Net Pay Calculator

Taxes are the big chunk: federal (10–37%), state (0–13%), local (0–4%), FICA (7.65%). Average effective rate: 20–30%. Plus pre-tax deductions (401k, HSA).

401k, HSA, etc. reduce taxable income. $10k in 401k contributions = $2–3k in federal tax savings (assuming 22–24% bracket). Reduces gross but improves net.

More allowances = less withholding = higher net pay but big tax bill in April. Fewer = overpay but get refund. Aim for break-even (file updated W-4 annually).
