If you hang around at a startup event long enough, you’ll hear someone saying ARPU or CAC (no, they are not swearing.) Those are some of the metrics that show how well (or bad) a business is doing.  

But for many, understanding which metrics matter, how to measure them, what to do with them in the early stages, and finally, how to benchmark themselves against them is a bit of a myth.  

get them right…make it rain

So today, we are diving into key metrics for a B2B SaaS business in South Africa and how to use these metrics to determine where you should focus your efforts.

🇿🇦 Sign up to The Open Letter Pro to see how to calculate these metrics; use this metric specifically in the local South African setting PLUS a benchmark calculation to measure your progress.

1. YoY ARR growth: Tracking Expansion and Investor Appetite

Why it matters: YoY ARR Growth indicates how well your startup is expanding its customer base and revenue, which is crucial for attracting investors. Consistent growth in ARR shows that your business is scaling effectively and that there is increasing demand for your product or service.

2. Gross Rand Retention: Assessing Customer Loyalty and Product Effectiveness

Why it matters: Gross Rand Retention helps assess the loyalty of your customer base and the effectiveness of your product or service. High retention rates suggest satisfied customers who see value in what you offer, reducing churn and promoting long-term revenue stability.

3. Net Rand Retention: Measuring Revenue Growth Potential from Existing Customers

Why it matters: NRR provides insights into your revenue growth potential from your existing customer base. By including upsells and cross-sells, this metric highlights your ability to expand revenue from current customers, which is often more cost-effective than acquiring new ones.

4. Gross Margin-Adjusted CAC Payback: Assessing Customer Acquisition Cost Efficiency

Why it matters: This metric tracks how long it takes to recoup customer acquisition costs based on gross margin. It helps you understand the efficiency of your spending on acquiring new customers and how quickly those investments are paying off.

5. Magic Number: Measuring Sales and Marketing Efficiency

Why it matters: The Magic Number measures the efficiency of sales and marketing spending in driving new revenue. A higher Magic Number indicates that your sales and marketing efforts are yielding significant returns, which is vital for scaling your business.

6. Rule of 40: Balancing Growth and Profitability

Why it matters: The Rule of 40 combines growth rate and profit margin to assess overall business health. A Rule of 40 score above 40% suggests a balanced approach to growth and profitability, making your startup more attractive to investors.

7. Revenue Burn Multiple: Evaluating Capital Efficiency

Why it matters: The Revenue Burn Multiple indicates how efficiently a startup is using its capital to generate revenue. A lower multiple suggests better capital efficiency, which is crucial for sustainability and growth, especially in the early stages.

8. ARR per FTE: Measuring Employee Productivity

Why it matters: ARR per FTE measures productivity by calculating ARR per employee. It helps you understand how effectively your team contributes to revenue generation, guiding decisions on hiring and resource allocation.
