Your salary and your take-home pay are two very different numbers — and understanding the gap is one of the most important financial calculations you can make. Between federal income tax, Social Security, Medicare, and state taxes, a $100,000 salary in a high-tax state might net you $68,000–$72,000. In a no-income-tax state, that same salary might yield $76,000–$79,000. This calculator shows exactly where your money goes. Enter your gross income, filing status, and state to see your federal income tax broken down by bracket, your FICA contributions (Social Security at 6.2% and Medicare at 1.45%), your effective rate, and your true monthly and annual take-home pay. Many people mistakenly believe they're "in the 22% bracket" and fear earning more will hurt them. In reality, marginal tax rates only apply to income above each threshold — not your entire salary. On a $55,000 single-filer income, only the income between $47,150 and $55,000 is taxed at 22%. The rest is taxed at 10% and 12%. Understanding this distinction changes how you think about raises, bonuses, 401(k) contributions, and side income.
- ·Uses 2024 federal tax brackets and the standard deduction ($14,600 single, $29,200 married filing jointly)
- ·Does not account for itemized deductions, tax credits (EITC, child tax credit, etc.), or investment income
- ·State tax is a representative rate — states with progressive brackets may differ slightly from actual liability
- ·FICA Social Security wage cap: $168,600 in 2024
- ·Self-employment tax (15.3%) is not calculated — this applies to W-2 employees only
Federal income tax uses progressive brackets (2024, single): · 10% on first $11,600 · 12% on $11,601–$47,150 · 22% on $47,151–$100,525 · 24% on $100,526–$191,950 · 32% on $191,951–$243,725 · 35% on $243,726–$609,350 · 37% on income above $609,350 Tax = sum of each bracket's rate × income within that bracket, applied to (Gross income – Standard deduction). FICA = (6.2% Social Security on income up to $168,600) + (1.45% Medicare on all income). Effective rate = Total federal tax ÷ Gross income (always lower than your marginal bracket).

Example 1: $85,000 salary, single filer, Texas (no state tax)
Inputs: Gross: $85,000 · Filing: single · State: Texas
Result: Federal tax: $12,907 (effective rate 15.2%) · Social Security: $5,270 · Medicare: $1,233 · Total tax: $19,410 · Take-home: $65,590/yr ($5,466/mo)
Despite being in the 22% marginal bracket, the effective federal rate is 15.2% — because the first $14,600 is untaxed (standard deduction) and lower brackets apply to most income. A $5,000 raise nets $3,600 after tax, not $3,900.
Example 2: Same income, California vs. Texas
Inputs: Gross: $85,000 · Filing: single · California vs. Texas
Result: Texas: Take-home $65,590/yr | California (est. 6% state rate): Take-home ~$60,490/yr · Difference: $5,100/year
State income tax costs approximately $425/month in California vs. zero in Texas on the same salary. Over 10 years, that's $51,000+ — a significant factor when comparing job offers in different states.
- ✕Thinking a raise could put you in a higher bracket and cost you money — marginal rates only apply to income above each threshold, never to your full salary
- ✕Forgetting FICA taxes when budgeting — Social Security + Medicare add 7.65% on top of income tax
- ✕Not adjusting W-4 withholding after a major life change (marriage, new child, second job) — can result in a large underpayment penalty
- ✕Ignoring the tax savings from pre-tax 401(k) contributions — contributing $500/month only reduces take-home by ~$385 in the 22% bracket
- ✕Comparing gross salary job offers across states without adjusting for state income tax differences
What is the difference between marginal and effective tax rate?
Your marginal rate is applied to your last dollar of income — it's the highest bracket you fall into. Your effective rate is total tax ÷ gross income. If you're in the 22% bracket, your effective rate might only be 15% because lower income dollars were taxed at 10% and 12%. Only income above each threshold is taxed at the higher rate.
What is FICA and is it separate from income tax?
FICA (Federal Insurance Contributions Act) covers Social Security (6.2% on income up to $168,600 in 2024) and Medicare (1.45% on all income). These are separate from federal income tax — they fund specific programs and are calculated differently. If you're a W-2 employee, your employer matches these amounts dollar-for-dollar.
What is the 2024 standard deduction?
$14,600 for single filers and $29,200 for married filing jointly. This reduces your taxable income before brackets are applied. Most people take the standard deduction rather than itemizing, unless deductible expenses (mortgage interest, state taxes, charitable donations) exceed these amounts.
How do pre-tax 401(k) contributions affect my taxes?
Pre-tax 401(k) contributions reduce your taxable income dollar-for-dollar. If you're in the 22% bracket, a $500/month contribution only reduces your take-home by about $385 — the other $115 comes from reduced tax. This is the most common under-appreciated benefit of 401(k) contributions.
What if I have multiple jobs or freelance income?
Each income source adds to your total taxable income and may push you into higher brackets. W-2 employers withhold taxes based on your W-4, but side income typically has no withholding. You may need to make quarterly estimated tax payments on freelance income to avoid a penalty. Add all income sources together in this calculator to estimate your full tax burden.
