Estimate one paycheck and annual take-home pay from an annual salary or hourly wage. The calculation includes the official 2026 federal percentage method, Social Security, Medicare, W-4 adjustments, payroll deductions, and an optional state/local withholding estimate.
Examples
Biweekly salary
An annual salary of $78,000 produces $3,000 gross pay over 26 biweekly checks. Change the W-4 and deduction fields to mirror the latest pay stub.
Hourly overtime
At $30/hour, 40 regular hours and five overtime hours at 1.5× produce $1,425 gross per week before taxes and deductions.
Formula
For salaried work, gross pay is annual salary divided by checks per year. Hourly pay includes regular hours plus overtime hours at the selected multiplier.
taxable paycheck = gross paycheck − pre-tax deductions
net paycheck = gross − taxes − pre-tax deductions − post-tax deductions
Federal withholding follows Worksheet 1A logic: annualize taxable wages, add W-4 Step 4(a), subtract Step 4(b) and the standard Worksheet 1A adjustment ($12,900 for married filing jointly or $8,600 otherwise, unless Step 2 is checked), apply the proper annual table, subtract Step 3 credits, divide by pay periods, and add Step 4(c).
Sources and limits

The state/local field applies one user-entered percentage. It does not reproduce a state payroll system, and the pre-tax field assumes the full entered deduction reduces the wage base used by this estimate. Year-to-date wages can also change Social Security and Additional Medicare withholding on an actual paycheck.
