What This Calculator Does
This paycheck calculator converts annual gross salary to per-paycheck net pay using 2026 federal income tax brackets, W-4 withholding methodology, FICA taxes (Social Security and Medicare), state income tax, and pre-tax deductions including 401(k), health insurance, and HSA contributions. It supports weekly, bi-weekly, semi-monthly, and monthly pay frequencies and calculates effective federal and total tax rates.
The Formula
Federal withholding is calculated by annualizing the per-period gross pay, subtracting the standard deduction ($14,600 single, $29,200 married in 2026) and pre-tax deductions, applying the tax brackets, subtracting dependent credits ($2,000 per child), and dividing by the number of pay periods. Social Security is 6.2% on wages up to $176,100 (projected 2026 wage base). Medicare is 1.45% on all wages plus an additional 0.9% on wages above $200,000. Pre-tax deductions reduce both taxable income and take-home pay but provide tax savings.

Real-World Use Cases
Budget Planning
Know your exact per-paycheck take-home amount to create an accurate monthly budget and track cash flow.
Job Offer Evaluation
Convert competing salary offers to net pay factoring in different state tax rates, benefit costs, and retirement contributions.
401(k) Optimization
See how increasing your 401(k) contribution percentage affects take-home pay. Pre-tax contributions reduce your tax bill, so the impact on net pay is less than the contribution amount.
Common Mistakes to Avoid
Not updating your W-4 after major life events. Marriage, divorce, having children, or starting a second job all affect withholding accuracy.
Confusing bi-weekly (26 paychecks) with semi-monthly (24 paychecks). Two months per year, bi-weekly employees receive three paychecks instead of two.
Forgetting the Social Security wage base cap. Once annual earnings exceed $176,100 (2026), no additional Social Security tax is withheld. Paychecks in Q4 may be slightly larger for high earners.
Not accounting for the additional 0.9% Medicare tax on wages above $200,000. This is withheld by the employer but only from the employee share.
