Average Tax Rate Calculator
Calculate your average (effective) tax rate from total tax paid and income.
Understand the difference between average, marginal, and effective rates with 2024 US tax brackets.
Average Tax Rate vs Marginal Tax Rate
These are two of the most confused concepts in personal finance — and understanding the difference can change how you think about every financial decision.
Average Tax Rate
Also called the effective tax rate — it is the percentage of your total income that you actually paid in taxes.
Average Tax Rate = Total Tax Paid ÷ Taxable Income × 100
Effective Tax Rate (on Gross Income)
A slightly different version that uses total gross income (before deductions) as the denominator:
Effective Rate = Total Tax Paid ÷ Gross Income × 100
Marginal Tax Rate
The tax rate on your last dollar earned — the rate applied to the top slice of your income. This is your tax bracket.
A common misconception: people think moving into a higher bracket means ALL their income is taxed at that rate. This is wrong. Only the income above the bracket threshold is taxed at the higher rate. Every dollar below is still taxed at the lower bracket rate.
2024 US Federal Tax Brackets (Single Filers)
| Taxable Income Range | Marginal Rate |
|---|---|
| $0 – $11,600 | 10% |
| $11,601 – $47,150 | 12% |
| $47,151 – $100,525 | 22% |
| $100,526 – $191,950 | 24% |
| $191,951 – $243,725 | 32% |
| $243,726 – $609,350 | 35% |
| Over $609,350 | 37% |
2024 US Federal Tax Brackets (Married Filing Jointly)
| Taxable Income Range | Marginal Rate |

| $0 – $23,200 | 10% |
| $23,201 – $94,300 | 12% |
| $94,301 – $201,050 | 22% |
| $201,051 – $383,900 | 24% |
| $383,901 – $487,450 | 32% |
| $487,451 – $731,200 | 35% |
| Over $731,200 | 37% |
Worked Example (Single Filer, $85,000 taxable income)
- 10% on first $11,600 = $1,160
- 12% on $11,601–$47,150 = $35,550 × 12% = $4,266
- 22% on $47,151–$85,000 = $37,850 × 22% = $8,327
- Total Tax = $13,753
- Marginal Rate = 22% (the bracket you are in)
- Average Tax Rate = $13,753 ÷ $85,000 = 16.2%
The average rate is always lower than the marginal rate — this is guaranteed by the progressive tax system.
Pro Tips
- Use the marginal rate when deciding whether to take on extra income (freelance work, Roth conversions, etc.) — that rate tells you the cost of the next dollar earned.
- Use the average rate to understand your true overall tax burden.
- Standard deduction for 2024: $14,600 (single), $29,200 (married filing jointly). Subtract from gross income to get taxable income.
- State income taxes are separate and additional — this calculator covers federal only.
