Common questions
Is it free?
It is currently free to use with no sign-up. We may introduce paid plans or limits in future, and will give notice before any change.
Do I need to know how to code?
No. Create a calculator by describing it or clicking, then copy and paste the result.
Where can I put the calculator?
Most places where you can paste a snippet of code, which covers the majority of websites and page builders.
Can I make a custom calculator for my website?
Yes. Everything here is a custom calculator: your fields, your formulas, your colours and fonts. The result is a small widget that matches your site rather than a generic embed.
How do I embed the calculator on my website?
Publishing gives you a short calculator embed code, just two lines. Paste it where you want the calculator widget on your website and it loads from our servers, so there is nothing to install or maintain.
Will it keep working later?
Once added to your site, a calculator is designed to keep running there, subject to our terms of use.
