GRR
Gross Revenue Retention — the percentage of recurring revenue retained from existing customers over a period, excluding expansion revenue. Unlike NRR, GRR can never exceed 100%.
GRR (Gross Revenue Retention) measures how much of a company's recurring revenue is retained from an existing customer cohort, counting only churn and contraction — not expansion. It represents the baseline retention floor before any upsells or cross-sells.
Formula: GRR = (Beginning ARR − Churn − Contraction) / Beginning ARR × 100
Because expansion revenue is excluded, GRR can never exceed 100%. It answers the question: 'How much of last year's revenue did we keep, ignoring any growth?'
Benchmarks by segment: - Enterprise SaaS: >90% is excellent, 85–90% is acceptable - SMB SaaS: >80% is good, 75–80% is acceptable (SMB inherently churns more) - Consumer subscriptions: 70–80% is typical
GRR is the 'floor' of a business — it shows what you're naturally keeping before growth efforts.
In Practice
A company has $10M ARR from existing customers at year start. By year end, $800K churned out and $200K downgraded, but no expansions. GRR = ($10M − $800K − $200K) / $10M = 90%. This business has strong gross retention even before upsells are counted.
Why It Matters
GRR reveals whether the core product is sticky enough to retain customers on its own — without the sales motion of upselling. A business with 95% GRR has a fundamentally healthy customer base. A business with 70% GRR must run to stand still: it needs to constantly acquire new customers just to replace what it's losing. Low GRR often signals product-market fit problems or a weak customer success function.
VC Beast Take
Many founders conflate GRR and NRR. The key difference: NRR can mask a broken GRR with strong upsell performance. A company with 75% GRR and 110% NRR is in a dangerous position — it's expanding accounts faster than it's losing them, but the underlying churn is a ticking clock. If upsell slows, the whole revenue structure unravels. Strong businesses need both high GRR (keep customers) and high NRR (grow them).
