Why NRR Is Your Most Powerful Growth Lever

Net Revenue Retention (NRR) isn’t just a metric—it’s your growth engine.

Featured Article

Everyone seems to be obsessing over Net Revenue Retention (NRR). And honestly, I reckon it’s one of those metrics that totally lives up to the hype.

It’s essentially a direct snapshot into how you’re doing when it comes to loyalty, customer success, and your product-market fit. 

NRR is a unicorn wrapped up in a corporate suit. Get past the jargon and you’ve got one of the most powerful analytical tools out there. 

So I wanna get into what NRR actually tells us, and weigh up how powerful this metric really is.

Compounding Growth Engine 

New customer acquisition = constant investment. You can only get out what you put in. NRR, however, compounds organically as your customer base expands. 

Why does it matter? A 120% NRR will double your revenue every 3.8 years – without any new customer acquisitions.

To get there, you gotta start bringing your NRR to the conversation. Think along these lines:

  • Bring expansion planning into every QBR 

  • Replace “feature adoption” chats with questions like “How did we save you $2M last quarter?”

  • Make your expansion targets everyone’s problem (i.e. Start linking NRR stats to bonuses)

In short – put NRR at the center. 

Validation of Product-Market Fit

Retention rates are the ultimate proof point of product-market fit.

Essentially, a high NRR reflects a customer base that’s loving your brand.  

Why does it matter? Because a product that’s working translates to revenue increases over time. 

Bottom line: let your product do the heavy lifting – not your marketing.

  • Expansion should be baked into your product’s DNA

  • Push in-product upsells to that feel like VIP upgrades, not sales pitches

  • Make the switch to usage-based pricing (let’s be real – no one likes paying for shelfware)

Predictable Revenue

Expansion revenue from existing customers gives you a clearer snapshot into the future. Plus, purchases from this group come with higher gross margins than those from new acquisitions.

Why does it matter? It makes you way more attractive to investors. Public market investors now pay 2.3x higher multiples for SaaS companies with 120% NRR versus sub-100% performers according to Morgan Stanley. 

I get that you can’t directly track future revenue. Instead, I like to keep an eye on the kind of data that will expose any red flags:

  • Product usage patterns (Predict churn before it happens) 

  • Changes in CSAT scores (How’s your customer health looking?)

  • Product penetration (Stack yourself up against the market)

Lower Customer Acquisition Costs 

Attracting and selling new is always going to be harder and more expensive. Customer retention initiatives will drive revenue without nearly the same cost commitments for sales and marketing.

Why does it matter? Spend less to grow more. It’s as simple as that.

You want to make sure you’re sniffing out the opportunities, not letting them appear in retrospect.

  • Design your CSMs for the best ROI potential

  • Nail down a super smooth customer onboarding process with integrated expansion hooks  Tie milestones to $$$ outcomes for your customer (We’ll get you 20% efficiency by Day 30 – or we’ll eat our slide deck)

  • Ditch any friction in your expansion (self-service upgrades > legal team standoffs!)

How you’re stacking up matters

If you’re not sure about your current NRR, here’s how to quickly calculate where you’re at.


NRR = (Starting Revenue + Expansions - Contractions - Churn) / Starting Revenue

For example, if you start the year with $10M ARR:

  • Add $3M in expansions

  • Subtract $500K in contractions

  • Lose $500K to churn

  • End with $12M

  • NRR = ($10M + $3M - $500K - $500K) / $10M = 120%

Here are a few components to add to your tracking list:

Gross Revenue Retention (GRR): Percentage of revenue stays before expansions

Expansion Revenue: Additional revenue from existing customers

Contraction Revenue: Reduction in existing customer spend

Churn Revenue: Complete loss of customer revenue

Remember this

There’s a lot of buzzword metrics out there that don’t actually hold water. NRR just isn’t one of them. 

Go forward with this in mind…"A 120% NRR means your existing customers fund 100% of next year's growth - plus 20% bonus runway."

TL;DR: This isn’t theory—it’s your valuation playbook. NRR isn’t a metric, it’s your new growth department. Treat it that way.

P.S. Customer health scores are not the answer, they are a starting point. Here’s why in my LinkedIn post.
