Section 02 · How it works

Real numbers, with the math shown.

Every estimate is itemized: materials, labor, fees, overhead. You can see exactly which assumptions drive the total.

01

Pick a calculator

Roofing, siding, concrete, framing, drywall, flooring — 11 project types in active development.

02

Enter your project

Dimensions, material, region. We pre-fill sensible defaults so you can ballpark in 30 seconds.

03

See itemized output

Materials, labor, tear-off, disposal, permits, overhead — all broken out separately.

04

Compare to bids

Download a PDF or send it to contractors. Bids more than ±20% off the estimate are worth a second look.

Section 03 · Methodology

Where our numbers come from.

We don't pull prices out of a hat. Every calculator is rebuilt twice a year from published 2026 cost guides, with the source list visible inside each estimate.

  • Independent review. Every calculator is reviewed by at least one licensed contractor in that trade before it ships — 5 licensed pros across the trades we cover.
  • Aggregated pricing. Material and labor rates come from HomeGuide, RoofingCalculator.com, Modernize, Homewyse, Fixr, Angi, and This Old House's annual homeowner survey.
  • Regional multipliers. 0.88–1.45 ranges approximate the RSMeans City Cost Index, applied to labor only.
  • Transparent overhead. 15% contractor overhead (midpoint of the 13–22% industry range) is shown as a separate line item, not buried in labor.

FAQ

Are these estimates or quotes?

Estimates. They reflect typical 2026 prices for a typical project in a given region. Real quotes come from a licensed contractor inspecting your specific site — use our estimate as a sanity check, not a bid.

How accurate are they?

For well-defined projects (replacing existing materials with industry-standard alternatives), our estimates fall within roughly ±10% of the median of 3 contractor bids — with a typical band of ±8–12%. Larger structural work has more variance.

Why do they show a range?

Even within the same region, contractor pricing varies ±20% based on backlog, crew size, and overhead structure. The low–high range reflects that real-world spread.

Do I need to sign up?

No. There are no accounts on this site at all — nothing to sign up for, and nothing to buy. Every calculator is free and works immediately.

Are the prices regional?

Labor pricing is adjusted by a regional multiplier (0.88 for low-cost regions to 1.45 for major metros). Materials are national averages — they don't vary as much as labor.

Can contractors use this?

Yes — both for sanity-checking their own numbers and for walking a client through what a scope actually includes. Every calculator lists the published sources behind its cost data, so you can see where a figure came from.
