Customer penetration and revenue share need not match.
Customer penetration measures how much of a buying population you serve. Revenue share measures how much of its spend you capture. The two differ when your customers are larger, smaller or use more products than the market average.
Market boundaries must match across numerators and denominators. Company-wide revenue cannot be compared with a single-country market unless the numerator is narrowed to that country.
The formula, made clear.
- Customer penetration
- A share of comparable buying units.
- Revenue share
- A share of comparable annual spend, not a share of customer logos.
Put the numbers in context.
1,000 of 20,000 serviceable customers gives 5% penetration. Annual revenue of 2.4 million in a 48 million market also gives 5% revenue share.
| Input | Example value |
|---|---|
| Your active customers | 1,000 customers |
| Serviceable customer population | 20,000 customers |
| Your annual market revenue | $2,400,000.00 |
| Serviceable annual market revenue | $48,000,000.00 |
| Customer penetration | 5% |
What this calculation assumes
Matching scope, period and buying units. Numerators cannot exceed the supplied market. Multi-vendor purchasing may make customer populations overlap across competitors, so penetration does not sum cleanly across vendors.
What to consider next.
If revenue share differs from customer penetration, inspect customer size, product mix and wallet share.
