Work out reach and frequency instantly with clear inputs, formula shown and shareable results.
Impressions divided by unique reach gives average frequency — how many times each person saw the message. Too low and the message does not register; too high and budget is wasted on people already convinced.
Reach and frequency
Frequency = impressions / reach; impressions needed = reach × target frequency
Figures are estimates based on the inputs given. Marketing performance, platform fees and conversion behaviour vary by audience, channel and season. Use this as a planning guide, not a forecast.
Three to five exposures is the classic guideline for recall, though it varies with message complexity and category.
Beyond the effective range it produces diminishing returns and can create irritation that damages the brand.
