What is Monthly Recurring Revenue (MRR)?

Monthly Recurring Revenue (MRR) is a measure of the predictable and recurring revenue components of your subscription business. It's a key metric for subscription-based companies and SaaS businesses.

MRR Formula:

Number of Customers * Average Revenue per User (ARPU)

MRR helps in forecasting future revenue, measuring growth, and assessing the overall health of a subscription business. It's often used in conjunction with metrics like Customer Retention Rate and Customer Lifetime Value (CLV) to get a comprehensive view of business performance.

How is MRR calculated?

The MRR formula is simple: MRR = active subscribers × ARPU (Average Revenue Per User). If you have 200 active subscribers paying an average of $49 per month, your MRR is $9,800. Only recurring subscription revenue counts — one-time setup fees, professional services, and consulting revenue are excluded because they do not repeat next month and would inflate the number.

When your plans mix monthly and annual billing, normalize annual subscribers to their monthly value (annual price ÷ 12) before adding them in. Otherwise a single annual sale would spike MRR for the month it closed, then disappear. Most SaaS founders track MRR at the same day-of-month cutoff (typically the 1st) so month-over-month comparisons stay clean and expansion, contraction, and churn each get their own line on the MRR movement report.

What counts as recurring revenue?

Recurring revenue is revenue you can predict will repeat on a defined cadence (monthly or annually) from an existing paying customer, without a new sale motion. Subscription fees, seat expansions on the same subscription, and usage-based charges that repeat on the same billing cycle all count. Discounts and refunds reduce recurring revenue in the period they apply. Free trials and freemium seats do not count because there is no committed monthly amount attached.

Common items to exclude from MRR: one-time setup or onboarding fees, professional services engagements, hardware sales, transaction fees passed through to the customer, and any prepayment that has not yet been recognized. If you would not expect to invoice the same customer for the same amount next month by default, it does not belong in MRR. This is why ProfitWell and ChartMogul both warn against booking implementation revenue into MRR — it inflates the growth curve now and creates a cliff later.

MRR vs ARR: which should SaaS founders track?

MRR (Monthly Recurring Revenue) and ARR (Annual Recurring Revenue) measure the same underlying stream at different time slices. The conversion is direct: ARR = MRR × 12. If your MRR is $25,000, your ARR is $300,000. Neither is more accurate than the other — they emphasize different signals.

Track MRR when your customer base is mostly monthly-billed, when you ship product changes month-over-month, or when you need to see churn and expansion movement quickly. Track ARR when your customer base is majority annual, when you are pitching investors on an annual valuation multiple, or when a single deal is large enough to distort monthly comparisons. Most sub-$10M SaaS businesses report both internally and pick one headline number externally based on their sales motion. Use the Customer Retention Rate Calculator and CAC Calculator alongside MRR to get a full picture of unit economics.

Frequently Asked Questions

What's the difference between MRR and ARR? ▼

MRR (Monthly Recurring Revenue) and ARR (Annual Recurring Revenue) are closely related metrics. MRR measures your predictable revenue stream on a monthly basis, while ARR provides an annualized view. To convert MRR to ARR, simply multiply MRR by 12. For example, if your MRR is $10,000, your ARR would be $120,000.

How do I calculate ARPU? ▼

ARPU (Average Revenue per User) is calculated by dividing your total revenue by the number of users or customers. For MRR calculations, you'd typically use monthly revenue. For example, if your monthly revenue is $50,000 and you have 500 customers, your ARPU would be $100 ($50,000 / 500). Use our ARPU Calculator to calculate this.

Should I include one-time fees in MRR? ▼

Generally, one-time fees should not be included in MRR calculations. MRR should only include predictable, recurring revenue streams. One-time fees, such as setup fees or professional services, are typically excluded as they don't represent ongoing, predictable revenue.

How can I increase my MRR? ▼

To increase your MRR, consider these strategies:

Acquire new customers to increase your customer base
Reduce churn by improving customer retention (use our Customer Retention Rate Calculator)
Implement upselling and cross-selling to increase ARPU
Offer pricing tiers to capture different customer segments
Introduce annual plans with a discount to secure longer-term commitments

How does MRR relate to company valuation? ▼

MRR is a crucial metric for valuing subscription-based businesses. Investors often use a multiple of MRR or ARR to estimate a company's value. The specific multiple can vary based on factors like growth rate, churn rate, and market conditions. Generally, higher and more stable MRR leads to higher valuations.

What's the difference between MRR and revenue? ▼

MRR focuses specifically on the predictable, recurring portion of your revenue from subscriptions. It doesn't include one-time purchases, fees, or any non-recurring revenue. Total revenue, on the other hand, includes all income streams, both recurring and non-recurring. For subscription businesses, MRR provides a clearer picture of sustainable, long-term business health.

How does MRR impact other business metrics? ▼

MRR is closely tied to several other important business metrics:

Customer Lifetime Value (CLV): Higher MRR often correlates with higher CLV. Calculate your CLV using our CLV Calculator.
Customer Acquisition Cost (CAC): MRR helps determine how quickly you can recover your CAC. Use our CAC Calculator to compare.
Churn Rate: MRR lost to churned customers is a critical metric. Track this alongside your Customer Retention Rate.
Growth Rate: Month-over-month changes in MRR are a key indicator of business growth.

Did you know 80% of software features are rarely or never used? That's a lot of wasted effort.

SaaS software companies spend billions on unused features. In 2025, it was $29.5 billion.

We saw this problem and decided to do something about it. Product teams needed a better way to decide what to build.

That's why we created ProductLift - to put all feedback in one place, helping teams easily see what features matter most.

In the last five years, we've helped over 5,204 product teams (like yours) double feature adoption and halve the costs. I'd love for you to give it a try.
