SaaS Quick Ratio Calculator

Calculate SaaS Quick Ratio by dividing MRR gained (new + expansion) by MRR lost (churn + contraction). A Quick Ratio above 4 indicates healthy, efficient growth. Below 2 means churn consumes most new revenue. At $6,500 gained and $1,500 lost, your Quick Ratio is 4.3. You add $4.30 for every $1 lost.

The SaaS Quick Ratio measures growth efficiency. how much MRR you add for every dollar you lose. A high Quick Ratio means your growth is sustainable. A low one means you are running on a treadmill, spending on acquisition just to backfill churn. This calculator shows your Quick Ratio, net MRR change, growth efficiency percentage, and a plain-English rating of where you stand.

What is Quick Ratio?

The SaaS Quick Ratio was popularized by Mamoon Hamid at Social Capital as a single number that captures growth efficiency. The formula is simple: divide your incoming MRR (new customers plus expansion from existing customers) by your outgoing MRR (churned customers plus contraction from downgrades). The result tells you how many dollars of new revenue you generate for every dollar you lose.

Unlike raw growth rate, which can mask a leaky bucket with aggressive spending, Quick Ratio exposes the underlying efficiency of your growth engine. A company adding $10,000 in new MRR while losing $8,000 has a Quick Ratio of 1.25x. technically growing, but fragile. The same company adding $10,000 while losing only $2,000 has a Quick Ratio of 5.0x. sustainable, compounding growth that accelerates over time.

Growth efficiency percentage is a complementary way to look at the same data. It shows what fraction of your incoming MRR actually sticks after accounting for losses. A growth efficiency of 77% means 77 cents of every dollar you add becomes permanent net growth, while 23 cents leaks to churn and contraction. The higher this number, the more efficiently your go-to-market investment converts into durable revenue.

Quick Ratio benchmarks

In 2026, the industry average SaaS Quick Ratio sits around 1.82x. That means the typical SaaS company adds less than $2 of revenue for every $1 it loses. barely outrunning churn. Top-quartile companies achieve Quick Ratios of 4.0x or higher, which is generally considered the threshold for healthy, sustainable growth. Below 1.0x means the business is actively shrinking.

Quick Ratio benchmarks shift by stage and market. Early-stage companies with small customer bases can have volatile Quick Ratios; a single large churn event can swing the number dramatically. As you scale past $50K MRR, the number stabilizes and becomes a reliable indicator. SMB SaaS companies typically have lower Quick Ratios (1.5-2.5x) because of higher churn, while enterprise SaaS with annual contracts and expansion revenue routinely exceeds 4.0x.

There are only two levers to improve Quick Ratio: increase the numerator (more new and expansion MRR) or decrease the denominator (less churn and contraction). Reducing the denominator is almost always more cost-effective. See our retention vs acquisition cost calculator for the math. Cutting your churn from $1,500/month to $750/month doubles your Quick Ratio, and the cost of preventing churn through dunning and cancel flows is typically 5-7x less than the cost of replacing customers. Track how this impacts net revenue retention to see the compounding effect.

Your next step

If your Quick Ratio is below 4.0x, churn is the bottleneck; not acquisition. SaveMRR attacks the lowest-hanging fruit first: failed payments, which account for 20-40% of all SaaS churn. Then it identifies voluntary churn risk and triggers automated retention workflows. Most founders see their Quick Ratio improve measurably within 30 days.
