Take-Home Pay Explained: Why Your Salary Isn't What You Keep
Your gross salary and the money in your bank account are two different numbers. Here is exactly what gets deducted, how tax bands work, and how to estimate your net pay.
You negotiate a salary, sign the offer, and then the first payslip arrives, noticeably smaller than you expected. The number you agreed is your gross salary. The amount that actually reaches your account is your take-home (net) pay, and the gap between them catches almost everyone off guard at some point.
Here is what happens between the two, so your budget is built on the real number.
What gets taken out
Three main things shrink your gross pay:
- Income tax. Charged in bands (more on that below). This is usually the biggest deduction.
- Social contributions. In the US these are FICA taxes, Social Security (6.2%) and Medicare (1.45%). In the UK it is National Insurance. They fund pensions, healthcare and benefits.
- Pre-tax deductions. Pension or 401(k) contributions, and some benefits, come out before tax is calculated, which lowers your taxable income.
A real example
Take a single person in the US earning $75,000 a year (2025 rules). After the standard deduction, federal income tax, Social Security and Medicare, their take-home pay is about $61,150, before any state tax. Here is how the gross splits:
That is roughly 81% landing in the bank. Add state income tax, which varies a lot and some states have none, and the figure shifts again.
Why tax bands matter (and why a raise is always worth it)
A common myth is that earning more can push you into a higher bracket and leave you worse off. It does not work that way. Tax is marginal: each band's rate applies only to the income within that band.
If the 22% band starts at $48,475, only the dollars above $48,475 are taxed at 22%. Everything below is still taxed at the lower rates. A raise is always a net gain, you simply keep a slightly smaller share of the portion in the top band.
Marginal vs effective rate
Because of banding, there are two "tax rates" worth knowing:
| Term | What it means | For our $75k example |
|---|---|---|
| Marginal rate | The rate on your last dollar earned | 22% |
| Effective rate | The average rate across all income | ~18.5% |
Your effective rate is the honest measure of what you actually pay, and it is always lower than your marginal rate. People often quote their marginal rate and assume it applies to everything, which overstates their real tax bill.
How to estimate your own take-home pay
- Start with your gross salary.
- Subtract any pre-tax contributions (pension, 401(k), some benefits).
- Apply income tax by band, then social contributions.
- Remember state or regional taxes if they apply where you live.

The bottom line
Your salary is the headline; your take-home pay is the reality your budget runs on. Once you understand banding, FICA or National Insurance, and the difference between marginal and effective rates, your payslip stops being a mystery, and a pay rise always leaves you better off.
Frequently asked questions
What is the difference between gross and net pay?
Gross pay is your total salary before any deductions. Net pay, or take-home pay, is what remains after income tax, social contributions (FICA or National Insurance) and any pre-tax deductions like pensions.
Does a pay rise ever reduce take-home pay?
Almost never. Because tax is charged in bands, only the income above each threshold is taxed at the higher rate. The rest of your income is unaffected, so you always keep more of a raise than you lose.
What is the difference between marginal and effective tax rate?
Your marginal rate is the rate applied to your last dollar or pound earned. Your effective rate is the average across all your income, and it is always lower because lower bands are taxed less.
