Core Metrics

CPM (Cost per Mille) = Spend / Impressions × 1000 "Cost per 1,000 impressions" CPC (Cost per Click) = Spend / Clicks CTR (Click-Through Rate) = Clicks / Impressions × 100 CPA (Cost per Acquisition) = Spend / Conversions ROAS (Return on Ad Spend) = Revenue / Spend Clicks = Impressions × CTR / 100 Impressions = Budget / CPM × 1000 Spend = CPM × Impressions / 1000

Funnel Calculations

Impressions = Budget / CPM × 1000 Clicks = Impressions × CTR / 100 Conversions = Clicks × CVR / 100 Revenue = Conversions × Revenue per Conversion Gross Profit= Revenue × Gross Margin / 100 Marketing ROI = (Gross Profit - Spend) / Spend × 100 Example: ₹1,00,000 budget, CPM ₹150, CTR 1.5%, CVR 3% Impressions = 1,00,000 / 150 × 1000 = 6,66,667 Clicks = 6,66,667 × 0.015 = 10,000 Conversions = 10,000 × 0.03 = 300 Revenue = 300 × ₹2,500 = ₹7,50,000 ROAS = 7,50,000 / 1,00,000 = 7.5×

ROAS vs Marketing ROI

ROAS = Revenue / Spend (Does not account for product cost) Marketing ROI = (Revenue × Margin% - Spend) / Spend × 100 (True profitability after product cost) Example: Spend ₹50K, Revenue ₹2L, Margin 40% ROAS = 2,00,000 / 50,000 = 4× Marketing ROI = (2,00,000×0.4 - 50,000)/50,000 = (80,000 - 50,000)/50,000 = 60% Break-even ROAS = 1 / Gross Margin% At 40% margin: break-even ROAS = 1/0.40 = 2.5×
