Marginal vs. Effective Tax Rate: Why "I'm in the 22% Bracket" Misleads
Updated August 23, 2026 · DollarCalcs
"I'm in the 22% bracket, so the government takes 22%." It's one of the most common money beliefs — and it's wrong in a way that causes real mistakes, from refusing raises to overestimating the cost of overtime.
Your marginal rate is the tax on your next dollar. Your effective rate is total tax divided by total income — always lower, because the U.S. system is progressive: every filer's income fills the low brackets first.
A single filer earning $75,000 in 2026
First, the $16,100 standard deduction comes off the top, leaving $58,900 of taxable income. The first $12,400 of that is taxed at 10%, the next slice up to $50,400 at 12%, and only the remainder at 22%. Total federal income tax: $7,670. That's an effective federal rate of 10.2% — while the marginal rate is 22%.
Add FICA (7.65% on wages) and the effective all-in federal rate is 17.9%. Still nowhere near "22% of everything."
No, a raise can't put you "in a higher bracket" and cost you money
Because brackets are marginal, only the dollars above each threshold are taxed at the higher rate. A raise from $75,000 to $80,000 adds $5,000 of income taxed at 22% federally — you keep about $3,500 of it after federal tax and FICA, more or less depending on your state. Your previously earned dollars are taxed exactly as before.
The rare genuine cliffs are benefit phase-outs, not brackets: certain credits, subsidies and income-tested programs can drop sharply at specific income lines. Those are worth checking individually, but the tax brackets themselves never take back a raise.
Why the distinction matters
Effective rate is the number for budgeting ("how much of my income goes to tax"), and marginal rate is the number for decisions ("what does one more dollar of 401(k) contribution save me"). A traditional 401(k) contribution at a 22% marginal rate saves 22 cents of federal tax per dollar — which is exactly why pre-tax contributions cost less than their face value in take-home pay. See your own split in the paycheck calculator, which reports your effective rate on the receipt.

Frequently asked questions
+What's my effective tax rate on $75,000?
Federal income tax only: about 10.2% in 2026 for a single filer with the standard deduction. Including Social Security and Medicare: about 17.9%, before state tax.
+Does overtime get taxed at a higher rate?
Overtime is withheld at a higher rate on that check because payroll systems annualize each paycheck, but it's taxed at your normal marginal rate when you file. Heavy-overtime checks often generate refunds at tax time.
+Which rate do I use to value a 401(k) contribution?
Marginal. Each pre-tax dollar avoids tax at your top rate (federal plus state where applicable), so a $1,000 traditional contribution at 22% federal + 5% state costs about $730 of take-home.
