The target scenario holds impressions constant. It is arithmetic, not a prediction of future clicks.
Three formulas, one consistent measurement window
CTR describes the share of recorded impressions that produced clicks. Keep the source and date range aligned before interpreting it.
Solve for CTR
CTR = clicks ÷ impressions × 100. The result keeps four decimal places for small rates.
Solve for clicks
Clicks = impressions × CTR ÷ 100. Fractional output is mathematical; real observed clicks are whole events.
Solve for impressions
Impressions = clicks ÷ (CTR ÷ 100). Compare only definitions that match across platforms.
