ROTH vs Traditional 401(k)
This calculator compares a ROTH 401(k) to a traditional 401(k).
It discounts the investment in the ROTH contributions by the marginal tax rate to compare equal net tax contributions.
The "Traditional After-Tax Value Adjustment" discounts the traditional contributions by the future effective tax rate to provide an after-tax comparison.
After reaching your "Years until Retirement" we stop the annual contributions, but further illustrate the difference to show your option to not take distributions until your desired "End Year" date.
