Embed the Roth Conversion Calculator

What converting a traditional IRA to a Roth costs in tax now, what it is worth at withdrawal, and the retirement tax rate where the two paths break even. Set the values it should open on, then copy the iframe. Your visitors can change them; the widget recomputes against Rule Calculator and never touches your page.

Opening values

Set what the widget shows before anyone touches it. Leave a field as it is and it stays out of the URL.

Free for commercial use. The one condition is the credit link inside the widget, which is how the calculator stays free. Want the numbers in your own markup instead? The same calculator is a JSON endpoint, or see the full Roth Conversion Calculator page with its sources and working.
