Monthly Recurring Revenue

Also: MRR

Definition. MRR is the normalized monthly recurring value of active customer contracts under a disclosed policy. One-time fees and services are separate. Report committed recurring revenue and variable usage separately, or disclose the usage normalization rule; billing and cash timing do not determine MRR.

Formula

Monthly Recurring Revenue identity

M R R_{t} = i \in active \sum \frac{p _{i}}{billing months _{i}}

Plain English: MRR = sum of all monthly subscription values (normalized from any billing cadence to monthly)

Notation: MRR_t = Σ(p_i / billing_months_i) for all active customers i

Benchmark by stage

Stage	Monthly Recurring Revenue	Notes
Seed	$0–$50k/month	Illustrative scale band; does not establish PMF, financing readiness or economic viability.
Series A	$50k–$500k/month	Illustrative scale band; does not establish PMF, financing readiness or economic viability.
Series B	$500k–$2M/month	Illustrative scale band; does not establish PMF, financing readiness or economic viability.
Growth / Series C+	$2M+/month	Illustrative scale band; does not establish PMF, financing readiness or economic viability.

Naive vs corrected

Version	Formula
Naive	Dividing multi-year total contract value by 12 treats several years of commitments as one annual run rate.
Corrected	Normalize the recurring portion of each active contract by its covered months. Separate one-time services and variable usage according to a consistent disclosed policy.

Common errors

Including one-time implementation fees in recurring revenue
Dividing multi-year total contract value by 12 instead of the covered months
Counting free trials or unsigned commitments as active recurring contracts
Changing usage normalization or currency policy without a reconciliation
Treating a cash refund as an automatic change to the contractual recurring rate

Where this sits

Part of the Economics & metrics (C4) cluster in the GTM World Model. Related to the model's "MRR_t = MRR_{t-1} + New + Expansion + Reactivation - Contraction - Churn, with disjoint monetary flows on one monthly and currency basis. Independent ending MRR is required to test reconciliation." equation.
