Per-Customer Cost: SEO Roast ($0.50/request)
When a customer buys our SEO Roast tool for $47, it triggers one Claude API call. Here is what that call costs us:
- Input tokens: ~15,000 (site analysis + detailed prompt)
- Output tokens: ~8,000 (detailed roast report)
- Input cost: 15,000 / 1,000,000 × $3 = $0.045
- Output cost: 8,000 / 1,000,000 × $15 = $0.12
- Total API cost per customer: ~$0.165 (let us call it $0.17 to account for variability)
We charge $47. Our gross margin on API cost alone is 99.6%. This is why unit economics matter more than total cost.
