Financial Statement Basics
## The Big 3 Financial Statements
### Income Statement (P&L) — "How much did we make?"
Revenue - COGS = Gross Profit
Gross Profit - OpEx = Operating Income
Operating Income - Taxes/Interest = Net Income
### Balance Sheet — "What do we own and owe?"
Assets = Liabilities + Equity
### Cash Flow Statement — "Where did the cash go?"
Operating + Investing + Financing = Net Cash Change
Key Ratios PMs Should Know
| Ratio | Formula | What It Tells You |
|---|---|---|
| Rule of 40 | Revenue Growth % + Profit Margin % | >40% = healthy SaaS |
| Magic Number | Net New ARR / Prior Quarter S&M | >0.75 = invest more in S&M |
| Burn Multiple | Net Burn / Net New ARR | <2x = efficient growth |
| Quick Ratio | (New MRR + Expansion) / (Contraction + Churn) | >4 = healthy |
