- Enter total impressions. Use all counted content exposures for the campaign or reporting period.
- Enter average frequency. This is the average number of impressions delivered per reached account.
- Review estimated reach. The calculator divides impressions by frequency to estimate unique accounts.
- Inspect repeat exposure. The supporting result shows impressions beyond the first estimated exposure per account.
- Confirm scope alignment. Both inputs must come from the same campaign and date range.
TikTok Reach Calculator
The TikTok Reach Calculator estimates unique accounts reached from total impressions and an average frequency. Reach counts distinct accounts, while impressions count all exposures, including repeat views by the same account.
Use this estimate when a report provides impressions and frequency but does not directly provide reach. The result is most useful for campaign planning and consistency checks. It assumes the entered average frequency accurately represents how impressions were distributed across unique accounts.

Estimated reach = Total impressions ÷ Average frequency
Repeat impressions = Total impressions − Estimated reach
Average frequency is impressions per reached account. This rearranges the standard relationship: Impressions = Reach × Frequency.
What the result means
The result estimates how many unique accounts were exposed to the content.
It is an estimate when reach is not directly measured; rounding and platform definitions can produce differences.
Given: 780,000 impressions and an average frequency of 1.6.
Calculation: 780,000 ÷ 1.6 = 487,500 estimated reached accounts. Repeat impressions = 780,000 − 487,500 = 292,500.
Result: Estimated unique reach is 487,500 accounts.
The campaign delivered an average of 1.6 impressions to each reached account.
Is reach the same as views?
Not necessarily. Reach is generally a unique-account measure, while views may include repeat viewing and can follow different counting rules.
What if frequency is below 1?
An average frequency below 1 is usually inconsistent with the basic impressions-per-reached-account definition. Recheck the source and units.
Can I calculate organic and paid reach together?
Only when impressions and frequency are combined using a compatible method. Overlap between organic and paid audiences can make simple addition inaccurate.
Why might estimated reach differ from the platform report?
The platform may use unique-account modeling, privacy thresholds, deduplication, or rounding that is not captured by this simple formula.
How is reach different from impressions?
Reach counts distinct accounts exposed. Impressions count every exposure, so one account can contribute several impressions.
