How does this spray foam cost calculator work out your number?
It multiplies three things: your square footage, the installed depth for that space, and the rate for the foam you picked. Spray foam is sold by the board foot, and one board foot is one square foot covered one inch thick. Cover 1,000 square feet at three inches and you bought 3,000 board feet.
The rates behind the tool are $0.45 to $0.75 per board foot for open cell and $1.00 to $1.50 for closed cell, installed. So a 1,000 square foot attic deck at six inches of open cell is 6,000 board feet, which prices at $2,700 to $4,500. The same deck in closed cell at three inches is 3,000 board feet, or $3,000 to $4,500.
Depths are not guesses. The calculator uses six inches of open cell or three inches of closed cell on an attic deck, 3.5 inches or two inches in walls, and three inches or two to three inches in a crawl space. Those match what gets installed here, and results round to the nearest $50 so nobody mistakes an estimate for a quote.
What changes the real quote once someone looks at the job?
Access is the biggest one. A walk-in basement is cheap to reach. A 30 inch crawl hatch behind a water heater can add 15% to 30% to the same square footage because of hose runs and setup time.
Prep comes next. Masking off finished rooms and covering ductwork runs $150 to $600 on an occupied Greeley house and close to nothing on open framing in a new build. Removal of old material is separate again, at $1.00 to $2.00 per square foot.
Then there are the items that belong to other trades. Knob and tube wiring, a bath fan venting into the attic, or an active roof leak all get fixed before foam goes on. And winter work in an unheated shop may need temporary heat at $100 to $300 a day, because foam that cures cold shrinks and pulls away from the framing.

When is closed cell worth the extra money in Colorado?
When you need something besides R-value. Closed cell brings a built-in vapor barrier and real structural rigidity, and those matter in specific Weld County situations rather than everywhere.
Use it under a metal roof on a pole barn or shop, where a single inch at $1.00 to $1.50 per square foot puts the steel above the dew point and ends the winter condensation drip. Use it in a crawl space, on basement rim joists, and in any rafter or stud bay too shallow to hold six inches of open cell.
Skip it on a big open attic deck with deep rafters, where open cell buys the same R-value for less. Skip it entirely if the attic is vented, empty, and the only complaint is a cold bedroom, because blown-in at $1.00 to $2.80 per square foot solves that for a third of the price.
Both foams qualify for the federal 25C credit, which returns 30% of the project cost up to $1,200 a year. The rules are on the IRS 25C credit page.

Questions about the spray foam calculator
How accurate is this spray foam cost calculator?
It is accurate for the material and labor, which is most of any spray foam bill. It runs on installed rates of $0.45 to $0.75 per board foot for open cell and $1.00 to $1.50 for closed cell, the same ranges Northern Colorado crews quote from.
What it cannot see is your access, your prep, and whether old insulation has to come out first. Treat the output as a budget range rather than a bid.
What depth does the calculator assume?
Six inches of open cell or three inches of closed cell on an attic deck, 3.5 inches or two inches in walls, and three inches or two to three inches in a crawl space.
Those are the depths most jobs in Greeley and Weld County actually get installed at. Change the square footage to model a partial area at the same depth.
Why does closed cell cost so much more in the calculator?
Closed cell is roughly twice the price per board foot, but it delivers R-6.5 to R-7 per inch against R-3.5 to R-3.7 for open cell, so it needs about half the inches. On an attic deck the two options usually finish within a few hundred dollars of each other. The extra money buys a vapor barrier and rigidity, not just R-value.
Does the calculator include removing old insulation?
No. Removal is a separate line at $1.00 to $2.00 per square foot, plus $200 to $600 if the space needs sanitizing after rodents. On a 1,000 square foot attic that is another $1,000 to $2,000 on top of whatever the calculator shows. Add it yourself if the existing material is wet, matted, or contaminated.
