Estimate Your Hidden Losses

Enter your basic business metrics to see an estimate of how much profit your tail customers may be destroying annually.

How We Calculate This

This estimate is based on profit curve research that shows customer profitability is heavily skewed:

•Top 20% of customers typically generate 150-200% of total profits
•Bottom 10-30% often destroy 20-50% of those profits
•Industry benchmarks vary, but 15-25% tail drag is typical

These are directional estimates. Your actual numbers may be higher or lower depending on your business model, pricing structure, and customer mix.

The Profit Curve Effect

Named after the shape it creates when you chart cumulative profit by customer, the profit curve reveals that most businesses have customers that:

Top Customers (Head)

High-profit customers who drive disproportionate value

Middle

Marginally profitable customers who cover their costs

Tail

Unprofitable customers who consume more than they generate

Based on Industry Research
