Free calculators for trade blogs and associations

Give readers a way to work through a job estimate using their own inputs. No account or payment is required. Calculator inputs stay in the reader's browser.

Choose a calculator, copy its embed HTML and paste it into your site's HTML editor. The snippet includes a credit link outside the frame. Keep that link so readers can inspect the full formula, assumptions and sources. Allow at least 760 pixels of height; narrow frames can scroll.

You can also copy the plain link HTML if your editor does not allow iframes. Examples are starting points, not local price recommendations.
