**Cost Assumptions:**
- Hosting: $200/mo → scales with traffic at ~$0.002/visitor
- Headcount: Founder only (Y1), +1 engineer (Y2), +2 (Y3)
- Marketing: 20% of revenue reinvested
**Unit Economics:**
- CAC: $15 (content/SEO driven, low paid spend)
- LTV: $360 (18 months × $20 ARPU)
- LTV:CAC ratio: 24:1
- Payback period: 0.75 months
**Sensitivity — Bear Case:**
- 50% lower traffic growth, 1.5% conversion = $180K ARR Y3
Usage Tips
- Document every assumption explicitly
- Use bottom-up not top-down for early stage
- Include bear case — investors will ask
- Update monthly with actuals vs. projections
