- Annual Gross = Base Income + Annual Bonus + (Additional Income per Period × Periods per Year)
- Pre-tax (Annual) = (Retirement % × Gross per Period + Fixed Pre-tax per Period) × Periods per Year
- Annual Taxable Income = max(0, Annual Gross − Pre-tax − Annual Taxable Reduction)
- Federal Tax = Taxable Income × Federal Rate (flat) or sum of bracket slices (progressive)
- Total Taxes = Federal + State + Local + Other + Social Security + Medicare (+ Medicare Additional)
- Net Take-Home (Annual) = Annual Gross − Pre-tax − Total Taxes − Post-tax
- Net Take-Home (Per Period) = Net Take-Home (Annual) ÷ Periods per Year

Inputs
The calculator accepts three income styles: annual salary, gross per pay period, or hourly wages with overtime. Hourly gross is computed as (hourly rate × regular hours) + (hourly rate × overtime multiplier × overtime hours) each week, then annualized by weeks worked. This flexibility helps model contractors, shift workers, and salaried employees.
Deductions
Pre-tax deductions reduce taxable income before rates are applied. Retirement contributions are calculated as a percentage of gross per period, while benefits like health insurance and HSA/FSA are entered as fixed per‑period amounts. For example, on a $6,666.67 monthly gross, a 5% retirement rate is $333.33, and $120 insurance brings pre-tax to $453.33. You can also apply an annual taxable reduction (such as standard deductions) to stress-test outcomes.
Taxes
Taxes can be estimated with a flat effective federal rate or custom progressive brackets. With brackets, each slice of annual taxable income is taxed at its assigned percentage, then summed for total federal tax. Add state, local, and other rates for a more complete view. Optional social-program fields support capped wage bases and additional-rate thresholds, letting you model scenarios where payroll taxes stop after a limit or increase above a specified income level.
Visualization
After you calculate, the Plotly waterfall chart visualizes one pay period: it starts at gross pay, then steps down by pre-tax deductions, taxes, and post-tax deductions, finishing at net take‑home. If gross is $3,000 per period, and pre‑tax is $200, taxes are $450, and post‑tax is $50, the ending net is $2,300. This format makes it easy to see which component is driving changes.
Reporting
For planning, compare two runs that differ by only one assumption—such as retirement percent or federal rate—and record the effective tax rate and net ratio. Use the CSV export for spreadsheet tracking and the PDF export for a clean snapshot to share with a partner or advisor. Re-export after each adjustment so your budget reflects the latest deductions, overtime patterns, and withholding choices across periods and years.
FAQs
1) What does “Annual Taxable Income Reduction” represent?
It’s an annual subtraction from gross after pre-tax deductions, such as a standard deduction, allowances, or non-taxable adjustments. It reduces the income base used for federal, state, and local tax calculations.
2) Should I use a flat federal rate or brackets?
Use a flat rate for quick estimates when you know your effective withholding. Use brackets when you want a progressive structure by income ranges. Brackets are best for scenario planning and sensitivity testing.
3) How is overtime handled in hourly mode?
Weekly gross includes regular hours at the hourly rate and overtime hours multiplied by the overtime multiplier. That weekly total is annualized by weeks worked and then converted into per‑period values using your selected pay frequency.
4) Why might my net pay show as negative?
Negative net can occur if you enter deductions or tax rates that exceed gross pay, or if taxable income reductions are too low for the chosen rates. Review pre‑tax, post‑tax, and tax inputs to correct assumptions.
5) What’s the difference between pre-tax and post-tax deductions?
Pre-tax deductions reduce taxable income before taxes (often lowering tax owed). Post-tax deductions are taken after taxes are calculated and reduce net pay dollar-for-dollar without directly reducing the taxable base.
