Step by step
Open Roth Conversion Calculator
Visit /tools/roth-conversion-calculator in any modern browser. The tool loads instantly and runs entirely on your device, so no inputs are transmitted to a server.
Gather your inputs
Have your traditional ira balance, marginal tax rate, future rate, years ready. Accuracy on the output depends entirely on the quality of these numbers. If a value is uncertain, use the most realistic figure rather than rounding aggressively.
Enter the values
Fill each field in turn. Roth Conversion Calculator validates ranges as you type, so an obvious typo (for example a negative balance where one cannot exist) will flag immediately.
Read the result
The output is a net after tax balance for each path, computed using tax now versus tax later with bracket awareness. Treat it as a precise answer to the question you posed, not an approximation.
Verify and compare
Re-run the calculation with a slightly different input to test sensitivity. For deeper comparison against another approach, see related tools in the Conversions hub or pick a related roth conversion tool below.
