Take-home pay (net pay) is what remains after your employer withholds income taxes, Social Security, Medicare, and any other mandatory deductions from your gross salary.
**How income tax works (US example):**
The US uses a progressive tax system — different portions of your income are taxed at different rates (brackets). Only income within each bracket is taxed at that rate, not your entire salary. For example, at a $75,000 salary in 2025:
• First $11,925: taxed at 10% = $1,192.50
• $11,926–$48,475: taxed at 12% = $4,386
• $48,476–$75,000: taxed at 22% = $5,835.28
• Total federal tax: $11,413.78
• Effective rate: ~15.2% (not the marginal 22%)
**Additional US deductions:**
• Social Security: 6.2% on income up to the wage base ($176,100 in 2025)
• Medicare: 1.45% on all income (+ 0.9% surtax above $200,000)
• State income tax: 0% (TX, FL, NV) to ~13% (CA)
This calculator provides estimates using simplified brackets — actual withholding varies by filing status, pre-tax deductions (401k, FSA), and individual circumstances.
