How it works
These widgets run entirely in your visitor's browser. They do not use a paid API or require a login. They show the calculations and a small attribution link to the full MyFastCalcTools calculator. Please do not remove that attribution or imply that the widget provides financial advice.
Embeds are provided as-is. Some website builders block iframes, and your publishing platform must permit embedding external HTTPS pages. Test on your own mobile layout before publishing. We may update the calculator's design and formulas over time.
Worked examples can help explain how to interpret results.
