How the Roth Or Traditional 401k Calculator Works

The calculator requires a few essential inputs:

• Annual Income: Your current salary before taxes.
• Contribution Rate: Percentage of salary you plan to contribute.
• Employer Match: Optional, if your employer provides a matching contribution.
• Years Until Retirement: How long you plan to save.
• Expected Rate of Return: Estimated annual investment growth (commonly 5–8%).
• Current Tax Rate: Your current income tax rate.
• Future Tax Rate: Projected tax rate at retirement for Traditional 401k comparison.

Output:

• Total retirement savings for Roth 401k
• Total retirement savings for Traditional 401k
• Tax impact at contribution and withdrawal stages
• Comparison chart showing which plan may yield more after-tax retirement income

Calculation Logic:

1. Roth 401k: Contributions are post-tax; growth is tax-free. $$FV_{\text{Roth}} = \text{Contribution} \times \frac{(1 + r)^n - 1}{r}$$FVRoth​=Contribution×r(1+r)n−1​ where $r$r is the annual rate of return, $n$n is years until retirement.
2. Traditional 401k: Contributions are pre-tax; taxes are applied on withdrawals. $$FV_{\text{Traditional}} = \text{Contribution} \times \frac{(1 + r)^n - 1}{r} \times (1 - \text{Future Tax Rate})$$FVTraditional​=Contribution×r(1+r)n−1​×(1−Future Tax Rate)

This formula ensures a precise comparison, accounting for both contributions and taxation.

Practical Example

Suppose you earn $80,000 annually, contribute 10% of your salary, have a 5% employer match, plan to retire in 30 years, and expect a 7% annual return. If your current tax rate is 22% and your future rate is 20%, the calculator will estimate:

• Roth 401k: $1,020,000 (after-tax)
• Traditional 401k: $950,000 (after-tax)

This comparison shows that, given the assumptions, Roth 401k provides a higher after-tax retirement balance.
