What is the salary calculator?
In short
A $75,000 salary takes home roughly $54,000–$58,000 per year ($4,500–$4,833/month) after federal income tax, state tax, Social Security (6.2%), and Medicare (1.45%). The exact amount depends on your state: no-income-tax states like Texas or Florida keep $3,000–$4,000 more per year than high-tax states like California. A $10,000 pre-tax 401(k) contribution reduces your federal taxable income by $10,000 — saving roughly $2,200 in federal tax at the 22% bracket. At $100,000 gross, a single filer in a 5% flat-tax state takes home approximately $71,000/year ($5,917/month) after all deductions.
This salary calculator estimates your US take-home pay after federal income tax (2026 brackets), Social Security, Medicare, state income tax, and pre-tax deductions. It shows annual, monthly, biweekly, weekly, and hourly equivalents. Enter your gross salary once and instantly see what every paycheck actually puts in your pocket — useful when comparing job offers, evaluating a raise, or deciding how much to contribute to your 401(k).

Worked example
The scenario
$75,000 gross, single filer, 5% state tax, $6,000 in 401(k) contributions.
The result
Taxable income = $75,000 − $6,000 − $15,000 standard deduction = $54,000. Federal tax ≈ $6,904. State tax = ($75,000 − $6,000) × 5% = $3,450. FICA = $75,000 × 7.65% = $5,738. Take-home ≈ $52,908/year or $4,409/month.
Common use cases
- Comparing job offers in different states
- Deciding how much of a raise is actually take-home
- Planning a budget using real net income
- Estimating the tax saving from 401(k) contributions
