Understanding SaaS Quick Ratio

How we calculate. Quick ratio = growth MRR ÷ lost MRR. See our methodology and accuracy policy .

Real-world scenario: A typical SaaS Quick Ratio case uses new mrr 40000 and expansion mrr 20000. Enter the same figures below to reproduce the worked path.

What is SaaS Quick Ratio?

A SaaS growth-efficiency KPI (also called SaaS quick ratio). Distinct from accounting acid-test quick ratio and from NRR.

  • Growth MRR = new + expansion
  • Lost MRR = churned + contraction
  • Same period

The Formula

SaaS Quick Ratio
Quick ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR)

Worked Example

Scenario: New $40,000; expansion $20,000; churned $10,000; contraction $5,000.
Step 1: Growth = 40000 + 20000 = 60000
Step 2: Lost = 10000 + 5000 = 15000
Step 3: 60000 ÷ 15000 = 4
Answer: Quick ratio is 4.0×.
