Annual recurring revenue (arr)
Annual Recurring Revenue (ARR) is the total value of recurring subscription revenue normalized to a one-year period. For SaaS and subscription businesses, ARR is one of the most important metrics-it represents the predictable revenue the company expects to receive annually from its current customer base. It excludes one-time fees, professional services, and variable usage charges.
Why it matters
ARR represents the foundation of a subscription business. Unlike one-time revenue that must be constantly replaced, ARR compounds. A customer acquired today contributes to ARR this year, next year, and every year they remain a customer. This predictability makes ARR businesses valuable and plannable.
Investors pay close attention to ARR. Company valuations often use ARR multiples-a company might be worth 5x, 10x, or 20x its ARR depending on growth rate, market, and other factors. Understanding and growing ARR directly affects company value.
ARR also enables confident planning. When you know how much recurring revenue you have, you can plan hiring, investment, and operations with greater certainty than businesses with unpredictable revenue.
Calculating arr
The basic formula is simple:
ARR = Monthly Recurring Revenue (MRR) × 12
Or if you have annual contracts:
ARR = Sum of all annual subscription values
For accurate ARR calculation, include only recurring subscription revenue. Exclude one-time setup fees, professional services, usage overages (unless committed minimums), and non-recurring charges.
Arr components
Understanding ARR movement requires tracking its components:
New ARR comes from customers acquired during the period. A new customer signing a $12,000 annual contract adds $12,000 in new ARR.
Expansion ARR comes from existing customers who upgrade, add users, or purchase additional products. A customer who upgrades from $10,000 to $15,000 annually adds $5,000 in expansion ARR.
Churned ARR is lost when customers cancel. A customer who cancels a $12,000 contract removes $12,000 in churned ARR.
Contraction ARR is lost when existing customers downgrade. A customer who moves from $15,000 to $10,000 annually creates $5,000 in contraction ARR.
Net New ARR = New ARR + Expansion ARR - Churned ARR - Contraction ARR
This breakdown reveals the health of your business. Relying entirely on new ARR indicates retention problems. Strong expansion ARR suggests product-market fit and upselling success.
Arr and retention
Net Revenue Retention (NRR) measures how ARR from existing customers changes over time:
NRR = (Starting ARR + Expansion - Churn - Contraction) / Starting ARR × 100
An NRR above 100% means expansion exceeds losses-your existing customer base grows without any new sales. Top SaaS companies achieve 120%+ NRR, meaning they could stop acquiring new customers and still grow revenue.
NRR below 100% means you're losing revenue from existing customers. You must constantly acquire new customers just to stay flat. This is common in SMB-focused businesses with higher churn but problematic if the gap is large.
Arr benchmarks
What constitutes "good" ARR growth depends on stage and context:
Early stage (under $1M ARR): Growth rate matters more than the number. 2-3x annual growth indicates traction. Many successful companies at this stage don't track ARR formally yet.
Growth stage ($1M-$10M ARR): 50-100%+ annual growth is strong. Net revenue retention becomes important. ARR efficiency (ARR per employee) starts mattering.
Scale stage ($10M+ ARR): 30-50% growth is solid; higher is exceptional. Efficiency metrics become critical. The path to profitability becomes relevant.
Common mistakes
Including non-recurring revenue inflates ARR and misleads stakeholders. Be strict about what counts as recurring.
Counting committed but not active revenue misrepresents current state. If a customer signed but hasn't started paying, that's bookings, not ARR.
Inconsistent calculation across teams creates confusion. Define ARR precisely and ensure everyone calculates it the same way.
Ignoring cohort dynamics misses important trends. Overall ARR might look fine while recent cohorts perform poorly. Segment analysis reveals underlying health.
Celebrating ARR without profitability context can mislead. ARR is important, but if you're losing money on every customer, more ARR just means more losses.
Using arr
For planning, ARR provides a foundation for budgeting and hiring. If you expect 50% ARR growth and know your revenue-per-employee benchmarks, you can plan team growth accordingly.
For fundraising, ARR and growth rate significantly influence valuation. Higher ARR with strong growth commands higher multiples.
For product decisions, understanding which features drive expansion versus which correlate with churn informs prioritization. Features that increase ARR deserve attention.
For sales, ARR targets align incentives with company goals. Commission structures often tie to ARR contribution.
Klero helps teams understand what drives ARR by connecting customer feedback to retention and expansion. When you can see what retained customers say versus churned customers, you understand what to build to protect and grow ARR.
