Gross Revenue Retention (GRR)

Gross Revenue Retention (GRR)

Gross Revenue Retention (GRR) measures the percentage of recurring revenue you retain from your existing customers over a period, excluding any expansion (upsell/cross-sell) revenue. It answers the question:

Of the recurring revenue I started the period with, how much did I keep?

Because expansion is excluded, GRR can never exceed 100%.

How to Calculate GRR

Formula:

GRR = (Beginning ARR − Contraction ARR − Churned ARR) / Beginning ARR × 100

Where:

• Beginning ARR: Recurring revenue from existing customers at the start of the period.
• Contraction ARR: Revenue lost from downgrades, seat reductions, or price decreases (customers still active).
• Churned ARR: Revenue lost from customers who fully cancel.

Because expansion ARR is excluded, the metric purely reflects losses from churn and contraction.

GRR vs. NRR

• GRR (Gross Revenue Retention)
• Focus: How much revenue you kept from your starting base.
• Range: 0–100% (cannot exceed 100%).
• Interpretation: Measures the floor of your revenue base.
• NRR (Net Revenue Retention)
• Focus: Net change including expansion, contraction, and churn.
• Range: Can be above 100% if expansion outweighs losses.
• Interpretation: Measures the ceiling and overall growth of existing accounts.

Intuition:

• GRR tells you how leaky the bucket is.
• NRR tells you whether the bucket is growing or shrinking overall once you include upsell.

A company can have high NRR but poor GRR if it is heavily reliant on expansion from a subset of customers while losing many others.

What Good Looks Like

• 95%+ GRR – Excellent
• Very low churn and contraction.
• Typical of mission-critical enterprise software or deeply embedded workflows.
• 90–95% GRR – Good
• Healthy retention with manageable losses.
• Sustainable, but still room to improve product, onboarding, or customer success.
• 85–90% GRR – Concerning
• Churn and contraction are meaningful headwinds to growth.
• You must invest more in retention or rely heavily on new sales and expansion.
• Below 85% GRR – Problematic
• The business must acquire substantial new or expansion revenue just to stay flat.
• Indicates deeper issues with product-market fit, pricing, or customer experience.
