Free calculators for your website
Let your customers work out how much gravel, mulch, concrete or lumber to order, right on your site.
How it works
- Copy one snippet from the list below and paste it into any page: WordPress, Wix, Squarespace, Shopify or plain HTML.
- Free, with no sign-up. No ads and no cookies inside the calculator, and nothing your customers type leaves their browser.
- Always up to date. It is the same calculator as on SumTakeoff, so fixes and new material options reach your site automatically.
- Sized for you. It fits any width down to a phone and grows to fit its results. Add
?theme=dark to the address for a dark version.
The one thing we ask is to keep the small "by SumTakeoff" line under the calculator.
