Roth vs. Traditional 401(k): The Tax Bracket Bet
Choosing between Roth and Traditional 401(k) contributions is a bet on your future tax bracket. Pay taxes now or later? The right answer depends on income trajectory and retirement goals.

Roth 401(k): pay taxes now
Roth contributions are after-tax, but withdrawals are tax-free later. This can be powerful if you expect a higher tax bracket in retirement.
Traditional 401(k): defer taxes
Traditional contributions reduce taxable income now, but withdrawals are taxed later. This usually wins when your retirement tax rate is lower.
How to make the bet
If you're early in your career or expect higher income later, Roth often makes sense. If you're in a high tax bracket now, Traditional can deliver bigger savings.
