Cost Per Square Foot Formula
The cost per square foot calculation compares a total cost to the total area covered by that cost. The calculator can solve for total cost, total area, or cost per square foot when you enter the other two values.
Cost\ per\ ft^2 = Total\ Cost / Total\ Area
Total\ Cost = Cost\ per\ ft^2 * Total\ Area
Total\ Area = Total\ Cost / Cost\ per\ ft^2
When square meters are used, the calculator converts area using:
1\ m^2 = 10.7639\ ft^2
- Total Cost is the full price paid or estimated, in dollars.
- Total Area is the size of the space or surface, entered in square feet or square meters.
- Cost per ft² is the price for each square foot of area.
- Cost per m² is the price for each square meter of area.
If you leave Total Cost empty, the calculator multiplies the area by the cost per square foot. If you leave Total Area empty, it divides the total cost by the cost per square foot. If you leave Cost per square foot empty, it divides the total cost by the area.
Common Cost Per Square Foot Benchmarks
Actual prices vary by location, materials, labor, and project scope. These ranges are useful for checking whether a result looks reasonable.
| Use Case | Typical Cost Range | Notes |
|---|---|---|
| Basic flooring material | $2 to $15 per ft² | Material only, not always including installation. |
| Interior painting | $1 to $6 per ft² | May be based on wall area or floor area, depending on the quote. |
| Residential construction | $150 to $400+ per ft² | Depends heavily on region, design, finishes, and labor costs. |
| Commercial lease comparison | Varies widely | Often quoted annually, such as $30 per ft² per year. |
Square Foot and Square Meter Conversion
| Conversion | Value |
|---|---|
| 1 square meter | 10.7639 square feet |
| 1 square foot | 0.092903 square meters |
| $/m² to $/ft² | Divide by 10.7639 |
| $/ft² to $/m² | Multiply by 10.7639 |
Example Calculations
Example 1: Find cost per square foot
You have a total cost of $12,000 and an area of 1,500 ft².
Cost\ per\ ft^2 = 12000 / 1500 = 8
The cost is $8.00 per ft².
Example 2: Find total cost
You have an area of 80 m² and a cost of $25 per ft². First convert the area to square feet.
80\ m^2 * 10.7639 = 861.112\ ft^2
Total\ Cost = 25 * 861.112 = 21527.80
The total cost is $21,527.80.
FAQ
How do you calculate cost per square foot?
Divide the total cost by the total area in square feet. For example, if a project costs $5,000 and covers 400 ft², the cost per square foot is $5,000 ÷ 400 = $12.50 per ft².
Can I use square meters instead of square feet?
Yes. If you enter area in square meters, the calculator converts it to square feet using 1 m² = 10.7639 ft². If you choose $/m² for the cost field, the calculator converts between $/m² and $/ft² as needed.
What should be included in total cost?
Use the full cost that matches what you want to measure. For a flooring job, that might include materials, labor, removal, and fees. For a home purchase, it might be only the purchase price. Keep the definition consistent when comparing multiple results.
