SaaS Quick Ratio Calculator
Divide the MRR you gained by the MRR you lost to see how efficient your growth really is — whether you are compounding or just outrunning churn. No signup required.
How It Works
1
Enter the MRR you gained
New MRR from brand-new customers plus expansion MRR from upgrades and seat additions — the numerator of the quick ratio.
2
Enter the MRR you lost
Churned MRR from cancellations plus contraction MRR from downgrades — the denominator. Use the same period for all four inputs.
3
See how efficient your growth really is
The calculator divides gains by losses, places you in a benchmark band, tells you which side is driving the number, and calculates the churn ceiling you have to stay under to hold an elite ratio.

How to Calculate the SaaS Quick Ratio
The SaaS Quick Ratio Formula
Quick Ratio = (New MRR + Expansion MRR) ÷ (Churned MRR + Contraction MRR)
A ratio of 4 means you add $4 of recurring revenue for every $1 you lose
The SaaS quick ratio — popularized by Mamoon Hamid and unrelated to the accounting quick ratio that measures liquidity — answers a question net new MRR cannot: how efficiently are you growing? Two companies can both add $10,000 of net new MRR in a month. One adds $12,000 and loses $2,000; the other adds $50,000 and loses $40,000. Identical net growth, completely different businesses. The first has a quick ratio of 6 and compounds. The second has a quick ratio of 1.25 and is running a treadmill that gets steeper with scale.
Both losses belong in the denominator on purpose. Churned MRR is revenue from customers who left entirely; contraction MRR is revenue lost when customers stayed but shrank. Counting only cancellations would flatter any product where accounts quietly downsize. Work out the components first with the MRR Calculator, which breaks a month into new, expansion, contraction, and churned MRR — the exact four inputs this tool needs.
What Is a Good SaaS Quick Ratio?
A ratio of 1.0 is the break-even line: gains exactly offset losses and the business is flat. The bands above and below it say more about durability than the raw number:
4.0+ — Elite
Best-in-class growth efficiency. Nearly every dollar of acquisition spend sticks, so growth compounds instead of being spent replacing lost revenue. This is the band the benchmark was originally written around.
2.0–4.0 — Healthy
Growth clearly outpaces churn. Common and perfectly fundable, especially in SMB SaaS where churn is structurally higher. The question to keep asking is whether the ratio holds as you scale.
1.0–2.0 — Acceptable
You are growing, but churn and contraction absorb most of what you add. Acquisition spend is partly paying to replace revenue you already had. Retention work returns more here than more top-of-funnel.
Under 1.0 — Shrinking
You lose more recurring revenue than you add. New sales cannot fix this — at a ratio below 1 the leak grows with the customer base. Diagnose retention before spending another dollar on growth.
Read the band alongside your stage. Early on, a small base makes the ratio swing wildly — a single lost enterprise account can halve it. It becomes a trustworthy signal once you have enough accounts that no one customer dominates the denominator, and it is most useful tracked as a trend over six to twelve months rather than judged on one month.
Quick Ratio vs NRR vs Churn Rate
These three metrics overlap but answer different questions, and using the wrong one hides problems. Net revenue retention looks only at your existing customer base — expansion minus churn and contraction, with new business excluded — so it measures whether the book of business you already have grows on its own. The quick ratio deliberately includes new business, so it measures the whole growth engine: are sales and marketing outrunning the leak?
Churn rate sizes the leak itself as a percentage, with no credit for growth. You want all three: churn rate to understand the leak, NRR to see whether existing customers offset it, and the quick ratio to see whether the business as a whole converts effort into durable revenue. A company can post a strong growth rate and a weak quick ratio at the same time — that combination is the classic signature of growth bought rather than earned.
How to Improve Your Quick Ratio
The ratio has only two levers, and the denominator is usually the cheaper one. Cutting monthly losses from $10,000 to $5,000 does the same thing to the ratio as doubling new MRR — and costs far less than doubling acquisition. In practice that means finding where accounts leave or downgrade (onboarding, a specific plan tier, a segment that never should have been sold), and fixing that before raising spend.
On the numerator, expansion revenue is the highest-leverage input: it lifts gains without adding acquisition cost, which is why land-and-expand businesses post the strongest quick ratios. Check whether growth is actually paying for itself with the CAC Calculator and the Payback Period Calculator — a healthy quick ratio paired with a long payback period still means growth is outrunning cash.
Efficient Growth Is Fundable Growth
The quick ratio is a durability test, which is exactly what a lender underwrites. A business adding $4 for every $1 it loses has recurring revenue that keeps showing up — the revenue is predictable enough to borrow against and repay from. A business at 1.2 has revenue that may not be there next year, and the same growth costs far more to sustain.
If your ratio is healthy and cash is the only thing capping how fast you can grow, that is the cleanest case for non-dilutive capital: fund sales, marketing, and product from future revenue instead of equity, and repay as that revenue arrives. Founderpath provides revenue-based financing to bootstrapped SaaS founders — capital priced off the durability your metrics already prove, with no dilution, board seats, or loss of control. Compare what that costs against an equity round with the Equity Dilution Calculator.

Your quick ratio proves the growth is durable.
Founderpath turns that durability into capital — without dilution.
A strong quick ratio means the recurring revenue you add keeps showing up. That is exactly what makes revenue borrowable: you can fund sales, marketing, and product from future revenue and repay as it arrives, instead of selling equity to buy growth you have already proven you can hold.
A business adding several dollars of MRR for every dollar it loses has predictable revenue — the durability lenders underwrite. Your quick ratio is the evidence, not a pitch deck.
Non-dilutive capital lets you invest in acquisition and expansion without cost cuts that hurt retention — so you lift gains while the churn side of the ratio stays where it is.
Revenue-based financing payments flex with revenue as it comes in, so the efficient growth your quick ratio measures keeps compounding instead of funding a fixed debt payment.
Compare your quick ratio, churn, and expansion against thousands of SaaS companies at your ARR stage — know whether the number is elite for your segment or just average.
No dilution, no board seats, no warrant coverage. You keep every point of upside your growth efficiency earns.

Example: a company adds $12,000 in new MRR and $4,000 in expansion while losing $3,000 to cancellations and $1,000 to downgrades. That is $16,000 ÷ $4,000 = a quick ratio of 4.0. Break your month into those four components first with the MRR Calculator.
