Short Definition
Contraction ARR represents the annual recurring revenue (ARR) lost from existing customers who reduce their subscription value within a specific period, without fully terminating their contracts.
It covers tier/plan downgrades (Down-sell), fewer seats/units or a lower committed minimum (the least they’re contractually obligated to pay each year), and price-only cuts/discounts, and is one of the key indicators of retention pressure and recurring revenue stability.
Why it matters for Investors
Retention health: Shows how much ARR you’re losing from customers who stay but pay less.
Profitability concern: Higher Contraction ARR reduces ARR and can pressure margins.
Growth balance: Stacking contraction against expansion reveals whether the base is net growing or shrinking
Formula
Practical considerations:
ARR scope: Count ARR lost from existing customers who stay but pay less—plan/tier downgrades (Down-sell) and fewer seats/units or a lower committed minimum, or a lower unit price/price-only cut (Reduction). Exclude logo churn (to $0) and one-off credits.
Timing: Record on the effective (go-live/start) date; signed-not-live sits in CARR until it starts.
Definition clarity: Standardize terms - Down-sell = move to a lower tier/remove a paid module; Reduction = lower quantity/minimum or lower unit price. “Existing customer” = active contract (not churned).
Reversals: If undone within the same period, net to $0; if undone later, record as Expansion (or an Adjustment if correcting a prior period).
Reporting cycle: Measure consistently (monthly/quarterly), aligned to effective dates.
Worked Example
Starting ARR (Jan 31): $1,200,000
Contract log (February):
Account | Event | Effective by Feb 28? | Account ARR @ Feb-28 ($) | Δ ARR in Feb ($) | Category | Notes |
|---|---|---|---|---|---|---|
A | Renewal $100,000 → $80,000 (tier downgrade) | Yes | $80,000 | -$20,000 | Contraction — Down-sell | Lower plan at renewal |
B | Seats cut 200 → 170 @ $150/seat/yr | Yes | $25,500 ($30,000 → $25,500) | -$4,500 | Contraction — Reduction (qty) | Fewer seats |
C | Price-only cut: 100 seats $120 → $110 | Yes | $11,000 ($12,000 → $11,000) | -$1,000 | Contraction — Reduction (price) | Same qty, lower unit price |
D | New logo $24,000, starts Feb 5 | Yes | $24,000 | +$24,000 | New Logo | Not Contraction |
E | Expansion +$15,000 on existing | Yes | $55,000 ($40,000 → $55,000) | +$15,000 | Expansion | Upsell/add-on |
F | Churn: $30,000 → $0 (Feb 28) | Yes | $0 | -$30,000 | Churn (Logo Churn) | Logo to $0 |
G | Signed reduction $12,000, starts Mar 1 | No | $0 | $0 | Booking / CARR | Signed, not effective → March |
Contraction ARR (February): $25,500 = $20,000 (A) + $4,500 (B) + $1,000 (C)
ARR Bridge (February):
New Logo ARR: +$24,000 (D)
Expansion ARR: +$15,000 (E)
Contraction ARR: −$25,500 (A + B + C)
Logo Churn ARR: −$30,000 (F)
Net New ARR: $24,000 + $15,000 − $25,500 − $30,000 = −$16,500
Ending ARR (Feb 28): $1,200,000 − $16,500 = $1,183,500
Notes:
Contraction includes down-sells (feature/tier drop) and reductions (fewer units/minimum or price-only cuts).
Signed-not-live changes sit in CARR and don’t affect ARR until the effective date.
Logo Churn (to $0) is not Contraction; it’s reported separately in the bridge.
Best Practices
Accurate tracking: Use billing/subscription systems and CRM to monitor contraction events effective in the period (down-sells and reductions, including price-only cuts); reconcile to your ARR change log.
Regular updates: Recalculate Contraction ARR every reporting period; capture effective-date changes and any reversals.
Segmentation: Analyze by customer segment, product tier, or contraction reason to identify trends.
Retention strategy: Use Contraction ARR to address customer downgrades and optimize pricing.
FAQs
What is included in Contraction ARR?
ARR lost from existing customers who stay but pay less—down-sell (lower tier/remove a paid module) and reductions (fewer seats/units or a lower committed minimum, or price-only decreases)—counted when effective (goes live/start date).Can Contraction ARR increase?
Yes—if more/larger downgrades, quantity/minimum cuts, or price-only decreases take effect in the period.How is logo churn handled?
It is excluded from Contraction ARR. Logo churn = customer goes to $0 and is reported separately as Logo Churn ARR.Is it the same as Down-sell ARR?
No. Down-sell = tier/plan downgrade or removing a paid module. Contraction ARR = Down-sell ARR + Reduction ARR.What if a reduction is reversed?
If reversed within the same period, net to $0. If reversed after period close, record Expansion in the later period (or an Adjustment if correcting a prior period).
