Frequently Asked Questions
What deductions come out of my gross pay?
Standard deductions include federal income tax, state income tax (varies by state), Social Security (6.2% up to the wage base), Medicare (1.45%), and any voluntary pre-tax elections like 401(k) or health insurance. Post-tax items like Roth 401(k) come out after taxes are calculated.
How do pre-tax deductions reduce my net pay?
Pre-tax deductions reduce your taxable income, which lowers your federal and state income tax. However, FICA (Social Security and Medicare) is still calculated on your full gross salary. The net effect is a smaller tax bill but slightly less take-home after the deduction itself.
Does my state tax show up in the waterfall?
Yes — this calculator shows your state's income tax as a separate deduction row. If you're in a no-tax state like Texas, Florida, or Washington, that row shows $0.
