Should You Manage Ads In-House or Hire an Agency?
Whenever a business allocates a marketing budget, one recurring question comes up: manage advertising in-house, or hand it off to a specialized agency? In-house management adds a fixed salary cost but no extra fee on the ad spend itself, while an agency skips the salary but charges a percentage fee on every dollar spent — a fee that adds up fast as spend grows.
The math is straightforward: total in-house cost equals ad spend plus the manager's salary, while total agency cost equals ad spend plus (ad spend × fee rate). When ad spend is small, the fixed salary tends to dominate, making the agency option cheaper. As ad spend grows, the percentage fee eventually overtakes the salary cost, and in-house management becomes the more economical choice.
Of course, this is a pure cost comparison — real decisions should also weigh in-house expertise, how quickly the team can adapt to platform changes, and the overhead of hiring and managing internal staff. If your ad spend is growing quickly, calculating the break-even point in advance helps you decide exactly when it makes sense to bring the function in-house.

Frequently Asked Questions
Most agencies charge somewhere between 10% and 20% of ad spend as a management fee, though the exact rate depends on contract size and the scope of services included.
Not necessarily. In-house management can lower costs, but an internal hire may have less specialized expertise and be slower to adapt to platform changes than a dedicated agency, so cost and performance should be weighed together.
When ad spend is low, an agency that only charges a percentage fee is often cheaper than carrying a fixed in-house salary, since you're not paying for capacity you don't need.
