About this calculator

Use this ad metrics calculator to recap a paid campaign from the figures in your ads manager. Enter spend, impressions, clicks, conversions, and the revenue you attribute to the ads. It is a recap of numbers you already have, not a live Ads API.

The formulas are: CPM = spend × 1000 ÷ impressions, CPC = spend ÷ clicks, CTR (%) = 100 × clicks ÷ impressions, CPA = spend ÷ conversions, and ROAS = revenue ÷ spend. ROAS is a ratio here (2 means two currency units back per unit spent), not a percent. If clicks, conversions, or spend are zero, the matching cost metric is returned as 0.

Spend: What you paid the platform in this period.

Impressions: How many times the ad was shown.

Clicks: How many clicks were billed or counted.

Conversions: Purchases or sign-ups you attribute to the ads. Use 0 if there were none.

Attributed revenue: Sales you attribute to the ads. Use 0 if you only care about costs.

CPM: Cost per thousand impressions.

CPC: Cost per click.

CTR (%): Clicks as a percent of impressions.

CPA: Cost per conversion.

ROAS: Attributed revenue divided by spend.
