Immediate Tax Savings = Annual Contribution × Current Marginal Tax Rate %Contributions reduce your taxable income dollar-for-dollar up to IRS annual limits, lowering current-year tax liability while deferring taxes until retirement.
Variables Explained:
- Annual Contribution ($): Up to $7,000/year (or $8,000 for age 50+).
- Current Marginal Tax Bracket %: Your current federal income tax rate (e.g. 22%, 24%, 32%).

- Immediate Tax Refund: $7,000 × 0.24 = $1,680 in tax savings this year.
- Net Out-of-Pocket Cost: $7,000 - $1,680 = $5,320.
