ARR
CRM & RetentionAlso: Annual Recurring Revenue
Quick definition
ARR stands for Annual Recurring Revenue. It is the annualised value of all active subscription contracts at a given point in time. Calculated by multiplying Monthly Recurring Revenue (MRR) by twelve, ARR gives a snapshot of the predictable revenue a subscription business expects to collect over the next twelve months if nothing changes.
This is your recurring revenue run-rate. It only holds if churn stays flat. Pair it with your net revenue retention rate to understand whether the number is compounding or eroding.
How it varies across Australia
ARR growth rates vary sharply by stage and model. Early-stage Australian SaaS businesses often report high growth rates from a small base, which can mask churn problems that only surface once the base grows. The businesses with the most reliable ARR are those where net revenue retention sits above one hundred percent, meaning expansion revenue outpaces churn.

ARR is the subscription economy's equivalent of a salary. It tells you what you expect to earn if every current customer stays and nothing changes. The 'if nothing changes' part is where the number becomes honest or dishonest depending on how you use it.
The maths is simple: take your Monthly Recurring Revenue (MRR) and multiply by twelve. What matters more than the formula is what you include. Only recurring, contracted revenue counts. One-off professional services fees, variable usage charges, and one-time setup costs do not belong in ARR. Including them flatters the number and misleads any investor or board member reading it.
ARR is a point-in-time snapshot. It measures the annualised value of what you have right now, not what you will actually collect. The gap between ARR and actual collected revenue is churn. Businesses with high ARR but high churn are running a leaky bucket. Businesses with modest ARR but strong retention and expansion are compounding.
For most Australian SaaS and subscription businesses, ARR is the primary metric investors, boards and acquirers will anchor to. Getting the definition clean before you start reporting it saves enormous pain later.
ARR is a snapshot, not a guarantee. The number only holds if your churn does.
How to calculate it
ARR = MRR × 12
Worked example. You have 80 customers paying an average of $850 per month. MRR = 80 × $850 = $68,000. ARR = $68,000 × 12 = $816,000. No one-off fees, no usage overages, no pending upsells included.
The Australian context
Australian SaaS businesses pricing in Australian dollars face a structural headache when reporting ARR to US-based investors who think in USD. The exchange rate gap means ARR comparisons against US benchmarks require an explicit currency note. A business at one million AUD ARR is not at one million USD ARR, and the difference matters when benchmarking against global cohorts.
Australian accounting standards also treat deferred revenue differently from US GAAP in some edge cases. If you are reporting ARR for a capital raise or acquisition, confirm with your accountant which revenue recognition rules apply to your contract structure before locking in a figure.

Common questions
What is the difference between ARR and revenue?
ARR is a forward-looking run-rate based on current contracted subscriptions. Revenue is what you actually collected in a given period. ARR can be higher than collected revenue if customers churn mid-year, or lower if you collected large upfront payments. They measure different things and should not be substituted for each other.
Can ARR shrink even when you're adding customers?
Yes. If new customers are on smaller plans than the customers churning, ARR falls even as headcount grows. This is why net revenue retention matters as much as new ARR. Track both expansion and contraction separately.
How is ARR used in business valuation?
SaaS businesses are often valued as a multiple of ARR, with the multiple depending on growth rate, net revenue retention, gross margin and market size. The ARR multiple is a shortcut, not a formula. It varies widely by stage, sector and market conditions.
Should early-stage businesses report ARR or MRR?
Both, but with different audiences. MRR is more useful internally for tracking momentum month to month. ARR is more useful externally for investor conversations. At early stage, be explicit that ARR is annualised from a small base and caveat it with your churn rate.
