How To Use This Heat Map

Enter total revenue and the approximate share held by your top 5 and next 15 customers.

The grid shows revenue by customer tier across three years, illustrating whether concentration in your largest accounts is increasing, a real risk factor buyers and lenders weigh heavily.

Your Inputs

Revenue Share, Top 5 Customers 35%

Revenue Share, Next 15 Customers (Rank 6-20) 25%

Concentration Trend

Buyers and lenders commonly flag a single customer above 15-20% of revenue, or a top-5 concentration above 50%, as a material risk factor worth specific disclosure and mitigation planning.
