How this tool works

Brands often think in cost-per-thousand-impressions (CPM). This calculator converts your follower count and engagement rate into an estimated impressions figure, then applies a CPM to give you a comparable media value for a sponsored post.

  1. Enter total followers.
  2. Enter your average engagement rate.
  3. Set a target CPM (cost per 1,000 impressions) — 8 to 15 is a common range.
  4. Read the estimated sponsored post value.

Tips to get better results

  • Use a CPM in line with your industry — beauty and fashion often command higher CPMs than general lifestyle content.
  • This figure estimates media value only; add a separate line for production time, usage rights and exclusivity.
  • Track actual impressions after a sponsored post runs and compare them against this estimate to refine your CPM assumption over time.

Frequently asked questions

What is CPM in influencer marketing?

CPM stands for cost per 1,000 impressions — a standard advertising metric used to compare the media value of different placements, including sponsored posts.

Is estimated impressions the same as followers?

No — this calculator estimates likely reach using both your follower count and engagement rate, since not every follower sees every post.

Does this calculator set my final sponsored post price?

It gives a media-value estimate as a starting reference point; final pricing should also reflect production effort, usage rights and exclusivity.
