Gross Retention vs. Net Retention
Gross Revenue Retention and Net Revenue Retention measure similar things but tell very different stories. Here is how to read each one, and when to trust which number.
Gross vs. Net Revenue Retention
Retention is one of the clearest signals of business health, especially if you run a subscription-based model. Two metrics dominate this conversation: Gross Revenue Retention and Net Revenue Retention. They measure similar things but tell very different stories.
Knowing which number to trust, and when, is the difference between a confident decision and a misleading one.
What is revenue retention?
Revenue retention measures how well a business holds onto the revenue it already earns from existing customers over a given period. It is a vital financial metric for any business built on recurring revenue.
A high retention rate signals a loyal customer base. A declining one tells you something is wrong before it shows up in your total revenue figure.
Both Gross Revenue Retention and Net Revenue Retention are revenue retention metrics. Understanding each one gives you a clearer picture of where your revenue is stable, where it is growing, and where it is quietly slipping.
What is Gross Revenue Retention?
Gross Revenue Retention (GRR) is the percentage of recurring revenue retained from existing customers over a period, excluding any expansion revenue from upgrades or upsells.
Gross Revenue Retention focuses only on what you kept. It does not count new customers, and it does not count revenue gained from customers spending more. It is a clean read on your core retention performance.
GRR can never exceed 100%. If it is declining, customers are churning or downgrading, and no amount of upsell activity will hide that in this number.
Calculating Gross Revenue Retention Rate
GRR is straightforward to calculate. You need two numbers: the recurring revenue you started with and the revenue lost to churn or downgrades.
The formula:
Gross Retention Rate = (Starting MRR - Churned MRR - Downgrade MRR) / Starting MRR × 100
Example: A business starts the month with $100,000 in recurring revenue. By month end, $10,000 has churned (customers who cancelled).
GRR = ($100,000 - $10,000) / $100,000 × 100 = 90%
A 90% GRR means the business retained 90 cents of every dollar it started with, before accounting for any expansion.
What is Net Revenue Retention?
Net Revenue Retention (NRR) is the percentage of recurring revenue retained from existing customers over a period, including the impact of upgrades, upsells, and downgrades.
Where GRR shows you what you kept, NRR shows you what you kept and grew. A business with strong NRR is not just holding its customer base, it is expanding revenue from within it. NRR can exceed 100%, which means existing customers are spending more than they were at the start of the period.
This is the number that tells you whether your product is becoming more valuable to customers over time, or less.
Calculating Net Revenue Retention Rate
NRR adds expansion revenue (upgrades, upsells) and subtracts revenue lost to downgrades and churn.
The formula:
Net Retention Rate = (Starting MRR + Expansion MRR - Churned MRR - Downgrade MRR) / Starting MRR × 100
Example: A business starts the month with $100,000 in recurring revenue. During the month: $5,000 in upgrades, $10,000 churned, $5,000 lost to downgrades.
NRR = ($100,000 + $5,000 - $10,000 - $5,000) / $100,000 × 100 = 90%
In this case, NRR and GRR land at the same number because expansion and downgrades cancel out. In practice, a healthy SaaS business often sees NRR above 100% when expansion revenue outpaces churn.
Gross Retention vs. Net Retention: key differences
GRR and NRR answer different questions. Use the right one for the question you are actually asking.
| Gross Revenue Retention (GRR) | Net Revenue Retention (NRR) | |
|---|---|---|
| What it measures | Revenue kept from existing customers, after churn and downgrades | Revenue kept and grown from existing customers, including expansion |
| Includes upgrades/upsells | No | Yes |
| Can exceed 100% | No | Yes |
| Best for | Measuring core retention health | Measuring overall revenue growth from existing customers |
| Hides expansion revenue | Yes | No |
GRR gives you a conservative, honest read on churn. NRR gives you the full picture of what your existing customer base is worth over time.
A business with low GRR but high NRR is papering over a churn problem with upsell activity. That is a warning sign, not a success story. Both numbers together tell you the truth.

The right metric depends on what you need to know.
For SaaS and subscription businesses
If your product has multiple tiers, add-ons, or usage-based pricing, customers move up and down frequently. NRR is the more meaningful number because it reflects the full revenue impact of those movements.
A SaaS business targeting NRR above 100% is in a strong position: existing customers are funding growth without relying entirely on new acquisition.
For business leaders and operators
Track both. GRR tells you whether your core product is retaining customers. NRR tells you whether your broader offering is growing revenue from those same customers. A gap between the two is worth investigating.
If you are presenting retention to investors or a board, NRR is the headline number. If you are diagnosing a churn problem internally, GRR is where to start.
For marketers
GRR reflects how well your core product delivers on its promise. NRR reflects how well your additional offerings resonate. Both metrics point to where marketing energy is worth spending, whether that is reducing churn through better onboarding or driving expansion through targeted campaigns.
Improving your retention numbers
After reviewing your GRR and NRR, a few strategies consistently move both numbers in the right direction.
Customer segmentation and lifetime value: Identify which customers are most valuable and most at risk. Segment them, then direct your retention efforts where they will have the most impact. Grouping customers also lets you test different approaches and measure what works.
Upsell and cross-sell with purpose: Expansion revenue improves NRR, but only if the upgrade is genuinely right for the customer. Upsells done with the customer's outcome in mind build loyalty. Upsells done purely for revenue accelerate churn.
Proactive outreach to at-risk accounts: Do not wait for customers to cancel. Automated campaigns that flag disengagement early give your team a chance to intervene before the decision is made.
Data-driven product improvements: Customer surveys and usage data reveal why customers churn or downgrade. Acting on that signal improves retention more reliably than any single campaign. When the numbers are always visible, you spend less time figuring out what happened and more time deciding what to do next.
Tracking GRR and NRR on a live dashboard means you stop waiting for a monthly report to know whether retention is improving. You know, and you can act.
FAQ
Gross Retention vs. Net Retention: which number matters most?
Both. GRR tells you whether your product earns its keep. NRR tells you whether your customer relationships are growing in value. A business that tracks only one is missing half the story.
The clearest signal of a healthy retention model: GRR is stable or rising, and NRR is above 100%. That means you are keeping customers and they are spending more over time. No new acquisition required to grow.
Keeping both numbers visible, consistently and in real time, means you spend less time pulling reports and more time acting on what they reveal.
