Price Per Square Foot Calculator
Calculate and compare price per square foot for up to 4 properties side by side. Include closing costs, compare against area median, and identify the best value property — free, private, and instant.
How Price Per Square Foot Is Calculated
Price per square foot is the most straightforward metric in real estate valuation. Divide the total purchase price by the property's livable square footage to get a single comparable number. For example, a home listed at $350,000 with 1,800 sqft yields $194.44 per sqft. When closing costs are factored in — typically 2-5% of the purchase price according to the Consumer Financial Protection Bureau — the effective cost per sqft rises, giving you a more accurate picture of your true investment per unit of space.
This calculator uses the formula: Price per sqft = Purchase Price / Total Square Footage. The all-in version adds closing costs to the numerator. Both figures matter: the base rate helps you compare listings, while the all-in rate reflects your actual out-of-pocket cost per square foot of living space. Last updated: May 2026.
Using Price Per Square Foot for Property Comparison
Comparing properties by price per square foot normalizes size differences so you can evaluate value on equal terms. A $500,000 home at 2,500 sqft ($200/sqft) may represent better value than a $300,000 home at 1,200 sqft ($250/sqft), even though the second property has a lower sticker price. According to the U.S. Census Bureau's Annual Characteristics of New Housing survey, the median price per square foot for new construction in the United States was approximately $171 in 2024, though this varies significantly by region.
The area median comparison feature in this calculator highlights whether each property trades above or below local norms. Properties priced 10-20% below the area median may indicate value opportunities — or they may reflect condition issues, location disadvantages, or needed renovations. Realtor.com's methodology notes that price per square foot is most reliable when comparing similar property types (single-family to single-family, condo to condo) in the same neighborhood or submarket.
Limitations of Price Per Square Foot Analysis
While price per square foot is useful for quick screening, it has important limitations. It does not account for lot size, condition, age, finishes, layout efficiency, or location premiums within a neighborhood. A renovated kitchen and updated bathrooms can justify a 15-30% premium per sqft over comparable unrenovated properties. Likewise, corner lots, views, and proximity to amenities all affect value independently of interior square footage.
Use price per sqft as one data point alongside cap rate, cash-on-cash return, gross rent multiplier, and comparable sales analysis. For investment properties, revenue per square foot (annual rent divided by sqft) provides a complementary metric that connects physical space to income potential. Always verify square footage from official sources — county assessor records or a licensed appraisal — since listing sqft can be inaccurate by 5-10% according to the National Association of Realtors.
