How is take-home pay calculated?

Take-home pay is your gross salary minus federal income tax, state income tax, FICA (Social Security + Medicare), 401k contributions, and health insurance premiums. The remainder is your net monthly or biweekly paycheck.

What is FICA and how much is it?

FICA stands for Federal Insurance Contributions Act. It covers Social Security (6.2%) and Medicare (1.45%), totaling 7.65% of gross wages for employees in 2026. Your employer matches this amount separately.

Do 401k contributions reduce my taxable income?

Yes. Traditional 401k contributions are pre-tax, meaning they reduce your federally and state taxable income before income tax is calculated. FICA is still owed on your full gross wages.

What is an effective tax rate?

Effective total rate is the percentage of your gross monthly pay that goes to taxes, retirement contributions, and insurance combined. It differs from your marginal tax bracket because not all income is taxed at the top rate.

401k / retirement (%)

Pre-tax contribution reduces your taxable income.

Health insurance / month ($)

Your share of monthly premium (pre-tax if employer plan).

Why your bracket isn't your rate

Your marginal tax bracket applies only to income in that range, not your whole salary. Your effective federal rate is almost always lower than your bracket — often several percentage points lower.

The 401k leverage

A 6% contribution on a $65k salary saves roughly $858 per year in federal taxes alone (at 22% bracket). Employer matches are on top of that — essentially free money left on the table if you skip them.

How to use this take-home calculator

Start with your W-2 gross salary — not your offer letter total compensation, which includes benefits and bonuses. Enter your federal marginal bracket (the rate on your top dollar of income), your state income tax rate, and your actual 401k deferral percentage.

The calculator follows the source ProfitToolsLab formula exactly: gross monthly equals gross annual divided by 12; retirement deduction equals gross monthly multiplied by the 401k rate; taxable monthly equals gross monthly minus retirement deduction; federal and state taxes are applied to taxable monthly; FICA applies to full gross monthly. Net equals gross monthly minus all taxes, retirement, and health insurance premium.

For biweekly pay, divide net monthly by 2. This is an approximation — some months have three biweekly pay periods, which shifts the timing but not the annual total.

Use the effective total rate to gut-check whether your paycheck feels right. If the rate seems too high, check whether you entered rates as percentages (22, not 0.22). If it seems too low, verify you included FICA — it is often forgotten but adds 7.65 percentage points.

Rerun the calculator at 3%, 6%, and 10% 401k contributions to see how much you can take home now versus how much you are trading for future tax-advantaged savings.
