What does ARR stand for?

1. Annual Recurring Revenue (ARR)

Definition and Purpose

Annual Recurring Revenue (ARR) is a key metric used by subscription-based businesses to measure the predictable and recurring revenue generated over a year. It includes the revenue from subscriptions, maintenance contracts, and any other recurring income streams.

Components and Calculation

ARR is calculated by multiplying the monthly recurring revenue (MRR) by 12. For example, if a company has an MRR of $10,000, its ARR would be $120,000. This metric provides a clear picture of the company’s financial health and growth potential.


ARR is crucial for assessing the stability and scalability of a subscription-based business. It helps in forecasting revenue, evaluating business performance, and making informed strategic decisions.

ARR provides a quick estimate of an investment’s profitability and helps in making informed capital budgeting decisions. However, it does not consider the time value of money, which is a limitation compared to other metrics like Net Present Value (NPV) or Internal Rate of Return (IRR).

4. Autoimmune Rheumatic Disease (ARR)

Treatment and Management

Treatment aims to reduce inflammation, manage symptoms, and prevent joint damage. It may include medications, physical therapy, and lifestyle changes. Early diagnosis and appropriate management are crucial for improving outcomes.


ARRs significantly impact the quality of life and can lead to long-term disability if not properly managed. Awareness and early intervention are key to preventing severe complications and improving patient prognosis.

5. Average Room Rate (ARR)

Definition and Calculation

Average Room Rate (ARR), also known as Average Daily Rate (ADR), is a hospitality industry metric that measures the average revenue earned per occupied room per day. It is calculated by dividing the total room revenue by the number of rooms sold.
