Discretionary Expense
A discretionary expense is a recurring cost the current owner chose to run through the business but that a new owner would not have to incur to produce the same revenue, such as a personal vehicle, family travel, club memberships, or a relative on payroll who does not work. Discretionary expenses are added back when recasting earnings, and each one holds only as far as the document behind it goes.

The test that decides whether it survives
Three questions settle most discretionary add-back arguments.
First: would the business generate the same revenue next year if this spending stopped? Where revenue depends on it, the cost is operating, not discretionary. Client entertainment that demonstrably drives referrals is the hardest case, and buyers routinely haircut it.
Second: can the amount be tied to a specific ledger entry, invoice, or tax return line? An add-back sourced from a general ledger export survives. An add-back sourced from the owner's recollection does not.
Third: does the benefit accrue to the owner personally? Personal benefit is what makes a cost discretionary. An owner's taste for an expensive but genuinely business-purposed line item, an over-specified truck fleet for instance, is a capital allocation question rather than an add-back.
Sizing has a trap of its own. Meals are generally 50% deductible and entertainment has been non-deductible since the 2017 Tax Cuts and Jobs Act, with narrow exceptions and a temporary 100% deduction for restaurant meals in 2021 and 2022, so a P&L rebuilt from a tax return can show well under half the cash actually spent in those categories. Those lines size correctly off the general ledger, not off the return. One boundary is worth stating before the schedule is built. Owner-only perquisites — the vehicle, the phone, the club dues, the owner's life insurance — also appear inside the fully loaded owner-compensation figure. They belong on one schedule or the other, never both, and the same dollars counted twice is the error a buyer's accountant finds first. See owner-compensation.
Documentation is the other half of the test. Every item below is defensible when the supporting record exists and indefensible when it does not.
- Personal vehicle: lease or loan statements, insurance declarations, and the split between business and personal mileage
- Family cell phones and personal subscriptions: the carrier invoice showing which lines belong to non-employees
- Country club, gym, and social memberships: the annual dues invoice in the company's name
- Personal travel: the expense report or card detail, separated from genuine trade-show and customer travel
- Charitable and political donations: the acknowledgment letters, which are also the cleanest audit trail on the P&L
- Family members on payroll with no operating role: the payroll register, plus a specific answer about what they actually do
- Owner's life and disability insurance where the owner or the owner's family is the beneficiary: the policy declaration page
Worked example: what a discretionary schedule is worth
A $1.4 million revenue services business presents this discretionary schedule for the trailing year.
Owner's vehicle lease, insurance, and fuel: $14,400. Personal and family travel: $8,500. Country club dues: $6,900. Family cell phone lines and streaming subscriptions: $3,600. Owner's whole life insurance premium: $5,400. Total: $38,800.
At an illustrative 3.0x SDE multiple, that schedule carries $116,400 of asking price.
In diligence the buyer's accountant accepts the vehicle, the dues, the phones, and the insurance, but rejects the $8,500 of travel: the card detail ties four of those trips to trade shows the business attends every year, making them ordinary operating travel that was miscoded as personal. The schedule falls to $30,300 and the supportable price falls by $25,500.
The second-order cost is larger than the first. A buyer who catches one unsupported add-back discounts the credibility of the entire schedule, including the owner compensation line that was correct all along.
Not the same thing as a one-time expense, or a related-party one
These three categories get merged on most add-back schedules, and they fail in diligence for different reasons.
A discretionary expense is recurring but optional. It appeared last year, it will appear next year if the seller stays, and it disappears only because the owner changes. A one-time expense is the reverse: mandatory but non-recurring. The business had no choice about the legal settlement or the flood, and the event is not expected again. Keeping them in separate sections lets a buyer test each with the right question, because asking whether a legal settlement was discretionary produces a confused answer while asking whether it recurs produces a clean one.
A related-party transaction is a third category, and often the opposite of an add-back. Below-market rent paid to an owner-controlled entity means normalized expenses go up, not down, because the buyer will pay market for space the business genuinely needs.

CastBack scans operating-expense labels for discretionary language such as owner, personal, auto, and travel, and surfaces each hit as a suggestion for the broker to confirm; a keyword match never produces an automatic add-back. See how a recast is produced.
