Reading the Three Financial Statements
Every invoice, every bill, every reconciliation, every adjusting entry you’ve made exists to produce three reports. Lenders read them, buyers read them, and the IRS cross-checks them. This chapter teaches you to read them like an owner.
The Profit & Loss statement
The P&L answers the book’s first question: am I actually making money? It covers a period — a month, a quarter, a year — and flows like this: revenue minus cost of goods sold gives gross profit; minus operating expenses gives operating income; adjusted for other income and taxes gives net income.
Take a catering business. Revenue of $320,000 minus food and supply costs of $112,000 leaves a gross profit of $208,000 (65% gross margin). Operating expenses total $184,000 — wages $110,000, rent $36,000, insurance $9,000, vehicle $12,000, advertising $6,000, other $11,000. That leaves a net income of $24,000.
Read it three ways. First, trends over single numbers: $24,000 profit means something very different if last year was $60,000 — a decline to investigate. Second, percentages: every line as a share of revenue — food cost 35%, wages 34%, rent 11%. Percentages reveal drift dollars hide; if food cost creeps from 32% to 38% over a year, pricing or purchasing has a problem even as revenue grows. Third, separate signal from noise: note one-time items and compare the underlying business, not the accidents.
The Balance Sheet
The balance sheet is the accounting equation on a page, frozen at a single moment — “as of December 31.” Assets on one side; liabilities and equity on the other; both sides always equal.
Our caterer at year-end: assets of $96,000 (cash $28,000, receivables $14,000, inventory $9,000, equipment net of depreciation $45,000); liabilities of $33,000 (payables $8,000, credit card $3,000, equipment loan $22,000); equity of $63,000 (owner’s capital $39,000, retained earnings $24,000). Check: $96,000 = $33,000 + $63,000.
It’s a snapshot, not a movie — always read at least two periods side by side. Watch working capital — current assets minus current liabilities — because positive working capital means the business can cover near-term obligations, and shrinking working capital is an early warning. And watch equity: it grew by the $24,000 profit (minus any draws), and year after year retained earnings should compound. If equity is flat or shrinking, the balance sheet disagrees.
The Cash Flow Statement
The P&L can show a profit while the bank account empties — profit includes non-cash items like depreciation and ignores timing (a big invoice recorded as income but not yet collected). The cash flow statement reconciles profit to actual cash in three sections:
- Operating activities: cash from running the business — collections from customers minus payments to suppliers, employees, and tax authorities.
- Investing activities: cash spent on or received from long-term assets — buying equipment (out), selling the old van (in).
- Financing activities: cash from or to lenders and owners — loan proceeds (in), repayments (out), owner contributions (in), draws (out).
Our caterer earned $24,000 of net income, but receivables grew by $6,000 and she bought $15,000 of equipment — so operating cash flow might be only $12,000, and total cash actually fell. The P&L says “profitable year”; the cash flow statement says “here’s where the cash went.” Both are true. You need both.
How the three connect
The statements are one linked system: the P&L’s net income flows into the balance sheet’s retained earnings; the balance sheet’s balances explain the cash flow statement, which shows why cash moved between the two dates; next period’s P&L starts fresh while the balance sheet carries forward.
Three ratios every owner should know
- Gross margin = (Revenue − COGS) ÷ Revenue. Our caterer: ($320,000 − $112,000) ÷ $320,000 = 65%. It measures whether the core business model works — are you charging enough relative to cost? Track it monthly; a declining gross margin is the earliest sign of pricing or cost trouble.
- Current ratio = Current Assets ÷ Current Liabilities. Our caterer: $51,000 ÷ $11,000 ≈ 4.6. It measures short-term survival. Above 1.0 is the comfort zone; below 1.0 means you’re counting on future sales to pay current bills.
- DSO (Days Sales Outstanding) = (Receivables ÷ Annual Revenue) × 365. Our caterer: ($14,000 ÷ $320,000) × 365 ≈ 16 days. It measures how fast you collect. Lower is better; compare it to your payment terms — Net-30 terms with a 55-day DSO means customers pay nearly a month late on average.
Ratios mean nothing in isolation. Their power is in trends: this quarter vs. last, this year vs. last, your business vs. your industry’s norms.
Red flags on each statement
On the P&L: gross margin declining over several periods (pricing isn’t keeping up with costs); an expense growing much faster than revenue; profit without cash, persistently (receivables or inventory are eating the business alive).
On the balance sheet: receivables growing faster than revenue (selling more, collecting worse); negative or shrinking equity (the business is consuming its own foundation — lenders notice immediately); debt growing while cash shrinks (borrowing to cover shortfalls, not to invest).
On the cash flow statement: operating cash flow negative while net income is positive, period after period (profitable-looking but bleeding cash from operations); growth funded entirely by debt or owner contributions (if operations never produce cash, the business model is the problem).
None of these is a verdict by itself. Each is a question: why is this happening, and what do we do about it?
The 10-minute monthly review
After each monthly close, give the statements ten focused minutes. Minutes 1–3: the P&L — compare to last month and the same month last year, note revenue trend, gross margin, and any line that moved unexpectedly. Minutes 4–6: the balance sheet — check cash, receivables, and payables, and confirm equity moved the way the P&L says it should. Minutes 7–10: cash flow and ratios — did operating cash flow track profit, and where are your three ratios trending? Then write three sentences: what happened, why, and what you’ll watch next month. Twelve of those memos is a year’s worth of business intelligence.
Key takeaways
- The P&L shows profit over a period — read it in trends and percentages, and separate one-time items from the underlying business.
- The balance sheet is the accounting equation frozen in time — compare at least two periods side by side, and watch working capital and equity growth.
- The cash flow statement reconciles profit to cash in three sections — operating, investing, financing — and explains where the money actually went.
- The three statements link together: net income feeds retained earnings, and balance sheet changes explain cash movement.
- Know three ratios — gross margin (does the model work?), current ratio (can we survive the short term?), DSO (how fast do we collect?) — and track their trends.
