What a "Fair Rate" Actually Means When Audience Quality Varies Wildly

Two creators with the same follower count are not the same deal, and treating them as equivalent is the single most common pricing mistake in the category.

A fair rate calculation has to account for at least three variables beyond follower count:

In-market percentage — the share of a creator's audience that overlaps with your actual target demographic and geography. A creator with 72% in-market audience is delivering meaningfully more usable reach than one at 45%, at the same follower count.

Engagement rate relative to tier median — not engagement rate in isolation, since what counts as "good" varies enormously by follower count and category, but engagement relative to peers in the same band.

CPM relative to category benchmark — the actual efficiency of the spend, which can diverge from both follower count and engagement rate depending on content format and platform mix.

A fair rate weights all three against the benchmark set, which is why two creators at 180K followers in the same category can have fair rates that differ by £1,000 or more. The number isn't arbitrary — it reflects a real difference in what the brand is actually buying.

Rate cards built purely on follower tiers will systematically overpay for reach and underpay for quality, in both directions, every time.
