How to Calculate Price Per Square Foot: The Ultimate Guide

Looking at a property listing and feeling completely overwhelmed by the sticker price is normal. We've all been there. You see a $400,000 condo and a $400,000 house and wonder how on earth they cost the same amount of money. The problem with raw prices is they are designed to trigger emotion, not logic.

The solution is to standardize the cost. By learning how to calculate price per square foot, you put every property on a single, level playing field. The math is brutal, simple, and undeniable.

The Core Formula

You don't need a math degree for this. To calculate the price per square foot, you only need the total price and the total livable square footage.

Total Price ÷ Square Footage = Price Per Square Foot

If you are looking at a $350,000 home that is 1,500 square feet, the math is: $350,000 ÷ 1,500 = $233.33 per square foot.

Running the Math in Reverse

You can also use this formula to figure out how much house you can afford or what you should list your house for.

Price Per Square Foot × Square Footage = Total Price

If you know the median price per square foot in your neighborhood is $200, and your house is 2,000 square feet, your estimated listing price should be around $400,000.

How to Handle Rentals

This metric isn't just for buying houses. If you are hunting for an apartment, you can calculate the monthly rent per square foot to see which unit gives you more breathing room.

Monthly Rent ÷ Square Footage = Rent Per Square Foot

A $2,000/month apartment that is 800 square feet costs $2.50 per square foot per month. Compare that against a $2,200/month apartment that is 1,000 square feet ($2.20/sq ft), and you instantly know the more expensive apartment actually offers better value for space.

For commercial properties, the math is slightly different. Check out our commercial vs residential guide to learn about Rentable Square Footage.
