CPM Calculator
Solve for the missing variable of an influencer campaign. Drop in any two of total spend, views, and CPM to compute the third.
Inputs
Fill any two fields — leave the third blank to compute it.
Computed value
The third value, derived from the two you provided.
Enter any two values to compute the third.
Formula: CPM = (spend / views) × 1000. Spend = (CPM × views) / 1000. Views = (spend / CPM) × 1000. Fill any two of the three fields; the third is solved on the fly.
CPM (cost per mille) normalizes spend against audience size — useful for comparing reach efficiency across influencers of different follower tiers. The same brand campaign can look cheap on a mega-creator and expensive on a micro-creator, even when both delivered equivalent views.
