How much revenue do I need to hire a marketing agency?
Usually $250K+ MRR before agency math works. Below that, the agency fee is too big a % of marketing budget — you're paying for slop because the volume doesn't justify their best people.
The agency math problem
Most DTC marketing agencies charge $3-$10K/mo retainer. For an agency to deploy their A-team on your account, you typically need to be at the $7-15K/mo tier — and that's $84-180K/yr in fees.
For agency fees to be under 5% of revenue (a sustainable level), you need $1.4-3.6M/yr ($120-300K/mo). Below that, you're either getting B-team work or paying too much relative to revenue.
What works under $250K MRR
Hybrid: freelance specialists ($1-3K/mo for a specific skill — paid media buyer, email strategist, creative director) + AI tools for volume + your own time for strategy. Cheaper, faster, and you keep ownership of the playbook.
When agencies do pay back
Above $250K MRR with a clear bottleneck (you can't hire a paid media buyer fast enough, you need an integrated email + SMS + ad team, you're scaling internationally and need market-specific expertise) — agencies earn their fee. Match the agency type to the bottleneck.
