Gross Revenue Retention
CRM & RetentionAlso: GRR · Gross Retention Rate
Quick definition
Gross Revenue Retention (GRR) measures the percentage of recurring revenue a business retains from existing customers over a period, counting only churn and downgrades. It ignores expansion revenue entirely, which makes it the cleanest read on how sticky a customer base actually is.
Businesses with long contracts and high switching costs tend to sit well above transactional subscription categories. Compare your trend over time more than any single benchmark figure.
How it varies across Australia
GRR varies by contract length and switching cost more than by industry alone. Australian subscription businesses with longer contracts and higher switching friction tend to hold GRR well above transactional software categories where customers churn easily month to month.

Gross Revenue Retention answers one question honestly: if you closed the sales team today, how much of your current recurring revenue would still be here in twelve months? It only subtracts. Churned customers come out. Downgrades come out. Nothing gets added back, not even the customer who doubled their plan last quarter.
That's what separates GRR from its more flattering cousin, Net Revenue Retention (NRR). NRR adds expansion revenue back into the number, which means a business can post NRR above the full starting base even while losing customers, as long as the survivors spend more. GRR can't do that. Its ceiling is the starting base. Nothing higher is mathematically possible.
This makes GRR the number investors and sharp operators check first. A business with strong monthly recurring revenue (MRR) growth and weak GRR is growing on top of a leaky base. It's plugging holes with new customer acquisition cost (CAC) spend instead of fixing the retention rate problem underneath. Churn rate and GRR measure the same leak from two different angles, churn rate as a count of customers lost, GRR as a share of revenue lost.
A net promoter score (NPS) survey might tell you customers are happy. GRR tells you whether they're still paying.
GRR is the only retention number that can't be flattered by a good sales month. It only ever tells you what you kept, never what you added.
How to calculate it
GRR = (Starting MRR minus churned MRR minus downgraded MRR) divided by Starting MRR, expressed as a percentage
Worked example. Start of the month, recurring revenue is $100,000. During the month, $4,000 churns out entirely and $2,000 downgrades to cheaper plans. GRR = ($100,000 minus $4,000 minus $2,000) divided by $100,000 = 94%. Note expansion revenue from upsells is not added back in, even if it happened in the same period.
The Australian context
Australian software-as-a-service (SaaS) businesses selling into small business tend to run lower GRR than those selling into enterprise, mostly because small business customers churn faster during cash-flow pressure and have shorter contract terms. Annual contracts with built-in renewal friction are one of the more reliable levers Australian subscription businesses use to lift GRR without touching the product at all.

Common questions
What's a good GRR benchmark?
Strong subscription businesses tend to hold GRR well above the mid-eighties, with the strongest enterprise software approaching the high nineties. The right target depends on contract length and how easily customers can switch away from your product.
Why does GRR matter more than customer count churn?
Customer count treats a small account and your biggest account as equal losses. GRR is revenue-weighted, so it reflects the actual financial impact of who left, which is what investors and finance teams actually care about.
Can GRR ever be above the starting revenue base?
No. By definition GRR only subtracts churn and downgrades from the starting revenue. It can equal the starting base if nothing was lost, but it can never exceed it. That's the entire point of the metric.
Should downgrades count the same as full churn?
They're both losses and both belong in the calculation, but track them separately too. A downgrade often signals a fixable pricing or product-fit issue, while full churn usually means the relationship is over.
