What is ARR? Annual Recurring Revenue explained
ARR (Annual Recurring Revenue) measures the recurring revenue normalised to one year. Formula, examples, MRR conversion and how investors read it.
ARR (Annual Recurring Revenue) is the recurring revenue a subscription business expects to receive over a 12-month period. It’s the single number that frames every conversation about SaaS valuation, capital efficiency and growth velocity. If MRR is the heartbeat of your business, ARR is the annualised snapshot investors and board members anchor on.
This guide covers what ARR is, how to calculate it cleanly (including the traps), and how it relates to the metrics you already track.
What ARR is — and isn’t
ARR represents the recurring portion of revenue normalised to a year. It includes:
- Active subscriptions, regardless of monthly or annual billing
- Renewals expected from existing customers in the next 12 months
- Contracted expansion (upgrades, extra seats) that’s already signed
ARR does not include:
- One-time fees (setup, training, professional services)
- Pass-through transaction fees that aren’t margin to you
- Variable usage-based revenue that isn’t contracted as a minimum
The cleaner the definition, the more credible the ARR. Investors will dig into how you compute it during due diligence.
How to calculate ARR
The straightforward formula:
ARR = MRR × 12Where MRR is the recurring revenue normalised to one month across the entire active customer base. A worked example:
- 100 customers paying $50/month → MRR = $5,000 → ARR = $60,000
- 50 customers on a $600/year annual plan → MRR contribution = $50/month each × 50 = $2,500 → ARR from this cohort = $30,000
- A multi-year deal worth $36,000 over 3 years contributes $1,000/month MRR → $12,000/year of ARR
The second example is the trap most teams fall into. When a customer prepays $600 for an annual plan, it’s tempting to log $600 of revenue that month. That distorts your MRR / ARR. You must normalise it to $50/month.
Two flavours: Committed vs Contracted ARR
For B2B SaaS with multi-year deals, two sub-metrics matter:
- Contracted ARR — the ARR from contracts currently signed and in force. Includes contracted expansion that hasn’t kicked in yet (e.g. seat ramps that activate month 6).
- Committed ARR (cARR) — Contracted ARR plus signed-but-not-started deals (the “starting next quarter” book of business).
Most investors care about cARR for forward-looking deals and contracted ARR for the run-rate.
Why ARR matters
Three reasons it’s the headline SaaS metric:
- Valuation anchor. Public-market SaaS multiples are quoted as enterprise-value / ARR. The 2021 peak was around 20× ARR; current is 5-8× depending on growth + margin profile.
- Forward-looking visibility. Subscription contracts give you 12 months of revenue you can plan around — unlike one-time sales where you start each month at zero.
- Capital allocation. Knowing your ARR (and its growth rate) lets you fund headcount, ad spend and product investment against expected revenue, not guesswork.
ARR vs MRR — when to use which
| Metric | Best for | Why |
|---|---|---|
| MRR | Operational tracking, weekly stand-ups | Granular, picks up changes fast |
| ARR | Board reporting, investor pitches | Smooths out monthly volatility |
Internally, run on MRR. Externally, talk in ARR. The standard ARR-to-MRR ratio is exactly 12× — anything else is a flag that one of them is miscalculated.
ARR growth rate
ARR alone isn’t enough — what matters is how fast it’s growing.
ARR Growth Rate (annual) = (ARR_today − ARR_a_year_ago) / ARR_a_year_ago × 100Benchmarks by stage:
| Stage | Healthy ARR growth |
|---|---|
| Seed / pre-seed | Triple year-over-year (T3) |
| Series A | Triple → double (T2T2) |
| Series B / C | 100-200% YoY |
| Series D+ | 50-100% YoY |
| Public | 20-40% YoY |
The “triple, triple, double, double, double” path is the textbook trajectory for top-quartile SaaS.
Net New ARR and the components that move it
A flat ARR number hides a lot. Track Net New ARR each month:
Net New ARR = New + Expansion + Reactivation − Contraction − Churn- New ARR — first-time paying customers
- Expansion ARR — upgrades, extra seats, cross-sell to existing customers
- Reactivation ARR — churned customers who came back
- Contraction ARR — downgrades, seat reductions
- Churn ARR — customers who cancelled
If Net New ARR is positive and growing, you’re scaling. If it’s positive but flat, growth is decelerating. If it’s negative, you’re shrinking.
What ARR doesn’t tell you
Three blind spots to watch:
- Cash timing. ARR ignores whether customers pay annually upfront or monthly. Two companies with identical ARR can have wildly different cash positions.
- Quality of revenue. $1M ARR from 1,000 SMB customers at $1k each is different from $1M ARR from 5 enterprise logos at $200k each — different churn risk, different gross margin, different sales motion.
- Gross margin. ARR doesn’t tell you how much of each dollar drops to operating income. A 90% gross-margin business at $5M ARR is worth more than a 40% gross-margin business at $10M ARR.
Always pair ARR with: NRR, gross margin, CAC payback and net new ARR trend.
Common mistakes when reporting ARR
- Counting bookings as ARR. A signed contract that hasn’t started yet should sit in cARR (committed), not run-rate ARR.
- Treating one-time fees as recurring. Implementation fees, setup costs and training are not ARR.
- Annualising MRR from a single month. If May MRR is up 30% from April because of a big enterprise deal, your “ARR run-rate” jump is real for that customer but doesn’t represent the broader trend.
- Not subtracting confirmed churn. Customers who’ve signed termination notices but are still in their notice period should be excluded from contracted ARR.
FAQ
Is ARR the same as revenue?
No. ARR is the recurring annualised revenue. Reported revenue includes one-time fees, professional services and any non-recurring income.
Can a non-SaaS business have ARR?
Yes — any subscription business does. Streaming services, membership models, retainer-based agencies. As long as there’s a contracted recurring stream, ARR applies.
What ARR do I need for a Series A?
Two years ago the rule of thumb was $1M ARR with healthy growth. Today VCs invest earlier — $300-500k ARR can qualify if unit economics are clean (gross margin >70%, CAC payback <18 months, NRR >100%).
Does ARR include taxes / VAT?
No. Quote ARR net of VAT and any sales tax. Quoting it gross inflates the number against benchmarks.
