Marginal vs. Effective Tax Rate: The 30-Second Answer

Two numbers describe how much federal income tax you pay, and people mix them up constantly.

Your marginal tax rate is the rate on your last dollar of income. It’s the bracket your top dollar lands in. For a single filer earning $85,000 in 2026, that’s 22%.

Your effective tax rate is the average rate across all your income. It blends together every bracket your money passes through. For that same $85,000 earner, the effective federal rate is closer to 11.6%.

Both numbers are correct. They just answer different questions. The effective rate tells you what you actually paid overall. The marginal rate tells you what the next dollar, the next raise, or the next bonus will be taxed at. Knowing which is which is the difference between budgeting accurately and turning down money you should take.

How the US Progressive Bracket System Actually Works

The United States uses a progressive tax system. That word causes most of the confusion, so here’s what it really means: your income is taxed in slices, not all at one rate.

There are seven federal tax brackets, running from 10% up to 37%. As your income climbs, each slice that falls into a higher bracket gets taxed at that bracket’s rate. The slices below it keep their lower rates. Nothing reaches back and re-taxes income you already earned.

Here are the 2026 federal tax brackets for a single filer:

10% on income from $0 to $12,400
12% on income from $12,401 to $50,400
22% on income from $50,401 to $105,700
24% on income from $105,701 to $201,775
32% on income from $201,776 to $256,225
35% on income from $256,226 to $640,600
37% on income above $640,600

For 2026, the bracket thresholds rose about 2.7% on average from inflation adjustments, and the top rate stays 37%. One detail matters here: these brackets apply to your taxable income, which is your gross pay minus deductions, not your full salary. Most workers take the standard deduction, which for 2026 is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for head of household.

Worked Example: An $85,000 Single Filer in 2026

Numbers make this concrete. Take a single person earning $85,000 in gross salary for 2026, taking the standard deduction.

First, subtract the deduction. $85,000 minus $16,100 leaves $68,900 in taxable income, and that’s the figure the brackets apply to.

Now tax it in slices:

10% bracket: 10% of $12,400 = $1,240.00
12% bracket: 12% of $38,000 (the income from $12,401 to $50,400) = $4,560.00
22% bracket: 22% of $18,500 (the income from $50,401 to $68,900) = $4,070.00
Total federal income tax: $9,870.00

Notice that only $18,500 of this person’s income gets taxed at 22%. The rest is taxed at 10% and 12%.

Now the two rates.

The marginal rate is 22%, because the last dollar of taxable income landed in the 22% bracket.

The effective rate depends on the denominator you choose:

Effective rate on taxable income: $9,870 / $68,900 = 14.3%
Effective rate on gross income: $9,870 / $85,000 = 11.6%

Tax professionals usually quote the effective rate against taxable income. But if you think in terms of your paycheck and your full salary, the gross-income version (11.6%) is the more intuitive figure. Both are valid. Just label which one you mean.

One more thing this example leaves out: it’s federal income tax only. FICA adds another 7.65% (6.2% Social Security plus 1.45% Medicare), and most states add their own income tax on top. Your all-in effective rate, the share of your paycheck that actually leaves you, is meaningfully higher than 11.6%.

The Bracket Myth: Does a Raise Really Cost You Money?

Here’s the misconception that refuses to die: “I turned down a raise because it would bump me into a higher bracket and I’d take home less.”

That’s not how it works. Ever.

When a raise pushes part of your income into a higher bracket, only the new dollars above the threshold are taxed at the higher rate. Everything below stays exactly where it was. A raise always leaves you with more take-home pay, never less.

Run the numbers on our $85,000 earner getting a $5,000 raise to $90,000. Taxable income rises from $68,900 to $73,900. All $5,000 of the new income sits in the 22% bracket, so the extra federal tax is 22% of $5,000, or $1,100. After FICA of about $382 on the new income, this person still pockets roughly $3,518 more per year. The raise was clearly worth taking.

There is one real exception, and it has nothing to do with brackets. Some income-based credits and benefits phase out as you earn more, such as certain healthcare subsidies, the Saver’s Credit, or student loan repayment thresholds. Crossing one of those phase-out points can claw back value. But that’s a separate mechanism from the tax brackets, and it affects far fewer people than the bracket myth suggests. The brackets themselves never punish a raise.

Which Rate Shows Up on Your Paycheck, and Which One to Use

Your pay stub shows a federal income tax withholding line every period. Which rate does it reflect?

For regular paychecks, withholding is designed to roughly track your effective rate over the year. Payroll systems annualize your salary, apply the brackets and your W-4 settings, and spread the resulting tax evenly across pay periods. That’s why your withholding rate feels lower than your bracket. It’s the average, not the top slice, and it’s the number to use when you budget.

For raises, bonuses, and overtime, think in terms of your marginal rate. Those dollars stack on top of income you already earned, so they’re taxed at your highest bracket. When you decide whether extra hours or a side project are worth it, the marginal rate is the honest number to plan around.

Bonuses deserve a special note, because their paychecks often look alarming. Employers commonly use the percentage method, withholding a flat 22% on bonuses under $1 million. Others use the aggregate method, folding the bonus into a regular paycheck and withholding as if that amount were your normal pay, which can push the withholding rate even higher for a single check. Either way, that’s withholding, not your final tax. When you file your return, your bonus is taxed at your actual marginal rate, and any over-withholding comes back as a refund. The bonus tax calculator can show the difference between the two methods for your numbers.

See Both Rates for Your Situation

The cleanest way to stop guessing is to see both rates for your real salary, in your real state.

Pay44 is a US paycheck calculator that breaks down take-home pay with federal and state-by-state detail for all 50 states. It surfaces your effective and marginal tax rates side by side, so you can see what you paid overall and what the next dollar will cost. The simulate feature lets you preview a raise before you accept it, turning the bracket myth into actual numbers, and you can download the app to run scenarios on your phone.

Because state income tax and FICA stack on top of federal, the rate that matters most is your all-in effective rate, not the federal figure alone. A worker in a no-income-tax state and a worker in a high-tax state can earn identical salaries and keep very different amounts. A full federal plus state breakdown is the only way to see your true take-home pay. Browse the paycheck tools or read more on the Pay44 blog to keep digging.

Frequently Asked Questions

What is the difference between marginal and effective tax rate?

Marginal is the rate on your last dollar earned, which is your top tax bracket. Effective is the average rate across all your income. Your effective rate is always lower than your marginal rate because it blends in income taxed at lower brackets.

Which tax rate shows up on my paycheck?

Your regular paycheck withholding roughly tracks your effective rate, which makes it useful for budgeting. But raises, bonuses, and overtime are taxed at your marginal rate, because those extra dollars stack on top of income you already earned.

Does earning more money push all my income into a higher tax bracket?

No. Only the dollars above a bracket threshold are taxed at the higher rate. The income below that threshold stays taxed at the lower rates. A raise never moves your entire income into a new bracket.

How do I calculate my effective tax rate?

Divide total tax (Form 1040 line 24) by taxable income (line 15). For a paycheck-focused view, you can also divide the tax you paid by your gross income. The two denominators give different numbers, so always note which one you are using.

Will a raise ever leave me with less take-home pay?

Not from tax brackets alone. You always net more money after a raise. The rare exception is losing income-based credits or benefits that phase out as your income rises, which is separate from how brackets work.

How are bonuses taxed compared to regular pay?

Employers often withhold a flat 22% on bonuses under $1 million using the percentage method, or they fold the bonus into a regular paycheck with the aggregate method. That is withholding only. Your final tax is settled at your marginal rate when you file.

Do state taxes change my effective and marginal rates?

Yes. State income tax and FICA stack on top of federal tax, so your all-in effective rate is higher than the federal figure alone. To see your real take-home picture, use a full federal plus state breakdown for your state.
