How it works

We apply 2024 IRS tax brackets for single or married filing jointly statuses, summing the tax owed at each bracket.

Effective rate = total tax ÷ taxable income. Marginal rate is the bracket rate for your last dollar of income.

Formula

Piecewise tax calculation using IRS brackets; see plan docs for current thresholds.

When to use it

  • Estimating taxes on a raise, bonus, or freelance income.
  • Understanding where your next dollar of income will be taxed.
  • Planning Roth vs traditional contributions by looking at marginal rates.

Tips & cautions

  • Use taxable income, not gross salary—deductions and pre-tax contributions reduce the number you enter.
  • Try multiple income amounts to see when you cross into a higher marginal bracket.
  • State/local taxes are separate; add them manually if you need a combined view.
  • Uses static 2024 US federal brackets; laws change and other filing statuses are not included here.
  • Does not model credits, AMT, or phaseouts that can change effective rates.
  • Outputs are estimates; real returns depend on your full tax situation.
