Disposable income, in legal usage, is income remaining after the exclusions, deductions, or expenses permitted by the law governing a particular calculation. The controlling definition matters: Chapter 13 bankruptcy disposable income and federal garnishment disposable earnings use different starting points and subtractions.

Do not treat “money left after bills” as a legal formula. A paycheck deduction or household expense can count in one calculation and not another. Start with the statute, form, or order that asks for the figure.

The Bureau of Economic Analysis defines disposable personal income as personal income minus personal current taxes. That economic measure does not subtract every living expense or determine a court-ordered payment.

Disposable income in Chapter 13 bankruptcy

Bankruptcy uses technical definitions. For the Chapter 13 confirmation provisions, 11 U.S.C. § 1325(b) starts with current monthly income, excludes specified payments, and subtracts permitted amounts reasonably necessary for support or maintenance, qualifying charitable contributions, and applicable necessary business expenditures.

The exclusions include certain child-support, foster-care, and dependent-child disability payments to the extent reasonably necessary for that child. The expense rules do not simply accept every item in a household budget. For debtors above the applicable income threshold, § 1325(b)(3) directs calculation of specified expenses under additional means-test provisions.

“Current monthly income” is itself defined by 11 U.S.C. § 101(10A). It generally uses income from a specified six-month period, with stated inclusions and exclusions, rather than just the latest paycheck. Social Security benefits are among the statutory exclusions; not every benefit or payment receives the same treatment.

If the trustee or holder of an allowed unsecured claim objects, § 1325(b)(1) requires either the specified full-value treatment of the claim or commitment of all projected disposable income during the applicable period to unsecured creditors. This is one part of confirming a Debtor's Plan, not a promise that a simple subtraction determines the entire monthly plan payment.

Bankruptcy calculation example

Assume the correct statutory income starting point is $5,000 per month. After separately identifying any required exclusions, assume the applicable rules permit $4,200 in total subtractions. The simplified disposable-income difference is $800.

Those figures are hypothetical, not approved expense allowances. They do not determine projected disposable income, resolve an objection, or establish a particular debtor’s payment. The actual forms, household circumstances, applicable figures, and other confirmation requirements still matter.

Disposable earnings in wage garnishment

For federal garnishment protections, 15 U.S.C. § 1672 defines disposable earnings as earnings remaining after amounts required by law are withheld. Earnings include wages and other covered compensation for personal services, including specified periodic pension or retirement payments.

The Department of Labor’s garnishment fact sheet distinguishes required deductions, such as relevant taxes and legally required retirement-system withholding, from voluntary deductions. Optional insurance, union dues, or voluntary retirement contributions usually do not reduce this federal base simply because payroll deducts them.

For ordinary garnishments, 15 U.S.C. § 1673 generally limits weekly withholding to the lesser of 25% of disposable earnings or the amount exceeding 30 times the applicable federal minimum hourly wage. Other pay periods require the appropriate equivalent calculation.

Support orders, specified bankruptcy orders, and federal or state tax debts have different rules or exceptions. State law can provide greater protection in an ordinary garnishment. Multiple orders and their priorities also require separate review; the percentage is not an automatic amount payable to each creditor. See Wage Garnishment for the broader process.

Paycheck calculation example

Assume weekly gross earnings are $1,000, legally required withholding is $220, and an optional payroll deduction is $80. Under the federal definition, disposable earnings are $780, not the $700 deposited after both deductions.

For an ordinary garnishment using a $7.25 federal minimum wage, compare 25% of $780 ($195) with $780 minus 30 × $7.25 ($562.50). The lesser federal ceiling is $195. The Department of Labor lists that minimum wage in its current fact sheet; the rate in effect when earnings are payable must be checked.

This illustration assumes the stated pay period and ordinary-debt category. More protective applicable state law or an existing order may reduce available withholding; support and tax collection cannot be decided from this example.

Disposable income versus take-home pay

Take-home pay usually means the paycheck amount remaining after actual payroll deductions. It can include voluntary deductions that federal garnishment law does not subtract. In the example above, take-home pay is $700 while disposable earnings are $780. Neither figure automatically supplies Chapter 13 current monthly income.

To keep inclusions and exclusions straight:

Disposable versus discretionary income

In everyday language, discretionary income usually describes what remains after necessities. It is not a substitute for either statutory calculation above. If a government or repayment program uses “discretionary income,” check that program’s current definition rather than transfer a bankruptcy or garnishment formula to it.

Five questions and documents to check

  1. Which proceeding? Identify the bankruptcy notice, garnishment order, program notice, or other document requesting the figure.
  2. Which exact term? Distinguish disposable income, projected disposable income, disposable earnings, and discretionary income.
  3. Which income period? Compare the required months or pay period with pay statements and income records.
  4. Which subtractions? Separate legally required deductions, statutory exclusions, allowed expenses, and voluntary choices.
  5. Which qualifications? Check the debt type, household facts, current forms and figures, state protections, and existing orders.

Common misconceptions

Frequently asked questions

Is disposable income calculated before or after taxes?

The context controls. Economic disposable personal income is an after-tax measure. Federal garnishment subtracts legally required withholding. Chapter 13 starts with statutory current monthly income and applies bankruptcy-specific rules.

Do living expenses reduce disposable income?

Permitted expenses can reduce Chapter 13 disposable income. They do not automatically reduce federal garnishment disposable earnings, which focuses on required withholding.

Are all paycheck deductions excluded before garnishment?

No. An employee’s authorization does not itself make a deduction legally required. Check the deduction’s legal basis and the applicable garnishment framework.

Can two legal calculations produce different amounts?

Yes. Different statutes, income periods, permitted subtractions, debt categories, and state protections can produce different figures. Identify the governing calculation before comparing the results.
