Quick Ratio (SaaS)

Quick Definition

A growth efficiency metric comparing revenue added (new + expansion) to revenue lost (churn + contraction), showing net growth quality.


What is Quick Ratio?

The SaaS Quick Ratio measures growth efficiency by comparing how much revenue you're adding versus losing. It's calculated as (New MRR + Expansion MRR) divided by (Churned MRR + Contraction MRR).

A Quick Ratio of 4 means you're adding $4 in new revenue for every $1 you lose. The higher the ratio, the more efficient your growth engine.

Why Quick Ratio Matters

Quick Ratio reveals whether you're growing from a position of strength or desperately trying to outrun a leaky bucket. A company adding $100K but losing $80K is in a very different position than one adding $100K and losing $20K.

Investors love this metric because it shows growth quality, not just growth quantity. High Quick Ratio companies can sustain growth even if new customer acquisition slows.

Quick Ratio Benchmarks

Below 1: Shrinking. You're losing more than you're gaining. 1-2: Struggling growth. Too much energy fighting churn. 2-4: Healthy growth. Good balance. Above 4: Excellent. Very efficient growth engine.

Formula

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

Higher is better. Aim for 4+ for healthy growth.

Example

Monthly MRR movements:

  • New MRR: $25,000
  • Expansion MRR: $10,000
  • Churned MRR: $6,000
  • Contraction MRR: $2,000

Quick Ratio = ($25K + $10K) ÷ ($6K + $2K) = $35K ÷ $8K = 4.4

Excellent ratio. You're adding $4.40 for every $1 lost. Growth is healthy and efficient.
