EBITDA versus SDE: are you valuing an investment or buying yourself a job?

Why the owner’s role changes the question

A small business may depend on its owner to deliver work, manage staff and find customers. An owner-operator buyer may plan to perform that role personally. An investor or strategic buyer may need to pay someone else to do it. Both can be looking at the same accounts while asking different economic questions.

Seller’s discretionary earnings, often shortened to SDE, typically seeks to describe an owner-operated earnings benefit after defined adjustments. The exact treatment is not universal. Ask for the calculation rather than relying on the label. EBITDA is also only a starting measure: reported EBITDA and normalised EBITDA can differ materially.

A worked owner-salary reconciliation

The salary costs are examples, not remuneration benchmarks. If the owner performs several roles or works unusually long hours, the replacement cost may be higher. If a buyer already has the capability, any buyer-specific benefit needs separate consideration under the valuation brief.

Do not transfer a multiple between earnings measures

A multiple quoted against SDE cannot simply be applied to EBITDA as though the measures were interchangeable. Similarly, a database of EBITDA transactions is not automatically evidence for multiplying an unreconciled SDE figure. Check the metric, period, company size, transaction basis and adjustments.

Arithmetic illustration only: 3.0× the £200,000 SDE-style figure is £600,000. The same 3.0× applied to £135,000 normalised EBITDA is £405,000. The £195,000 difference is caused by the earnings definition, not evidence that either price is right. The chosen 3.0× is hypothetical and does not represent a market recommendation.

Turn earnings into a realistic buyer cash view

An owner-operator still needs to live, pay tax, replace equipment, support stock and debtors and service any acquisition finance. The ability to work in the business does not remove those cash needs. Ask how much of the apparent earnings benefit is compensation for your own labour and how much is a return on the purchase investment.

If you plan to step back after a year, model the replacement team from that point. A deal that only works while you perform every role may not deliver the investment outcome you expect. See our buyer-side business valuation guide for the wider funding questions.

Two working owners: why a single salary add-back can mislead

A seller’s earnings measure may assume that one buyer replaces one working owner. That assumption can break down where two founders both work full time, a spouse provides administration or the owner combines a technical role with management.

Separate hypothetical example: a company reports £100,000 EBITDA after paying two working owners £60,000 each. Adding back both costs gives £220,000 before replacing either role. If a buyer personally takes over one role but needs an employee costing £55,000 for the other, the simplified owner-operator benefit is £165,000. If an investor instead needs two replacement roles costing £55,000 and £70,000, the simplified normalised EBITDA is £95,000.

The arithmetic is £100,000 + £120,000 − £55,000 = £165,000 for the owner-operator scenario, and £100,000 + £120,000 − £55,000 − £70,000 = £95,000 for the investor scenario. Costs, roles and definitions are invented for this example. Neither amount is personal take-home pay, a complete cash forecast or evidence of an appropriate multiple.

Separate working income from the return on your purchase

In the £165,000 owner-operator scenario, the buyer is providing labour as well as capital. They should understand what comparable work would cost, how much time it requires and what remains after the other cash needs of the business. Otherwise, compensation for working long hours can be mistaken for a return on the purchase investment.

Ask what happens during illness, holidays or a future step back from daily operations. If a second hire becomes necessary, the investment case changes. Consider capital expenditure, working capital, tax, financing and reserves separately; an SDE-style figure is not an amount that can automatically be withdrawn each year.

This is why a buyer’s intended involvement should be part of the initial brief. A valuation discussion for a hands-on owner and one for a passive investor may need different assumptions, even though the underlying accounts are the same.

Check the advertised definition against the actual schedule

Preserve the original advertised calculation and build a separate reconciliation rather than silently relabelling it EBITDA. Clear definitions make disagreements easier to resolve before price expectations become fixed.

Questions to put to a broker or seller

• What exactly is included in the earnings figure?
• Which owner and family costs have been added back?
• Which roles must continue, and how has replacement been costed?
• Are the comparison multiples based on the same earnings definition?
• Does the stated value describe assets, the operation or shares?

Bring the calculation and your proposed role to the valuation discussion. A transparent reconciliation is more useful than debating an attractive multiple against an undefined profit number.
