Chart: Gross MRR Retention

If you’re new to ChartMogul, get to know how charts work.

Gross MRR Retention (GRR) charts the change in monthly recurring revenue (MRR) retained from subscribers, offset by losses due to contraction and churn.


Gross MRR Retention (GRR) charts the percentage of MRR retained in a given report interval considering losses due to contraction and churn within the interval. It gives you insight into how well you retain revenue (without expansion) from existing subscribers. For SaaS businesses, GRR ideally exceeds 90%.

What insights can I gain from GRR?

Gross MRR Retention, also known as Gross Renewal Rate (GRR), is an indicator of how well you retain subscribers at their current price point or contract value. The lower your GRR, the more your business growth is negatively impacted by contraction and churn.

Chart Notes


ChartMogul calculates GRR as total MRR from existing subscribers at the start of the report interval and subtracts contraction and churn during the interval divided by total MRR from subscribers at the start of the interval:

(Starting MRR − Contraction MRR − Churn MRR) ÷ Starting MRR


At the start of the month, you have $100 in MRR. During the month, you lose $10 to churn and $10 to contraction. Your net GRR retention rate is 80%: ($100 − $10 − $10) ÷ $100.

Chart Data

The Chart Data table for Gross MRR Retention works differently than other charts. It provides the following breakdown:

  • Starting MRR — The value of MRR at the beginning of the report interval.
  • Contraction MRR — The net loss in MRR from existing customers in the report interval.
  • Churn MRR — The net loss of MRR from existing customers who canceled their last (or only) subscription in the report interval.
  • Gross MRR Retention — The percentage value of gross MRR retained in the report interval.
