You will get actionable tips to improve your rate, whether you are a nano-creator just starting out or an established influencer managing brand deals.

Pricing your services is one of the hardest parts of being a creator. The Influencer Rate Calculator uses your follower count and engagement rate to suggest fair rates for posts, stories, reels, and videos across platforms. The YouTube Revenue Calculator helps you estimate ad income based on views, CPM, and RPM so you can forecast earnings and plan your upload schedule accordingly.
Frequently Asked Questions
How is Instagram engagement rate calculated?
Instagram engagement rate is typically calculated by dividing total interactions (likes + comments) by your follower count, then multiplying by 100. Some methods also include saves and shares. Our calculator supports multiple formulas and shows how your rate compares against benchmarks for your follower tier.
What is a good engagement rate on TikTok?
Average TikTok engagement rates tend to be higher than other platforms, with most creators seeing between 3% and 9%. Rates above 10% are considered excellent. Our TikTok Engagement Calculator lets you calculate by followers or by views and see exactly where you stand.
How much should I charge for a sponsored post?
Rates vary widely based on platform, niche, follower count, and engagement rate. A common starting point is $10 per 1,000 followers, but creators with high engagement can charge significantly more. Our Influencer Rate Calculator factors in your specific metrics to provide personalized rate suggestions for posts, stories, reels, and videos.
