MRR Calculator FAQs

What is Monthly Recurring Revenue (MRR)?

Monthly Recurring Revenue (MRR) is the predictable revenue your business generates each month from subscriptions. It’s a core metric for SaaS and ecommerce subscription brands to track growth and financial health.

How do you calculate MRR?

MRR is calculated by multiplying the number of active customers by the average revenue per customer (ARPU), then adjusting for churn, expansion, and new customer growth over time.

Why is MRR important for ecommerce and SaaS?

MRR provides a clear view of recurring revenue, making it easier to forecast growth, measure retention, and evaluate the impact of pricing, marketing, and customer success strategies.

What is churn rate in MRR?

Churn rate is the percentage of recurring revenue lost each month due to cancellations. High churn reduces MRR and signals issues with retention or customer satisfaction.

What is expansion MRR?

Expansion MRR is additional revenue from existing customers through upgrades, add-ons, or increased usage. It’s a key driver of sustainable growth without acquiring new customers.

What is new MRR?

New MRR is revenue generated from newly acquired customers within a given month. It reflects the effectiveness of your acquisition and marketing efforts.

Can MRR decrease over time?

Yes, MRR can decline if churn and downgrades outweigh new and expansion revenue. Monitoring this helps identify when growth strategies need adjustment.

How can I increase my MRR?

You can grow MRR by acquiring more customers, reducing churn, increasing pricing, and driving expansion revenue through upsells and cross-sells.

How often should I track MRR?

MRR should be tracked monthly at a minimum. Many high-growth companies monitor it weekly to quickly identify trends and optimize performance.
