You're walking into a planning meeting to pitch your new headcount strategy. Your sales team just landed a massive one-time contract, and the whole company is thrilled. But your stakeholders immediately zero in on a different metric. They want to see your annual recurring revenue (ARR).
One-time sales provide a great cash boost, but predictable revenue forms the foundation of a healthy SaaS business. ARR is the core metric that determines your company's valuation. It drives your fundraising conversations and gives you the true baseline you need to map out future spending. When you track your ARR accurately, you empower your scrappy finance team to forecast better. You stop guessing and start leading.
This guide covers exactly what ARR is, the formal definition, and how you can monitor it perfectly in Runway.
Definition and methodology of annual recurring revenue
ARR is the yearly value of all your active, contractually recurring subscriptions at one moment in time. Imagine your company running for the next 12 months with no changes, no new customers, no churn, no upgrades or downgrades. That’s ARR.
Here's the standard way to do it:
ARR = MRR × 12
Or, you can add up the yearly value of every active subscription contract. Both approaches should give you the same number if your data’s accurate.
ARR is a snapshot. It’s not a running total. You look at what’s active right now, not what you earned over time. This is important for comparing periods or showing your numbers to investors.
What’s in ARR matters as much as what’s out. ARR includes things like recurring subscription fees, contracted usage minimums, and recurring add-ons. It does not include one-time setup fees, services, or usage overages. Those are variable and not contractually promised. ARR is about committed, predictable revenue only.
You need consistent timing. The best practice is to recognize ARR when the contract starts, not at go live, invoice, or payment. Make a rule and follow it for every contract and every period. If you calculate ARR from MRR, use the same logic. Pick a starting point and stick to it. Runway's MRR guide covers more details on this.
Why ARR is crucial for SaaS: Strategic importance
ARR matters for more than reporting. It sets your company’s value.
Most SaaS valuations use ARR multiples. In 2025, high-growth SaaS companies are usually valued at five to ten times ARR, and top performers get even higher multiples. Growing ARR by 10% can increase your valuation quickly. Every dollar in ARR counts, and so does accuracy.
ARR guides your plans. Use ARR per employee to check your company’s efficiency. New ARR per sales rep tells you about sales productivity. CAC versus new ARR measures if your acquisition engine works. ARR is at the core of these ratios.
When you present to your board or investors, break ARR down by what’s new, what expanded, and what you lost to churn. Gaps or confusion can quickly erode confidence. Runway's ARR bridge guide points out that saying "ARR grew from $12M to $14.5M" doesn’t mean much if you lost 10% to churn along the way.
Advanced methodologies and approaches
ARR waterfall (bridge) analysis
The ARR bridge shows how net new ARR breaks down. Here’s the simple formula:
Beginning ARR + New ARR + Expansion ARR − Contraction ARR − Churned ARR = Ending ARR
This turns your growth number into a clear story. See if your growth is from new customers, expansion, or both. Spot where revenue is leaking. For example, if your expansion almost matches new ARR, you have strong retention and a product people want more of. That tells a different story than relying on new customers to make up for high churn.
Dig deeper by breaking down the bridge by segment. The dynamics in enterprise accounts often don’t match mid-market trends.
Committed ARR vs. live ARR
Committed ARR (CARR) includes signed contracts even if they’re not active yet. Live ARR counts only contracts generating recognized revenue right now. The difference matters most for long implementation timelines.
For example, a $120,000 annual contract with three months of setup shows up as $0 in live ARR for three months. Then, when it goes live, you see the jump. If you track only live ARR, you might miss deals in limbo or misread churn. Report committed and live ARR separately. Flag any deals signed but not live after 90 days for a close look.
ARR by cohort vintage
Segment ARR by when customers joined, such as by quarter or year. This surface trends that topline numbers miss. You’ll spot if, for example, your March customers are expanding, or if your 2022 group is shrinking.
Cohort analysis helps you forecast. If your 2022 cohorts keep 90% of ARR and 2024 cohorts keep just 75%, dig into why before you build next year’s plan.
Weighted ARR forecasting
Weighted forecasting doesn’t guess a single ARR number. It assigns probabilities to open deals based on their sales stage and history, applies likely renewal rates for current ARR, and factors in expansion with real assumptions. This shows a range, not just one outcome.
This relies on accurate CRM data and real conversion rates. Many SaaS companies overestimate their pipeline by including deals that haven’t had a meaningful conversation. Clean data gives you forecasting you can trust. Read more about forecasting gaps.
Usage-based ARR normalization
In usage-based models, there isn’t a fixed amount to annualize. The best way is to take the average of the last three months’ recurring usage revenue and multiply by 12. For seasonal businesses, use the past year.
- Segment by predictability. Enterprise customers with set minimums go into ARR.
- Pay-as-you-go customers should be kept separate until usage levels out.
- Some teams track “committed ARR” to keep trends clear.
Runway’s ARR bridge guide recommends this approach for hybrid models.
Key ARR components and considerations
New logo ARR
New logo ARR is ARR from new customers in a period. This tracks how effective you are at bringing in new business. For newer companies, most of your new ARR comes from new logos. It directly affects CAC and payback calculations.
Expansion ARR
Expansion ARR is growth from current customers, such as upsells, seat increases, or price bumps at renewal. Expansion is efficient because you don’t pay to acquire these customers. Recent data shows expansion ARR is 40% of all new ARR, rising to over 58% for bigger companies. Top SaaS businesses get more from expansion than new signups.
Contraction ARR
Contraction ARR is revenue lost when customers downgrade. That could be fewer seats, a cheaper tier, or bigger discounts. The customer is still active, just paying less. Contraction often points to value gaps or increased competition. Track contraction separately from churn. You need a different retention strategy for downgrades than for full cancellations.
Churned ARR
Churned ARR is ARR lost from customers who leave completely. This is the hole you need to keep filling with new and expanding customers. But not all churn is equal. Voluntary churn (the customer’s choice) is different from involuntary churn (failed payments, expired cards). Tag each clearly to focus your efforts where they matter.
Essential strategic relationships
ARR and net revenue retention
Net revenue retention (NRR) measures ARR change from your existing customers: expansion, minus contraction and churn, divided by starting ARR. Even companies showing good ARR growth can have falling NRR if they rely too much on new customer sales. That’s an expensive habit.
Here’s the NRR formula:
NRR = (Starting ARR + Expansion ARR − Contraction ARR − Churned ARR) / Starting ARR × 100
Runway’s NRR guide shows how NRR feeds into valuation:
valuation = ARR × growth rate × NRR × 10
A 1% bump in NRR grows value over time.
ACV vs. TCV distinctions
Annual contract value (ACV) is the annualized amount for a contract. Total contract value (TCV) is the total over the deal’s life, plus fees. Use ACV to calculate ARR. TCV gives you a bookings picture. Don’t add ACV totals to ARR or use TCV instead of ARR on multi-year deals, you’ll overstate your true run rate.
ARR and the rule of 40
The rule of 40 combines ARR growth rate and free cash flow margin as a benchmark. ARR growth rate is half of it. Runway’s rule of 40 guide explains that you need to choose between ARR growth or total revenue growth when using this measure. ARR isn’t perfect for usage-based models where revenue can shift a lot. Median rule of 40 for public SaaS in Q4 2025 was just 28%, with only 20% topping the benchmark.
Benchmarks and rules of thumb
Growth rate expectations by stage
ARR growth targets get lower as you get bigger. Seed-stage and Series A companies should go for three times year-over-year. Series B is usually 2–2.5x. At $50 million ARR and up, healthy growth is 30–50% per year.
SaaS Capital’s 2026 benchmarks show VC-backed companies growing 25–30% on average. The top quarter hit 50% or better. Bootstrapped companies average 20–23%. Good growth is relative. Growing 50% at $1 million ARR isn’t enough. Growing 50% at $100 million ARR is outstanding.
ARR per employee as an efficiency barometer
ARR per employee shows how much recurring revenue each team member supports. Best SaaS companies target $150,000 to $250,000 per employee. SaaS Capital data pegs the median at $130,000, with the $20–50 million ARR group hitting around $175,000 per employee.
Investors look at this ratio to compare efficiency. AI-native teams are already seeing much higher productivity on this measure, raising the bar for everyone.
Common pitfalls
Including non-recurring revenue in ARR
About 40% of SaaS companies calculate ARR wrong by including non-recurring revenue like setup fees, training, or professional services. Even if you sell those every year, they aren’t contractually recurring. Diligence will spot this and may require a restatement. Keep these numbers clean.
Mishandling multi-year contracts
A $240,000 two-year deal adds $120,000 to ARR, not $240,000. Including the total contract value inflates ARR and investors catch it fast. For multi-year contracts with different yearly values, choose a method: current-year value or the average per year. Both work if you apply your method consistently and explain it clearly.
Inconsistent churn recognition timing
Recognizing new bookings in ARR at contract signing but waiting to count churn until the contract expires creates a timing mismatch. This inflates ARR for a while and hides churn issues. Use the same timing for recognizing both. Track contraction and churn separately. They tell you different things about customer health.
How to track and forecast ARR in Runway

ARR waterfall and cohort dashboards
Once your data is connected, Runway auto-categorizes ARR into new, expansion, contraction, and churn using these formulas:
- new ARR:
if(ARR.last_month == 0 AND ARR > 0, ARR, 0) - expansion ARR:
if(ARR > ARR.last_month AND ARR.last_month != 0, ARR - ARR.last_month, 0) - contraction ARR:
if(ARR < ARR.last_month AND ARR != 0, ARR - ARR.last_month, 0) - churned ARR:
if(ARR == 0 AND ARR.last_month != 0, ARR.last_month, 0)
These formulas roll up into company-level metrics. Tag contracts by segment, product, or region to break down the bridge however you need. Cohort dashboards let you track customer performance over time, growth, retention, revenue, all with Runway's cohort modeling.
