Put a calculator on your own site
Every calculator on FounderCalc can be embedded on your blog, your pricing page, your help centre or a client proposal. Open any tool, click Embed this calculator on your site, and paste the two lines of code where you want it to appear. The calculator runs entirely in your visitor's browser: nothing they type is sent to FounderCalc or anyone else, and it works on WordPress, Webflow, Ghost and plain HTML.
The free embed is free for good. It carries a small credit line that links back to the calculator's page here, and that is the whole cost.
What Pro adds
- No credit line. The calculator appears as part of your site, not as a widget borrowed from someone else's.
- Your brand colour. Buttons, highlights and results take the accent colour you choose instead of FounderCalc green.
- Every calculator, one key. One Pro key works on all 105 calculators, on as many pages as you like.
- A say in what comes next. Pro subscribers' requests for new calculators and new inputs are built first.
How it works
- Subscribe with the button above. Payment is handled by Stripe; FounderCalc never sees your card.
- Within one business day you receive your Pro key by email, with your embed code already updated to use it.
- Replace the embed code on your pages. The credit line disappears and your colour applies straight away.
Who uses it
Accountants and fractional CFOs who want a fee or runway calculator on their own site, SaaS companies that explain their pricing with a live calculation, agencies building resource pages for clients, and newsletter writers who send readers to a tool that looks like their own.
