Advertising Frequency Formula

How to calculate frequency in advertising

Advertising frequency measures how many impressions were delivered, on average, to each person or account included in reported reach.

Frequency = Impressions ÷ Reach
500,000 impressions ÷ 200,000 reach =2.5 average frequency

How to calculate reach from impressions and frequency

Reach = Impressions ÷ Frequency
900,000 impressions ÷ 3.0 frequency =300,000 reach

Reach × frequency = impressions

Impressions = Reach × Frequency
250,000 reach × 4.0 frequency =1,000,000 impressions

Marketing reach calculator: what does reach mean?

Reach represents the number of unique people, accounts, households or other deduplicated entities estimated to have received at least one impression during the reporting period.

Platform reach is usually estimated.

Meta, Google, TikTok and other platforms can use different identity, deduplication and modelling methods. This calculator uses the mathematical relationship between the reported values you enter.

Is a high ad frequency bad?

Not automatically. Appropriate frequency depends on campaign objective, audience size, creative variety, buying method and campaign duration.

Frequency is a diagnostic signal, not an automatic pause rule.

Review frequency alongside CTR, CPA, ROAS, creative age and audience size before changing delivery.
