Key Takeaways

MRR is the lifeblood of SaaS
Monthly Recurring Revenue provides predictable financial modeling, allowing startups to forecast cash flow and plan long-term investments confidently.
Net New MRR dictates actual growth
Gaining $5,000 in new sales means nothing if you lose $6,000 to cancellations. Net New MRR shows your true directional momentum.
Retention is cheaper than acquisition
Reducing your Churned MRR has a compounding effect on your overall revenue growth. Focusing on expansion (up-sells) and minimizing churn is critical.

What is MRR & How to Calculate it?

Monthly Recurring Revenue (MRR) is the predictable, normalized revenue a business expects to earn every month from its active subscription base. It is the definitive metric for any Software-as-a-Service (SaaS) or subscription-based business model. To see how your MRR stacks up against industry medians, compare it against our 2026 SaaS benchmarks hub.

Unlike traditional retail sales, SaaS relies on recurring payments. Calculating MRR enables investors, founders, and growth marketers to measure momentum independently of varying billing cycles (e.g., mixing monthly and annual subscriptions).

Frequently Asked Questions

What is a good MRR growth rate for a startup?

For early-stage SaaS startups (under $1M ARR), a 15% to 20% month-over-month (MoM) growth rate is considered excellent. Once you scale past $1M ARR, a healthy MRR growth rate usually stabilizes between 5% and 10% MoM.

What is the "Rule of 40" in SaaS?

The Rule of 40 is a principle used by VCs to measure the health of mature SaaS companies. It states that your Revenue Growth Rate (%) + Profit Margin (%) should equal or exceed 40%. If your MRR is growing fast, it's okay to burn cash; if growth slows, you must show profitability.

How is MRR different from ARR?

MRR is your Monthly Recurring Revenue. ARR is Annual Recurring Revenue. The formula is simple: ARR = MRR × 12. Do not include one-time setup fees or consulting charges in your MRR calculations, as they do not recur.

What counts as recurring revenue?

Recurring revenue includes subscription payments that repeat monthly or annually. One-time setup fees, consulting projects, implementation charges, and custom development work should not be included in MRR calculations because they are not predictable recurring income.
