Gross vs. Net Salary: Why Your Paycheck Is Smaller Than Your Offer Letter

A $70,000 job offer doesn't mean $70,000 lands in your bank account — the gap between gross and net salary is where taxes and deductions quietly take a meaningful share before you ever see the money.

Gross Salary Is the Headline Number

Gross salary is your total compensation before any deductions — the number in your offer letter, employment contract, or job posting. It's useful for comparing job offers and calculating things like loan eligibility, but it's not what actually hits your bank account each pay period.

Net Salary (Take-Home Pay) Is What You Actually Receive

Net salary is what remains after all mandatory and voluntary deductions: income tax, payroll taxes (like Social Security and Medicare in the US, or National Insurance in the UK), retirement contributions, and health insurance premiums. Depending on your tax bracket, location, and benefit elections, net pay is commonly 65-80% of gross pay — meaning a fifth to a third of your headline salary disappears before it reaches you.

What's Actually Being Deducted

The biggest deduction for most employees is income tax, which scales progressively with income. Next are mandatory payroll/social insurance taxes, which fund programs like Social Security, Medicare, or their equivalents elsewhere. Then come voluntary-but-common deductions: retirement plan contributions (401(k), pension), health insurance premiums, and other pre-tax benefits like flexible spending accounts. Pre-tax deductions (retirement contributions, some health premiums) actually reduce your taxable income, which is why maximizing them can sometimes increase your effective net pay percentage even while more money is being withheld.

Working the $70,000 Example

Take that $70,000 offer from the opening line — a single US filer contributing 6% to a 401(k), using the 2026 IRS standard deduction and tax brackets. Here's roughly where the money actually goes:

• 401(k) contribution (6%, pre-tax): $4,200
• Federal income tax (on taxable income after the 401(k) and standard deduction): roughly $5,925
• FICA (Social Security + Medicare, 7.65% of gross): roughly $5,355
• State income tax (at a representative 5% flat rate — this varies enormously by state, from 0% to over 13%): roughly $3,290

That's about $18,770 in total deductions and contributions, leaving roughly $51,230 in actual take-home pay — about 73% of the original $70,000 headline figure, squarely in the 65-80% range this guide opened with. Notice that nearly a third of the total deduction here (the 401(k) piece) isn't lost at all — it's still your money, just moved into a retirement account instead of your checking account, which is exactly why gross-vs-net isn't simply "good number vs. bad number."

Why This Matters When Comparing Job Offers

Two offers with the same gross salary can produce very different net pay if one has better benefits (employer covers more of your health premium) or if they're in different tax jurisdictions (state/province/country income tax rates vary significantly). Always compare net, take-home-equivalent figures when evaluating offers involving different locations or benefit packages — the gross number alone can be misleading.

Budgeting Off Gross Salary Is a Common, Costly Mistake

Building a budget or mortgage affordability estimate off your gross salary rather than your actual net pay is one of the most common financial planning errors — it overstates what you can actually afford by the entire margin of tax and deductions, sometimes 25-35% of the headline number.
