SaaS Gross Revenue Retention (GRR)

0.00%
Gross Revenue Retention (GRR) measures the percentage of recurring revenue retained from existing customers, excluding expansion revenue. It considers both revenue churn and contraction.

How to Calculate SaaS Gross Revenue Retention (GRR)

Follow these steps to compute your SaaS gross revenue retention (GRR) rate: 

  1. Identify your Beginning Period ARR. This is your Annual Recurring Revenue at the start of the period you are measuring, such as the beginning of the year or quarter. Example: A small SaaS company might start with $500,000 ARR, while a larger one may begin with $5,000,000.
  2. Determine your Contraction ARR. This includes revenue lost from existing customers who downgrade or reduce usage during the period. Example: A contraction of $20,000 might occur if customers move to cheaper plans or reduce seats.
  3. Calculate your Churn ARR. This represents revenue lost from customers who cancel their subscriptions. Example: A small business might lose $30,000, while a larger one could lose $300,000.
  4. Calculate the Retained Revenue by subtracting the Contraction ARR and Churn ARR from the Beginning Period ARR. Example: For a small company, $500,000 – $20,000 – $30,000 = $450,000, and for a larger one, $5,000,000 – $100,000 – $300,000 = $4,600,000.
  5. Divide the Retained Revenue (from Step 4) by the Beginning Period ARR (from Step 1) to find the GRR. Example: For the smaller company, $450,000 / $500,000 = 0.90 or 90%, and for the larger, $4,600,000 / $5,000,000 = 0.92 or 92%.

Note: Ensure all data points (Beginning ARR, Contraction, and Churn) are for the same time period. GRR exclusively measures the retention of existing revenue, not including new revenue.

SaaS Gross Revenue Retention (GRR) = ((Beginning Period ARR – Contraction ARR – Churn ARR)/Beginning Period ARR).

Understanding SaaS Gross Revenue Retention (GRR)

What is Gross Revenue Retention?

Imagine a company as a bucket, with revenue being the water inside it. Gross Revenue Retention (GRR) acts like an inspector checking if the bucket is strong enough to hold the water it already has, without considering any new water added. This examination focuses solely on the water (revenue) that was in the bucket at the start, looking for any leaks such as lost customers or reductions in spending.

Gross Revenue Retention is technically defined as the ratio of the recurring revenue at the end of a period to the total recurring revenue at the beginning of that period, subtracting any losses from downgrades and customer churn. A high GRR signals that the company maintains a stable base of existing revenue, highlighting its ability to retain customers and sustain income without relying on new sales.

  • Sustain revenue by highlighting retained recurring revenue from existing customers.

  • Guide strategy by providing insights into customer success, pricing, and product satisfaction.

  • Benchmark performance to identify areas for customer retention improvement.

Practical Examples of SaaS Gross Revenue Retention (GRR)

  • Example 1: In one experience, the shift to a subscription-based model in a SaaS company led to an increase in Gross Revenue Retention (GRR) from $100,000 to $150,000 monthly. The change was directly related to more consistent monthly revenues driven by the predictability of subscription payments.
  • Example 2: By extending subscription periods, a company noticed a rise in GRR, which went up by 20%. Previous annual subscriptions of $200,000 grew to $240,000 annual revenue post-extension, reflecting customer satisfaction with the lengthier commitment terms.
  • Example 3: A company implemented an upgrade path for existing customers, resulting in a GRR increase from 75% to 85%. Customers opting for higher-tiered services at an average price increase from $50 to $75 directly influenced this growth.
Period Starting MRR Lost MRR Downgraded MRR Ending MRR GRR GRR Change
Month 1 $500,000 $10,000 $5,000 $485,000 97% –
Month 2 $485,000 $12,000 $3,000 $470,000 96.9% -0.1%
Month 3 $470,000 $8,000 $2,000 $460,000 97.9% +1.0%

Trend Analysis: In this example, the Gross Revenue Retention (GRR) rate shows a slight decrease between Month 1 and Month 2, from 97% to 96.9%, indicating a higher loss in revenue. However, it recovers in Month 3 to 97.9%, showing an improvement in retaining revenue. This trend indicates that, while some initial revenue losses were experienced, the business is becoming better at retaining revenue over time.

GRR = ($470,000 – $8,000 – $2,000) / $470,000 = 97.9%

Different Ways to Calculate SaaS Gross Revenue Retention (GRR)

  • Simple GRR: Measures revenue at the end of a period compared to the beginning, adjusted for churn and downgrades, giving an overview of revenue retention capabilities.
  • Cohort-based GRR: Tracks revenue from customers signed up in the same period, using cohorts to analyze customer behavior over time.
  • Weighted GRR: Emphasizes the importance of retaining high-value customers by considering their revenue impact more heavily.

How to Improve Your SaaS Gross Revenue Retention
