by the home’s total square footage. For example, if a 1,000-square-foot home is listed for $200,000, the price per square foot is $200:

200,000 ÷ 1,000 = 200

Many online listing sites include the price per square foot in their listings, so you may not even have to worry about calculating this number.

How To Determine The Average Price Per Square Foot In A Neighborhood

You can calculate the average price per square foot in a neighborhood by taking the cost per square foot of a certain number of comparable homes, adding those costs up and dividing the total by the number of homes in the area.

You might be better off focusing on the median price per square foot, which is the middle value of the price per square foot for comparable homes in the neighborhood. We’ll go over median price per square foot later on in the article.

Why Does Price Per Square Foot Matter?

What can the price per square foot tell buyers and sellers about a home’s price and value? While this number doesn’t provide much useful information on its own, price per square foot should be used as a starting point for further investigation.

Home values tend to be similar among comparable homes within the same neighborhood. Comparing the neighborhood’s average price per square foot to the home you want to buy can give you an idea of how your prospective home measures up to similar homes in the area.

For example, if you’re thinking of buying a home with a higher price per square foot than its very similar next-door neighbor, you might want to ask your real estate agent why that’s the case. It could be that the home you’re looking at has upgrades or features the other home doesn’t.

Price Per Square Foot Example

Let’s take a look at an example of how price per square foot can vary.

Alex and Taylor are next-door neighbors, and they’re both selling their homes.

• Alex is selling their 1,500 square-foot home for $280,000 with a price per square foot of nearly $187.
• Taylor is selling their 2,000 square-foot home for $300,000 with a price per square foot of $150.

Even though Taylor’s home is more expensive overall, isn’t their home the better deal because you’re getting more space for less money? Not necessarily. Does this mean that Alex’s home is overpriced? Again, not necessarily.

Consider this: Alex, knowing they’d be selling soon, made some updates to their home to boost its value. Taylor didn’t make any improvements to their home, so the interior shows a little wear and tear and several of the home’s main systems will likely need replacing in a few years. In this case, Alex’s home might be the more attractive option for home buyers.

Median Price Per Square Foot

The current median price per square foot in the U.S. is around $233, according to May 2024 data from the Federal Reserve Bank of St. Louis. Depending on where you’re aiming to buy a home, the price per square foot of the homes you look at might be significantly higher or lower.

For example, you might see a much higher price per square foot in expensive cities where living space is in high demand. Case in point, it’s not uncommon in New York City to see a price per square foot that’s above $1,000.

What’s The Difference Between Median And Average Price Per Square Foot?

Median refers to the middle value in a data set. When talking about median price per square foot, take the price per square foot on a number of comps and look at the number right in the middle – from the house with the lowest price per square foot to the house with the highest. This will give you the median price per square foot for similar homes in that particular area.

On the other hand, the average price per square foot is found by adding up the price per square foot of all the comparables and dividing that number by the number of homes being compared. Unlike median price per square foot, the average price per square foot can be skewed if some homes in the group of comparables have a price per square foot that’s well above or well below what’s typical for that type of house in that area.

The Bottom Line: Price Per Square Foot Can Help You Compare Home Values

Price per square foot on its own gives you a fairly limited understanding of a home’s value. However, it can give you an idea of the questions to ask about a home you might purchase.

Work closely with your real estate agent to get the full picture of what your prospective home has to offer. Your agent can also point out any red flags they see concerning the quality or condition of the home.
