6 Numbers Every Business Owner Should Know Cold By Sam's List | samslist.co You don't need to understand all of accounting to run a great business. But there are six numbers that should live in your head at all times—because they tell you, quickly and clearly, whether your business is healthy or headed toward a problem. Most business owners know their revenue. Fewer know their margins. Almost none can quote their cash conversion cycle or their break-even revenue off the vetted of their head. That gap between knowing you made money and knowing why your business is working is where the most expensive decisions happen. Number 1: Gross Margin Percentage Gross margin is the percentage of revenue left after paying the direct costs of producing your product or service. Formula: (Revenue − Cost of Goods Sold) / Revenue × 100 Example: $1M in revenue, $400K in COGS. Gross margin = 60%. Gross margin is the ceiling on your profitability. Every operating expense—salaries, rent, software, marketing—has to come out of your gross margin. If your gross margin is 30% and your operating expenses are 35% of revenue, you're losing money regardless of how much you grow. Compare your gross margin to your prior months and to industry benchmarks. A declining gross margin means your costs are rising faster than your prices, or your revenue mix is shifting toward lower-margin products. Either requires a response. If you can't quote your gross margin percentage right now, it's the first number to find. Number 2: Monthly Recurring Revenue (or Monthly Revenue Run Rate) For subscription and recurring-revenue businesses: Monthly Recurring Revenue (MRR) is the predictable revenue your business generates each month from active subscriptions or retainer clients. For project-based or variable-revenue businesses: Monthly Revenue Run Rate is your trailing 3-month average revenue, annualized. (Take the last 3 months of revenue, divide by 3, multiply by 12.) Knowing your run rate tells you where the business is trending, not just where it was. A business with $100K in revenue last month but a declining run rate is in a different position than one with the same monthly number and an accelerating trend. For businesses with recurring revenue, tracking MRR growth rate month over month is one of the most important established indicators of business health. A 5% monthly MRR growth rate compounds to 80% annual growth. A 2% monthly decline compounds to 22% annual decline. Number 3: Net Profit Margin Net profit margin is the percentage of revenue left after all costs—COGS, operating expenses, interest, and...
