Reading Your P&L Statement: What the Numbers Actually Tell You
Financial Planning · 2026-03-08 · 7 min
Your Profit and Loss statement tells a story about your business. Most owners focus on the bottom line and miss the insights hidden in the margins, trends, and ratios.
The Profit and Loss statement has three sections: revenue, cost of goods sold (COGS), and operating expenses. Revenue minus COGS gives you gross profit — the money left after delivering your product or service. Gross profit minus operating expenses gives you net profit — the money left after running the business.
Gross margin (gross profit divided by revenue) tells you how efficiently you deliver your product. If your gross margin is declining, you are either charging less or spending more on delivery. A services business should target 50-70% gross margin. A product business varies widely by industry. Track this monthly — it is the earliest indicator of pricing or cost problems.
Operating expenses fall into two categories: fixed (rent, salaries, subscriptions) and variable (marketing, travel, commissions). Fixed costs are predictable and create your break-even threshold. Variable costs should scale with revenue — if they grow faster than revenue, you have an efficiency problem.
The most useful P&L analysis is not a single month but a trend over 6-12 months. Look for revenue growth rate, margin trends, and the ratio of customer acquisition cost to lifetime value. A business with growing revenue but declining margins is buying growth at the expense of profitability — a pattern that does not end well.
