Effective Income Calculator
Your salary figure is not the money you can spend. Taxes come out first, then the amounts withheld from your pay for retirement, health cover, and anything else, and what is left is your effective income: the annual amount actually available to live on. This calculator takes the tax and deduction amounts you already know, from a pay stub or a tax return, and turns them into that spendable figure, with a monthly view and the combined burden as a percentage of gross pay.
Planning estimate only. Actual withholding depends on your W-4, state rules, and pay frequency. Confirm federal withholding with the IRS Tax Withholding Estimator.
Quick Answer
Gross income of $100,000 minus $12,000 federal tax, $4,000 state and local tax, $6,000 retirement, $3,000 health premiums, and $2,000 other deductions gives $73,000.00 per year of effective income, or $6,083.33 per month, with a combined tax-and-deduction burden of 27.0 percent of gross. That $73,000 is the pool your living expenses are paid from, not a figure net of those expenses.
Key takeaways
- Effective income equals gross income minus taxes minus deductions. Every line of the subtraction is shown, so a wrong figure can be spotted instead of hidden.
- This tool does not compute your tax. You enter the tax and deduction amounts from your pay stub or return, and it returns the spendable remainder.
- Living expenses are not deductions here. Rent, groceries, and loan payments are paid out of effective income after you receive it; do not enter them in the deduction fields.
- If taxes plus deductions equal or exceed gross income, the tool shows an error instead of a silent zero, because that combination almost always means a figure was misplaced, such as a monthly amount entered as an annual one.
- Effective income is not the same as effective gross income in real estate, which is rental income minus vacancy and credit losses. This page computes personal spendable income.

How to use the effective income calculator
Enter annual figures throughout: mixing a monthly tax figure with an annual salary is the most common error with this kind of tool, and it is the error the tool’s error message is designed to catch. Results stay hidden until you calculate, and Reset returns every field to the pre-filled example.
- Gross annual income: everything before anything is taken out. Salary plus bonuses plus freelance plus rental plus anything else, added together first.
- Federal and state tax: the income tax amounts actually paid or withheld for the year. If you do not know them, the IRS Tax Withholding Estimator can help you estimate federal withholding before you come back here.
- Retirement, health, and other deductions: amounts withheld from your pay before you see it. Social Security and Medicare withholding (FICA) belong in the tax fields, not in the deduction fields.
- Copy my results and Share results in the results box pass the summary on, and both do nothing until a result exists.
Effective income vs take-home pay: the explicit difference
Readers often treat effective income and take-home pay as the same number, and in casual conversation they are close. They are not the same tool, and this page is deliberately not a take-home-pay calculator. The difference is what each tool computes, and which question it answers.
| Question | Take-home-pay tool | This effective-income tool |
|---|---|---|
| What you enter | Salary, filing status, state, pay frequency; the tool computes the tax | Your actual tax and deduction amounts, already known |
| What it outputs | Net pay per paycheck after tax withholding | Annual and monthly spendable income after all taxes and recurring deductions |
| Voluntary deductions | Often optional or partial | Central: retirement, health, and other withholdings are full inputs |
| Best use | Checking a paycheck, comparing job offers by net pay | Budgeting: the pool that rent, food, and all other spending must fit inside |
| Living expenses | Not subtracted | Not subtracted either: they are paid out of the result |
Put concretely: a take-home-pay tool answers “what lands in my bank account each payday after tax?” This tool answers “after everything withheld all year, how much do I actually have to live on, per year and per month, and what share of my gross pay disappeared before I saw it?” If you need per-paycheck net pay computed from your salary and tax situation, use a take-home-pay tool such as the Gusto take-home pay calculator on this site. If you already know your tax and deduction totals and want the budgeting baseline they leave behind, use this page. The two tools complement each other; neither replaces the other, and this page does not duplicate take-home-pay content such as tax brackets, filing statuses, or pay-frequency tables.
One more distinction matters. In real estate, effective gross income means rental income minus vacancy and credit losses, a property metric with nothing to do with a paycheck. If you arrived here looking for that figure, this tool is not it. Here, effective income always means personal income after taxes and deductions.
The formula
The formula has three parts and no hidden steps. Taxes are federal plus state and local income tax. Deductions are retirement plus health premiums plus other withholdings. Effective income is gross minus both groups, and the burden is the total taken out divided by gross.
Deductions = retirement + health premiums + other deductions
Effective income = gross income − taxes − deductions
Monthly effective income = effective income ÷ 12
Burden = (taxes + deductions) ÷ gross income × 100
Worked example, checked against this exact tool
The tool is pre-filled with $100,000 gross, $12,000 federal tax, $4,000 state and local tax, $6,000 retirement, $3,000 health premiums, and $2,000 other deductions. Running it gives the following lines, verified against the tool itself.
A second run shows the tool’s behaviour at a different scale and confirms the monthly rounding. Gross $60,000, taxes $9,000, and deductions $6,000 give $45,000 per year, $3,750.00 per month, and a burden of 25.0 percent. A third run, gross $60,000 with taxes and deductions totalling $60,000 or more, produces the error message instead of a zero, which is the intended behaviour: a zero would look like an answer while hiding a misplaced figure.
Bonuses, freelance, and multiple income sources
If you earn from several streams, add them all into the gross income field first: salary plus bonuses plus freelance plus rental plus anything else. This keeps one clear number flowing through the rest of the calculation. The annual earned income calculator totals the streams for you if you want that step done separately, and the bonus take-home pay calculator isolates a single bonus if you want to see one bonus on its own. Freelancers use the same approach: enter total freelance revenue as gross, and put the income and self-employment tax you expect to pay in the tax fields. Estimated quarterly payments count as tax paid, so they belong in the tax fields, not in other deductions.
Watch the annual-versus-monthly trap with irregular income. A bonus received once is an annual figure and goes in whole; a monthly retainer must be multiplied by 12 before it goes in. If your result looks far too low, the first thing to check is whether a monthly figure slipped into an annual field, and the second is whether a deduction was entered twice, once as a tax and once as a deduction.
What counts as a deduction
Include anything withheld from your pay before you see it: 401(k) or pension contributions, employer health and dental premiums, HSA or FSA contributions, and union or professional dues. Social Security and Medicare withholding (FICA) belong in the tax fields, since they are taxes on wages, not voluntary withholdings. The IRS employer guide, Publication 15, is the reference for how those wage withholdings are figured.
Do not include spending that comes out of your take-home pay: rent, groceries, loan payments, subscriptions, and discretionary spending are budgeting items, not income deductions. They are paid out of effective income, and that is exactly why the effective-income figure is useful for budgeting: it is the ceiling those items must fit under. Once you have the monthly figure, the budget impact calculator can show what a change in spending does against it, and the salary raise calculator can show what a raise does to gross pay before this tool converts it into spendable income.
Why this tool flags impossible entries
Some calculators silently floor the result at zero when deductions exceed gross, which hides data-entry mistakes such as a misplaced decimal or a monthly figure entered as an annual one. This tool instead shows an error telling you the totals do not add up, so you can fix the entry rather than trust a wrong zero. Negative entries in the tax and deduction fields are clamped to zero for the same reason: a negative withholding is not a meaningful input, and silently accepting it would understate the burden. Gross income itself must be a positive number, since a zero or negative gross makes the burden percentage undefined.
None of this makes the result exact. Actual withholding depends on your W-4, state rules, and pay frequency, and a mid-year change in any of them changes the annual totals. Treat the output as a planning figure, check it against a recent pay stub by annualising the stub’s year-to-date figures, and revisit it whenever pay, withholding, or deductions change.
What competing calculators miss
Most effective-income tools in search compute the same gross-minus-taxes-minus-deductions formula, so the arithmetic is rarely the differentiator. The gaps are in what surrounds it:
- Single-number tools: one result with no line-item breakdown, no monthly view, and no burden percentage. A lone annual figure cannot be checked against a pay stub and cannot be used directly for a monthly budget.
- Silent-zero tools: when deductions exceed gross, they print zero instead of an error. A zero looks like an answer and hides the misplaced figure that caused it.
- Tax-computing tools presented as effective-income tools: these are take-home-pay tools under another name, with brackets and filing statuses doing the work. They answer a different question and they duplicate take-home-pay content instead of giving a clean budgeting baseline from known totals.
- Tools that blur living expenses into deductions: letting rent or loan payments into the deduction fields produces a figure that is neither take-home pay nor spendable income, and it cannot be compared with anything else. Keeping expenses strictly outside the calculation is what makes the result usable.
- The gap this page fills: every line of the subtraction shown, annual and monthly views together, the burden as a percentage of gross, an error instead of a silent zero, and an explicit separation from take-home-pay tools and from real-estate effective gross income.
Frequently asked questions
The money you actually have to live on: gross income minus taxes minus deductions. On the pre-filled example, $100,000 gross leaves $73,000 per year, or $6,083.33 per month.
Not as tools. Take-home-pay tools compute tax from your salary and give net pay per paycheck. This tool takes your actual tax and deduction amounts and gives annual and monthly spendable income for budgeting. The figures can coincide, but the questions and the inputs differ, and this page does not duplicate take-home-pay content such as tax brackets or pay frequencies.
Subtract: gross income minus (federal tax plus state and local tax) minus (retirement plus health premiums plus other deductions). Monthly effective income is the annual figure divided by 12.
Gross income is the total before anything is taken out; effective income is what remains after taxes and deductions. The gap between them, shown here as a burden percentage, is the share of gross pay that never reaches your spending.
Add every source together into the gross income field before subtracting taxes and deductions. Freelancers enter total revenue as gross and put expected income and self-employment tax in the tax fields.
Amounts withheld before you see the money: retirement contributions, health insurance premiums, HSA or FSA contributions, union dues, and similar items. Social Security and Medicare withholding belong in the tax fields.
No. Those are paid out of your effective income after you receive it; they are budgeting items, not income deductions. Entering them would understate the spendable figure and make it incomparable with anything else.
The tool shows an error instead of a silent zero, because that combination almost always means a figure was misplaced, for example a monthly amount entered as an annual one. Fix the entry and calculate again.
No. Real-estate EGI is rental income minus vacancy and credit losses, a property metric. This page computes personal spendable income after taxes and deductions.
Yes. Enter your total freelance revenue as gross, and put the income and self-employment tax you expect to pay in the tax fields. Estimated quarterly payments count as tax paid.
