What is a marketing agency worth?

Billings are not the number to start from when valuing a marketing agency, because a large share of what an agency invoices often passes straight through to media spend, contractors or production costs that never belonged to the agency in the first place. What actually gets valued is the agency’s normalized earnings — what is left after founder compensation, personal expenses and one-off costs are adjusted out — combined with a set of judgment calls about how durable that earnings figure is likely to be under a new owner. Two agencies with identical revenue can be worth very different amounts once those judgment calls are made honestly.

Start from normalized earnings, not billings or revenue

The starting point for most small agency valuations is a normalized earnings figure, commonly discussed using the seller’s discretionary earnings concept used across small business valuation, which adjusts reported profit for owner compensation, personal expenses run through the business, and costs that would not recur for a new owner. An agency’s income statement is built for tax efficiency, not to show a buyer what the business would actually generate under new ownership, so the adjusted figure — not the number on the tax return — is where a genuine valuation conversation starts.

Recurring retainer revenue is worth more than project revenue

A dollar of revenue under a signed retainer, renewing automatically unless cancelled, is not treated the same as a dollar of project revenue that has to be re-won from scratch, because the retainer dollar is a much better predictor of what the agency earns next year. Buyers and their advisors will typically ask for a breakdown of revenue by type — retainer versus project, contracted versus discretionary — and will weight the recurring share more heavily when assessing how much confidence to place in the earnings figure going forward. An agency that has spent years converting project clients into ongoing retainers is telling a very different story than one that starts each year at zero.

Client concentration is the single biggest discount lever

Where one or two clients carry most of an agency’s revenue, buyers apply a real discount to the price they are willing to pay, because losing one relationship after closing can mean losing a large share of the business overnight — a risk the buyer, not the seller, would be left holding. The size of that discount is not a fixed percentage; it depends on how buyers and their advisors read the specific relationships, including how long each has lasted, what the contract terms actually say, and how much of the relationship sits with the agency as an institution versus with one specific person. A broad client roster with no single account dominating revenue, backed by written contracts with real notice periods, generally supports a stronger valuation than a concentrated book, all else equal.

How buyers test retention, contract terms and notice periods

Beyond the concentration number itself, buyers will look account by account at how long each relationship has actually lasted, whether it sits on a written agreement or only an informal understanding, and how much notice either party needs to give before walking away. A short or non-existent notice period on a large account is treated as a live risk, not a technicality, because it means a client could leave with very little warning after the deal closes. Sellers who can produce this detail account by account, rather than a single aggregated revenue figure, generally get a more favourable read from a buyer’s advisors than sellers who cannot.

Owner and founder dependence discounts the number further

The more an agency’s client relationships and new business depend on the founder personally rather than on account leads, creative staff and documented processes, the more a buyer will discount the price — and the harder the agency can be to sell at all, because the buyer is really being asked to pay for a relationship they cannot inherit. Agencies that have already shifted day-to-day client contact to a broader team, and where the founder’s departure would not visibly change how clients experience the agency, tend to hold their value through a transition far better than founder-centric shops.

Why the multiples you hear about are not a rule

It is common to hear that agencies in a given niche sell for some multiple of earnings, and multiples are a normal shorthand advisors use to discuss value in general terms — but any specific figure circulating informally reflects deals with their own particular facts and is not a rule that applies to a specific agency. Two agencies with the same reported earnings can be worth very different amounts once client concentration, revenue mix and founder dependence are actually priced in, which is exactly why a rule-of-thumb multiple is a starting conversation, not an answer.

Getting an independent valuation

Because agency value depends so heavily on judgment calls about concentration, revenue mix and founder dependence rather than a formula, an independent valuation from someone who understands both business valuation and agency economics is worth commissioning before a listing goes out or an offer is accepted. It gives a seller a defensible number to negotiate from and gives a buyer a way to test whether an asking price actually reflects the agency’s earnings and risk profile.
