Does this include deductions?

No. Enter taxable income after deductions and credits.

Are state taxes included?

No. This tool focuses on US federal tax brackets only.

Will a raise push all my income into a higher tax rate?

No. In a progressive system like the US, only the portion of your income above each bracket threshold is taxed at the higher rate. Your lower slices of income still benefit from the lower bracket rates. The calculator illustrates this by showing total tax, effective rate, and marginal rate separately.

Can I use this to file my taxes?

No. This is a high-level estimator based on 2024 brackets and does not account for all the rules that apply on a real return, such as various credits, AMT, phaseouts, or different types of income. Use official IRS forms, certified software, or a tax professional to prepare and file your return.

What income should I enter if I only know my gross pay?

Estimate taxable income by starting with gross income, subtracting pre‑tax contributions and deductions, then subtracting your standard or itemized deduction. The result is a better input for this calculator than gross pay.

Does this include capital gains tax rates?

No. This estimator applies ordinary income tax brackets only. Qualified dividends and long‑term capital gains are taxed under different schedules and should be analyzed separately.

Why is my effective rate much lower than my marginal rate?

Because only the highest slice of your income is taxed at your marginal rate. Lower portions are taxed at lower rates, which pulls the overall average (effective) rate down.

Can I use this for quarterly estimated tax planning?

It can help you estimate an annual tax total, but estimated taxes depend on payment timing, safe harbor rules, and other factors. Use IRS guidance or a professional for compliance decisions.

Marginal rate: 22.00%

Overview

US federal income tax is progressive: different slices of your taxable income are taxed at different rates. Your “tax bracket” refers to the rate applied to your last dollar of income, while your effective rate is the overall percentage you actually pay.

This tax bracket estimator applies the 2024 IRS tax brackets for single and married filing jointly filers to a taxable income amount you provide. It shows an approximate total federal tax, your effective tax rate, and your marginal rate so you can see where you sit in the bracket structure.

Because it works with taxable income (not gross income), this tool is best used after you’ve already estimated deductions and adjustments. That makes it a useful “second step” for planning: once you have a rough taxable income number, you can see how much federal income tax that number implies and how close you are to the next bracket.

Use it for quick scenario checks—raises, bonuses, extra income, or changes in pre‑tax contributions—without running a full tax return. The results are simplified, but they provide a helpful baseline for discussions with a tax professional or for building a more detailed spreadsheet model.

How to use this calculator

Enter your taxable income, which is your income after deductions and adjustments as it would appear on your Form 1040 taxable income line.
Select your filing status (Single or Married Filing Jointly) so we can use the correct 2024 bracket thresholds.
The calculator applies each tax rate to the portion of your income that falls into that bracket and sums the results to estimate total federal income tax.
It then divides total tax by taxable income to compute your effective tax rate.
Finally, it determines your marginal rate by identifying the bracket that your last dollar of income falls into.
Review the outputs and try different income values (for example, with and without a raise or bonus) to see how your marginal and effective rates change.

Inputs explained

Taxable income: Your income after deductions and adjustments, as shown on your Form 1040 taxable income line. This is not gross or AGI; it’s the amount subject to ordinary federal income tax brackets.
Filing status: Choose Single or Married Filing Jointly to apply the appropriate 2024 federal tax bracket thresholds. Other filing statuses are not modeled in this simple version.

Outputs explained

Estimated tax: An estimate of your total US federal income tax on ordinary income based on 2024 brackets for your filing status, before nonrefundable and refundable credits such as CTC or EIC.
Effective tax rate: Total estimated tax divided by taxable income, expressed as a percentage. This represents your overall average tax rate across all brackets.
Marginal rate: The tax rate applied to your last dollar of taxable income—the bracket you are currently in. This rate is often the one you use for planning decisions like Roth vs traditional contributions.

How it works

We apply 2024 IRS tax brackets for single or married filing jointly statuses, summing the tax owed at each bracket.

The calculator slices your taxable income into bracket ranges and applies each bracket’s rate only to the portion of income that falls within that range.

We then sum the tax owed across all slices to estimate your total federal income tax on ordinary taxable income.

Effective rate = total tax ÷ taxable income. This shows the blended average rate across all brackets you touch.

Marginal rate is the bracket rate that applies to your last dollar of taxable income; it is the rate most relevant for decisions about additional income or deductions.

Because this tool uses taxable income, it assumes you have already accounted for deductions and adjustments. If you only know gross income, estimate taxable income first or use a paycheck calculator to approximate it.

Formula

We apply a piecewise tax calculation using 2024 IRS brackets.

For each bracket:
Tax on bracket slice = (Income in bracket range) × Bracket rate
Total tax = Sum of tax on all slices up to your taxable income

Effective rate = Total tax ÷ Taxable income
Marginal rate = Tax rate of the highest bracket reached by your taxable income

When to use it

Estimating taxes on a raise, bonus, or freelance income.
Understanding where your next dollar of income will be taxed.
Planning Roth vs traditional contributions by looking at marginal rates.
Exploring how changing your deductible contributions (like 401(k), HSA, or traditional IRA) could move you between brackets by lowering taxable income.
Comparing the impact of filing jointly versus individually on combined taxable income and bracket thresholds when planning as a couple.
Providing a quick reference during financial planning sessions when you need an approximate bracket snapshot without running a full tax return.
Testing how a large capital gain or stock sale would affect your marginal rate on ordinary income (while remembering that capital gains have their own rates).
Estimating the tax impact of a one‑time income event like a bonus, severance, or relocation payment before you decide on withholding or estimated payments.

Tips & cautions

Use taxable income, not gross salary—deductions and pre-tax contributions reduce the number you enter.
Try multiple income amounts to see when you cross into a higher marginal bracket.
State/local taxes are separate; add them manually if you need a combined view.
If you are comparing scenarios, keep deductions constant so you can isolate the impact of the income change itself.
Use the marginal rate for decisions about additional income or deductions; use the effective rate for budgeting your overall tax bill.
If you receive variable income (bonuses, commissions, RSUs), consider running a conservative scenario with higher taxable income to avoid underestimating tax.
For joint filers, remember that uneven income between spouses can change how much of your income falls into each bracket.
Uses static 2024 US federal brackets; laws change and other filing statuses are not included here.
Does not model credits, AMT, or phaseouts that can change effective rates.
Outputs are estimates; real returns depend on your full tax situation.
Does not distinguish between different types of income such as qualified dividends, long-term capital gains, or net investment income, which may be taxed at different rates than ordinary income.
Does not include additional Medicare taxes, Net Investment Income Tax, or other surtaxes that may apply at higher income levels.
Assumes all taxable income is subject to the same bracket schedule; special rules for trusts, estates, and other entities are not modeled.
Does not include standard or itemized deductions—those must be reflected in the taxable income you enter.

Worked examples

$95k income, single filer

Tax ≈ $17,400
Effective rate ≈ 18.3%
Marginal rate = 24%

$150k income, married filing jointly

Tax ≈ $21,000
Effective rate ≈ 14%
Marginal rate = 22%

Comparing a bonus: $95k vs $105k, single filer

At $95,000 taxable income, marginal rate might be 24% with a certain total tax and effective rate.
At $105,000, total tax increases but only the income above the bracket threshold is taxed at the higher rate.
This shows that receiving a bonus does not retroactively tax all your income at the highest bracket—it only affects the top slice.

Effect of pre-tax contributions on taxable income

Start with a projected taxable income of $90,000 as a single filer.
Consider adding $5,000 more to pre-tax retirement contributions, which could reduce taxable income to about $85,000 (assuming other items unchanged).
Run the calculator with $90,000 and $85,000 to see how total tax and effective rate change, highlighting the potential tax benefit of contributing more pre-tax.

Comparing Single vs Married Filing Jointly on the same combined income

Assume a couple with a combined taxable income of $120,000 considers their bracket as Single versus Married Filing Jointly.
Run the calculator once at $120,000 with filing status Single and once as Married Filing Jointly.
Compare the total tax and effective rates to see how joint filing can change bracket thresholds and overall effective tax rates.

Testing a higher-income scenario

Assume taxable income increases from $180,000 to $200,000 for a married couple.
Run both values to see how only the top slice is taxed at the higher marginal rate.
Use the effective rate to estimate total tax for budgeting and withholding adjustments.

Deep dive

Estimate US federal tax owed plus effective and marginal rates using current brackets for single or married filers.

Great for planning bonuses, side income, or contribution strategies when you want a quick bracket check.

The estimator breaks taxable income into bracket slices and applies rates to each slice, so you can see the difference between marginal and effective tax rates.

Use it as a planning tool when adjusting retirement contributions, evaluating a raise, or estimating how a one‑time income event affects your federal tax bill.

Because it focuses on taxable income rather than gross income, it works best after you have estimated deductions, adjustments, and pre‑tax contributions.

If you want a deeper projection, use this result as a baseline and then layer in credits, deductions, and special income types with a full tax planner.
