Discretionary expenses are the costs you could reduce or cut entirely without threatening your ability to live, work, or stay out of trouble with creditors. Dining out, streaming subscriptions, vacations, hobbies, and upgrades all qualify. They sit opposite non-discretionary expenses like rent, basic utilities, groceries, insurance, and minimum debt payments, which carry real consequences if you skip them. The line matters for everyday budgeting, and it also matters in places most people don’t expect, including bankruptcy court and IRS collections.
How to Tell a Discretionary Expense From a Necessary One
The test is simple. If you stopped paying for something tomorrow, would your household still function? If yes, it’s discretionary. A gym membership, a weekend brunch habit, a new pair of running shoes when last year’s still work — all discretionary. Rent, a basic phone plan for work, and a baseline grocery budget are not.
The harder part is that most real spending doesn’t sit cleanly on one side. Food is necessary, but ordering delivery four nights a week isn’t. A phone is necessary; a $1,200 upgrade is a want. Getting to your job is necessary; a $600 car payment when public transit would work is a preference. This is where budgets quietly bleed money. People label a category “necessary” and stop examining how much of it is actually optional. The grocery bill is necessary; the $8 cold-pressed juice inside it isn’t. You rarely need to cut a whole category — you just trim the discretionary layer off the top.
Common Examples
Bureau of Labor Statistics figures from the 2024 Consumer Expenditure Survey show where the money tends to go. The average household spent $3,945 on food away from home, $3,609 on entertainment, $2,001 on clothing and related services, and $643 on alcohol in a single year.1Bureau of Labor Statistics. Consumer Expenditures – 2024 Those four categories alone add up to more than $10,000, and nearly all of it is discretionary.
Other common discretionary expenses:
- Subscriptions and memberships: streaming video, music, meal kits, news apps, gym dues, software services. These stack up quietly.
- Travel and vacations: flights, hotels, rental cars, and everything attached to a trip you don’t have to take.
- Hobbies and recreation: concert tickets, golf, photography gear, craft supplies, sporting goods.
- Upgrades: the premium phone, the nicer car trim, the larger apartment when the smaller one was fine.
- Personal services: salon visits, spa treatments, housecleaning, lawn care you could do yourself.
None of this is inherently wasteful. Discretionary spending is how you enjoy your life. The point of naming it isn’t to eliminate it. It’s to make sure you’re choosing it on purpose instead of letting it happen by default.
Budgeting Around Discretionary Spending
The best-known framework is the 50/30/20 rule: 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment. The 30% slice is your discretionary budget. Treat it as a ceiling, not a target. If you’re routinely past 30%, you’re probably crowding out savings or quietly adding debt.
A more granular method is zero-based budgeting, where every dollar of take-home pay gets a specific job before the month starts. Dining, entertainment, and clothing each get a hard cap. When the entertainment line hits zero mid-month, you stop. This works well for people who find broad percentages too abstract, because it forces line-item decisions.
Either approach starts the same way. Pull two or three months of bank and credit card statements, mark each transaction as necessary or discretionary, and total both sides. Most people are surprised. Small recurring charges — a $15 subscription here, a $7 app there — compound in ways that don’t register day to day.
Lifestyle Creep
Lifestyle creep is when spending expands with income and your savings rate stays flat despite earning more. You get a raise and start eating out more. A bonus arrives and the old couch suddenly needs replacing. None of it feels extravagant, which is what makes it effective at erasing financial progress.
The mechanism is almost always discretionary spending. Your rent doesn’t rise because you got promoted, but your restaurant budget, clothing choices, and vacation expectations do. The most reliable defense is a rule: when income goes up, raise your savings allocation first, before adjusting your lifestyle. If half of every raise goes to savings or debt payoff before you touch the discretionary budget, you still enjoy higher earnings without quietly canceling the benefit.
Where the Government Draws the Line
The discretionary-versus-necessary distinction isn’t only a budgeting idea. It carries legal weight in two places most people don’t think about until they’re already there.
The Bankruptcy Means Test
When someone files Chapter 7 bankruptcy, the court applies a means test to decide whether they qualify or whether their income is high enough to repay creditors through Chapter 13 instead.2Office of the Law Revision Counsel. 11 US Code 707 – Dismissal of a Case or Conversion The test subtracts “allowable” monthly expenses from income, and allowable is defined by the IRS National Standards and Local Standards — fixed caps on food, clothing, housing, utilities, and transportation based on family size and location.3U.S. Department of Justice. Means Testing – US Trustee Program Spending above those caps, even if you really incurred it, is treated as discretionary income available to creditors. A $300 restaurant habit doesn’t count. Neither does premium cable or a gym membership.
This matters before you file. Courts look unfavorably at filers who kept up heavy discretionary spending while falling behind on debts, so the months leading into a filing become evidence.
IRS Collection Standards
If you owe back taxes and can’t pay in full, the IRS uses its Collection Financial Standards to decide what you can afford each month.4Internal Revenue Service. Collection Financial Standards It adds up your allowable necessary expenses using the National Standards for food, clothing, and personal care, and Local Standards for housing and transportation. Anything left is money the agency expects to go toward the tax debt.
The caps are strict. In 2025, a single person gets $839 per month across food, housekeeping, clothing, personal care, and miscellaneous combined. A family of four gets $2,129.5Internal Revenue Service. 2025 Allowable Living Expenses National Standards The IRS generally allows the lesser of what you actually spend or the applicable standard. You can request a deviation if your real necessary costs exceed the caps, but the burden is on you to document it.
In both situations, the government isn’t interested in your personal view of what feels necessary. It publishes dollar figures, and your spending either fits inside them or it doesn’t.
A Note on Discretionary Expenses in a Business
For a business, discretionary spending covers things like marketing beyond what’s needed to sustain revenue, upgraded office furniture, employee perks, team retreats, and above-market professional development. These costs help operations or morale but aren’t strictly required to keep the doors open.
One point worth flagging: discretionary does not mean non-deductible. A business can deduct any expense that is “ordinary and necessary” for its trade, meaning common in the industry and helpful to the business.6Office of the Law Revision Counsel. 26 US Code 162 – Trade or Business Expenses A marketing campaign you didn’t strictly need can still be deductible.
The main exception is entertainment. Since the Tax Cuts and Jobs Act, businesses cannot deduct expenses for entertainment, amusement, or recreation, including client event tickets, golf outings, and club dues.7Internal Revenue Service. Tax Cuts and Jobs Act – Businesses Business meals stay 50% deductible if the taxpayer or an employee is present and the meal isn’t lavish.8Office of the Law Revision Counsel. 26 USC 274 – Disallowance of Certain Entertainment, Etc., Expenses So the entertainment budget is discretionary from an operations standpoint and non-deductible from a tax standpoint, which is a double reason to scrutinize it.
