Net Retention vs. Gross Retention

Net retention and gross retention measure two different things, and mixing them up leads to decisions based on incomplete data. Net Revenue Retention (NRR) tells you whether your existing customer base is growing in value. Gross Revenue Retention (GRR) tells you how well you're holding onto what you already have.

Both numbers matter. Neither one alone gives you the full picture.

What is Net Revenue Retention?

Net Revenue Retention (NRR) is the percentage of recurring revenue you keep from existing customers over a period, including revenue gained from expansions and lost from churn and contractions.

The formula for net revenue retention (NRR):

NRR = (MRR + Expansion - Churn and Contractions) / MRR

MRR is your Monthly Recurring Revenue, the baseline from existing customers at the start of a period. Expansion covers upgrades and upsells. Churn covers cancellations and contract losses. Contractions cover downgrades.

An NRR above 100% means your existing customer base is generating more revenue than it was at the start of the period, even after losses. That's a strong signal your product is delivering enough value that customers want more of it.

What is Gross Revenue Retention?

Gross Revenue Retention (GRR) is the percentage of recurring revenue you retain from existing customers, excluding any expansion revenue.

The formula:

GRR = (MRR - Churn and Contractions) / MRR

GRR can never exceed 100%. It measures only your ability to hold onto existing revenue, making it the cleaner signal for customer retention health.

This financial metric answers a direct question: are customers staying? It strips out the flattering effect of upsells and shows you the baseline.

A related and simpler measure is Customer Retention Rate (CRR):

CRR = 1 - (Customers Lost in a Period / Customers at the Start of a Period)

If you start January with 100 customers and lose 3, your CRR is 97%. CRR is easy to calculate, but it doesn't capture the revenue impact of those losses, which is why GRR is more useful for financial decision-making.

Net retention vs. gross retention: key differences

The difference between NRR and GRR comes down to one thing: expansion revenue.

	NRR	GRR
Includes expansion revenue	Yes	No
Can exceed 100%	Yes	No
Measures	Growth from existing customers	Retention of existing revenue
Best for	Assessing overall revenue health	Diagnosing churn problems

NRR can mask a retention problem. If you're losing customers but upselling the ones who stay, NRR may look healthy while GRR quietly signals trouble. That's exactly why you need both.

Why NRR matters

NRR gives you a forward-looking view of revenue health. A high NRR means your existing customers are generating more over time, which reduces pressure on new customer acquisition to drive growth.

For leaders accountable for revenue targets, NRR answers the question: are we growing from within? Loyal customers who upgrade or expand their contracts are a more efficient source of revenue than net-new acquisition. NRR quantifies that efficiency.

Most SaaS companies treat NRR above 100% as the threshold for healthy growth. It means your existing customer base alone could sustain and grow the business, even without new sales.

Why GRR matters

GRR is your early warning system. It shows whether customers are staying before expansion revenue enters the picture.

A company signing hundreds of new customers while quietly losing existing ones may look fine on an NRR basis for a while. GRR will show the problem sooner. If GRR is declining, something is wrong with retention: the product, the onboarding, the support, or the value customers are getting day to day.

Bigger customers tend to have lower churn rates, which is why GRR often varies by segment. Tracking GRR by customer tier gives you a clearer read on where retention is breaking down.

Why you need both metrics

NRR and GRR answer different questions. Relying on one while ignoring the other creates blind spots that show up in revenue before you have time to act.

The risk of watching only NRR

Strong NRR can hide a churn problem. If expansion revenue from a handful of large accounts offsets losses from smaller ones, your NRR looks healthy while your customer base quietly shrinks. By the time NRR reflects the problem, you may have already lost the customers you needed to retain.

Overweighting NRR also pulls attention toward acquiring and upselling at the expense of serving existing customers. That trade-off tends to accelerate churn, which eventually drags down both metrics.

A poor customer experience among lower-tier customers is often the first casualty of an NRR-only focus. Those customers cancel, GRR drops, and the damage compounds.

The risk of watching only GRR

GRR tells you whether customers are staying, but not whether the relationship is growing. A business with a GRR of 95% but an NRR of 85% is retaining customers but losing revenue within those accounts, a sign that customers are downgrading or finding less value over time.

Focusing only on GRR can also lead to underinvestment in expansion. Even highly retained customers eventually churn for reasons outside your control: budget cuts, team changes, company closures. New revenue from upsells and expansions provides a buffer against that natural attrition.

Industry benchmarks

Benchmarks vary by company size and whether a company is public or private. The figures below apply to SaaS companies, where recurring revenue makes NRR and GRR most relevant.

Public vs. private companies:

• Public companies: median NRR of 114%, median GRR of 90%
• Private companies: median NRR of 104%, median GRR of 89%

By company size (ARR):

• Up to $25M: median NRR of 148%, median GRR of 90%
• $25M to $50M: median NRR of 95%, median GRR of 90%
• $50M to $100M: median NRR of 60%, median GRR of 88%

A healthy NRR target is above 100%. For GRR, 90% or above is a reasonable floor for most SaaS businesses. GRR cannot exceed 100% by definition.

How to improve NRR

If your NRR is below 100%, or you want to push it higher, these approaches tend to move the number:

• Convert free users to paid plans. Freemium users represent unrealized revenue. Time-limited discounts or in-app prompts that highlight premium features can accelerate that conversion.
• Use in-app friction strategically. Gating advanced features or limiting usage creates a natural prompt for upgrades without requiring a sales conversation.
• Invest in product usage data. Analyzing user data tells you which features drive expansion and which ones create friction. Build toward what users value most.

How to improve GRR

GRR improvement is fundamentally about reducing churn. If your GRR is below 90%, focus here first:

• Fix onboarding. Customers who don't reach value quickly are the most likely to cancel. A guided onboarding process that gets users to their first win reduces early churn significantly.
• Prioritize customer support. Exceptional customer service is one of the highest-leverage retention investments a growing company can make. Self-service support options reduce wait times and resolve minor issues before they become cancellation reasons.
• Track behaviour by customer segment. Knowing which pages customers abandon, where friction occurs, and how usage patterns differ by tier tells you where to intervene before churn happens.

Tracking NRR and GRR in a dashboard

Calculating these metrics manually is straightforward. Keeping them current, consistent, and visible to the right people is where most teams run into trouble.

A Klips dashboard connects directly to your billing and subscription data, calculates NRR and GRR automatically, and keeps the numbers updated on a schedule you set. No spreadsheet to maintain. No waiting for someone to pull the numbers. Your team sees the same figures, in real time, without having to ask.

When NRR and GRR are always visible, the conversation shifts from "what are the numbers?" to "what do we do about them?" That's where the real decisions happen.
