Gross Revenue Retention Rate
What This Means:

GRR = ((Starting Revenue - Churned Revenue - Contraction Revenue) / Starting Revenue) × 100

Understanding GRR:

  • 100% GRR: Perfect retention - no revenue lost
  • 90-100% GRR: Excellent retention
  • 80-90% GRR: Good retention
  • Below 80% GRR: May indicate retention challenges

Note: GRR excludes expansion revenue and cannot exceed 100%. It measures your ability to retain existing revenue.
