Takeoff calculators for every trade.
Sixteen free calculators that turn quantities you already know into material lists, pipe and wire sizes, and ROI numbers — and export them as proper Excel takeoff templates with live formulas. No sign-up.

→Wire size calculator
Load amps + length → minimum AWG by ampacity with voltage-drop upsize.
→Voltage drop calculator
Wire, length and load → VD volts and %, against 3%/5% guidance.
→Water pipe sizing calculator
Fixture units or GPM → pipe size for copper, PEX and CPVC.
→Takeoff ROI calculator
Your bid volume → hours and dollars manual takeoffs cost you each month.
→Calculators price what you can count. Pilars reads what you can’t.
Every tool on this page works from quantities you type in — which means quantities you already measured. The expensive mistakes live in the drawings: the wall-type legend, the finish schedule, the panel schedule, the riser diagram, the hardware sets buried in the spec book. Pilars AI takeoff reads the full plan set and returns bid-grade quantities by assembly — $100 per trade, per plan, unlimited projects.
Questions contractors actually ask
Are these takeoff calculators really free?
Yes — all sixteen, no sign-up. Enter your quantities, see the material list instantly, download the Excel. Pilars makes money on AI plan takeoffs ($100 per trade), not on calculators.
What do the Excel downloads contain?
A real .xlsx workbook with an input sheet and a materials sheet. The cells carry live Excel formulas, so you can change quantities, spacing or waste factors inside Excel and everything recalculates. Blank reusable templates are included too.
Which trades are covered?
Drywall, HVAC, electrical, plumbing, concrete, rebar, door hardware and windows — each with its own trade-specific factors, all documented on the page.
How accurate are calculator-based takeoffs?
They use standard industry estimating factors — good for budgets and quick material orders. For bid-grade takeoffs from actual plans, Pilars AI reads the full set for $100 per trade.
