Almost every job offer, salary negotiation, and "how much do you make?" conversation gets framed around gross income, because it's the clean, comparable number. But gross income isn't spending money — it's the starting point before payroll runs a series of subtractions. Understanding the gap between the two is one of the most common sources of budgeting surprises for first-time earners.
What Gets Subtracted Along the Way
Between gross and net, a paycheck typically passes through several layers of deductions:
- Federal income tax — withheld based on your W-4 elections and tax bracket
- State and local income tax — varies by state; some states have none
- FICA taxes — 6.2% Social Security + 1.45% Medicare, fixed regardless of bracket
- Pre-tax benefits — 401(k) contributions, health/dental/vision premiums, HSA/FSA
- Post-tax deductions — Roth 401(k), life insurance, wage garnishments
Worked Example
Consider a single filer earning a $75,000/year salary, contributing 6% to a traditional 401(k), and paying $200/month for health insurance:
| Item | Annual Amount |
|---|
| Gross income | $75,000 |
| 401(k) contribution (6%, pre-tax) | −$4,500 |
| Health insurance (pre-tax) | −$2,400 |
| Federal income tax (est.) | −$7,100 |
| State income tax (est., 5%) | −$3,050 |
| FICA (7.65% of gross) | −$5,738 |
| Net (take-home) income | ≈ $52,212 |
That's roughly 70% of gross ending up as actual take-home pay — a common range for a mid-income earner in a state with income tax.
💡 Pro Tip: When comparing job offers or negotiating a raise, always convert to net income impact. A $5,000 raise rarely means $5,000 more in your pocket — after taxes and any percentage-based 401(k) match, it's often closer to $3,300-$3,700.

Frequently Asked Questions
What is the difference between gross and net income?
Gross income is your total earnings before any deductions. Net income is what's left after taxes, FICA, health insurance, and retirement contributions are withheld — the amount actually deposited into your bank account.
How much less is net income than gross income typically?
For most U.S. employees, net pay lands around 70-80% of gross pay, though it varies widely based on state income tax, filing status, benefit elections, and retirement contribution rates.
Which figure should I use to build a budget?
Always budget from net income. Gross income overstates what you actually have available to spend, since taxes and deductions are withheld before the money ever reaches you.
Do lenders use gross or net income to qualify me for a loan?
Most lenders, including mortgage underwriters, use gross income to calculate your debt-to-income ratio, since it standardizes comparisons across borrowers with different tax situations and benefit elections.
Is gross income the same as taxable income?
Not exactly. Taxable income is gross income minus pre-tax deductions (like 401(k) contributions or health insurance premiums) and either the standard or itemized deduction — it's the base the IRS actually applies tax brackets to.
What about gross vs net income for a business?
For a business, gross income (or gross profit) is revenue minus cost of goods sold, while net income is what remains after all operating expenses, interest, and taxes — the true bottom-line profit.
