How to Calculate Take-Home Pay
Updated July 2026 · 8 min read
Your gross salary is the number on your offer letter. Your take-home pay — also called net pay — is what actually lands in your bank account after the government and your benefits plan have had their share. For most American workers, the gap is 25–40% of gross. Understanding each deduction gives you real control over your budget and your W-4 elections.

At its core, the calculation works like this:
Net Pay = Gross Pay
- Federal Income Tax
- Social Security Tax (6.2%)
- Medicare Tax (1.45%)
- State Income Tax
- Pre-Tax Deductions (401k, HSA, health premiums)
- Post-Tax Deductions (Roth 401k, garnishments)
= Take-Home Pay (Net Pay)
Step 1: Determine Your Gross Pay Per Period
Gross pay is your total earnings before any deductions. How it is calculated depends on how you are paid:
- Salaried: Annual salary divided by pay periods. Biweekly (26 periods): $75,000 / 26 = $2,884.62 per check.
- Hourly: Hourly rate multiplied by hours worked. $20/hr x 80 hours (biweekly) = $1,600.
- Overtime: Hours over 40/week are paid at 1.5x your regular rate under federal law.
- Commission/bonus: Added to regular pay for the period, increasing withholding that paycheck.
Common pay periods: weekly (52/year), biweekly (26/year), semi-monthly (24/year), monthly (12/year). Biweekly is most common in the US — two months per year you receive three paychecks instead of two.
Step 2: Subtract Pre-Tax Deductions
Pre-tax deductions reduce your taxable wages — not just your take-home. Common pre-tax deductions:
- Traditional 401(k) / 403(b): Up to $23,000 (2024); $30,500 if age 50+. Reduces federal and state taxable income (not FICA wages).
- Health Savings Account (HSA): $4,150 individual / $8,300 family (2024). Reduces federal income tax AND FICA — triple tax benefit.
- Flexible Spending Account (FSA): Up to $3,200 for healthcare FSA. Use-it-or-lose-it each year.
- Employer health, dental, vision premiums: Your share of premiums under a Section 125 cafeteria plan is pre-tax.
- Commuter benefits: Up to $315/month (2024) for transit or parking.
After subtracting pre-tax deductions from gross pay, you have your taxable wages — the number used to calculate income tax withholding.
Step 3: Federal Income Tax
Federal income tax uses a progressive marginal system. Your entire income is NOT taxed at your top bracket rate — only the income in each bracket is taxed at that rate.
| 2024 Tax Bracket (Single) | Rate |
|---|---|
| $0 – $11,600 | 10% |
| $11,601 – $47,150 | 12% |
| $47,151 – $100,525 | 22% |
| $100,526 – $191,950 | 24% |
| $191,951 – $243,725 | 32% |
| $243,726 – $609,350 | 35% |
| Over $609,350 | 37% |
Your W-4 elections tell your employer how to approximate the right withholding amount. If you consistently get a large refund (over $1,000), you are lending the IRS money interest-free. Filing an updated W-4 to withhold less increases your paycheck immediately.
Step 4: FICA Taxes (Social Security and Medicare)
- Social Security: 6.2% on wages up to $168,600 (2024 wage base). Stops once you exceed this amount in a calendar year.
- Medicare: 1.45% on ALL wages — no cap.
- Additional Medicare surtax: 0.9% on wages over $200,000 (single) / $250,000 (married filing jointly).
Unlike income tax, FICA is not affected by your W-4 or deductions (except certain Section 125 items). Your employer matches the 6.2% and 1.45% on your behalf.
Step 5: State and Local Income Tax
| State | Top Rate | Type |
|---|---|---|
| California | 13.3% | Progressive |
| New York | 10.9% | Progressive |
| New Jersey | 10.75% | Progressive |
| Oregon | 9.9% | Progressive |
| Minnesota | 9.85% | Progressive |
| Illinois | 4.95% | Flat |
| Pennsylvania | 3.07% | Flat |
| Texas / Florida / Nevada | 0% | No income tax |
Step 6: Post-Tax Deductions
- Roth 401(k): Taxed now, tax-free at retirement. Does not reduce current taxable income.
- Union dues: Deducted post-tax.
- Wage garnishments: Court-ordered deductions for child support, alimony, or student loan default.
- Life insurance over $50,000: Premiums on employer-provided coverage above $50k are imputed income (taxed).
Full Example: Biweekly Paycheck Breakdown
$100,000/year salary (biweekly = $3,846/check), single filer in Oregon, with $300 traditional 401(k), $100 HSA, $150 health insurance pre-tax:
| Item | Amount | Running Total |
|---|---|---|
| Gross Pay | +$3,846 | $3,846 |
| 401(k) pre-tax | -$300 | $3,546 |
| HSA contribution | -$100 | $3,446 |
| Health insurance | -$150 | $3,296 |
| Taxable wages | $3,296 | |
| Federal income tax (~22%) | -$530 | $2,766 |
| Social Security (6.2%) | -$238 | $2,528 |
| Medicare (1.45%) | -$56 | $2,472 |
| Oregon state tax (~8.75%) | -$288 | $2,184 |
| Take-Home Pay | $2,184 |
Take-home is $2,184 out of $3,846 gross — about 56.8% of gross pay. The effective total tax rate is 28.9%. Pre-tax deductions saved approximately $195 in taxes versus contributing nothing.
How to Legally Increase Your Take-Home Pay
- Adjust your W-4. If you get a refund over $1,000, you are over-withholding. A new W-4 with the correct deductions or credits boosts every paycheck immediately.
- Max out your HSA. HSA contributions reduce federal tax, state tax (in most states), AND FICA — triple tax advantage with indefinite rollover.
- Contribute more to a traditional 401(k). At 22% federal + 5% state, a $500 contribution only reduces net pay by about $365. The other $135 is tax savings.
- Use a Dependent Care FSA. Up to $5,000/year in daycare costs can be paid pre-tax if you have qualifying dependents.
- Negotiate benefits over salary. Employer-paid premiums and matching contributions are often worth more after-tax than an equivalent wage increase.
