Marginal Tax Rate Calculator

Marginal Tax Rate Calculator

Your marginal rate is the tax on your last dollar of income—important for financial decisions.

How It Works

1. Enter your income or relevant financial details 2. Select your filing status and applicable deductions 3. Review your estimated tax liability 4. Plan your finances accordingly

Important Notes

• Tax laws change frequently; verify rates for the current year
• This provides estimates; consult a tax professional for complex situations
• State and local taxes vary and may require separate calculations
• Consider tax-advantaged strategies to minimize your liability

Common Deductions and Credits

Many taxpayers can reduce taxes through:

• Standard deduction or itemized deductions
• Retirement account contributions
• Education credits
• Child tax credit
• Mortgage interest deduction

Marginal vs Effective Rate

These two numbers answer different questions and get confused constantly.

Marginal rate — what the *next* dollar is taxed at. Use it for decisions: should I contribute to a 401(k), take the overtime, realise this gain?

Effective rate — total tax ÷ total income. Use it for budgeting and for comparing years.

On $100,000 taxable, single: marginal 22%, effective 17.1%.

The marginal rate is not always the bracket rate, either. Phase-outs create higher effective marginal rates in specific bands — the student loan interest deduction, the Saver's Credit, ACA premium subsidies and Social Security taxation all phase out over income ranges, and inside those ranges each extra dollar can cost far more than the bracket suggests.

A Note on These Figures

Brackets, thresholds and the standard deduction shown here are for tax year 2024, filed in 2025, and they are indexed to inflation every year. State tax is not included and ranges from nothing at all (Florida, Texas, Washington and six others) to 13.3% in California.

This is an estimate, not tax advice. Anything involving equity compensation, multiple states, self-employment or a life change is worth an hour of a professional's time.

Worked Through the Brackets

On $95,000 of gross income, filing single, taking the $14,600 standard deduction — so $80,400 of taxable income:

Bracket	Range	Income taxed here	Tax
10%	$0 – $11,600	$11,600	$1,160
12%	$11,600 – $47,150	$35,550	$4,266
22%	$47,150 – $100,525	$33,250	$7,315
Total			$12,741

That is a 13.4% effective rate against a 22% marginal rate. The two answer different questions: the marginal rate is what the next dollar costs, and it is the one that decides whether a 401(k) contribution or an extra shift is worth it. The effective rate is what you actually paid, and it is the one to budget against.

The Same Income, Different Sources

Source	Federal tax on it
Wages (above)	$12,741
Self-employment profit	$12,741 income tax plus $13,423 SE tax
Long-term capital gain of $10,000	$1,500 at 15%

Where income comes from changes the bill more than how much of it there is. A self-employed filer at this level pays roughly $13,423 that an employee never sees, because there is no employer paying the other half of FICA.
