Profitability Visibility
Know which customers, products and channels make money — and which are quietly destroying value.
What is Profitability Visibility?
Profitability visibility is the ability to see net profitability — revenue minus all costs — at the level of individual customers, products, services, or channels. The famous Whale Curve analysis typically shows that 20-30% of customers generate 150%+ of total profit, while the tail destroys value.
Why It Matters
Without granular profitability data, businesses grow revenue while unknowingly eroding margin. Sales teams win unprofitable deals. Pricing is intuitive rather than cost-informed. And strategic decisions are made on aggregate numbers that mask underlying reality.
Maturity Levels
Where does your organisation stand?
Blind
P&L available only at company level. No product or customer profitability view.
Partial
Gross margin by product or business unit. No full cost-to-serve visibility.
Structured
Net margin by product and key customer segments. Some overhead allocation.
Full Visibility
Whale Curve analysis. Full net profitability by customer, product and channel.
How to Improve
Segment Your Portfolio
Define the dimensions you want to measure: customers, products, channels, geographies. Start with what drives most revenue.
Allocate All Costs
Apply full cost allocation — including overhead, support, and indirect costs — to each segment using activity-based logic.
Build the Whale Curve
Rank customers or products by cumulative profit contribution. Identify your profit makers, break-even accounts, and value destroyers.

Frequently Asked Questions
What is the Whale Curve?
The Whale Curve is a visualisation of cumulative profitability when customers are ranked from most to least profitable. The curve typically peaks well above 100% of total profit, then descends as loss-making customers erode the total.
How many customers are typically unprofitable?
Research consistently shows that 40-60% of customers are unprofitable when full costs are allocated. Yet most businesses have no visibility into which ones — and continue serving them at the same cost.
Can I get profitability visibility without a full TDABC model?
You can get partial visibility with simpler methods, but the accuracy is limited. A TDABC model gives you reliable profitability data that you can act on with confidence.
What should I do with unprofitable customers?
Not all unprofitable customers are equal. Some have strategic value or growth potential. The goal is to understand root causes — is it pricing, complexity, or volume? — and then decide: reprice, simplify, or exit.
