What is Monthly Recurring Revenue (MRR)?

Monthly Recurring Revenue (MRR) is the predictable total revenue a subscription business expects to receive each month from all active paying customers.

Definition

Monthly Recurring Revenue (MRR) is the total predictable revenue that a business receives from all active subscription customers in a given month. It is one of the most important metrics for subscription-based businesses (SaaS, membership sites, subscription boxes, retainer agreements) because it represents recurring, contractually committed income that is less vulnerable to month-to-month fluctuation than one-time project revenue. MRR is used by investors to evaluate the health and growth trajectory of subscription businesses, and by business owners to forecast cash flow and plan operations.

How to Calculate MRR

The basic MRR formula is: MRR = Number of Active Customers × Average Revenue Per User (ARPU) per month. For a business with 50 clients on monthly retainer at an average of $1,200/month: MRR = 50 × $1,200 = $60,000/month. More detailed MRR components include New MRR (revenue from new customers acquired this month), Expansion MRR (additional revenue from existing customers who upgraded), Churned MRR (revenue lost from customers who cancelled or downgraded), and Net New MRR (New MRR + Expansion MRR - Churned MRR).

Types of MRR

There are several categories of MRR that subscription businesses track. Standard MRR is revenue from regular monthly subscriptions with no special adjustments. Prepaid MRR is revenue from customers who pay annually upfront — this is recognized monthly as the service is delivered, but the cash is received upfront. Churned MRR tracks revenue lost from cancellations and downgrades. Expansion MRR tracks revenue gained from upgrades and add-ons. Net MRR is the net change in MRR over a period (new + expansion - churn). Net Revenue Retention (NRR) compares expansion to churn and is considered one of the best indicators of business health.

MRR vs. Revenue — Why They Are Different

MRR and total revenue are different because MRR only counts recurring subscription revenue, while total revenue includes one-time fees, implementation fees, professional services, and any non-recurring charges. A business might have $100,000 in total monthly revenue but only $60,000 in MRR. Investors in subscription businesses focus on MRR because it is more predictable and sustainable than one-time revenue. An MRR-focused business with 90% recurring revenue is generally valued at a higher multiple than a business with 40% recurring revenue and 60% project-based work.

MRR for Freelancers with Retainers

Freelancers who work on retainer agreements can apply the MRR concept to their own business. If you have 4 retainer clients paying $2,500, $3,000, $1,500, and $4,000 per month, your MRR is $11,000. Tracking MRR helps you understand your baseline monthly income and plan for growth by setting targets for new retainers and expansion revenue. If a retainer client downgrades, your MRR drops — this gives you an early warning signal of potential churn and helps you plan your business development efforts accordingly.

Frequently Asked Questions

What is MRR in business?

MRR (Monthly Recurring Revenue) is the predictable revenue that a business expects to receive every month from active subscription customers. It is calculated by multiplying the number of active paying customers by the average revenue per user (ARPU) per month. MRR is the core metric for subscription businesses and is used to track growth, forecast cash flow, and evaluate business health.

What is the difference between MRR and ARR?

MRR is Monthly Recurring Revenue (monthly basis); ARR is Annual Recurring Revenue (yearly basis). ARR is simply MRR multiplied by 12. Most subscription businesses track both: MRR for operational decisions (hiring, product roadmap) and ARR for investor reporting and valuation discussions. ARR is also used in enterprise SaaS contracts that are typically billed annually.

What is a good MRR growth rate?

For early-stage SaaS companies, a monthly MRR growth rate of 10–20% is considered excellent. For more mature companies, 5–10% monthly growth is very strong. Benchmarks vary by industry and business model. The key is not just growth rate but also net revenue retention (whether existing customers are expanding or churning) and customer acquisition cost payback period.
