How do I calculate my tax bracket?

Your tax bracket is determined by your taxable income (gross income minus deductions). For 2025, the brackets for single filers are: 10% on income up to $11,925, 12% on $11,926-$48,475, 22% on $48,476-$103,350, 24% on $103,351-$197,300, 32% on $197,301-$250,525, 35% on $250,526-$626,350, and 37% on income over $626,350. Your marginal rate is the bracket your last dollar falls in; your effective rate is usually much lower.

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the rate on your last dollar of income — the bracket you 'fall into.' Your effective tax rate is the actual percentage of your total income paid in taxes. Someone in the 24% bracket may have an effective rate of only 14-17% because lower portions of income are taxed at lower rates. The effective rate is what actually matters for your budget.

How much tax will I pay on $100,000?

A single filer earning $100,000 with the standard deduction ($15,000 in 2025) has $85,000 in taxable income. Federal tax: $11,788. Effective rate: 11.8%. Marginal bracket: 22%. Add state taxes (0-13% depending on state) and FICA (7.65%) for total tax burden.

Marginal vs Effective Rate: Why It Matters

Common Misconception

“If I earn $1 more and move into the 22% bracket, all my income gets taxed at 22%.”

This is wrong. Only the income within each bracket is taxed at that rate.

Taxable Income: $60,000 (Single)	Income in Bracket	Tax Rate	Tax
First $11,925	$11,925	10%	$1,193
$11,926 – $48,475	$36,550	12%	$4,386
$48,476 – $60,000	$11,525	22%	$2,536
Total	$60,000		$8,115
Effective rate			13.5%

Your marginal rate is 22%, but your effective rate is only 13.5%. You never “lose money” by earning more.
