SaaS Quick Ratio Calculator

SaaS quick ratio measures growth efficiency by dividing revenue gains (new MRR plus expansion MRR) by revenue losses (churned MRR plus contraction MRR). A ratio above 1.0 means the company is growing. Below 1.0 means it is shrinking. This metric was developed by Mamoon Hamid at Social Capital to quickly assess growth quality.

Above 4.0 is considered healthy growth for a SaaS company according to Social Capital research. World-class companies achieve 4.0 or higher. A ratio between 2.0-4.0 is acceptable but indicates room for improvement in either growth or churn. Pre-Series A companies with a ratio below 2.0 may face challenges convincing investors that product-market fit has been achieved.

A quick ratio above 4.0 is considered healthy according to Mamoon Hamid of Social Capital. World-class SaaS companies achieve 4.0+. Ratios between 2.0-4.0 are acceptable but indicate room for improvement. Below 1.0 means the business is shrinking.

Early-stage startups should target a quick ratio above 4.0 because growth should significantly outpace churn at this stage. If your quick ratio is below 2.0 pre-Series A, investors will question whether product-market fit has been achieved.

Increase the numerator (new MRR + expansion MRR) through better acquisition and upselling, and decrease the denominator (churned MRR + contraction MRR) through better retention. Even small improvements in churn have outsized impact on the quick ratio.

Calculate monthly and track the trend over 6-12 months. A declining quick ratio over 3+ months signals worsening growth efficiency. Include it in your monthly metrics dashboard alongside MRR, churn, and NRR.

The SaaS quick ratio measures growth efficiency by dividing revenue gains (new + expansion MRR) by revenue losses (churned + contraction MRR). It matters because it shows whether your growth is sustainable, high growth with high churn is not healthy.

The five most important SaaS metrics are MRR (Monthly Recurring Revenue), monthly churn rate (target under 5%), LTV:CAC ratio (target 3:1 or higher), net revenue retention (target 100% or higher), and CAC payback period (target under 12 months).

Revenue growth rate equals (Current Period Revenue minus Prior Period Revenue) divided by Prior Period Revenue, times 100. The median SaaS company grows revenue 25% year over year with top-quartile companies growing 60% or more according to SaaS Capital data.

Unit economics measure the revenue and costs attributable to a single customer or transaction. The key metrics are CAC (cost to acquire one customer), LTV (total revenue from one customer), gross margin per customer, and contribution margin.

Right-size instances (most are over-provisioned by 40-60%), use reserved instances for predictable workloads (saves 30-60% versus on-demand pricing), implement auto-scaling to avoid paying for idle capacity, and delete unused resources like unattached storage volumes and idle load balancers.

Migration costs include planning and scoping labor (5-15% of total), data migration tooling and execution (20-30%), staff retraining (15-20%), integration rebuilding (20-30%), and lost productivity during the transition period (10-20%).
