It’s the classic dilemma for growing businesses: you know you need to ramp up marketing, but how? Do you try to do it yourself on nights and weekends? Do you bite the bullet and hire a full-time Marketing Manager? Or do you retain an agency?
Most founders make this decision based on the sticker price. They see an agency quote for $3,000/month and think, "I could hire someone for that!"
This is flawed math. To make the right decision, you need to compare the Total Cost of Ownership (TCO) of each model, not just the salary or retainer fee. Let’s break down the real numbers.
Option 1: The DIY (Do-It-Yourself) Founder
This is where everyone starts. It feels "free" because you aren't writing a check to anyone else. But as a business owner, your time is your most expensive asset.
⏳ The "Time is Money" Calculation
If your time is worth $100/hour (a conservative estimate for a founder), and you spend 10 hours a week writing blogs, posting on social media, and fiddling with ads:
10 hours/week * $100/hour * 4 weeks = $4,000/month.
That's the true cost of DIY. And that's time you aren't spending on sales, product development, or strategy.
Option 2: The In-House Hire
Hiring a full-time employee feels like the "grown-up" thing to do. You get total control and a dedicated resource. But the base salary is just the tip of the iceberg.
Let's look at the "fully loaded" cost of a mid-level Marketing Manager with a base salary of $75,000/year.
The True Cost of an Employee (Year 1)
Total First-Year Cost: ~$107,000
Furthermore, a single employee is rarely an expert in everything. A great copywriter is usually not a great technical SEO. A great social media manager is rarely a PPC expert. You hire a generalist and get average results across the board.
Option 3: The Agency Model
With an agency, you pay a flat monthly retainer. It often seems high compared to a salary, but remember what it includes.
For a retainer of, say, $4,000/month ($48,000/year), you don't get one person. You get access to a team of specialists: an SEO strategist, a content writer, a paid ads manager, and a web developer. You pay zero payroll taxes, zero benefits, and zero software costs.
The downside? You are not their only client. You have less direct control over their daily tasks, and communication happens through structured meetings rather than tapping someone on the shoulder.
The Cost & Expertise Comparison
| Feature | DIY Founder | In-House Hire | Marketing Agency |
|---|---|---|---|
| Annual Cost | $48k+ (in time) | $100k - $130k+ | $36k - $72k+ |
| Expertise | Novice | Generalist (Jack of all trades) | Specialists (Team of experts) |
| Tools & Tech Cost | ~$300/mo | ~$800/mo | Included ($0) |
| Time to Launch | Immediate | Slow (Hiring & onboarding) | Fast (Proven processes) |
| Scalability | None (Limited by your time) | Low (Must hire more staff) | High (Just increase budget) |
The Verdict: The "Hybrid" Model Wins
For most companies between $1M and $10M in revenue, the best approach is neither pure in-house nor pure agency. It’s a Hybrid Model.
Hire a junior-level in-house "Marketing Coordinator" whose job is to manage internal communications, social media posting, and coordinate with external vendors. Then, hire a specialized agency for high-skill, high-impact work like Paid Ads (PPC), Technical SEO, and high-level strategy.
This gives you the day-to-day control of an in-house employee combined with the specialized expertise and scalability of an agency—often for less than the cost of one senior full-time hire.
