Home Value Per Square Foot Calculator
Calculate home value per square foot to compare properties.
Analyze price per sq ft for buying, selling, or estimating home value.
Price per square foot (or price per square metre) is one of the most useful metrics in real estate. It allows you to compare properties of different sizes on an equal footing, identify overpriced listings, and estimate the value of a home based on comparable sales in the same neighborhood.
The Formula
Price per square foot = Total home price ÷ Living area in square feet
Or in metric: Price per square metre = Total home price ÷ Living area in square metres
What to Include in “Living Area”
- Include: Interior living space, bedrooms, bathrooms, kitchen, living rooms, finished basement
- Exclude: Unfinished basement, garage, attic (unless finished and permitted), outdoor spaces
This is typically the “above grade living area” on a property listing. Using the correct figure is critical — comparing finished vs unfinished space gives misleading results.

When This Metric Is Useful
- Comparing two similar properties in the same neighborhood
- Checking if a listing is over- or under-priced
- Estimating renovation ROI (if an addition increases sq footage, what value does it add?)
- Tracking neighborhood price trends over time
Limitations
Price per square foot doesn’t account for lot size, views, finishes, age, school district, or condition. Two homes with the same sq footage can vary dramatically in value. Always use it alongside other comparables, not in isolation.
