How to Use the US Paycheck Calculator

Enter your gross annual salary, choose single or married filing status, and select a pay frequency (annually, monthly, biweekly, or weekly) to see your estimated take-home pay for that period, along with a breakdown of federal tax, Social Security, and Medicare.

The US Paycheck Calculator is built around a single salary input with a few adjustable settings — here's what each one changes in the result.

The three inputs

Gross annual salary should be your full pre-tax yearly pay. Filing status (single or married filing jointly) changes both the standard deduction applied and the income thresholds for each tax bracket, so choosing correctly matters for accuracy.

Pay frequency doesn't change your annual take-home total — it just changes how that total is divided and displayed, useful for matching the number to how you actually budget month to month or paycheck to paycheck.

Reading the breakdown

Below the headline take-home figure, the calculator shows federal tax, Social Security, and Medicare as separate line items, plus your effective tax rate — the percentage of gross income that went to these combined deductions. This breakdown makes it easy to see which deduction is largest and how the effective rate changes as income moves between brackets.

Frequently asked questions

Why doesn't the result match my actual paycheck exactly?

This calculator covers federal tax, Social Security, and Medicare only — it doesn't include state or local taxes, or any pre-tax benefit deductions like 401(k) or health insurance, both of which further change an actual paycheck.

Can I use this to test how a raise affects my take-home?

Yes — entering a new salary figure shows the updated take-home instantly, which is a quick way to see how much of a raise actually reaches your paycheck after tax.
