1. What is Net Retention Rate?

Net Retention Rate (NRR) is a key metric that measures a company's ability to retain and grow revenue from its existing customer base. It accounts for expansion revenue, churned revenue, and downgrades to provide a comprehensive view of customer retention effectiveness.

2. How Does the Calculator Work?

The calculator uses the Net Retention Rate formula:

Where:

• \( SR \) — Starting Revenue ($)
• \( ER \) — Expansion Revenue ($)
• \( CR \) — Churned Revenue ($)

Explanation: The formula calculates what percentage of starting revenue is retained after accounting for both revenue expansion and customer churn. A value above 100% indicates net revenue expansion from the existing customer base.

3. Importance of NRR Calculation

Details: NRR is crucial for SaaS and subscription-based businesses to measure customer success, product value, and overall business health. A high NRR indicates strong customer retention and growth potential, while a low NRR may signal issues with customer satisfaction or product-market fit.

4. Using the Calculator

Tips: Enter all values in dollars. Starting revenue must be greater than zero. Expansion revenue includes upsells and cross-sells. Churned revenue includes downgrades and cancellations.

5. Frequently Asked Questions (FAQ)

Q1: What is a good Net Retention Rate?
A: For SaaS companies, NRR above 100% is generally good, with excellent companies achieving 120%+. Below 100% indicates revenue contraction from existing customers.

Q2: How does NRR differ from Gross Retention Rate?
A: Gross Retention Rate only measures revenue retention without expansion (GRR = (SR - CR)/SR × 100), while NRR includes expansion revenue.

Q3: What time period should be used for NRR calculation?
A: Typically calculated monthly or annually. The time period should be consistent for comparative analysis.

Q4: Can NRR be negative?
A: Technically yes, if churned revenue exceeds the sum of starting and expansion revenue, but this indicates severe business challenges.

Q5: How often should NRR be monitored?
A: Monthly tracking is recommended for most businesses to quickly identify trends and take corrective actions when needed.
