Calculator FAQ

Which construction calculator should I use first?

For a single trade, open that tool directly (concrete, roofing, framing, etc.). For a full remodel or new build, start with Whole Build to sequence trades in construction order, then refine each phase.

Are these calculators really free?

Yes. All 17 tools — including the Full Job Estimator — are free on the Starter plan. No account or credit card is required to calculate, save locally, print, or copy results.

Can I price jobs in other cities?

Yes. Enter the job-site ZIP to load typical regional labor and material defaults, then override any line with your real supplier and crew rates before bidding.
