Marginal vs Effective Tax Rate Reveal
Example: Annual gross income: 95000 $ · Filing status (0 = Single, 1 = Married Filing Jointly): 0 · Custom deduction (0 = use 2025 IRS standard): 0 $
| Effective tax rate | 13.17% |
| Marginal (bracket) rate | 22.00% |
| Gap: marginal minus effective | 8.83% |
| Income room left in current bracket | $23,350 |
| Estimated federal tax owed | $12,514 |
Worked example
A single filer earning $95,000 is technically in the 22% bracket, but after the $15,000 standard deduction their taxable income is $80,000. The 22% rate applies only to dollars above $48,475 — the first $48,475 of taxable income is taxed at 10% and 12%. The result: they owe about $13,605, an effective rate of 14.3%. They still have about $23,350 of room before crossing into the 24% bracket — ideal for a Roth conversion.
Frequently asked questions
Why does my marginal rate feel higher than I expected?
The marginal rate is the rate on the last dollar of income. Many people are in a 22% or 24% bracket yet their effective rate is closer to 14–18% because earlier dollars are taxed at lower rates. The gap shows how much of a buffer you have.
How can I use the bracket room shown here?
The room remaining in your current bracket is useful for planning Roth IRA conversions, realizing long-term capital gains at the 0% or 15% LTCG rate, or timing year-end bonuses and freelance income. Converting traditional IRA dollars up to the top of a lower bracket means each dollar converts at that bracket's rate, not a higher one.
Does this include state income tax?
No — this calculator covers federal income tax only using 2025 IRS brackets. State income tax varies widely; add your state rate separately for a complete picture.
