About the CTR Calculator

CTR is treated here as a quantitative relation between Impressions, Clicks and Total Ad Spend and Click-Through Rate, Actual CPC and Clicks per 1,000 Impressions.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
CTR = (clicks / impressions) x 100
Actual CPC = total ad spend / total clicks
Clicks per 1,000 = CTR x 10

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

CTR = (clicks / impressions) x 100
Actual CPC = total ad spend / total clicks
Clicks per 1,000 = CTR x 10

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

impressions: 125000 clicks: 3950 ad_spend: 7450
Click-Through Rate: 3.16%. Actual CPC: $1.89. Clicks per 1,000 Impressions: 31.6

With Impressions = 125,000, Clicks = 3,950 and Total Ad Spend = 7,450 as the stated inputs, the result is Click-Through Rate = 3.16%, Actual CPC = $1.89 and Clicks per 1,000 Impressions = 31.6. Each value corresponds to the declared output fields.
