Does this calculator include federal and state tax brackets automatically?

No. This tool uses your effective tax-rate assumptions to model planning outcomes.

Can I model a bonus with my raise?

Yes. Add an optional one-time bonus and a bonus withholding rate to estimate first-year net gain.

Estimate how much of your raise you actually keep per paycheck, per month, and per year after withholding assumptions.

Current annual salary ($)

Raise percentage (%)

Pay periods per year

Pre-tax deductions per paycheck ($)

Post-tax deductions per paycheck ($)

Current effective tax rate (%)

Projected effective tax rate after raise (%)

One-time bonus ($, optional)

Bonus withholding rate (%)

Enter values and run calculation.

Start with current effective rate from recent pay stubs, then test a higher rate for your raise scenario.
Model at least two cases: base assumptions and a conservative "higher tax" case.
Use this for planning and negotiation prep, then confirm actual withholding setup with payroll/tax guidance.
