For contractors & estimators

BuildCalculator's calculators are free to embed on your own website — a ready-made lead magnet for your customers, with no development work on your end.

Embed any calculator free

Every calculator page has a copy-paste embed snippet near the bottom. It drops a live tool onto your site in an iframe and includes a small attribution link back to BuildCalculator. Popular ones to start with:

• Sand calculator
• Topsoil calculator
• Siding calculator
• Asphalt calculator
• Rebar calculator
• Drywall calculator
• Retaining Wall calculator
• Roofing calculator

Pro estimating tools (coming soon)

We're building a Pro version: white-label embeds without our branding, saved job estimates, regional price presets you control, and CSV export. Want early access? Email [email protected] with "Pro" in the subject and we'll add you to the list.

A note on pricing data

We deliberately keep install-cost estimates off our public tools because real quotes vary too much by region to publish honestly. The Pro version will let you set your own regional rates so the numbers reflect your market — never a made-up national average.
