Logo Retention

Logo Retention is customer count math. It ignores revenue weighting entirely and asks one question: of the customers you had at the start of the period, how many are still customers at the end? A company can have 95% Gross Revenue Retention and 70% logo retention at the same time — the big accounts stayed, the small ones bled out. Both numbers are true. Only one is flattering.

How Logo Retention Is Calculated

The formula is brutally simple:

Logo Retention = (Customers at End of Period − New Customers Added) ÷ Customers at Start of Period

The denominator is locked at the start of the period — typically a quarter, year, or cohort. New logos acquired during the period are excluded from the numerator so the metric measures retention of the existing base, not net growth.

A 12-month logo retention calculation on a 500-customer base:

Note how new acquisitions are stripped out. The customer count at end of period is 625, but the relevant number for retention is 425 — the survivors from the starting cohort.

Worked Example

A B2B SaaS company starts the year with 200 customers across three segments:

• Enterprise: 20 customers averaging $250K ACV
• Mid-Market: 60 customers averaging $50K ACV
• SMB: 120 customers averaging $8K ACV

Over the year, they lose 1 enterprise customer, 6 mid-market customers, and 30 SMB customers.

• Enterprise logo retention: 19 ÷ 20 = 95%
• Mid-market logo retention: 54 ÷ 60 = 90%
• SMB logo retention: 90 ÷ 120 = 75%
• Blended logo retention: 163 ÷ 200 = 81.5%

Now look at revenue retention. The 37 lost customers represent $250K + $300K + $240K = $790K of lost ARR. The starting ARR base was $10.96M. GRR is $10.17M ÷ $10.96M = 92.8%.

A board deck that shows only the 92.8% GRR number hides the fact that the company is bleeding 25% of its SMB logos every year. That's an ICP problem, a product problem, or both — and it's invisible until you look at logo retention.

When Sales Teams Use Logo Retention

Logo retention is a CRO, CCO, and CFO metric. The CRO uses it to justify segment strategy — if SMB logo retention is 60% and enterprise is 95%, the upmarket motion is the future of the company. The CCO uses it to size customer success headcount and prioritize at-risk accounts. The CFO uses it because investors ask for it on every diligence call.

Recruiters use logo retention to read companies. A startup boasting 130% NRR but quietly running 75% logo retention is a land-and-expand machine that's losing the bottom half of its base. Sustainable. Sometimes. Not always.

Account executives feel it indirectly through territory shifts. When logo retention in a segment cliffs, that segment gets deprioritized, reps get moved upmarket, and the SMB hunters discover their book has been reassigned.

Common Logo Retention Gaming Patterns

The most common manipulation is logo definition gymnastics. When a customer downgrades from a $50K plan to a $5K plan, are they retained? Strict accounting says yes — they're still a logo. Aggressive accounting says yes loudly and points to the 95% logo retention number while quietly omitting the $45K of contraction. The retention number stays high while revenue per logo collapses.

A second pattern is multi-entity inflation. Selling to three business units of the same parent company counts as three logos. When one BU churns, two remain, and the "logo retention" looks stable even though the customer relationship deteriorated. Sophisticated investors ask for retention at the parent-account level, not the contract level.

A third pattern is the cohort cherry-pick. Companies report logo retention on their best cohort — typically the 12-month-old enterprise cohort where survivorship bias is strongest — and quietly omit the trailing 90-day SMB cohort where 40% of new signups churn before the first renewal.

Logo retention without revenue retention is half a picture. Revenue retention without logo retention is the other half. The companies that publish both are the ones telling the truth.
