IN-HOUSE VS AGENCY

In-house marketing or an agency: what each costs, and who owns the number

An in-house manager costs about $216,800 a year with benefits. Most SEO agencies charge under $1,000 a month for one channel. Neither one owns your revenue unless someone senior makes them.

The short answer

The cheapest option owns the least

A marketing manager at the US median earns $166,790. With benefits at 30% of pay, that is about $216,800 a year for one person, before a recruiter's fee. An agency costs far less, because it does far less: one channel, judged by its own report.

The real question is who owns the revenue number. If nobody senior does, the in-house hire becomes busy and the agency becomes a vendor. A fractional CMO is the third option: one owner above both.

QuestionIn-houseAgencyFractional CMO
Yearly costAbout $216,800 for one marketing manager at median pay plus benefits. About $102,400 for a specialist. Recruiting comes on top.Usually under $12,000 for one channel. 64% of SEO agencies charge under $1,000 a month.$36,000 to $300,000, by scope. The top of the range includes the team that does the work.
Who owns the revenue numberOnly a senior hire. A manager usually owns activity: posts, campaigns, events.Nobody. The agency is paid to run its channel well.The fractional CMO, if the mandate says so in writing.
Time to startAbout three months to hire and three more to ramp.A few weeks.A few weeks.
Where it breaksOne person is asked to be strategist, writer, analyst and CRM admin.Leads go up, sales stays flat, and nobody connects the two.Nobody inside has time to act on the decisions.
Best whenThe work is steady, in one or two channels, with a leader above it.One channel needs specialist skill you will not hire for.Growth crosses teams, vendors and the CRM, and nobody owns the whole path.

The full arithmetic for a senior hire, with your own salary and fees, is on what a fractional CMO costs.

How to choose

Which one fits your business this year

Hire in-house whenyou already have a marketing leader and need more hands on steady work. The leader sets the number. The hire does the work.
Hire an agency whenone channel needs a specialist, such as paid search or SEO, and someone inside will judge it by signed revenue, not by its own report.
Hire a fractional CMO whenmarketing reports more leads, sales reports a weak quarter, and nobody can show where the money went between the two.

Check one thing this week. Pick ten jobs you sold last month and ask who can name the source of each. If nobody can, the gap is ownership, not headcount. Six questions find where the leads leak.

The third option

One owner for the number. A team that does the work.

Timur owns the mandate himself and answers for signed revenue, not activity. The team builds the system: CRM, follow-up, measurement and the channels that earn it.
