Formula Used
Reach Rate (%) = (Unique Reach ÷ Selected Base) × 100 Frequency = Impressions ÷ Unique Reach Engagement Rate on Reach (%) = (Engagements ÷ Unique Reach) × 100 Share Rate on Reach (%) = (Shares ÷ Unique Reach) × 100This calculator uses deduplicated unique reach as the main numerator. You can compare that reach against followers, impressions, or an addressable audience depending on the reporting question.
Followers mode shows community penetration. Impressions mode shows how efficiently delivery translated into unique people. Audience mode estimates how much of an available market the campaign touched.
Frequency helps interpret repetition, while the additional rates show how well the reached audience interacted and shared the content.

FAQs
1. What does reach rate measure?
Reach rate measures the percentage of a chosen base that saw your content. The base can be followers, impressions, or an estimated audience segment, depending on your reporting goal.
2. Why is unique reach better than impressions for this metric?
Unique reach removes repeated exposures to the same person. That makes the main percentage more useful when you want to know how many distinct people actually saw the campaign.
3. When should I use followers as the denominator?
Use followers when you want to know how much of your existing community saw the content. It works well for page performance, subscriber visibility, and organic distribution reviews.
4. When should I use impressions as the denominator?
Use impressions when you want to compare delivery volume against unique audience coverage. It helps highlight repetition, overexposure, and whether the campaign is serving the same users too often.
5. What is frequency in this calculator?
Frequency is the average number of impressions delivered per unique person reached. Higher frequency means more repeated exposure, which can help recall but may reduce efficiency.
6. Why can organic and paid source totals exceed unique reach?
The same person may be reached through both organic and paid delivery. When that happens, source totals can be higher than deduplicated unique reach because overlap exists between channels.
7. What does unreached base mean?
Unreached base shows how much of the selected denominator did not see the content. It is useful for estimating remaining follower coverage or untapped audience potential.
8. Can I use this for paid and organic campaigns together?
Yes. Enter total unique reach for the combined campaign, then add optional organic and paid reach values to review mix, source coverage, and efficiency metrics in one report.
