Most founders track revenue. Many track profit. Few track the metrics that actually predict whether their business is healthy, scaling sustainably, and headed in the right direction.
Here are the seven KPIs I build into every management dashboard — and why each one matters.
1. Gross Margin
What it is: Revenue minus the direct cost of delivering your product or service, expressed as a percentage of revenue.
Why it matters: Gross margin tells you how efficient your core business model is. A high gross margin means more of every pound of revenue flows through to cover overheads and generate profit. A low or declining gross margin is often the first signal of pricing pressure, cost creep, or a business model problem.
How to calculate it: (Revenue − Cost of Goods Sold) ÷ Revenue × 100
What good looks like: Highly variable by industry. SaaS businesses often target 70-80%+. Professional services firms typically run 40-60%. Product businesses may be 30-50%. The key is understanding your own trajectory — is margin stable, improving, or eroding?
2. Monthly Recurring Revenue (MRR) / Annual Recurring Revenue (ARR)
What it is: The predictable, contractually committed revenue you can count on each month or year.
Why it matters: Recurring revenue is the most valuable kind. It gives you predictability, reduces the cost of sales, and is weighted heavily by investors in any valuation. If you have subscription or retainer revenue, you should be tracking this obsessively.
How to calculate it: Sum of all active monthly subscription or retainer fees (MRR). Multiply by 12 for ARR.
3. Net Revenue Retention (NRR)
What it is: The percentage of revenue retained from your existing customer base over a period, accounting for churn, downgrades, and expansions.
Why it matters: NRR above 100% means your existing customers are spending more over time — even without acquiring a single new customer, your revenue would grow. It’s one of the most powerful indicators of product-market fit and customer satisfaction.
How to calculate it: (Starting MRR + Expansion MRR − Churned MRR) ÷ Starting MRR × 100
4. Customer Acquisition Cost (CAC)
What it is: The total cost of acquiring a new customer, including sales and marketing expenses.
Why it matters: If it costs you more to acquire a customer than they’re worth, no amount of revenue growth will save you. CAC is the unit economics metric that tells you whether your go-to-market machine is efficient.
How to calculate it: Total Sales & Marketing Spend ÷ Number of New Customers Acquired (in the same period)
5. Customer Lifetime Value (LTV)
What it is: The total revenue you expect to generate from a customer over the entire relationship.
Why it matters: On its own, LTV is useful. In relation to CAC, it’s essential. An LTV:CAC ratio of 3:1 or higher is generally considered healthy. Below 1:1 means you’re destroying value with every customer you acquire.
How to calculate it: Average Revenue per Customer × Gross Margin % × Average Customer Lifetime (in years)
6. Cash Runway
What it is: How many months your business can operate at its current burn rate before running out of cash.
Why it matters: Cash runway is existential. Every business decision — hiring, investment, pricing — should be made with an eye on runway. The goal isn’t just to know the number today, but to forecast it three, six, and twelve months out.
How to calculate it: Current Cash Balance ÷ Monthly Net Cash Burn
7. Revenue per Employee
What it is: Total annualised revenue divided by total headcount (including contractors).
Why it matters: This is a simple but powerful measure of organisational efficiency. As you scale, you want revenue per employee to improve or hold steady — if headcount is growing faster than revenue, that’s a warning sign worth examining.
How to calculate it: Annual Revenue ÷ Total Headcount
The bottom line
You don’t need to track all seven from day one. Start with the three or four most relevant to your business model, get them into a monthly dashboard, and build from there. The goal isn’t more data — it’s the right data, reviewed consistently, leading to better decisions.
