Gross pay is the total amount you earn before anything is taken out. Net pay is what actually lands in your bank account after taxes, insurance premiums, retirement contributions, and other deductions are subtracted. The difference between the two can be surprisingly large, often 25% to 35% of your earnings, and understanding both numbers matters for everything from budgeting to qualifying for a loan.
How Gross Pay Is Calculated
If you’re paid hourly, your gross pay is your hourly rate multiplied by the total hours you worked in the pay period, including any overtime. If you earn a salary, your gross pay for each paycheck is your annual salary divided by the number of pay periods in the year. Someone earning $60,000 a year who is paid biweekly (26 pay periods) has a gross pay of about $2,308 per paycheck.
Gross pay also includes bonuses, commissions, tips, and overtime premiums. It’s the starting number at the top of your pay stub before any line items are subtracted.
What Gets Deducted From Gross Pay
Three categories of deductions sit between gross pay and net pay: mandatory taxes, pre-tax benefits, and post-tax deductions. They come off in a specific order, and the order matters because some deductions reduce the income that gets taxed.
Pre-Tax Benefit Deductions
Certain voluntary benefits are subtracted from your pay before taxes are calculated, which lowers your taxable income. The most common pre-tax deductions include:
- Health insurance premiums: Medical, dental, and vision coverage offered through your employer is typically deducted pre-tax through what’s called a Section 125 plan.
- Traditional 401(k) contributions: Money you put into a traditional 401(k) is deferred for federal income tax (and most state income taxes), though it’s still subject to Social Security and Medicare taxes.
- HSA and FSA contributions: Health savings accounts and flexible spending accounts for healthcare or dependent care expenses come out before taxes.
These deductions shrink your taxable income, so they effectively cost you less than their face value. A $200 monthly health insurance premium might only reduce your net pay by around $140 to $160, depending on your tax bracket, because you’re not paying income tax on that $200.
Mandatory Tax Withholdings
After pre-tax deductions, your employer withholds several required taxes from what remains:
- Federal income tax: The amount depends on your filing status, income level, and the information you provided on your W-4 form. The W-4 lets you adjust withholding by claiming dependents, reporting additional income, or requesting a specific extra amount withheld each pay period.
- Social Security tax: You pay 6.2% of your wages up to the annual wage base (your employer pays a matching 6.2%). Once your earnings for the year exceed that cap, Social Security tax stops being withheld.
- Medicare tax: You pay 1.45% of all wages with no income cap. If you earn above $200,000, an additional 0.9% Medicare surtax kicks in on wages above that threshold.
- State and local taxes: Most states impose their own income tax, and some cities or counties add a local tax on top.
Social Security and Medicare together are often called FICA taxes, and they account for 7.65% of your pay right off the top. Combined with federal and state income tax, mandatory withholdings alone can take 20% to 30% or more of your gross pay.
Post-Tax Deductions
Some deductions come out after taxes have been calculated. Roth 401(k) or Roth IRA contributions are withheld on a post-tax basis, meaning you pay taxes now but won’t owe taxes on withdrawals in retirement. Supplemental life insurance beyond the basic coverage your employer provides, union dues, and wage garnishments ordered by a court are also subtracted after taxes. These reduce your take-home pay dollar for dollar.
A Paycheck Example
Suppose your gross pay for a biweekly paycheck is $2,500. Here’s a simplified breakdown of how it might shrink to net pay:
- Gross pay: $2,500
- Health insurance (pre-tax): -$120
- 401(k) contribution (6% pre-tax): -$150
- Federal income tax: -$220
- Social Security (6.2%): -$138
- Medicare (1.45%): -$32
- State income tax: -$90
- Net pay (take-home): $1,750
In this example, $750 disappeared between gross and net, a 30% reduction. Your pay stub will list every deduction line by line, so you can see exactly where each dollar goes.
Where Each Number Matters
Gross and net pay serve different purposes in your financial life, and using the wrong one in the wrong context can lead to costly miscalculations.
Lenders use your gross income when deciding how much you can borrow. Mortgage lenders, for instance, look at your debt-to-income ratio, which compares your monthly debt payments to your monthly gross income. They typically want your housing costs (mortgage payment, property taxes, and insurance) to stay at or below 25% to 28% of gross monthly income. Total debt payments, housing included, should generally fall at or below 33% to 36% of gross monthly income. Just because you qualify for a loan amount based on gross income, though, doesn’t mean those payments will feel comfortable once taxes and benefits have already taken their share.
Your personal budget should be built around net pay. That’s the money you actually have to work with for rent, groceries, savings, and everything else. If you budget based on your $60,000 salary without accounting for deductions, you’ll overshoot your real spending power by thousands of dollars a year.
Tax returns reference gross income in various forms. Your W-2 shows your total gross wages in Box 1 (though this figure is already reduced by pre-tax deductions like 401(k) contributions and health insurance). When people talk about adjusted gross income, or AGI, they mean gross income minus specific above-the-line deductions like student loan interest and traditional IRA contributions. AGI determines your eligibility for many tax credits and deductions.
How to Increase Your Net Pay
Since net pay is what you actually live on, there are a few levers you can pull to keep more of your gross earnings.
Review your W-4. If you consistently receive a large tax refund each spring, your employer is withholding more federal income tax than necessary. A big refund feels nice, but it means you’ve been giving the government an interest-free loan all year. Adjusting your W-4 can put that money back in your regular paychecks instead.
Maximize pre-tax benefits strategically. Contributing to a 401(k) lowers your net pay today, but it also lowers your taxable income, so the hit to your paycheck is smaller than the contribution amount. Similarly, if you have predictable medical or dependent care expenses, funding an FSA lets you pay for those costs with pre-tax dollars rather than after-tax dollars.
Check your benefits elections annually. During open enrollment, make sure you’re not paying for coverage you don’t need, like supplemental life insurance you signed up for years ago and forgot about, or a dental plan tier that’s more expensive than your actual dental costs warrant. Each unnecessary deduction chips away at your take-home pay every single paycheck.
