Monthly Recurring Revenue
Also: MRR
Definition. MRR is the sum of all normalized monthly subscription values from active customers at a point in time. It excludes one-time fees, professional services, and usage overages. Best-in-class SaaS companies track MRR to within 1–2% accuracy.
Formula
Monthly Recurring Revenue identity
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

| Stage | Monthly Recurring Revenue | Notes |
|---|---|---|
| Seed | $0–$50k/month | Pre-product-market fit; focus on signal not scale |
| Series A | $50k–$500k/month | PMF found, building repeatable motion |
| Series B | $500k–$2M/month | Scaling GTM with proven unit economics |
| Growth / Series C+ | $2M+/month | Efficient growth with NRR > 110% |
Naive vs corrected
| Version | Formula |
|---|---|
| Naive | Sum of all contract values ÷ 12 (overcounts multi-year prepay and inflates MRR by the full TCV) |
| Corrected | Normalize each contract to its monthly run rate regardless of payment cadence; exclude one-time fees, setup charges, and professional services revenue |
Common errors
- Including professional services or implementation fees in MRR
- Dividing multi-year TCV by 12 instead of normalizing to monthly run rate
- Counting pilots, POCs, or free trials as MRR before contract execution
- Including usage-based overages as base MRR rather than tracking separately
- Not netting out credits and refunds from the MRR figure
Where this sits
Part of the Economics & metrics (C4) cluster in the GTM World Model. Related to the model's "MRR walk identity: MRR_t = MRR_{t-1} + New MRR + Expansion MRR - Contraction MRR - Churned MRR" equation.
