Effective Tax Rate Calculator

Effective tax rate = Total tax paid / Total gross income × 100. For a single filer earning $90,000 in 2026 with the standard deduction of $15,700: taxable income = $74,300.

Tax calculation:

• 10% on first $11,600 = $1,160
• 12% on $11,601-$47,150 = $4,266
• 22% on $47,151-$74,300 = $5,973

Total federal tax = $11,399. Effective rate = $11,399 / $90,000 = 12.7%.

The marginal rate is 22% (the rate on the last dollar earned), but the effective rate is 9.3 percentage points lower because most income is taxed at 10% and 12%.

Adding FICA taxes (7.65%) brings the total effective rate to approximately 20.3%, which is what the taxpayer actually loses to federal taxes from each paycheck when including Social Security and Medicare.

Several mechanisms reduce effective tax rates below marginal rates.

• The standard deduction ($15,700 single, $31,400 married in 2026) shields income from any taxation.
• Retirement contributions (401k up to $23,000, IRA up to $7,000) reduce taxable income at your marginal rate — a $23,000 401k contribution in the 22% bracket saves $5,060 in taxes, reducing the effective rate by approximately 5-6 percentage points.
• Tax credits directly reduce tax liability dollar-for-dollar: the Child Tax Credit ($2,000 per qualifying child) and Earned Income Tax Credit (up to $7,830 for families) can bring effective rates near zero or negative for lower-income households.
• Long-term capital gains taxed at 0-20% rather than ordinary income rates also lower the blended effective rate for investors.

Effective federal income tax rates by income (2026, single filer with standard deduction):

• $30,000 income ≈ 4.8% effective rate
• $50,000 ≈ 9.0%
• $75,000 ≈ 12.0%
• $100,000 ≈ 15.4%
• $150,000 ≈ 18.5%
• $250,000 ≈ 22.5%
• $500,000 ≈ 28.8%
• $1,000,000 ≈ 32.1%

These rates are pre-credit and assume only the standard deduction — actual effective rates are typically 2-5 percentage points lower after credits and itemized deductions.

Including state income tax (0-13.3%), FICA (7.65%), and sales tax, the total effective tax burden ranges from 20-25% for middle-income earners to 40-45% for high earners in high-tax states.

By comparison, the average effective federal rate for all US taxpayers is approximately 13.6%.

Effective tax rate is the total tax you pay divided by your total gross income, expressed as a percentage. It answers one plain question: of every dollar you earned, how many cents went to taxes?

Unlike the marginal rate — the rate applied only to your last dollar of income — the effective rate blends every bracket, deduction, and credit into a single number.

The formula has three parts:

• Total tax — federal, state, local, and optionally FICA combined
• Gross income — everything you earned before deductions
• The ratio — total tax divided by gross income, times 100

Because the Internal Revenue Service (IRS) uses a progressive bracket structure, lower portions of your income are always taxed at lower rates. That is why the effective rate sits below the marginal rate for nearly every taxpayer.

To use this calculator, enter your gross income and each tax you actually paid, then read the effective rate shown at the top. The tool divides your combined tax by gross income automatically.

Follow these steps:

• Enter total gross income — the amount before any deductions, found on your pay stub or Form W-2
• Enter federal income tax from the tax line of your Form 1040, not your withholding
• Add state and local income tax from your state return
• Enter FICA (Social Security plus Medicare) and check the include box

Worked example: on $80,000 gross income with $9,000 federal, $3,000 state, and $6,120 FICA, total tax is $18,120 and your effective rate is 22.7%.

Using the final tax figure from your filed return — rather than paycheck withholding — gives the most accurate result.

Use your marginal rate for decisions about the next dollar, and your effective rate to understand your overall burden. They answer different questions.

Your marginal rate is the bracket your highest dollar falls into. It tells you how much tax a raise, a bonus, or an extra 401(k) contribution will change.

Your effective rate is total tax over total income. It reveals what share of everything you earned actually left for taxes — the right figure for budgeting and comparing years.

• Deciding whether to fund a traditional IRA? Use marginal.
• Estimating annual take-home for a budget? Use effective.
• Comparing your burden with someone in another state? Use effective.

The IRS republishes bracket thresholds each year, so confirm the current-year figures before running any marginal-rate math.

FICA payroll taxes add a nearly flat layer on top of income tax that many people forget when estimating their effective rate. Under the Federal Insurance Contributions Act, employees pay 6.2% for Social Security and 1.45% for Medicare — 7.65% total — matched by the employer.

The Social Security Administration caps the 6.2% Social Security portion at an annual wage base that the SSA adjusts each year, so high earners stop paying that tax above the ceiling. Medicare's 1.45% has no cap, and an Additional Medicare Tax of 0.9% applies above a threshold set by the IRS.

• Employees pay 7.65% up to the wage base
• Self-employed pay both halves — 15.3%
• High earners owe an extra 0.9% Medicare above the IRS threshold

Because FICA is essentially flat, it raises the effective rate most for middle-income workers.

State and local income taxes can swing your effective rate by more than ten percentage points depending on where you live. They stack directly on top of your federal tax.

Nine states — including Texas, Florida, Nevada, and Washington — levy no broad personal income tax, while others use progressive schedules that reach into the double digits at the top. Some cities add a local income tax on top of the state rate.

• No-income-tax states often offset with higher property or sales taxes
• Progressive-state residents pay a rising rate as income climbs
• Local taxes in certain metro areas add another point or two

Because state rules change frequently, confirm your current rate with your state's department of revenue rather than assuming last year's number still applies. The IRS treats state and local income tax as separate from federal liability.

Self-employed workers usually face a higher effective rate than employees because they pay both halves of FICA. Instead of 7.65%, they owe 15.3% self-employment tax — 12.4% Social Security up to the SSA wage base plus 2.9% Medicare — reported on Schedule SE.

The IRS lets you deduct half of the self-employment tax when figuring adjusted gross income, which softens the impact, and legitimate business expenses reduce net earnings before the tax applies.

• Deduct business expenses to lower net self-employment income
• Deduct one-half of self-employment tax above the line
• Contribute to a SEP-IRA or Solo 401(k) to cut taxable income further

Because no employer withholds for you, make quarterly estimated payments to the IRS to avoid an underpayment penalty at year end.

The most common mistake is dividing tax by taxable income instead of gross income, which inflates your effective rate. The denominator should always be total income before deductions.

Watch for these errors:

• Using withholding instead of actual tax — paycheck withholding is only an estimate; use the tax line from your filed Form 1040
• Forgetting FICA — leaving out the 7.65% payroll tax understates your true burden
• Confusing effective with marginal — quoting your bracket as if it were your real rate
• Ignoring state and local tax — a federal-only rate misses a large slice
• Mixing tax years — pairing this year's income with last year's tax paid

The Consumer Financial Protection Bureau recommends budgeting from your actual filed returns. Confirm that both the numerator and denominator come from the same tax year.

Your effective tax rate is the single best number for building a realistic household budget, because it reflects what you actually keep. Take-home pay equals gross income minus total tax.

If your combined effective rate — federal, state, local, and FICA — is 25%, then roughly 75 cents of every earned dollar is available for spending, saving, and paying down debt.

• Estimate monthly net by applying your effective rate to gross pay
• Set savings targets against take-home, not gross
• Revisit after life changes — a raise, marriage, or a move shifts the rate

The Consumer Financial Protection Bureau suggests budgeting from net income to avoid overcommitting. Because withholding rarely matches your final liability, reconcile against your filed return each year so your budget stays accurate.
