The Exclusivity Premium: What It Should Actually Cost You

Exclusivity clauses — restricting a creator from working with competing brands for a set period — are one of the most inconsistently priced terms in influencer contracts, largely because there's no shared reference point for what the restriction is actually worth.

A few benchmarks worth knowing:

Category-exclusive clauses (competing brands in the same category only) typically carry a 20–30% premium over the base creative fee across the placements in Harpper's index, scaling with the length of the exclusivity window.

Full exclusivity (no other brand partnerships at all during the window) commands a significantly higher premium, often 50%+, and is rarely worth it outside of ambassador-level, retainer-based relationships.

Exclusivity windows longer than 90 days show diminishing returns for the brand relative to cost — the marginal protective value of month four onward rarely justifies the marginal premium, unless the campaign specifically depends on sustained, uninterrupted association.

Exclusivity without a corresponding retainer is one of the more common overpays in the dataset: brands asking for the restriction of an ongoing relationship while structuring the deal as a one-off, which creators reasonably price at a premium.

The practical rule: price exclusivity as its own line item, tied explicitly to category and window length, rather than folding it into a general "premium" on the base rate with no clear justification either side can point back to.

Harpper's contract review flags exclusivity terms and benchmarks the premium against comparable deals before you sign.
