Monthly Recurring Revenue (MRR)
Monthly Recurring Revenue (MRR) is the normalised monthly revenue from a subscription business - all active contracts, annualised and divided by twelve, summed together. MRR is the primary health metric for SaaS and subscription companies because it makes revenue predictable and comparable across customers, plans, and time periods. A company’s MRR chart is usually the first thing investors, operators, and boards look at when evaluating SaaS business performance.
How MRR is calculated
Two standard approaches:
Sum of monthly-equivalent contract values. For each active contract: (annual contract value) ÷ 12. Monthly contracts count at their monthly price. Annual contracts get prorated.
Contracted revenue approach. Same idea, but computed at contract signing rather than through payment collection. Shows ‘signed MRR’ even before first payment.
Both approaches produce similar results for steady-state; they can diverge during growth periods as new contracts sign before revenue recognises.
MRR components
Five pieces that roll up to total MRR:
New MRR. MRR from newly-acquired customers in the period. Primary growth indicator.
Expansion MRR. Additional MRR from existing customers upgrading, adding seats, or buying add-ons. Highest-margin revenue growth.
Contraction MRR. Lost MRR from existing customers downgrading or reducing seats. Different from churn (customer still active, just smaller).
Churned MRR. MRR lost to fully-cancelled customers.
Reactivation MRR. Previously-churned customers who return.
Net new MRR = New + Expansion + Reactivation − Contraction − Churned. Tracks whether the business is growing.
MRR growth rate
Industry benchmarks for 2026:
Early-stage SaaS (under $1M ARR). 15–20% monthly growth reasonable; top performers exceed 30%.
Growth-stage SaaS ($1M–$10M ARR). 8–15% monthly; top performers exceed 20%.
Scale-stage SaaS ($10M+ ARR). 3–8% monthly (typically expressed as 100%+ year-over-year at $10M, tapering as the base grows).
Growth rates are base-dependent. A 50% monthly growth rate at $100K MRR isn’t comparable to 5% at $10M MRR, even though the absolute MRR addition is larger at the higher base.
Why MRR matters
Four operational uses:
Predictable revenue. MRR, unlike project revenue, is roughly predictable month-to-month. Financial planning becomes tractable.
Valuation anchor. SaaS valuations are typically expressed as multiples of ARR (MRR × 12). Growing MRR directly grows enterprise value at the valuation multiple.
Compensation and incentives. Sales commissions, product-team goals, board targets are often MRR-based. The metric becomes the operational language.
Segmentation and analysis. MRR by segment, plan, or cohort reveals where the business is growing or shrinking. Aggregate MRR hides these patterns.
MRR measurement mistakes
Four common errors:
Including one-time revenue. Setup fees, professional services, training - these aren’t recurring and shouldn’t count toward MRR.
Inflating annual contracts. Signing a $120K annual contract doesn’t add $120K to MRR; it adds $10K. Basic but often missed.
Ignoring currency fluctuation. International MRR reported in home currency moves with exchange rates. A 3% MRR drop might be pure FX, not churn.
Including trial revenue. MRR should reflect paying customers, not trials or free users. Some companies count converted-to-paid as MRR only from the payment date.
MRR vs ARR
Simple relationship:
MRR. Monthly normalisation. Tracks month-over-month movement.
ARR. MRR × 12. Annual-run-rate expression. Investors and boards often prefer ARR because it’s annual-scale.
The two are the same underlying number. Convention is to use MRR for monthly tracking and ARR for quarterly/annual reporting.
MRR in content-strategy decisions
Three ways MRR thinking shapes content:
Content ROI measurement in MRR. ‘This content programme drove $50K in new MRR’ is more executively legible than ‘47,000 visits.’ MRR attribution makes content accountability clearer.
Retention content prioritisation. Content that reduces churn directly preserves MRR. Retention-focused content gets more obviously valuable when measured in MRR terms.
Expansion-content value. Content that drives upgrades, seat expansions, or feature adoption produces expansion MRR. Usually under-measured because the attribution is messy; worth modelling anyway.
We built Penfriend partly because content programmes in SaaS businesses often under-invest in expansion and retention content even though those content types have more direct MRR impact than acquisition content. Production economics push toward acquisition content because it’s the biggest, not the highest-ROI. Penfriend makes the full MRR-impacting content stack economically defensible.
