Compute impressions, clicks, and cost from CPM/CPC ad metrics. Planning estimates only — verify with production tools and vendor pricing where applicable. Impressions = (budget ÷ CPM) × 1000; clicks = budget ÷ CPC. Example: $1,000 budget at $5 CPM → 200K impressions; at $1 CPC → 1,000 clicks.

Impressions = (budget ÷ CPM) × 1000; clicks = budget ÷ CPC.
