Fractional Marketer vs Agency vs Full-Time Hire: The Real Cost for a 5-Person Business

If you run a 5-person business and you're finally ready to stop doing marketing at 10 p.m., you have three real options: hire someone full-time, sign with an agency, or bring in a fractional marketer. Each one has a price tag, and the sticker price is never the whole story.

I've been on every side of this. I've been the in-house marketer, I've worked inside St. Louis agencies, I've run my own agency, and now I work fractional. So here's the honest comparison of a fractional marketer vs agency vs full-time hire, including the parts that don't flatter me.

Fractional marketer vs agency vs full-time hire: the side-by-side

Start with the big picture. Then we'll go row by row.

Agency figures are from retainers I've seen, not a survey. Your quotes will vary.

What does a full-time marketing hire really cost?

According to the U.S. Bureau of Labor Statistics, the median annual pay for market research analysts and marketing specialists was $78,760 in May 2025. That's the "marketing specialist" role most small businesses picture when they say "a marketing person."

If you want someone more senior, someone who can set strategy and own results, you're shopping in a different aisle. BLS puts the median annual wage for marketing managers at $166,790. Very few 5-person businesses are writing that check.

And salary isn't the full cost. BLS data on employer compensation costs shows that for private industry workers, benefits made up about 30% of total compensation in June 2026. That covers things like health insurance, retirement, paid leave, and payroll taxes. Your number depends on what you offer, but it's never zero.

There's also the hidden cost: you become a marketing manager. Someone has to set priorities, review work, and decide whether it's working. For most owners, that someone is you, and you're already busy. I wrote more about this in do you need a full-time marketing person.

What does an agency really cost?

The retainers I usually see for small service businesses land somewhere around $3,000 to $5,000 a month, and I've seen plenty higher. That's not a survey number. That's what crosses my desk when owners show me their invoices.

The bigger question is what that money buys. In most agencies, your retainer funds an account manager, a project manager, the agency's margin, and billed meetings before it reaches the person producing your work. I broke this down in why you're paying $4,000 a month for four blog posts.

Two more things to check before you sign:

• Contract length. Six to twelve months is common. That's a long time to be locked in if the work is mediocre.
• Account ownership. Some agencies build your Google Ads account or website under their own logins. If you leave, you may lose your history or have to start over. Ask in writing.

What does a fractional marketer cost?

I'll use my own offer since it's the one I can speak to honestly. At Modern Marketing STL, it's $125 per production hour with a 15-hour monthly minimum, so $1,875 a month to start. Meetings are free. No setup fee. Month-to-month. You own every account and every file. Social content gets produced a full quarter ahead, so the rest of your hours go to ads, SEO, and the stuff that grows the business.

Other fractional marketers price differently. Some do flat monthly fees, some do day rates. What matters is the structure: you're paying for the person doing the work, not the layers around them.

When a full-time hire is the right choice

I'm not going to pretend fractional is always the answer. A full-time marketer makes sense when:

• You have 40+ hours of real work. Multiple locations, constant events, a busy content calendar, daily customer communication. If the work fills a week, hire for a week.
• You need someone on-site. Photographing jobs, filming crews, running a storefront's events. Some marketing needs a body in the building.
• You have someone to manage them. A junior hire without a manager tends to drift. If you or an operations lead can direct them, they can thrive.

When an agency is the right choice

• You need a big creative production. TV spots, a full rebrand with photo and video shoots, a large trade show build.
• You're running a lot of channels at scale. If you're spending serious money across many platforms in many markets, a team can make sense.
• You found a great specialist. Some small agencies are excellent at one thing. If they're transparent about who does the work and what you own, they can be worth it.

When a fractional marketer is the right choice

For most small service businesses, this is the sweet spot. A plumbing company, a cleaning service, a landscaper, a franchise location. You need consistent blogs, a tight Google Ads account, an active Google Business Profile, and someone to tell you what's working. That's usually 15 to 30 hours a month, not 160.

• Your marketing need is real but part-time. Too much for you, not enough for a full-time salary.
• You want senior judgment. At small-business salaries, full-time hires are often junior. Fractional gets you experience by the hour.
• You don't want to manage anyone. A fractional marketer plans, produces, and reports. You approve and run your business.
• You want to be able to walk away. Month-to-month means the work has to earn the next month.

Run the math for your business

Say you run a five-person HVAC company. This is an example, not a real client. You've got about 20 hours a month of marketing work: blogs, Google Ads, Google Business Profile posts, and a monthly check-in.

1. Step 1

   Count the hours

   List what needs to happen every month and estimate time for each. Be honest. Most owners overestimate.

2. Step 2

   Price each option

   Full-time: salary plus benefits plus tools, even though you only need part of a week. Agency: the retainer, and ask how many production hours it buys. Fractional: hours times rate.

3. Step 3

   Add your time

   Put a dollar value on your own hours spent managing, approving, and chasing. That cost is real.

4. Step 4

   Check the exit

   What happens if it doesn't work? Firing someone, waiting out a 12-month contract, or ending a month-to-month arrangement are very different experiences.

For that 20-hour HVAC example, fractional comes to $2,500 a month at my rate. A full-time specialist at the national median runs well over twice that once you include benefits, for a job that only needs half a week. That's the math that makes fractional work for small shops.

If you want to see what those hours turn into, here's what a fractional marketer actually does all month. Or book a call and we'll run your numbers together.
