The MRR calculator breaks down your monthly recurring revenue into its component parts: new MRR from first-time customers, expansion MRR from upgrades and add-ons, contraction MRR from downgrades, and churned MRR from cancellations. Understanding your net new MRR and quick ratio tells you whether your SaaS business is growing efficiently. A quick ratio above 4 is considered excellent — it means for every dollar you lose, you're adding four dollars in new and expansion revenue. This tool is essential for SaaS founders preparing investor decks, tracking growth milestones, or simply understanding where their revenue comes from each month.

How to calculate MRR

Simple estimate: MRR = Customers × ARPU Net new MRR = New + Expansion - Contraction - Churn ARR = MRR × 12 Quick ratio = (New + Expansion) ÷ (Contraction + Churn)
