A few times a month, a client or a prospect asks me some version of the same thing: "Should I just hire someone in-house to run this?"
It's a fair question. I'm not going to pretend it isn't. So let's do the actual math first — the honest version, not the version that only counts salary — and then I'll tell you the part the math doesn't show you, which is the part that actually matters.
(Quick note: every number below is illustrative. Yours will be different depending on your market and the level you're hiring at. I'm showing you the shape of it, not quoting you a price.)
The math nobody runs before they hire
Say you go hire a solid mid-level paid media manager. Let's call the base salary $90,000. Reasonable for someone who actually knows what they're doing.
That $90K is not what they cost. Here's what gets added on top:
- Employer payroll taxes — Social Security, Medicare, unemployment. Call it roughly 8%. That's about $7,000.
- Benefits — health insurance is the big one, plus any retirement match. For one employee that lands somewhere around $12,000 a year, and that's on the lean side.
- Their tool stack — analytics, reporting, call tracking, competitive research, the platforms they need seats in. Easily $5,000–$8,000 a year for one person.
- Recruiting — whether it's a recruiter fee (15–25% of salary is normal) or your own time screening 40 résumés, that cost is real even if you don't write it on a check.
- Equipment, onboarding, and your time managing them. Not a clean line item, but it's not zero.
Add it up and your $90,000 hire is really a $115,000–$120,000+ commitment. That's roughly $10,000 a month — for one person.
And here's the quiet part: that one person knows your one account. That's it. That's the whole portfolio they're working from.
Now the part the spreadsheet doesn't show
This is the real argument, and it's not about money.
A lot of in-house hires come out of one company. Maybe two. They might know those businesses incredibly well — genuinely deep. But "deep on two businesses" and "deep on the craft" aren't the same thing. If they've run the same playbook in the same account for four years, they know that account. They may not have seen what breaks at 50 other ones.
Someone who's spent their career on the agency side has run this a thousand times. Different industries, different budgets, different platforms, different ways it all goes sideways. That pattern library is the asset. It's the difference between someone who's seen your exact problem before and someone who's about to see it for the first time, on your dime.
I'm not knocking in-house people. Some of the best marketers I know sit in-house. The point isn't the person. It's the structure — you're betting your entire paid channel on one human being both an expert and the right fit and sticking around. That's a lot of weight on one chair.
The failure mode nobody plans for
Here's the one that really gets people.
You hire someone. They're qualified on paper. And three months in, it's just… not clicking. Maybe the communication style grates. Maybe they're slower than you need. Maybe you just don't jive. It happens, and it's nobody's fault.
Look at your options now. You can manage around it (exhausting). You can coach it and hope (slow). Or you let them go — and that means severance, the morale hit, the channel going dark while you re-hire, then another two or three months of ramp on the next person before anything's good again. That's most of a year, gone, on a coin flip.
A real freelance team doesn't have that failure mode. If the style fit isn't right with whoever's on your account, the work just transitions to someone else on the bench who is a fit. Same expertise. No firing. No gap. No dark channel. You probably don't even feel the seam.
Now, I try hard to make sure it never gets there. A big part of my job is matchmaking — reading the client, reading the strategist, and pairing people who'll actually click from day one. I'm good at it, and most of the time the first pairing is the right one. But I'd be lying if I said the safety net wasn't a nice thing to have. With a single hire, you are the safety net, and the net is "start over."
So, should you hire in-house?
Sometimes, honestly, yes. If paid media is the entire business and you've got the volume to keep a great person challenged and growing, an in-house hire can be the right call.
But if what you actually want is expert-level work on your accounts without a $120K-a-year, single-point-of-failure bet attached to it — that's the whole reason a freelance bench exists. You get the senior person who's done this a thousand times, none of the overhead, and a structure that bends instead of breaking when something's off.
Run your own numbers. Then run them again with the risk included. That second number is the one that should make the decision.
