Contractor Calculator

Price the job right, on the tailgate, before the customer changes their mind.

Contractor Calculator puts your takeoffs and your quote in one place. Run the numbers for concrete, framing, drywall or paint, then carry the quantity straight onto the estimate as a line item — no scribbling on a scrap of drywall, no retyping into a spreadsheet at night.

TAKEOFF CALCULATORS
- Concrete: slabs, footings, and columns — cubic yards or 60/80 lb bags, with waste built in
- Framing: studs and plates for a wall run, 16" or 24" on center
- Roofing: squares and bundles, adjusted for pitch
- Decking, board feet, drywall, paint, flooring, tile, gravel, and fence
- Results update as you type — watch the yardage move while you change a dimension
- Feet and inches the way you read the tape: 12' 6 1/2" works everywhere

ESTIMATES THAT PRICE THE WHOLE JOB
- Material, labor, and flat-charge line items
- One markup for the job, with the margin it really yields shown beside it
- Sales tax applied only to taxable lines — set your state and county rate once
- Quote, cost, profit, and margin — always in view
- Track every job from Draft to Sent, Won, or Lost

MARKUP IS NOT MARGIN
Marking up a $1,000 job by 20% bills $1,200 — but keeps you a 16.7% margin, not 20%. That gap is where contractors quietly lose a season's profit. This app never lets the two get confused: change either number and see the other move, so the job makes the money you meant it to.

EVERY CHANGE, AND A WAY TO TAKE IT BACK
Every edit is recorded — what changed, when, and on which device. Fat-fingered a price? Deleted the wrong line? Undo it from History, even days later.

BUILT FOR THE JOB SITE
- Money is exact to the cent — totals a customer can check on their own calculator
- Works completely offline; your numbers stay on your phone
- Light theme readable in full sun, dark theme for the early starts
- No account, no sign-up

GREAT FOR
General contractors, concrete and flatwork crews, framers, roofers, painters, drywall and flooring installers, deck and fence builders, remodelers, handymen, and anyone bidding side work.

From first measurement to final price — measure it, price it, send it, win it.
