The short answer: a profit and loss statement (P&L, or income statement) shows your sales, costs and profit over a period. Read it top to bottom: revenue at the top, cost of goods and expenses in the middle, and profit at the bottom. Each step tells you something different about the health of the business.
The key lines, top to bottom
- Revenue (sales) — total money from sales in the period.
- Cost of goods sold (COGS) — what the sold items cost you.
- Gross profit — revenue minus COGS.
- Operating expenses — rent, salaries, utilities, marketing.
- Net profit — what’s left after everything; the bottom line.
What each step tells you
- Revenue trend — are sales growing, flat or falling?
- Gross profit & margin — is your pricing and buying working? See gross vs net profit.
- Expense ratio — are overheads reasonable against sales?
- Net profit — the number that actually matters.
Read it as percentages, not just totals
Turn the big lines into percentages of revenue — gross margin, expense ratio, net margin. Percentages make months comparable and reveal trends a raw total hides. A hypothetical: revenue up 10% but net profit down usually means expenses or COGS grew faster than sales — the P&L shows exactly where.
Review it every month
The P&L is only powerful as a habit. A quick monthly read catches problems while they’re small — a slipping margin, a creeping expense — long before they become a crisis.
