How is tax percentage calculated?
Tax percentage or effective tax rate tells what portion of your gross income goes to taxes. The calculator calculates it with the formula:
Tax percentage = paid taxes ÷ gross salary × 100
Gross salary is the sum of net salary and paid taxes. The calculator also shows annual gross income and total taxes.
US taxation parts
In the US, several different taxes and contributions are withheld from salary:
| Part | Nature | Typical level |
|---|---|---|
| Federal income tax | Progressive | 0–37% |
| State income tax | Progressive or flat | 0–13.3% |
| Social Security tax | Flat | 6.2% |
| Medicare tax | Flat | 1.45% |
Effective vs. marginal tax percentage
- Effective tax percentage tells the real tax burden relative to gross income — this is what the calculator shows
- Marginal tax percentage tells how much tax you pay on additional dollar — can be over 40% including side costs
In practice, the effective total tax rate (all withholdings included) for an average American is typically 20–35%.
Tips for taxation
- Check your W-2 annually on IRS website — too high withholding ties up money unnecessarily
- Remember to claim deductions, credits and other adjustments on your tax return
- If income changes significantly mid-year, update your W-4
