Why use a Calcist calculator
- Free, with no ads. Nothing to sign up for and no ads inside the calculator.
- Private. No cookies, no tracking, and nothing your visitors type is sent anywhere. Everything is worked out in their browser.
- Checked. Every calculator is tested against independently worked answers before it's published.
- Fits your page. It resizes itself to fit its content, works on phones, and follows light or dark mode.
How to add one
- Open the calculator you want from the list below.
- Scroll to Add this calculator to your website near the bottom and press Copy code.
- Paste the code where you want the calculator: in WordPress, use a Custom HTML block; in Squarespace or Wix, use an Embed or Code block.
The code looks like this:
<iframe src="https://calcist.com/embed/mortgage-calculator/" title="Mortgage calculator" width="100%" height="640" loading="lazy" style="border:0;max-width:760px"></iframe> <p><a href="https://calcist.com/mortgage-calculator/">Mortgage calculator</a> by Calcist</p> <script src="https://calcist.com/embed.js" async></script>
Add ?theme=light or ?theme=dark to the end of the address in src to force a color scheme. Leave the small "by Calcist" link in place; it's how people find the full explanation.
