You do not need to memorize every account on your financial statements to understand how your business is performing. But there are a few numbers worth knowing because they can quickly tell you when something is changing.
The right measures vary by industry and business model, but these five are a practical starting point for many owner-managed businesses.
A useful number is not one you glance at once a year. It is one you understand, compare over time and use to make a decision.
1. Revenue
Revenue tells you how much the business is selling, but the useful question is what is happening underneath the total. Is revenue growing, shrinking or staying flat? Which customers, products or services are driving the change?
Revenue growth is encouraging, but it should always be considered alongside margin and cash flow.
2. Gross margin
Gross margin helps show how much is left after the direct costs of delivering your product or service. If sales are rising but gross margin is falling, growth may be getting more expensive.
Changes in material costs, subcontractors, labour, freight, merchant fees, pricing or product mix can all affect margin. Watching the percentage over time can reveal changes that total revenue hides.
3. Net profit
Net profit shows what remains after the broader costs of running the business. It helps answer a basic question: after everything required to operate the company, is the business actually creating earnings?
Compare profit with prior periods and with revenue. A business can become much busier without becoming more profitable if overhead grows too quickly.
