GRR is revenue retained from existing customers, ignoring expansion — it caps at 100%.
What it is
Gross Revenue Retention measures how much recurring revenue from an existing customer cohort survives over a period, after downgrades and cancellations but before any expansion. Unlike net revenue retention, it gives no credit for upsells, so it can never exceed 100%. It isolates pure retention, showing how leaky the base is on its own.
Why it matters
GRR strips out the masking effect of upsells, so it reveals the underlying stickiness of a product that NRR can hide. A company can post strong NRR while quietly losing many customers, but a high GRR confirms the base itself is durable. Investors often look at GRR and NRR together to separate retention from expansion.
How it's calculated
Take the starting recurring revenue of a cohort, subtract downgrades and churn, then divide by the starting amount; expansion revenue is never added.
How Quintarthai uses it
When a company discloses both GRR and NRR, you can weigh the gap against the financial trend on its company deep-analysis page to judge how much growth depends on upselling.
Cross-border note. GRR is self-defined and non-GAAP in both Canada and the US; confirm the measurement window and currency before comparing a TSX-listed SaaS issuer to a US-listed one.
FAQ
Why can gross revenue retention never exceed 100%?
GRR excludes expansion revenue and only subtracts losses from the starting base. With nothing added, the most a cohort can retain is everything it started with, which is 100%.
Which is more important, GRR or NRR?
They answer different questions and are best used together. GRR shows how well a company holds its base; NRR shows whether that base grows after expansion. A wide gap means growth leans heavily on upsells.
Check your understanding
Why can Gross Revenue Retention never exceed 100%, while Net Revenue Retention can?
GRR gives no credit for upsells and only subtracts downgrades and churn from the starting cohort, so its ceiling is 100% retention of what it began with.
