Licence and attribution

The widget is free to use on personal, educational and commercial sites. The only condition is that you keep the “Powered by Cost Ripple” attribution link visible, or keep the credit line included in the snippet. Please do not modify the calculation logic or present the tool as your own.

Figures are illustrative projections, not financial advice. See our methodology for the assumptions behind the numbers.

Frequently asked questions

Will it slow my page down?: No. The iframe is lazy-loaded, so it only downloads when a reader scrolls to it.
Does it work on mobile?: Yes. The widget is fully responsive and the resize script keeps the frame height matched to the content.
Can I embed it in WordPress?: Yes. Paste the snippet into a Custom HTML block. Squarespace, Ghost, Webflow and Wix code blocks work the same way.
