How marginal tax brackets actually work
The single biggest misunderstanding about U.S. income tax is the idea that earning more can shrink your paycheck by pushing "all" your income into a higher bracket. That's not how it works. The federal system is progressive and marginal: each bracket only taxes the slice of income that falls within it. If you're single and earn $60,000 in taxable income, you don't pay 22% on all $60,000 — you pay 10% on the first $12,400, 12% on the next chunk up to $50,400, and 22% only on the remaining amount above that. Enter your own numbers above to see this broken out line by line.

Why your effective rate is always lower than your bracket
Because every dollar under your top bracket is taxed at the lower rates that apply to it, your effective (average) tax rate is always lower than your marginal (top) rate — often by a wide margin. Someone with $150,000 in taxable income might have a 24% marginal rate but an effective rate closer to 18%, since a large share of that income was taxed at 10%, 12%, and 22% before any of it reached the 24% bracket.
A raise or bonus that pushes you into a new bracket never reduces your take-home pay overall — it only means the additional income above the threshold is taxed at the new, higher rate. The income you already earned below that threshold keeps its original (lower) tax treatment.
