How do I calculate MRR for my SaaS?

What is net new MRR and why does it matter?

What is a good SaaS Quick Ratio?

A Quick Ratio above 4 is considered healthy. You add $4 for every $1 lost to churn. Between 2 and 4 is moderate growth with room for improvement. Below 1 means your business is shrinking. The industry average in 2026 is around 1.82, meaning most SaaS companies barely outrun their churn.

How do I improve my MRR growth without spending more on acquisition?

Focus on reducing churn and increasing expansion revenue. Every dollar you prevent from churning has the same effect as a dollar of new revenue but costs 5-7x less. Add upgrade paths, per-seat pricing, or usage tiers to capture more value from existing customers.

What are the four components of MRR?

MRR breaks into new MRR (first-time customers), expansion MRR (upgrades and seat additions), churned MRR (cancellations), and contraction MRR (downgrades). Tracking each component separately helps you identify exactly where your growth is coming from and where it is leaking.

What is MRR?

Monthly Recurring Revenue is the predictable revenue your SaaS earns every month from active subscriptions. It excludes one-time payments, setup fees, and non-recurring charges. MRR is the single most important metric for understanding the health and trajectory of a subscription business because it strips away noise and shows you the recurring engine underneath.

MRR breaks down into four components. New MRR comes from first-time customers. Expansion MRR comes from existing customers upgrading, adding seats, or increasing usage. Churned MRR is revenue lost when customers cancel entirely. Contraction MRR is revenue lost when customers downgrade but stay. Net new MRR; the number that determines whether you are growing or shrinking. is the sum of new plus expansion minus churned minus contraction.

Your ARR (Annual Recurring Revenue) is simply your ending MRR multiplied by 12. While ARR is useful for annual planning and fundraising conversations, MRR is the operational metric you should track weekly or monthly. Changes in MRR give you faster signal about what is working and what is broken than waiting for ARR to move.

What's a healthy Quick Ratio?

The SaaS Quick Ratio measures growth efficiency by dividing incoming MRR (new + expansion) by outgoing MRR (churned). A Quick Ratio of 4.0 or higher is considered healthy. It means you are adding $4 of new revenue for every $1 you lose. The industry average in 2026 hovers around 1.82, which means most SaaS companies are barely outrunning their churn.

A Quick Ratio below 1.0 means your business is shrinking. You are losing more MRR than you are adding. Between 1.0 and 2.0 is weak growth that will stall at scale because acquisition costs increase while churn stays constant. Between 2.0 and 4.0 is moderate growth with room for improvement. Above 4.0 means your growth engine is efficient and sustainable.

The fastest way to improve your Quick Ratio is not to spend more on acquisition. It is to reduce churn. Every dollar you prevent from churning has the same effect on net MRR as a dollar of new revenue, but it costs significantly less to retain an existing customer than to acquire a new one. See our retention vs acquisition cost calculator for the math. Most estimates put the cost difference at 5x to 7x. Start by addressing involuntary churn from failed payments, then tackle voluntary churn with cancel flows.
