Bracket breakdown
Each bracket's tax bill as its own bar, left to right from the 10% bracket to the 37% bracket — the connected dots trace the marginal rate climbing from bracket to bracket on the axis at right. The table below spells out the calculation, bracket by bracket.
Bracket-by-bracket calculation
| Bracket | Range | Taxed in bracket | Calculation | Tax owed |

Tax owed vs. taxable income
The total tax bill as taxable income rises from $0 to $800,000 — the line bends at each bracket boundary, where the slope steps up to that bracket's marginal rate. Move the mouse along the curve to check any income; the solid dot tracks the amount set on the left.
