Taxes are a crucial aspect of financial planning, especially when your income places you in different tax brackets. A Marginal Tax Rate Calculator helps you determine the tax rate that applies to your next dollar of income. Understanding your marginal tax rate is essential for making smart decisions about bonuses, investments, deductions, and retirement contributions.
Your marginal tax rate is the percentage of tax you pay on an additional dollar of income. It represents the highest tax bracket into which your income falls. This is not the same as your average tax rate, which is the total tax paid divided by your total income.
Income is taxed progressively, meaning different portions of your income are taxed at different rates. Only the income that falls into each bracket is taxed at that bracket’s rate.
| Tax Rate | Single Filers |
|---|---|
| 10% | $0 – $11,000 |
| 12% | $11,001 – $44,725 |
| 22% | $44,726 – $95,375 |
| 24% | $95,376 – $182,100 |
| 32% | $182,101 – $231,250 |
| 35% | $231,251 – $578,125 |
| 37% | $578,126+ |
If you earn $80,000 annually as a single filer, your marginal tax rate is 22%. However, your average tax rate is lower, because only the portion over $44,725 is taxed at 22%.
The calculator determines:
