No API needed — just numbers and formulas.\n\n## Core Formulas\n\n| Metric | Formula | Example |\n|--------|---------|---------|\n| **CPA** | Cost ÷ Conversions | $5,000 ÷ 100 = **$50** |\n| **ROAS** | Revenue ÷ Cost | $15,000 ÷ $5,000 = **3.0x** |\n| **CTR** | (Clicks ÷ Impressions) × 100 | (350 ÷ 10,000) × 100 = **3.5%** |\n| **CPC** | Cost ÷ Clicks | $5,000 ÷ 350 = **$14.29** |\n| **CVR** | (Conversions ÷ Clicks) × 100 | (100 ÷ 350) × 100 = **28.6%** |\n| **CPM** | (Cost ÷ Impressions) × 1,000 | ($5,000 ÷ 10,000) × 1,000 = **$500** |\n\n## Budget Projections\n- **Monthly projection** = (MTD Spend ÷ Days Elapsed) × Days in Month\n- **Remaining budget** = Daily Budget × Days Remaining\n- **Break-even ROAS** = 1 ÷ Profit Margin (e.g., 40% margin → 2.5x ROAS)\n- **Target CPA** = Customer Lifetime Value × Acceptable CAC Ratio\n\n## Impression Share Math\n- **Impression Share** = Impressions ÷ Eligible Impressions\n- **Missed impressions** = (Impressions ÷ IS) - Impressions\n- **Cost to capture missed IS** = Missed Impressions × (Current Cost ÷ Current Impressions)\n\n## Google Ads API\n- **cost_micros** ÷ 1,000,000 = actual dollars\n- 45000000 = $45.00 | 1500000 = $1.50 | 100000000 = $100.00\n\n## Benchmarks\n\n| Metric | Search | Shopping | Display | YouTube |\n|--------|--------|----------|---------|---------|\n| CTR | 3-5% | 1-2% | 0.5-1% | 0.5-2% |\n| CVR | 3-8% | 1-3% | 0.5-1% | 0.5-1% |\n| CPC | $1-15 | $0.30-1.50 | $0.30-2 | $0.05-0.30 |\n\n## Rules\n- ALWAYS show your work (formula + numbers + result)\n- ALWAYS include the unit (%, $, x)\n- Round to 2 decimal places\n- When given cost_micros, convert FIRST then calculate","tags":["google","ads","math","miniagent","itallstartedwithaidea","advertising","agent-skills","ai-agents","claude-code","cross-platform","google-ads","llm"],"capabilities":["skill","source-itallstartedwithaidea","skill-google-ads-math","topic-advertising","topic-agent-skills","topic-ai-agents","topic-claude-code","topic-cross-platform","topic-google-ads","topic-llm","topic-mcp","topic-meta-ads","topic-minimind","topic-model-context-protocol","topic-ollama"],"categories":["MiniAgent"],"synonyms":[],"warnings":[],"endpointUrl":"https://skills.sh/itallstartedwithaidea/MiniAgent/google-ads-math","protocol":"skill","transport":"skills-sh","auth":{"type":"none","details":{"cli":"npx
