Free Calculators for Your Site

If you write about software costs, SaaS pricing, or running a lean online business, any of these 12 calculators are free to embed - no signup, no fee, no ongoing dependency on us beyond the iframe itself. Pick the one that fits your article, copy the snippet below it, and paste it in.

How it works

  • Each snippet is a single, responsive iframe - no script tags, no tracking beyond what your own site already runs.
  • We keep the calculators up to date on our end, so the embedded version stays current automatically.
  • A small text credit link sits below the iframe. That's the only attribution we ask for.
  • Free to use on any site, no permission needed - if you'd like a specific calculator built for your niche, see our contact page.
