What is SaaS quick ratio? Definition, Formula & Benchmarks

What is saas quick ratio?

The SaaS quick ratio measures growth efficiency by comparing the recurring revenue you gain to the recurring revenue you lose. It divides new plus expansion MRR by churned plus contraction MRR. A ratio above 1 means you're growing net revenue; below 1 means losses are outrunning gains.

Formula

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

New MRRMonthly recurring revenue from newly acquired customers
Expansion MRRAdded recurring revenue from existing customers upgrading or adding seats
Churned MRRRecurring revenue lost from customers who fully cancelled
Contraction MRRRecurring revenue lost from existing customers downgrading

Worked example

Add $50,000 new and $20,000 expansion MRR against $10,000 churned and $5,000 contraction, and your quick ratio is 4.7 ($70,000 ÷ $15,000).

Why it matters for fast-growing companies

The quick ratio tells you how much of your hard-won new revenue is being eaten by losses out the back door. A ratio near 1 means you're running on a treadmill. Higher numbers show efficient, durable growth, so treat a falling quick ratio as a signal to fix retention before pouring more into acquisition.

Frequently asked questions

What counts as a healthy SaaS quick ratio?+

Any ratio above 1 means you're net-growing recurring revenue, and higher is better because it shows gains comfortably outpace losses. A ratio near 1 signals you're barely staying even. Rather than chase a single target number, watch the trend and the components. Rising churn will drag the ratio down even if new sales look strong.

Why use the quick ratio instead of just growth rate?+

Raw growth rate hides how you got there. The quick ratio separates the gains (new and expansion) from the losses (churn and contraction), so two companies growing at the same rate can look very different. It surfaces whether your growth is efficient or is masking a serious retention leak.
