Model Notes & Methodology
- ASSUMPTION All assumption inputs (yellow rows) are based on verified market data from 30+ sources including McKinsey, Gartner, MIT, Anthropic, and indie maker surveys. Modify these to fit your specific situation.
- SaaS MODEL Subscriber growth uses compound acquisition with monthly churn applied. Formula: Activen = (Activen-1 × (1 - churn)) + Newn. Churn rates benchmarked against Freemius Micro-SaaS 2025 report (median 5.4%).
- CONSULTING Utilization rate accounts for non-billable time (prospecting, admin, learning). Industry standard is 65-80% for independent consultants. Hours calculated as: weekly hrs × 4.33 weeks/month × utilization rate.
- API COSTS Based on Claude Haiku 4.5 ($1/$5 per 1M tokens) for SaaS use cases. Average request ~500 tokens input, ~500 tokens output = ~$0.003/request. At 50 requests/user/month = $0.15/user/month. Batch processing (50% discount) not applied in base case.
- TAXES All figures are pre-tax. Self-employment tax (US) is approximately 15.3% on net income. Federal + state income tax varies. For planning, assume 30-40% total effective tax rate on net income.
- SCALABILITY Consulting revenue is linearly bounded by available hours. SaaS revenue compounds with subscriber growth. Project-based scales with team size or efficiency. These structural differences matter more than Year 1 comparisons.
