Gross and net revenue retention sound like the same idea measured two ways. They are not. One tells you whether you are keeping what you have. The other can hide the answer. Here is what each number means, how to calculate them, what good looks like and which one your board should really be asking for. Written to be useful whether this is new to you or not.


Most SaaS teams track net revenue retention because it is the number investors ask about. Fewer track gross revenue retention with the same care. That is a problem, because gross retention is often the more honest of the two. The numbers look almost identical on a slide. They can tell opposite stories about the health of your business.


This is a plain-English guide to both. If you are new to the field, you will get clear definitions, the formulas and a worked example. If you have been doing this for years, the part worth your time is the gap between the two numbers and what it reveals. Either way, you will leave with something you can act on.


The two numbers, in plain terms


Both numbers start from the same place: the recurring revenue you had from a group of customers at the start of a period, usually a year. Then they measure what happened to that revenue.


Gross revenue retention (GRR) asks one question. Of the revenue you started with, how much did you keep. It subtracts the revenue you lost to customers leaving (churn) and to customers downgrading (contraction). It does not count any revenue you gained from existing customers buying more. Because of that, GRR can never go above 100%. The best possible score is keeping every penny you started with.


Net revenue retention (NRR) asks a broader question. Starting from that same base, where did the revenue end up. It subtracts the same churn and contraction, then adds back the expansion revenue you earned from existing customers through upsells, cross-sells and price increases. Because expansion is included, NRR can go above 100%. A company can lose some customers and still post NRR well over 100% if the customers who stayed spent enough more to cover it.


In one line each:


GRR measures what you kept. NRR measures what you kept plus what you grew.


The formulas, if you want them:


GRR = (starting revenue minus churn minus contraction) divided by starting revenue.


NRR = (starting revenue minus churn minus contraction plus expansion) divided by starting revenue.


A worked example


Numbers make this concrete. These are illustrative round figures, not real data.


Imagine you start the year with 1,000,000 in annual recurring revenue from your existing customers. Over the year you lose 100,000 to customers who cancel, you lose another 50,000 to customers who downgrade and you gain 200,000 from existing customers who expand.


Your gross retention ignores the expansion. You kept 1,000,000 minus 150,000, which is 850,000 of your starting revenue. That is a GRR of 85%.


Your net retention adds the expansion back. You ended at 1,000,000 minus 150,000 plus 200,000, which is 1,050,000. That is an NRR of 105%.


Same company, same year. One number says you lost 15% of your base. The other says you grew 5%. Both are true. They are answering different questions.


Now the insight that matters. Picture a second company that also posts 105% NRR but got there differently. It lost only 20,000 to churn and contraction, then expanded by 70,000. Its NRR is 105% as well, but its GRR is 98%. Two companies, identical headline NRR, completely different businesses underneath. The first is refilling a leaky bucket. The second is barely leaking at all. NRR alone cannot tell them apart. GRR can.


Why GRR is the honest floor


Here is why gross retention deserves more attention than it usually gets. Expansion can flatter a business for a long time. A handful of large customers growing fast can push NRR above 100% even while the wider base is quietly churning. Gross retention strips all of that away. It cannot be inflated by a good expansion quarter and it cannot hide a churn problem behind a few big wins. It answers the one question that sits underneath everything else: is the core of what we sell holding.


That is also why GRR is the better early warning. Expansion is the last thing to go and the first thing to be talked up. Churn and contraction, which is all GRR measures, is where the truth about product value and customer experience shows up first.


What good looks like


Benchmarks help, as long as you use the right ones. Two figures worth knowing, both from publishers who run annual private SaaS surveys.


SaaS Capital treats a gross retention rate of at least 90% as table stakes for B2B SaaS. In other words, keeping 90% or more of your starting revenue, before any expansion, is the level a healthy company is expected to clear.


Benchmarkit's 2025 research put the median gross retention lower and noted it has drifted from 90% to 88% over three years, which it flags as a warning sign while also cautioning that some of the movement could come from which companies chose to take part.


One caveat matters more than the exact numbers. Retention varies enormously by how much you charge. Both surveys find that gross retention rises as average contract value rises, because higher-priced products tend to involve deeper implementation, dedicated support and stickier commitments. A company selling low-priced, high-volume subscriptions will have structurally lower gross retention than one selling six-figure enterprise contracts. That is the shape of the business rather than a failure of its team. So benchmark against companies at your price point, not against a blended median. We went deep on why that matters in our guide to net revenue retention benchmarks. The same logic applies to gross retention.


The number your board should actually ask for


If you take one thing from this, take this. The most revealing retention metric is not GRR or NRR on its own. It is the gap between them.


A small gap means your net number is built on a solid base. You are keeping most of what you have and expansion is adding on top of a stable foundation. A wide gap means the opposite. Your healthy-looking NRR is being held up by expansion that is masking real churn underneath. That is a leaky bucket being refilled by a few growing accounts and it carries a risk the blended number hides completely: concentration. If one or two of those expanding accounts leave, the mask comes off all at once.


So the sharper question for any board or investor update is not "is our NRR good". It is three questions in order. What is our gross retention, benchmarked against peers at our price point. How wide is the gap between our gross and net retention. And is that gap spread across the base or riding on a small number of accounts we cannot afford to lose.


How to improve each number


Knowing the numbers is only useful if you can move them. The order matters here, so start with gross.


To lift gross retention, you are fighting churn and contraction and almost all of that work happens long before the renewal. Get customers to value quickly through strong onboarding. Drive adoption across a team rather than a single user, because a product used by one person is one resignation away from churn. Catch risk early using the qualitative signals that usage dashboards miss. Handle incidents and outages in a way that protects trust rather than eroding it. And close the back door of involuntary churn, the revenue you lose silently to failed payments and expired cards, which is pure leakage you can often recover with better billing follow-up.


To lift net retention beyond that floor, you add earned expansion. Widen your relationships beyond a single champion. Surface upsells and cross-sells where the customer has genuinely realised value, not as a quota-driven reach. Expansion built on real outcomes compounds. Expansion pushed on customers who are not ready shows up later as contraction or churn.


The sequencing is the actionable heart of it. You cannot out-expand a leaky bucket. Chasing NRR while your GRR is weak just means selling more into a base that keeps draining. Fix the floor first, then build on it.


Frequently asked questions


What is the difference between gross and net revenue retention?

Gross revenue retention measures how much of your starting recurring revenue you kept, counting only churn and contraction, so it can never exceed 100%. Net revenue retention starts from the same base but adds expansion revenue back in, so it can exceed 100%. GRR shows what you kept. NRR shows what you kept plus what you grew.


What is a good gross revenue retention rate?

For B2B SaaS a common benchmark is at least 90%, which SaaS Capital treats as table stakes, though it varies by average contract value, with higher-priced products retaining better. Benchmark against companies at your price point rather than a blended median.


Can gross revenue retention be more than 100%?

No. Gross retention excludes expansion revenue, so the best possible outcome is keeping everything you started with, which is 100%. If a retention number is above 100%, it is net retention, not gross.


Why does the gap between GRR and NRR matter?

The gap shows how much of your net retention depends on expansion. A small gap means a healthy, stable base. A wide gap means expansion is masking real churn underneath, which carries concentration risk if the expanding accounts leave. Two companies with the same NRR can have very different gross retention and the gap is what tells them apart.


How do you calculate gross revenue retention?

Take your recurring revenue from a set of customers at the start of a period, subtract the revenue lost to cancellations and downgrades over that period, then divide by the starting revenue. Do not include any expansion revenue. The result, as a percentage, is your GRR.


If your gross and net retention are telling different stories, the gap is where your growth is quietly leaking. The Customer Success Economic Model turns each point of retention into what it is actually worth to your growth rate and the Board and Investor CS Reporting Pack puts these numbers, properly segmented, in front of the people asking for them. Both sit on the idea at the heart of The Compounding Customer: retention is the compounding engine, not a quarterly scramble.
