The Whale Curve
Most companies are shocked: 20% of clients generate 150-300% of total profit. Another 30% silently destroy it. The Whale Curve makes this visible – so you can act.
What Is the Whale Curve?
The Whale Curve is the visual output of a cumulative profitability analysis – ranking all clients (or products, channels) from most to least profitable and plotting the cumulative profit contribution. The resulting shape resembles a whale rising from the ocean.
The Peak
The highest point of the curve represents your total theoretical profit if you only served your best clients. This is the profit potential you are leaving unrealised.
The Decline
After the peak, the curve drops as unprofitable clients consume resources faster than they generate revenue – eroding margins invisibly.
The Tail
The bottom 30-40% of clients often represent net profit destruction. Serving them costs more than they pay – even when they appear to generate positive revenue.
Why Traditional Reporting Hides This
Standard P&L statements aggregate results. They show total margin, but hide which clients, products or channels are driving it – and which are destroying it. ABC / TDABC changes that by tracing actual activity costs to each client.
Full Cost Visibility
ABC assigns all overhead and support costs – logistics, customer service, rework, credit management – to the clients that actually consume them.
True Margin Per Client
Once true costs are allocated, you can rank clients by net contribution. The result is always surprising: top performers are more profitable than you thought; bottom ones, far worse.
Actionable Segmentation
With a complete Whale Curve, you can segment clients into Grow, Optimise, Reprice and Exit – and model the P&L impact of each decision before acting.
How We Build Your Whale Curve
We use ABC and Time-Driven Activity-Based Costing (TDABC) to build a precise, data-driven Whale Curve for your business. The process typically takes 5-25 working days depending on data availability.
Data Collection
We gather financial data, operational data and client transaction history. We map your cost structure and identify the main activity pools.
Cost Allocation
Using TDABC time equations, we allocate all indirect costs to clients based on actual resource consumption – not arbitrary volume-based drivers.
Whale Curve Output
You receive a full interactive profitability ranking, a visual Whale Curve, and a segmented client portfolio with recommended actions for each tier.
