About This Calculator

This calculator estimates your net paycheck amount, accounting for pre-tax deductions like 401(k) contributions and health insurance premiums (which reduce your taxable income) before applying federal income tax and FICA withholding.

How This Is Calculated

Net Pay = Gross Pay − Pre-Tax Deductions − Federal Tax − FICA

A $75,000 salary with 6% to 401(k) and $2,400 in health premiums nets roughly $58,900/year after tax and deductions.

Assumptions

  • Uses 2026 federal tax brackets and standard deduction (IRS Rev. Proc. 2025-32).
  • Assumes 401(k) contributions and health insurance premiums are pre-tax (traditional 401(k), not Roth) and reduce both federal taxable income and FICA wages.
  • Does not include state or local income tax.
  • Does not include other deductions like HSA, FSA, or post-tax benefits.

Frequently Asked Questions

Traditional (pre-tax) 401(k) contributions reduce your taxable income for federal income tax purposes, lowering your tax bill now — you pay tax on withdrawals in retirement instead. Roth 401(k) contributions don't reduce current taxable income, since they're made with after-tax dollars.
