Facebook ads agency pricing typically falls into one of three models, and most agencies use some combination of the three.

1. Flat monthly retainer

Ranges roughly $1,500–$5,000/month for small-to-mid businesses, scaling higher for larger accounts.
This usually covers strategy, campaign management, and reporting — but rarely includes ad spend itself.

2. Percentage of ad spend

Common structure: 10–20% of your monthly ad budget, often with a minimum monthly fee regardless of spend.
Spend $10,000/month and a 15% fee adds $1,500 on top — meaning the agency earns more as your spend grows, whether or not performance improves proportionally.

3. Hybrid

A smaller flat fee plus a percentage — designed to guarantee the agency a baseline income even on lower-spend accounts.

What's usually NOT included

  • Ad creative production (often billed separately)
  • Landing page design or copywriting
  • Weeks of onboarding time before your first campaign launches
  • Direct account access — many agencies keep you as a viewer, not an owner

The real cost most people miss

Beyond the invoice, the bigger cost is often time-to-first-result.
Agency onboarding commonly takes 2–4 weeks before a first campaign even launches, and contracts frequently run 3–6 months minimum — meaning a slow start locks you in regardless.
