Quick Ratio is the ratio of MRR Won to MRR Lost over a period. It's used by SaaS businesses to assess their growth efficiency.
This ratio shows how much you grow your recurring revenue relative to the revenue you're losing, indicating the health and sustainability of your growth. A value over 1 indicates you're adding MRR Won at a faster rate than you're losing MRR Lost, and vice versa.
MRR Won / MRR Lost
To calculate Quick Ratio, divide your Monthly Recurring Revenue (MRR) Won by MRR Lost for a specific period.
Focus on both acquiring new customers and retaining existing ones to maintain a healthy Quick Ratio; try not to focus solely on one. Work to increase the LTV of customers, as this will positively affect the MRR Won component.
This metric is not to be confused with the other 'Quick Ratio', also known as the Acid Test. This alternative metric measures your ability to meet short-term obligations with your most liquid assets.
