What is Quick Ratio?

Why It Matters

Quick Ratio exposes what a raw MRR growth number hides, whether growth is coming from genuinely strong momentum or is being propped up by aggressive new sales while the back door quietly leaks revenue. A business can show healthy month-over-month MRR growth and still be sitting on a fragile quick ratio if churn is climbing at the same pace. Watching this ratio over time catches that kind of deterioration early, often before it shows up in the headline growth rate. It also helps leadership decide where to focus, a low ratio points toward a retention problem worth fixing, while a high one confirms that growth investment is compounding rather than just replacing losses. Investors and boards frequently ask for this number specifically because it's harder to game than top-line MRR growth alone.

Example

A company adds $60,000 in new MRR and $20,000 in expansion MRR in a month, while losing $15,000 to churn and $5,000 to downgrades. Quick Ratio is $60,000 plus $20,000, divided by $15,000 plus $5,000, which equals 4. That means the business is growing recurring revenue four times faster than it is losing it. If that ratio falls to 1.5 the following month even though new MRR stayed flat, the drop points to a growing churn or contraction problem eating into growth that a single MRR growth-rate number would not reveal on its own.

Frequently Asked Questions

• What counts as revenue gained and lost in Quick Ratio?

  Gained revenue is new MRR from new customers plus expansion MRR from upgrades. Lost revenue is churned MRR from canceled accounts plus contraction MRR from downgrades.

• How is Quick Ratio different from net revenue retention?

  Net revenue retention tracks existing customers only, excluding new business. Quick Ratio includes new MRR in the gains side, making it a broader read on overall growth efficiency, not just retention of the existing base.

• What is a good Quick Ratio for a SaaS company?

  A ratio above 4 is generally considered strong and sustainable, a ratio between 1 and 4 suggests growth is happening but fragile, and a ratio at or below 1 means losses are roughly canceling out gains.

• How often should Quick Ratio be measured?

  Most SaaS companies calculate it monthly alongside their other MRR metrics, since it's built from the same new, expansion, churned, and contraction MRR figures already tracked each month.

• What causes Quick Ratio to fall?

  A falling ratio usually means churned or contraction MRR is rising faster than new and expansion MRR, even if new MRR itself looks stable or is still growing.
