Embed Our Free Calculators on Your Site
Advertisement
Give your readers a working cost calculator without writing one. Paste a snippet, get a live mini-calculator — free forever, no signup, no API key.
How it works
- Copy the snippet for the calculator you want below.
- Paste it anywhere in your page's HTML where you want the calculator to appear.
- Done — the calculator renders automatically, styled to work on any site.
The widget is style-isolated (Shadow DOM), so your theme can't break it and it can't break your theme. It works in all modern browsers and is fully responsive.
Paint Cost Calculator
Room dimensions in, gallons + total cost out. Same October 2026 price defaults as our full paint cost calculator.
Moving Cost Calculator
Home size + distance in, DIY / container / full-service estimates out. Matches our full moving cost calculator.
Solar Cost Calculator
Monthly bill in, system size + payback out. Same October 2026 defaults as our full solar cost calculator.
Customization
- Width: the widget fills its container up to 420px — put it in a sidebar, a narrow column, or full-width content and it adapts.
- Multiple calculators: add one
<div data-cmp-calculator="...">per calculator; the script tag only needs to appear once per page. - More calculators coming: flooring, fence, deck, roof, and siding widgets are on the roadmap — this page will be updated as each ships.
Terms (short version)
- Free for any website — personal blog, contractor site, news outlet, anyone.
- Keep the "Powered by CostMyProject" attribution link intact. That's the whole price.
- Don't misrepresent the numbers as quotes — they're planning estimates (±25%), same as on our site.
- We may update prices and the widget code; embeds always use the latest version automatically.
