A Meta ads agency costs your ad spend plus a management fee, and sometimes a separate charge for creative. Of the ten agencies we checked, six publish a starting fee, from $650 a month (the low end of LYFE Marketing’s range) to $5,000 a month (Knowlify and Flighted), and four do not publish one.
Raintree charges a flat $2,400 a month. Below, we show the arithmetic of that flat fee against a percentage of spend at four budgets, including the budgets where a percentage model is cheaper.
Disclosure and method: Raintree Ads publishes this page and is one of the agencies compared. Every fact about another agency comes from that agency’s own website as of November 11, 2026, linked in its section. We have not hired these agencies or tested their results, so this compares published scope, pricing and terms, not quality or campaign performance. Fees and terms change, so confirm them with each agency before you sign.

Each agency’s own published statements, checked November 11, 2026, ordered by published starting fee. “Not published” means we found no figure on the agency’s site.
1. Ad spend. What you pay Meta for impressions and clicks. It is billed by Meta directly to your card or invoice, not by the agency, at every agency on this page.
2. Management fee. What you pay the agency to plan, run and report on the account. This is the layer that varies most, and the next section covers how it is priced.
3. Creative. The ads themselves. Some agencies include creative in the fee and some bill it separately. Raintree includes a bi-weekly creative refresh in the $2,400 fee, and UGC creator sourcing is a $1,500 a month add-on with creator fees billed separately (see the pricing page). Knowlify says it has no per-creative charges; Flighted says UGC creator fees are billed on top of its retainer; and LYFE Marketing’s video packages say to provide video or purchase a LYFE video plan. Ask where creative sits before you compare fees, because a lower fee without creative can cost more in total.
A percentage fee is spend times the rate. At 10%, $25,000 a month of spend costs $25,000 times 0.10, or $2,500, in fees; at 15% it costs $25,000 times 0.15, or $3,750. A flat fee stays the same at every budget, so as a share of spend it is $2,400 divided by spend: $2,400 divided by $25,000 is 9.6%.
| Monthly spend | Fee at 10% | Fee at 15% | Flat fee | Flat as % of spend | Total with flat | Total with 10% to 15% |
|---|---|---|---|---|---|---|
| $10,000 | $1,000 | $1,500 | $2,400 | 24% | $12,400 | $11,000 to $11,500 |
| $25,000 | $2,500 | $3,750 | $2,400 | 9.6% | $27,400 | $27,500 to $28,750 |
| $50,000 | $5,000 | $7,500 | $2,400 | 4.8% | $52,400 | $55,000 to $57,500 |
| $100,000 | $10,000 | $15,000 | $2,400 | 2.4% | $102,400 | $110,000 to $115,000 |
Three things the table shows:
This page models percentage fees at 10% and 15% of spend to show the arithmetic. It is not a claim about what any specific agency charges; the comparison table above lists what each agency actually publishes.
One fixed monthly fee regardless of spend. Raintree charges a flat $2,400 a month. GrowthSpree publishes a flat retainer starting at $3,000 a month, and Flighted a flat monthly retainer based on your ad spend tier, from $5,000 a month, so a flat retainer can still step up as you grow.
The upside is predictability, and the fee does not reward the agency for spending more of your money. The downside shows up at low budgets: at $10,000 a month, $2,400 is 24% of spend.
Choose it when: you spend roughly $16,000 a month or more, or you want a fee that does not rise when you scale.
The fee is a share of what you spend on ads, so it rises and falls with your budget. KlientBoost says “sometimes a percentage of ad spend makes the most sense” and uses it for some clients.
The upside is a low fee at small budgets: 10% of $10,000 is $1,000. The downside is that the fee grows with spend whether or not the work does, and the agency earns more when you spend more.
Choose it when: your budget is under about $16,000 a month and you want the fee to stay small while you test.
A base fee plus a percentage, often above a spend threshold, or a fee tied to results. KlientBoost offers pay-for-performance alongside its flat and percentage options.
The total lands between the two models above. Ask for the exact formula and run it at your current spend and at twice your current spend before you sign.
Choose it when: you want some of the fee tied to growth and can get the formula in writing.
Of the ten agencies we checked on November 11, 2026, published starting fees run from $650 a month (the low end of LYFE Marketing’s range) to $5,000 a month (Knowlify and Flighted). Raintree charges a flat $2,400 a month, and four of the ten do not publish a fee. Ad spend is paid to Meta on top.
It depends on your spend. Against a flat $2,400 fee, a 15% fee is cheaper below $16,000 a month and a 10% fee is cheaper below $24,000. Above those budgets the flat fee costs less, and the gap grows: at $50,000 a month it is $2,600 to $5,100 a month.
There is no single minimum. LYFE Marketing recommends at least $500 a month, KlientBoost works with budgets from $5,000, Flighted requires $25,000, and Raintree’s best fit is $10,000 or more a month in Meta spend. Below about $10,000, the fee is a large share of the total.
At Raintree, first ads go live within 7 days of signing, and we ask clients to plan on a full quarter to judge the work, since B2B SaaS sales cycles run longer than Meta’s optimization window. In our FlexiBake case study, cost per lead fell 74% and lead volume rose 289%.
