Free CX Metrics Calculator: NRR, GRR, CLV, and LTV:CAC

Quick Answer

Net Revenue Retention (NRR) measures revenue growth from existing customers. Formula: (Starting ARR + Expansion - Contraction - Churn) / Starting ARR

Elite SaaS companies hit 130%+ NRR. Best-in-class is 120%+. If you're below 100%, you're losing ground. These calculators help you run the numbers in 30 seconds. No signup required.

The Four Metrics That Actually Matter

Most CX leaders get asked about NRR in board meetings and have to say "let me get back to you on that." Or they know the number but can't explain what's driving it. Sales knows their pipeline coverage. The CFO knows burn rate and runway. Product knows velocity and deployment frequency. CX leaders should know their retention and expansion metrics just as cold. These four metrics are the baseline:

NRR
Are you growing from existing customers?
GRR
What's your baseline retention before expansion?
CLV
How much is a customer worth over their lifetime?
LTV:CAC
Are your unit economics healthy?

If you can't answer these questions in a board meeting, you're at a disadvantage. Let's fix that.

Net Revenue Retention (NRR) Calculator

NRR shows whether you're growing revenue from existing customers without relying on new sales.

Your NRR
110.0%
Stable

What good looks like:

  • 130%+ = Elite tier (top SaaS companies)
  • 120-129% = Best-in-class
  • 110-119% = Good
  • 100-109% = Stable but not growing much
  • Below 100% = Shrinking

"If you're below 110%, you need to figure out if it's a retention problem or an expansion problem. Run GRR next to diagnose."

Gross Revenue Retention (GRR) Calculator

GRR shows how much of your existing revenue you're keeping, before any expansion.

Your GRR
90.0%

What this tells you:

Strong GRR but weak NRR:

You're retaining customers but not growing them. Focus on expansion strategies and cross-sell playbooks.

Weak GRR:

You have a fundamental retention problem. Expansion won't save you if the bucket is leaking.

Customer Lifetime Value (CLV) Calculator

CLV is the total profit you expect from a customer over their entire relationship with you.

Lifetime Value (LTV)
$500,000
LTV:CAC Ratio
33.3x

LTV:CAC Benchmarks:

  • 5x+ = Excellent
  • 3-5x = Healthy
  • 2-3x = Acceptable
  • Below 2x = Unit economics don't work

"A 2-point improvement in churn rate can double your LTV. Run the numbers to see the impact."

Churn Impact Calculator

This shows you the revenue value of reducing churn. Use it to justify retention investments.

Annual Revenue Saved

By hitting your 10% churn target

"Reducing churn from 12% to 10% saves us $240K over 12 months. That's 4.8x the cost of a new CSM hire. Executives approve investments when you can show the math."

Why These Four Metrics?

You could track dozens of metrics. CSAT, NPS, health scores, support tickets, time-to-value, feature adoption... But when a board member or your CEO asks "how's CS doing?", they want to know three things:

  • Are we keeping customers? (GRR)
  • Are we growing them? (NRR)
  • Do the economics work? (LTV:CAC)

Everything else is a leading indicator or a vanity metric. These four are the outcomes that matter.

Stop Guessing. Start Modeling.

CadenceCX tracks all four metrics with saved scenarios, historical trends, and executive summaries you can share in Slack or email.

The Bottom Line

You should be able to say your NRR and GRR as easily as you say your name. If you can't, you're guessing when executives ask hard questions. These calculators take 30 seconds. The clarity they provide lasts all quarter. Run the numbers. Know where you stand. Make better decisions.
