Five Numbers Every Entrepreneur Must Know This Week

Revenue is the number every founder knows. It is the first thing they check, the number they share with pride, and often the only metric they track consistently. But revenue alone tells you almost nothing about the health of your business. A business doing R3 million in revenue with 15 percent margins is in worse shape than a business doing R1.5 million with 45 percent margins. A business growing at 40 percent year-on-year is not healthy if its customer acquisition cost exceeds its customer lifetime value. Revenue is the headline. These five numbers are the story.

The first number is your gross margin. This is your revenue minus the direct costs of delivering your product or service, expressed as a percentage. If you are a consulting firm, your direct costs are your consultants' time. If you are a product business, it is your cost of goods. Gross margin tells you how much money you actually keep from every rand of revenue before overheads. For service businesses in South Africa, a healthy gross margin sits between 50 and 70 percent. For product businesses, 30 to 50 percent is typical. If your gross margin is below these ranges, you have a pricing problem, a delivery efficiency problem, or both. This number should be on your dashboard, not buried in your annual financials.

The second number is your customer acquisition cost, or CAC. This is the total amount you spend on sales and marketing in a given period, divided by the number of new clients you acquired in that period. Include everything: advertising spend, sales team salaries, the cost of your time spent on business development. Most South African SME founders have never calculated this number, and when they do, they are surprised at how high it is. If you are spending R15 000 to acquire a client who generates R10 000 in gross profit over their lifetime, you are running an expensive charity, not a business.

The third number is customer lifetime value, or LTV. This is the total gross profit a client generates over the full duration of their relationship with your business. If your average client stays for 18 months and generates R5 000 in gross profit per month, your LTV is R90 000. The relationship between LTV and CAC is one of the most important ratios in business. A healthy business has an LTV to CAC ratio of at least 3:1. That means every rand you spend acquiring a client returns at least three rands in gross profit over time. If your ratio is below 3:1, you are either spending too much to acquire clients, not retaining them long enough, or not extracting enough value during the relationship.

The fourth number is your monthly burn rate. This is your total monthly operating expenses, including salaries, rent, software, marketing, and everything else that goes out whether or not revenue comes in. Burn rate matters because it tells you your runway: how many months your business can survive if revenue stopped tomorrow. For an established SME, you should have at least three months of expenses in reserve. For a business in growth mode, six months gives you the breathing room to take strategic risks without existential anxiety. If you do not know your burn rate to within R10 000, you are flying blind.

The fifth number is revenue per employee. Take your annual revenue and divide it by the total number of full-time equivalent staff, including yourself. This metric is a proxy for operational efficiency. It tells you whether you are generating enough value per person in your business, or whether you are overstaffed for your current revenue. In South Africa, benchmarks vary significantly by industry, but for professional services firms, R500 000 to R1 000 000 per employee is a reasonable target. For product businesses, it can be higher. If your revenue per employee is declining as you grow, your scaling is creating bloat, not leverage.

Each of these numbers tells a different story. Gross margin tells you about pricing and delivery efficiency. CAC tells you about the cost-effectiveness of your growth engine. LTV tells you about client relationships and retention. Burn rate tells you about financial resilience. Revenue per employee tells you about operational leverage. Together, they give you a multidimensional picture of business health that revenue alone cannot provide. A founder who tracks all five can make informed decisions about where to invest, where to cut, and what to fix first.

The Financial Health pillar of the Scale Readiness Audit is built around these concepts. It evaluates whether you have visibility into your key financial metrics, whether your pricing supports sustainable growth, and whether your financial management practices can support the next stage of scale. If you have never calculated some of these numbers, start this week. Open a spreadsheet, pull the data from the last three months, and run the calculations. You do not need an accountant for this. You need 30 minutes and the willingness to look at your business honestly.
