How much is a marketing agency worth?

Short answer: it depends entirely on how the revenue is shaped. An agency on retainers, with no client over 15%, is a real business a buyer can underwrite. An agency living project-to-project on two whales is a job with staff — and gets priced like one. There is no verified realized multiple for agencies specifically in the data we use, so this page works from category data and labels it. See Marketing Agencies, then run your mix through the valuation calculator.

The number

BizBuySell's realized-sales table (trailing five years through Q2 2026) breaks out graphic and web design businesses but not marketing agencies as such — adjacent data, not your comps, so we won't pass it off as an agency multiple. The honest starting frame is the The IBBA Market Pulse (Q2 2026) size ladder runs across all small businesses: 2.0× SDE under $500K, 2.8× at $500K–$1M, 3.1× at $1M–$2M, then EBITDA multiples — 4.8× at $2–5M and 5.8× at $5–50M. For scale context only: public companies in Damodaran Online's Advertising bucket (January 2026) trade at 12.00× EV/EBITDA. That is a proxy ceiling for large, liquid companies — not your price. A small private business sells at a steep discount for size, illiquidity, and owner risk.

Worked example, math shown:

• Net revenue (assumption — fees, excluding pass-through ad spend): $900,000
• SDE margin (assumption): 20% → SDE = $900,000 × 0.20 = $180,000
• Price bracket is under $500K, so the ladder gives 2.0×: $180,000 × 2.0 = $360,000

Now the agency-specific truth: two firms with identical $180,000 SDE can be $200,000 apart. The one with 70% retainer revenue, a second-in-command, and twelve clients gets the top of the range — and sometimes an EBITDA conversation with a strategic buyer. The one with two clients at 60% of revenue gets an earnout-heavy offer, because the buyer is being asked to insure the seller's client risk. Structure is the multiple.

How buyers actually value a marketing agency

Buyers rebuild the P&L before they price anything. First: net revenue. If you bill clients for ad spend and pass it to platforms, that gross billings number is not revenue — sophisticated buyers strip pass-through on sight, and agencies quoting multiples off gross billings lose credibility in the first meeting. Second: retainer vs. project mix. A $15,000/month retainer with a 12-month term and 90-day notice is near-contracted revenue. Project work is a pipeline that empties every quarter. Buyers weight them completely differently even when the dollars match. Third: client concentration — the classic screen is no client above 15–20% and the top five under half. Break it and expect the price to convert into an earnout tied to those clients renewing. Fourth: who owns the relationships. If clients call the founder's cell and the founder personally approves every deliverable, the buyer is purchasing key-person risk. And fifth, increasingly: what AI does to your cost structure. Buyers in 2026 ask how much production is systematized — an agency whose margins depend on billable junior hours is being repriced by the market as they read your deck.

What raises the price — and what kills it

Raises it:

• Retainers at 60%+ of net revenue with terms, notice periods, and documented renewal history
• A niche with pricing power — agencies that serve one industry deeply outsell generalists
• An account team clients know by name, so relationships survive the founder's exit
• Productized services with published scope and margin — offers that sell without a custom proposal every time

Kills it:

• One client at 35% paying late and renegotiating quarterly
• Revenue booked off gross billings in the teaser — diligence restates it and trust dies with the multiple
• Founder-led sales with no pipeline the team generates
• White-label dependence: your biggest 'client' is another agency that can in-source tomorrow

Move your number

Three levers:

• Convert projects into retainers. Every project client who signs a monthly optimization, content, or paid-media retainer moves revenue into the bucket buyers pay full price for. The ClaroPro team builds the client-ops layer — onboarding, reporting cadence, invoice follow-up — that makes retainers renew without the founder hand-holding each account.
• Fix how clients pay you. Retainers dunned on stored cards instead of invoiced-and-chased, and ad-spend pass-through separated cleanly from fees, protects margin and cleans the P&L a buyer sees. That's the Finix payments team's lane.
• Systematize delivery. Documented playbooks, templated reporting, and AI-assisted production pipelines that hold margin as you scale — a Nova engineering team can build the internal tooling so delivery quality stops depending on who stayed late.

Run your net revenue and margin in the calculator, prefilled for marketing agencies — using net revenue, not gross billings.

This is an educational framework with shown math, not an appraisal. A real price is set by a real buyer on a specific day, and for agencies a large share of it often arrives as an earnout after clients renew. These caveats exist to protect the owner: they keep you from overpaying for revenue that's really pass-through, underselling a retainer base that's genuinely durable, or signing an earnout whose targets you don't control. Never invent. Show the math. We're on the side of the business owner.
