Spray Foam Pricing Calculator
Enter the square footage, thickness, foam type, your cost per set, and the margin you want, and this tool gives you a suggested job price and price per square foot. It handles the board-foot and set math for you.

material cost
This is a materials-based estimate: board feet × set cost, marked up to your target margin. It does not include labor, travel, equipment, or overhead, so treat the number as a floor and add your own costs. Yields vary by product and conditions. Always check against your real job data.
How the pricing math works
Every spray foam price starts with volume. The calculator multiplies your square footage by the thickness to get board feet, divides by the typical yield per set for your foam type (about 4,000 board feet for closed-cell, 16,000 for open-cell), and multiplies by your cost per set to get your material cost. Then it marks that up to the margin you set. If your material cost is $2,000 and you target a 40 percent margin, the suggested price is about $3,333.
Use your own numbers
The two inputs that make or break the estimate are your cost per set and your margin. Set cost moves with chemical prices, so put in what you are actually paying today, not a number from last year. Your margin has to cover more than foam: labor, your rig and equipment, fuel and travel, insurance, and the profit the job needs to be worth doing. This tool gives you the material floor. Your real price is that floor plus everything it takes to run the job.
Why pricing discipline matters
The fastest way to lose money in this business is to bid off a gut feel. The contractors who stay profitable price every job the same way and know their numbers cold. If you want to check your foam volume first, the board foot calculator breaks that out on its own.
Common pricing questions
How do you price a spray foam job?
Start with the material: board feet (area times depth) divided by the yield per set gives the number of sets, times your cost per set gives your material cost. Then mark that up to cover labor, overhead, and profit. This calculator does the material math and applies your target margin so you get a suggested price fast.
How much does a set of spray foam cost?
It varies by supplier, product, and the market, commonly somewhere around $1,500 to $2,200 per set. Use your own current set cost in the calculator for an accurate number, since this moves with chemical prices.
What margin should an insulation contractor use?
There is no single right answer, but many spray foam contractors target somewhere in the 35 to 50 percent range on a job once labor and overhead are covered. The right number for you depends on your costs, your market, and how much work you have. Enter a few values to see how margin changes the price.
Does this include labor?
No. This is a materials-based estimate marked up to your target margin. Labor, travel, equipment, and overhead are not included, so treat the output as a floor and add your real costs on top.
