ARR vs MRR: SaaS Revenue Metrics Explained Simply
Did you know that SaaS companies with strong MRR growth are 21% more likely to secure funding? Knowing your revenue metrics is kind of a big deal, especially if you're running a Software as a Service (SaaS) business. It's like knowing the score in a game – you can't win if you don't know where you stand. In this article, we'll break down two super important metrics: ARR (Annual Recurring Revenue) and MRR (Monthly Recurring Revenue). We'll make it easy to understand how to calculate them, why they matter, and how to use them to grow your business. Let's dive in!
Introduction to SaaS Revenue Metrics
SaaS revenue metrics are the bread and butter of understanding your company's financial health. They tell you how much money is coming in regularly, which helps you make smart decisions about where to invest your time and resources. Think of them as the dashboard in your car – they give you real-time information about your speed, fuel level, and engine performance. Without these metrics, you're driving blind.
Why Revenue Metrics Are Vital for SaaS Growth
Why should you even bother with revenue metrics? Well, they're crucial for a bunch of reasons:
Forecasting: They help you predict future revenue, which is essential for planning and budgeting.
Decision-Making: They guide decisions about pricing, marketing, and product development.
Investor Relations: Investors want to see consistent growth, and these metrics prove you're on the right track.
Performance Tracking: They show you how well your business is doing over time.
Basically, revenue metrics are like a compass for your SaaS business, pointing you toward growth and success.
Common Confusion Around ARR and MRR
Now, here's where things can get a little confusing. ARR and MRR are often used interchangeably, but they're not the same thing. They both measure recurring revenue, but over different time periods. It's like measuring distance in miles versus kilometers – both tell you how far you've gone, but in different units. We'll clear up the confusion and show you how to use each one effectively.
What is MRR (Monthly Recurring Revenue)?
Let's start with MRR. It's the amount of revenue you can expect to receive every month from your subscriptions. It's a snapshot of your monthly financial performance and helps you understand your short-term revenue trends.
Definition and Core Concept
MRR, or Monthly Recurring Revenue, is the total revenue you expect to receive from subscriptions each month. It only includes revenue that is recurring, meaning it comes in regularly from paying customers. It excludes one-time fees, like setup costs or consulting fees. MRR provides a consistent, month-by-month view of your business's revenue generation.
How MRR Reflects Monthly Performance
MRR is like a monthly report card for your business. It shows you how well you're acquiring new customers, retaining existing ones, and growing your revenue. By tracking MRR, you can quickly identify trends and make adjustments to your strategy. For example, if you see a dip in MRR, you know you need to focus on improving customer retention or boosting sales.
To get a complete picture of your monthly performance, it's important to understand the different types of MRR:
New MRR: Revenue from new customers acquired in the month.
Expansion MRR: Additional revenue from existing customers who have upgraded their subscriptions or added more users.
Churned MRR: Revenue lost from customers who have canceled their subscriptions.
Net New MRR: The total change in MRR for the month, calculated as (New MRR + Expansion MRR) - Churned MRR.
Understanding these different types of MRR helps you pinpoint where your revenue is coming from and where you need to improve.
What is ARR (Annual Recurring Revenue)?
Now, let's talk about ARR. It's the annualized value of your recurring revenue. Basically, it's MRR multiplied by 12. ARR gives you a bigger picture view of your revenue and is useful for forecasting and long-term planning.
Definition and Core Concept
ARR, or Annual Recurring Revenue, is the total revenue you expect to receive from subscriptions over a year. It's calculated by multiplying your MRR by 12. ARR is a key metric for SaaS businesses because it provides a clear view of your company's overall financial health and growth potential.
ARR as a Forecasting Tool
ARR is a powerful tool for forecasting future revenue. By tracking your ARR over time, you can identify trends and make predictions about your future performance. This helps you set realistic goals, allocate resources effectively, and make informed decisions about your business strategy.
When and Why to Use ARR Over MRR
ARR is particularly useful for businesses with annual contracts or long-term subscription plans. It gives you a more stable and predictable view of your revenue compared to MRR, which can fluctuate more from month to month. ARR is also favored by investors because it provides a clear picture of your company's long-term growth potential.
Key Differences Between ARR vs MRR
Okay, let's get down to the nitty-gritty. Here's a breakdown of the key differences between ARR and MRR:
Timeframe and Frequency
The most obvious difference is the timeframe. MRR looks at revenue on a monthly basis, while ARR looks at revenue on an annual basis. MRR is updated monthly, while ARR is typically updated quarterly or annually.
Use Cases and Business Stages
MRR is more useful for early-stage SaaS businesses that are focused on month-to-month growth. It helps them track their progress and make quick adjustments to their strategy. ARR is more useful for growth-stage and enterprise SaaS businesses that have longer sales cycles and annual contracts. It provides a more stable and predictable view of their revenue.
Here's a table summarizing the use cases:
Strategic Planning and Reporting Impact
MRR is great for short-term strategic planning, like setting monthly sales targets or launching new marketing campaigns. ARR is better for long-term strategic planning, like forecasting revenue for the next year or making decisions about product development. ARR is also the metric that investors pay the most attention to, as it gives them a clear picture of your company's growth potential.
How to Calculate MRR
Calculating MRR is pretty straightforward. Here's how:
Simple MRR Formula
The basic formula for calculating MRR is:
MRR = (Number of Customers) x (Average Revenue Per Customer)
For example, if you have 100 customers paying an average of $50 per month, your MRR would be $5,000.
Examples of MRR Calculation
Let's look at a few more examples:
Example 1: 50 customers paying $100/month = $5,000 MRR
Example 2: 200 customers paying $25/month = $5,000 MRR
Example 3: 75 customers paying $67/month = $5,025 MRR
As you can see, the formula is simple, but the results can tell you a lot about your business.
Tracking MRR Over Time
To get the most out of MRR, you need to track it over time. This will help you identify trends and patterns in your revenue. You can use a spreadsheet or a SaaS finance tool to track your MRR each month. Make sure to also track the different types of MRR (new, expansion, churned, and net new) to get a complete picture of your monthly performance.
How to Calculate ARR
Calculating ARR is even easier than calculating MRR.
ARR Calculation Formula
The formula for calculating ARR is:
ARR = MRR x 12
Simply multiply your monthly recurring revenue by 12 to get your annual recurring revenue.
Converting MRR to ARR
For example, if your MRR is $5,000, your ARR would be $60,000. This gives you a quick snapshot of your expected annual revenue based on your current monthly performance.
When the ARR Calculation Breaks Down
It's important to note that the ARR calculation assumes that your MRR will remain constant throughout the year. In reality, your MRR will likely fluctuate from month to month. This means that your actual annual revenue may be different from your calculated ARR. To get a more accurate forecast, you should consider factors like seasonality, churn, and expansion when calculating your ARR.
Here's a table summarizing the formulas:
Understanding the Revenue Mix
To get a clear picture of your financial health, it's important to understand the different types of revenue you're generating.
Recognizing One-Time vs Recurring Revenue
Recurring revenue is the revenue you receive regularly from subscriptions. One-time revenue is the revenue you receive from one-off transactions, like setup fees or consulting fees. Only recurring revenue should be included in your MRR and ARR calculations.
Avoiding Mistakes in ARR/MRR Reporting
One of the biggest mistakes you can make is including one-time revenue in your MRR and ARR calculations. This will inflate your numbers and give you a false sense of your company's financial health. Make sure to only include recurring revenue in your calculations.
Which Metric Should You Use – ARR or MRR?
So, which metric should you focus on? It depends on your business and your goals.
Early-Stage SaaS Businesses
Early-stage SaaS businesses should focus on MRR. It gives them a clear picture of their month-to-month growth and helps them make quick adjustments to their strategy. MRR is also easier to track and calculate when you're just starting out.
Growth-Stage and Enterprise SaaS
Growth-stage and enterprise SaaS businesses should focus on ARR. It provides a more stable and predictable view of their revenue and is favored by investors. ARR is also useful for long-term strategic planning and forecasting.
Investor Preferences and Reporting
Investors typically prefer to see ARR because it gives them a clear picture of your company's long-term growth potential. However, they will also want to see your MRR to understand your month-to-month performance. It's important to track and report both metrics to give investors a complete picture of your business.
Practical Examples and Scenarios
Let's look at a few practical examples to see how ARR and MRR are used in different scenarios.
Startup with Monthly Subscriptions
Imagine you're running a startup with monthly subscriptions. You have 500 customers paying an average of $20 per month. Your MRR is $10,000, and your ARR is $120,000. By tracking these metrics, you can see how your business is growing month over month and year over year.
Enterprise SaaS with Annual Contracts
Now, imagine you're running an enterprise SaaS business with annual contracts. You have 50 customers paying an average of $10,000 per year. Your ARR is $500,000. In this case, ARR is the more important metric because it gives you a clear picture of your company's long-term revenue.
Mixed Billing Models – How to Handle
What if you offer both monthly and annual plans? In this case, you need to calculate your MRR and ARR separately for each type of plan. For monthly plans, you can use the standard MRR formula. For annual plans, you can divide the annual revenue by 12 to get the equivalent MRR. Then, add up the MRR from both types of plans to get your total MRR. Finally, multiply your total MRR by 12 to get your ARR.

ARR & MRR and Their Role in Valuation
ARR and MRR are super important when it comes to valuing your company.
Why Investors Care About Recurring Revenue
Investors love recurring revenue because it's predictable and sustainable. It shows that your business has a solid foundation and is likely to continue growing in the future. Companies with high recurring revenue are typically valued higher than companies with low recurring revenue.
How Recurring Metrics Affect Company Value
Recurring metrics like ARR and MRR are used to calculate your company's valuation multiple. This multiple is then multiplied by your ARR or MRR to determine your company's overall value. The higher your recurring revenue, the higher your valuation. According to research, SaaS companies with $1 million to $10 million in ARR are typically valued at 3 to 5 times their ARR. It's also a fact that companies focusing on ARR see 2x higher growth rates.

Common Mistakes to Avoid
There are a few common mistakes that SaaS businesses make when tracking ARR and MRR.
Overestimating Revenue
One of the biggest mistakes is overestimating revenue. This can happen when you include one-time fees in your MRR and ARR calculations or when you don't account for churn. Be realistic about your revenue and make sure to only include recurring revenue in your calculations.
Misclassifying Contract Types
Another common mistake is misclassifying contract types. Make sure you understand the difference between monthly and annual contracts and calculate your MRR and ARR accordingly. If you offer both types of plans, calculate your MRR and ARR separately for each plan.
Ignoring Churn and Downgrades
Churn and downgrades can have a significant impact on your MRR and ARR. Make sure to track churn and downgrades carefully and factor them into your calculations. Ignoring churn and downgrades will give you a false sense of your company's financial health.
Here's a table summarizing common mistakes:
