What Is Net Revenue Retention (NRR)?

Net Revenue Retention (NRR) is a measure of how much recurring revenue a business retains from existing customers over a given period. It factors in:

• Starting ARR (Annual Recurring Revenue)
• Expansion Revenue (upsells, cross-sells, and add-ons)
• Churned Revenue (customers who leave)
• Downgrade/Contraction Revenue (customers who downgrade to lower plans)

A higher NRR means your company is successfully retaining and expanding customer accounts, while a lower NRR indicates possible churn or retention issues.

How the NRR Calculator Works

The calculator simplifies the process by automatically applying this formula:

NRR = (Ending ARR ÷ Starting ARR) × 100

Where:

• Ending ARR = Starting ARR + Expansion – Churn – Downgrade

The result is shown as a percentage, along with the net revenue change and ending ARR.

Practical Example

Let’s walk through a real calculation using the tool:

• Starting ARR: $100,000
• Expansion Revenue: $15,000
• Churned Revenue: $8,000
• Downgrade Revenue: $3,000

Step 1 – Net Revenue Change
$15,000 – $8,000 – $3,000 = $4,000

Step 2 – Ending ARR
$100,000 + $4,000 = $104,000

Step 3 – Net Revenue Retention Rate
($104,000 ÷ $100,000) × 100 = 104%

👉 This means the business not only retained all revenue but also grew by 4% within the existing customer base.
