Disposable personal income is the money you keep after paying taxes. The Bureau of Economic Analysis defines it with one formula: personal income minus personal current taxes.1Bureau of Economic Analysis. Disposable Personal Income For context on where you fall, per capita disposable personal income in the United States sits at roughly $68,600 per year as of early 2026.2Federal Reserve Economic Data. Disposable Personal Income: Per Capita That is the true spending and saving power of the average American, not the larger gross number taxes still have a claim on.
The Top Line: What Counts as Personal Income
Personal income is every dollar you receive from all sources during a given period. The BEA defines it to include wages and salaries, Social Security and other government benefits, dividends and interest, business ownership, and other sources.3Bureau of Economic Analysis. Personal Income For a household, that usually means adding up four categories:
- Earned income: wages, salaries, bonuses, commissions, and tips, which appear on a W-2 or a 1099-NEC if you work as an independent contractor.
- Investment income: dividends from stocks, interest from savings accounts or bonds, and net rental income from property you own.
- Government transfers: Social Security retirement or disability payments, unemployment benefits, veterans’ benefits, and similar cash programs.
- Business income: profits from a sole proprietorship, partnership distributions, or S-corporation income that flows through to your personal return.
It does not matter whether the money came from a paycheck, a dividend, or a monthly deposit from the Social Security Administration. All of it feeds into the gross number you then subtract taxes from.
Which Taxes You Subtract
The only subtractions are personal current taxes. That category is narrower than most people assume: it covers income taxes and certain property taxes, not every bill the government sends you. The pieces that matter for most households are federal income tax, FICA, and state and local income tax.
Federal Income Tax
Federal income tax uses a progressive bracket structure, so higher portions of your income are taxed at higher rates. For 2026, brackets range from 10% on a single filer’s first $12,400 of taxable income up to 37% on income above $640,600.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Your effective rate lands below your top bracket because each slice is taxed independently. Someone earning $80,000 does not pay 22% on the whole amount; they pay 10% on the first slice, 12% on the next, and 22% only on the portion above $50,400.
FICA (Social Security and Medicare)
Social Security takes 6.2% of your earnings up to $184,500 in 2026, and Medicare takes 1.45% with no cap.5Internal Revenue Service. Topic No. 751, Social Security and Medicare Withholding Rates Your employer pays a matching amount, but only your share reduces your disposable income. High earners also face an Additional Medicare Tax of 0.9% on wages above $200,000 for most filers, or $250,000 for married couples filing jointly, with no employer match.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax
State and Local Income Taxes
Most states tax income on top of the federal obligation. Eight states charge no individual income tax at all, while top marginal rates in states that do tax income range from 2.5% to over 13%. Many cities and counties layer on local income or payroll taxes. This is why two people with identical salaries can end up with noticeably different disposable incomes depending on where they live.
What Does Not Reduce Your Disposable Income
This is where most of the confusion lives. Voluntary payroll deductions do not reduce your disposable income, even though they shrink your take-home pay. Contributions to a 401(k), health insurance premiums your employer withholds, union dues, flexible spending accounts, and charitable payroll giving are choices, not taxes.
The distinction is practical. If you earn $75,000 and pay $15,000 in taxes, your disposable income is $60,000 whether or not you also direct $6,000 into a retirement plan and $3,000 toward health coverage. Those voluntary deductions reduce what hits your bank account, but the money is still part of your disposable income because you could redirect it.
Your mortgage, car payment, groceries, and utilities don’t factor in either. Those are spending decisions you make with your disposable income, not deductions from it. The line between disposable and spent is the line between what the government takes and what you choose to do with the rest.
A Worked Example
The formula is simple: total personal income minus total taxes equals disposable personal income.1Bureau of Economic Analysis. Disposable Personal Income For a single filer earning $85,000 in wages with $1,200 in savings account interest:
- Total personal income: $86,200
- Federal income tax (estimated effective rate around 15%): $12,930
- Social Security tax (6.2% of $86,200): $5,344
- Medicare tax (1.45% of $86,200): $1,250
- State income tax (varies; assume 5%): $4,310
- Total taxes: $23,834
- Disposable personal income: $62,366
That $62,366 is the pool available for every spending and saving decision this person makes in the year. Rent, groceries, insurance premiums, retirement contributions, entertainment, and anything parked in a savings account all come out of it. The calculation does not judge how the money is used; it marks the boundary between what the government claims and what you control.
Disposable Income vs. Discretionary Income
People routinely mix up these two terms. Disposable income is your income after taxes. Discretionary income goes one step further: it is what remains after you also cover essential living expenses like housing, food, transportation, insurance, and minimum debt payments.
Disposable income tells you how much the government lets you keep. Discretionary income tells you how much genuine flexibility you have. Someone with $60,000 in disposable income but $52,000 in fixed obligations has only $8,000 in discretionary income. That $8,000 is what is actually available for vacations, dining out, extra debt payoff, or boosting savings.
The distinction shows up in practical places. Lenders look at discretionary income when deciding how much additional debt you can carry. Budgeting frameworks like the 50/30/20 rule split disposable income into needs, wants, and savings, which only makes sense once you accept that disposable income alone doesn’t tell you whether you can afford something new.
A Separate Legal Meaning: Wage Garnishment
Federal law uses a narrower version of “disposable” when courts order wages garnished, and it is worth knowing because the two definitions get confused. Under the Consumer Credit Protection Act, “disposable earnings” means the part of your paycheck remaining after amounts required by law are withheld.7Office of the Law Revision Counsel. 15 USC 1672 – Definitions Required withholdings include federal, state, and local taxes plus your share of Social Security and Medicare.8U.S. Department of Labor. Fact Sheet #30: Wage Garnishment Protections of the Consumer Credit Protection Act Voluntary deductions like health insurance or 401(k) contributions are not subtracted, so your disposable earnings for garnishment purposes are usually higher than the net pay you see deposited.
Once disposable earnings are calculated, garnishment for ordinary consumer debts cannot exceed the lesser of 25% of those earnings or the amount by which weekly earnings exceed 30 times the federal minimum wage.9Office of the Law Revision Counsel. 15 USC 1673 – Restriction on Garnishment Child support and alimony orders allow higher percentages, up to 50% if you are supporting another family or 60% if you are not.8U.S. Department of Labor. Fact Sheet #30: Wage Garnishment Protections of the Consumer Credit Protection Act Federal student loan and other government debt garnishments are capped at 15%. If a garnishment is in play, remember that courts use this paycheck-specific definition, not the broader economic one.
