What is GRR?
Gross Revenue Retention (GRR) is the SaaS metric that measures the percentage of recurring revenue retained from existing customers over a defined period (typically 12 months), excluding any upsell or expansion revenue. GRR isolates pure churn and contraction — answering the question “how much revenue do we keep before considering growth from existing accounts?” GRR is capped at 100% (you cannot retain more than you started with on a gross basis) and serves as the floor of customer health metrics.
GRR formula
GRR = (Starting MRR – Churned MRR – Contraction MRR) / Starting MRR × 100
- Starting MRR: recurring revenue from existing customers at period start.
- Churned MRR: revenue lost from customer cancellations.
- Contraction MRR: revenue lost from downgrades, seat reductions, or plan changes.
- Excludes: upsell, cross-sell, price increases (those go into NRR calculation).
GRR benchmarks by segment
- SMB SaaS: 80-90% GRR typical; higher churn due to business volatility.
- Mid-market SaaS: 88-93% GRR typical.
- Enterprise SaaS: 92-97% GRR typical; longer contracts and higher switching costs.
- Best-in-class: 95%+ GRR across all segments signals strong product-market fit.
GRR diagnostics
- Cohort analysis: GRR by customer segment, ARR band, signup year reveals where attrition concentrates.
- Logo vs. revenue retention: distinguish customer count retention from revenue retention.
- Voluntary vs. involuntary: separate cancellations (product/fit issues) from payment failures (billing ops).
- Time-to-churn: early-cohort churn signals onboarding issues; late-cohort churn signals deeper engagement gap.
Türk SaaS pazarında
Türk SaaS şirketleri (Insider, Foriba, Logo, Loops AI) için GRR makro volatilite (TL kur, enflasyon) tarafından etkilenir — özellikle TL-fiyatlı ürünlerde müşterilerin bütçe sıkışıklığı kontraksiyon yaratır. USD-fiyatlı uluslararası satışlarda GRR Türk yerel müşterilerden tipik olarak daha yüksek. Pratikte Türk SaaS’lerin yatırımcı raporlamasında GRR + NRR + Net New ARR combo Magic Number ile birlikte standart KPI setidir.
Do: calculate GRR monthly with cohort granularity; investigate sudden drops with customer success interviews; benchmark against segment peers.
Don’t: include expansion in GRR — it inflates the metric and hides churn problems; report GRR and NRR side-by-side for full picture.
