What it is
Customer/revenue concentration measures how much of total revenue is derived from a small number of customers. The standard regulatory threshold — requiring SEC disclosure — is any single customer representing more than 10% of revenue.
How to calculate it
Divide revenue attributable to your top N customers (or a single named customer) by total revenue for the period. The result is typically expressed as a percentage. The number of customers in "top N" is chosen based on materiality; SEC rules mandate disclosure when any single customer exceeds 10%.
Why it matters
High concentration is a key risk factor for investors: losing one large customer can dramatically impair revenue. For SaaS, usage, marketplace, and hardware businesses with enterprise sales motions, it is common to have meaningful concentration early, but investors expect it to decline as the customer base diversifies. Concentration also affects contract negotiating leverage and pricing power.
Benchmarks & pitfalls
There is no published aggregate band for this metric — it must be read per filing. The Snowflake S-1 (2020) illustrates the trajectory: Capital One represented approximately 17% of revenue in FY19, declining to approximately 11% in FY20, reflecting deliberate diversification. Because the metric is highly company- and stage-specific, comparisons across firms are limited. The primary pitfall is conflating revenue concentration with customer count — a company can have many customers but still have extreme revenue concentration among a few whales.
