How Do You Calculate Cost Per Impression?

Divide what you spent by the impressions you received. That gives cost per impression. Multiply it by 1,000 and you have cost per 1,000 impressions, the figure every ad platform reports, often shortened to CPM. Spend AED 5,000, receive 250,000 impressions, and the cost per impression is AED 0.02, which is AED 20 per thousand. To plan the other way round, divide your budget by your cost per 1,000 and multiply by 1,000 to forecast the impressions it buys. An impression is a showing, not a person: reach counts the audience, and impressions divided by reach gives frequency. There is no universal normal figure, because country, placement, audience size, season, creative quality, objective and language all move the price. Read your result first, at the ad set level, then use the impression price to explain why it moved.
