Revenue metrics

Term	Definition
MRR	Monthly Recurring Revenue. The normalized monthly value of active subscriptions. Annual plans are divided by 12, and other billing intervals are converted to a monthly equivalent.
Normalized MRR	MRR converted to a common monthly basis across billing intervals and, where applicable, the workspace base currency.
CMRR	Committed Monthly Recurring Revenue. MRR adjusted for known future changes such as subscriptions set to cancel at period end or scheduled downgrades.
ARR	Annual Recurring Revenue. MRR multiplied by 12.
ARPA	Average Recurring Revenue per Account. Total MRR divided by active paying accounts.
NRR	Net Revenue Retention. The percentage of opening MRR from existing accounts retained at period end after expansion, contraction, and churn. Values above 100% mean expansion outweighed losses.
GRR	Gross Revenue Retention. The percentage of opening MRR retained after contraction and churn, excluding expansion. GRR is capped at 100%.
MRR growth rate	The percentage change in MRR over a reporting period, commonly month over month or year over year.
Net New MRR	Net MRR movement in a period: New MRR plus Expansion MRR plus Reactivation MRR minus Contraction MRR and Churned MRR.
New MRR	MRR from first-time paying accounts in the reporting period.
Expansion MRR	Additional MRR from existing accounts that upgraded, added subscription items, increased quantity, or moved to a higher priced plan.
Contraction MRR	MRR lost from existing accounts that downgraded, removed subscription items, reduced quantity, or moved to a lower priced plan.
Churned MRR	MRR lost when accounts cancel or otherwise leave active paid subscription status.
Reactivation MRR	MRR recovered when a previously churned account becomes active and paying again.
Delinquent revenue	MRR attached to subscriptions or invoices in failed payment states such as past_due or unpaid.
Revenue concentration	The share of total MRR represented by the largest accounts, such as the top 10 accounts.
MRR band / ARR band	A filter range that groups accounts by recurring revenue size.
Base currency	The reporting currency used when SubscriptionMonitor normalizes revenue from multiple Stripe currencies.

Retention and account health

Term	Definition
Customer churn rate	The percentage of paying accounts lost in a reporting period.
Revenue churn rate	The percentage of opening MRR lost to cancellations and contraction in a reporting period.
Opening MRR	The MRR from a set of accounts at the start of a reporting period, used as the denominator for retention and churn calculations.
Cohort	A group of accounts that share a starting event, usually the month their first Stripe subscription was created.
Revenue cohort retention	The percentage of a cohort’s original recurring revenue that remains after 1, 3, 6, 12, or more months.
Customer cohort retention	The percentage of accounts in a cohort that remain active after a given number of months.
Trial conversion rate	The percentage of accounts that move from Stripe trialing status to active paid status.
Renewal-at-risk	An account with a Stripe signal that could threaten future revenue, such as cancel_at_period_end, failed renewal payment, scheduled downgrade, or a high-value renewal coming soon.
Renewal exposure	The amount of ARR or MRR tied to upcoming renewals that may need attention.
Recently churned account	An account that cancelled or left active paid subscription status in the current or recent reporting period.
Win-back outreach	Follow-up with churned or at-risk accounts to recover revenue or prevent cancellation.
Tenure	How long an account has been active as a paying subscriber.
Delinquency status	Whether an account has failed payments, unpaid invoices, or other billing collection issues.

Forecasting and quantity analysis

Term	Definition
MRR forecast	A forward projection of MRR over future windows such as 3, 6, or 12 months.
Cohort-based projection	A forecast that uses observed revenue retention from existing cohorts to estimate future revenue.
Renewal Wall	A view of upcoming renewals weighted by ARR, useful for spotting concentrated renewal risk.
Scenario modeling	Adjusting assumptions such as churn, contraction, or expansion to compare upside and downside revenue outcomes.
Baseline forecast	The default projection based on current subscription trends and observed historical data.
Billing interval	How often a subscription is billed, such as monthly, quarterly, or annually.
Billing cycle anchor	Stripe’s timestamp that determines when a subscription’s billing period renews.
Subscription schedule	A Stripe object that defines planned future subscription changes, such as upgrades, downgrades, or phase changes.
Proration event	A Stripe billing adjustment created when a subscription changes mid-cycle.
Quantity-driven pricing	Pricing where subscription revenue depends on billed quantity, such as seats, licenses, or units.
Licensed quantity	The billed quantity attached to a subscription item, often representing seats or licenses.
Quantity expansion	An increase in billed quantity for an existing account.
Quantity contraction	A decrease in billed quantity for an existing account.
Quantity lens / quantity layer	A supporting Dashboard or Forecasting view that shows whether revenue movement came from billed quantity changes, price changes, or both.
Billed quantity band	A filter range that groups accounts by the number of billed units, seats, or licenses.

Alerts and digest

Term	Definition
Alert threshold	A configured value that determines when an alert fires, such as a churn percentage or minimum MRR loss.
Churn spike	An alert condition where customer churn rate or churned MRR exceeds the configured threshold.
MRR contraction alert	An alert condition where net MRR movement goes negative or contraction exceeds the configured threshold.
Payment failure cluster	An alert condition where more than a configured percentage of subscriptions have failed payments within a selected window.
Large renewal approaching	An alert condition for a high-value annual renewal coming within a selected time window.
Licensed quantity drop	An alert condition where a top account materially reduces billed quantity.
Weekly digest	A scheduled email summary of current MRR, net new MRR, churned MRR, top expansions, top contractions, upcoming renewals, and fired alert rules.
CSV export	A downloadable comma-separated file containing the currently filtered view from Dashboard, Retention, Account Explorer, or Forecasting.
