Influencer Campaign Cost Calculator
Calculation only: this tool estimates costs from the numbers you enter. It is not financial advice, and real results depend on audience quality and campaign terms.
How to use this tool
- Enter followers, engagement rate, post count and rate per post, then press Generate.
- Read the estimate: reach per post, total cost and cost per engagement.
- Use Load sample for 50,000 followers at 4% engagement, 3 posts at $200 each.
Worked example
For 50,000 followers at 4% engagement, estimated reach is 2,000 engagements per post. For 3 posts at $200 each, total cost is $600, so cost per engagement is $600 divided by 6,000 engagements, which is $0.10.
What this tool does not do / Limits
Reach here is a simple multiplication of followers by engagement rate; it does not account for fake followers, audience overlap, platform algorithms or content quality, and it is not financial advice.
Frequently asked questions
What does cost per engagement mean?
Total campaign cost divided by total estimated engagements across all posts. Lower means each engagement costs less, but it says nothing about sales.
Why might real results differ?
Engagement varies by post, audience and timing, and follower counts can include inactive accounts.
