Below 80%, within 80–120%, or above 120% of the reference. These are this tool's comparison bands, not industry quality grades.
Worked example
Illustrative YouTube calculation: 900 likes and 100 comments across two videos with 20,000 total views give 5.00% by views. With 5,000 subscribers, average interaction per video divided by subscribers gives 10.00%.
Illustrative inputs. Use your own measured data, confirmed prices and original work.Choose a platform and a denominator
Instagram starts with follower-based likes and comments, with optional shares and saves. TikTok supports views and followers with its selected interactions. YouTube uses likes and comments divided by views, or average interactions per video divided by subscribers.
Record the period and post count. If only one denominator is available, calculate that rate and keep its label when sending it to a brand.
Compare accounts without mixing formulas
Keep platform, denominator, included interactions, content type and reporting period consistent. A 5% YouTube rate by views and a 5% Instagram rate by followers have different meanings.
Cross-platform work benefits from a platform-by-platform summary. Do not add or average unrelated percentages into a single creator score.
What brands should check alongside engagement
Review audience location and relevance, typical reach, content quality, posting history and supplied analytics evidence. Read comments in context; a calculator cannot verify that the interactions or followers are genuine.
When the campaign goal is sales or enquiries, ask for the corresponding measured outcomes. Engagement is not a substitute for conversions, and high engagement does not establish a sponsorship price.
Connect measurement to AI influencer business
A virtual creator's social account can be measured with the same arithmetic. Describe the character as virtual, use actual published-account data and keep portfolio concepts separate from sponsored work.
Copy the labeled summary into a media kit, then price production, account posting and licensing as separate parts of the proposed collaboration.

Is this tool free without an account?
Yes. The calculations, prompt builder and document exports run in your browser without login or generation Credits.
Does the tool retrieve my social account?
No. Enter numbers from your own analytics or a public profile. The tool does not connect to Instagram, TikTok or YouTube.
Where is my draft saved?
Text drafts stay in this browser for seven days and can be cleared. Uploaded media stays locally. Export a copy before switching device or clearing browser data.
Which YouTube metrics are counted?
Likes and comments. You can divide their total by total views, or divide average interactions per video by subscribers. Dislikes, watch time and click-through rate are different metrics.
Can this detect fake followers?
No. Arithmetic on supplied numbers cannot verify audience authenticity. Review audience geography, comments, content history and analytics evidence separately.
Can I use the number to set a sponsorship price?
Use it as context alongside reach and audience fit. Price production, posting and usage rights separately using the rate calculator; an engagement percentage does not determine a fee.
