A good calculator gives your visitors a reason to stay on your page and come back later. Besides, it answers the question they arrived with, without you building or looking after anything.
Our free website calculators also fit neatly into blog posts. For example, a post about buying a first home works better with a stamp duty calculator right underneath it.
Simple rules for using our calculators
- Use them free on personal, business, school and charity websites.
- Keep the credit link under the calculator visible.
- Do not change the calculator or present it as your own.
- Do not use them on sites that mislead people about money.
Free website calculators: your questions answered
Do the calculators cost anything?
No. Every calculator on this page is free to add to your website, and there is nothing to sign up for.
Will a calculator slow down my website?
No, it should not. That is because the calculator only loads when a visitor scrolls near it, so the rest of your page loads as normal.
Does the calculator fit on mobile?
Yes. In fact, the calculators resize to fit the space on your page, so they work on phones, tablets and computers.
Do you see what my visitors type?
No. The calculators run in your visitor’s own browser, so the figures they type are not sent to us.
Can I change the colours?
Not at the moment, unfortunately. However, every calculator uses the Iceburg Wealth design, which works on both light and dark websites.
