Spray Foam Cost Calculator
Get an instant, real-number estimate for your project based on square footage and foam type.
Use the calculator below to get a real, board-foot-based cost estimate for your project. It's a starting point based on typical installed pricing — not a final quote — but it's built on the same math a real estimate uses, not a guess.
How This Calculator Works
The estimate is based on your selected foam type's typical installed price per board foot, multiplied by your area and target thickness. Open-cell and closed-cell use different pricing ranges and typical thickness targets, reflecting how each is actually specified in the field.
What This Estimate Doesn't Include
This calculator doesn't account for job accessibility, substrate prep, regional labor cost differences, or minimum job charges — all of which affect a real quote. Treat the result as a realistic starting range to plan around, not a number to hold a contractor to sight unseen.
Key Takeaways
- The calculator uses real board-foot pricing math, not a flat guess.
- Open-cell and closed-cell use different price ranges and typical thickness targets.
- The estimate doesn't account for accessibility, prep work, or regional cost differences — get a real quote for an exact number.
