What is a fair break-even point for hiring a paid social agency?
An agency pays for itself when the incremental margin it adds, through better creative, faster testing, and reallocated spend, exceeds its fee plus your time. As a rule of thumb, fees under about 10 to 15 percent of managed media are easy to clear if the agency lifts contribution margin even modestly; the real cost is mismanaged spend, not the fee.
The right break-even frame: margin, not ROAS
Last-click ROAS is a poor break-even metric because it measures attribution, not margin. The clean test is whether contribution margin on agency-managed spend, after deducting the fee, exceeds what you were generating before at the same budget. If yes, the fee is covered by definition.
The hidden cost that dwarfs the fee
Mismanaged media spend is usually the larger number: budget allocated to campaigns with poor creative quality, wasted impression frequency, or audiences that do not convert. A fee of $8,000 per month is trivial if the agency corrects $30,000 in misallocated spend. The fee sensitivity conversation is usually a distraction from the spend quality question.
Time cost is real and often ignored
Include your own time in the break-even. A founder or CMO spending 10 hours per week managing an in-house junior and a platform interface has an opportunity cost. When an agency absorbs that management burden and improves output simultaneously, the real break-even is lower than the fee-only comparison suggests.

What fee-to-spend ratio is a warning sign?
Above 20 percent of managed media, the fee starts to distort incentives toward keeping spend high rather than efficient. Below 8 percent, the agency likely cannot staff the account adequately at the implied hourly math.
How do I measure whether the agency actually moved the margin?
Hold a period comparison with equivalent external conditions (same seasonality, similar spend level) and measure contribution margin per dollar spent, not platform-reported ROAS. Lautzu reconciles platform data against warehouse data rather than relying on last-click reporting.
