Financial Models Skill
Core Philosophy
Know your numbers. Track revenue and expenses religiously. Make data-driven decisions. Aim for profitability, not just revenue.
Key Financial Metrics
Revenue Metrics
Monthly Recurring Revenue (MRR)
MRR = Number of Subscribers × Monthly Price
Stable, predictable income from subscriptions or retainers.
Annual Recurring Revenue (ARR)
ARR = MRR × 12
Used for annual planning and valuation.
Average Revenue Per User (ARPU)
ARPU = Total Revenue / Total Customers
Helpful for comparing segments and tracking growth.
Revenue by Stream
Track each revenue source separately:
- Sponsorships
- Digital products (courses, templates)
- Subscriptions
- Consulting
- Affiliate
Profitability Metrics
Gross Margin
Gross Margin = (Revenue - COGS) / Revenue × 100
For creators, COGS is typically low (platform fees, contractors).
Target: 70-90% for digital products, 60-80% for services
Net Profit Margin
Net Margin = (Revenue - All Expenses) / Revenue × 100
Target: 40-60% for lean operations (Justin Welsh achieves 90%+)
Operating Expenses
- Software/tools subscriptions
- Contractors/freelancers
- Marketing/advertising
- Professional services (legal, accounting)
- Education/training
Customer Metrics
Customer Acquisition Cost (CAC)
CAC = Total Marketing Spend / New Customers Acquired
Customer Lifetime Value (LTV)
LTV = ARPU × Average Customer Lifespan (months)
For subscriptions:
LTV = Monthly Price / Monthly Churn Rate
LTV:CAC Ratio
LTV:CAC = Customer Lifetime Value / Customer Acquisition Cost
Target: 3:1 or higher
- Below 1:1: Losing money on acquisition
- 1:1 to 3:1: Sustainable but tight
- 3:1+: Healthy, can invest in growth
Subscription Metrics
Churn Rate
Monthly Churn = Customers Lost / Starting Customers × 100
Benchmarks:
- <3% monthly: Excellent
- 3-5% monthly: Good
- 5-7% monthly: Needs attention
- 7%+ monthly: Problem
Retention Rate
Retention = 1 - Churn Rate
