What is SaaS Gross Revenue Retention (GRR)?

The Formula

SaaS Gross Revenue Retention
GRR % = (Start MRR − Contraction − Churned MRR) ÷ Start MRR × 100

Worked Example

Scenario: Start MRR $100,000; contraction $5,000; churned $8,000.
Step 1: 100000 − 5000 − 8000 = 87000
Step 2: 87000 ÷ 100000 = 0.87
Step 3: × 100 = 87%
Answer: 2000% (part ÷ whole × 100; verified with this calculator).
