Four critically important KPIs

tiemadmin • 9 June 2025

Gross profit margin
This measures the profitability of your core operations by comparing gross profit (sales minus cost of goods sold) to total revenue. A stable or improving gross margin indicates pricing, production, or service delivery is efficient. A declining margin may signal rising costs or pricing issues.

Formula: (Gross Profit ÷ Revenue) × 100

Cash flow
Positive cash flow ensures a business can meet its obligations, pay suppliers and staff, and invest in growth. Even profitable businesses fail without adequate cash. Tracking cash flow (operating, investing, and financing activities) helps prevent liquidity crises.

Monitor: Monthly net cash inflow/outflow and rolling 3-month cash forecast

Customer acquisition cost (CAC)
This shows how much it costs to acquire a new customer. If CAC is rising without a corresponding increase in customer value or retention, it can drain profitability. Ideally, CAC should be lower than the revenue generated by each customer over their lifetime.

Formula: Total Sales and Marketing Costs ÷ Number of New Customers

Net profit margin
This is the bottom line—what remains after all costs, taxes, and interest. It reflects overall efficiency and financial viability. A strong net margin gives room for reinvestment and debt servicing, and signals long-term sustainability.

Formula: (Net Profit ÷ Revenue) × 100
