Questions about the roth contributions within your retirement plan
Can I make Roth contributions in my workplace plan?
Increasingly yes — many 401(k), 403(b) and 457 plans now offer a Roth option, and unlike a Roth IRA there is no income limit to contribute.
Why choose Roth contributions?
You pay tax now for tax-free withdrawals later. It is attractive if you expect higher future taxes, want tax-free income in retirement, or are early in your career at a low rate.
Is the employer match also Roth?
Traditionally the match goes into a pre-tax account even if your contributions are Roth, though some plans now allow Roth matching. Pre-tax match money is taxed at withdrawal.
Is the Roth Contributions Within Your Retirement Plan free to use?
Yes. Every calculator on FinCalculators is completely free, with no sign-up, login or paywall. You can run as many scenarios as you like.
