MRR
Monthly Recurring Revenue (MRR) is the amount of revenue a subscription business expects to collect every month. Only recurring subscription income counts — one-time fees, setup charges, refunds, and credits are excluded. It's the single most important growth metric in subscription SaaS, media, and commerce.

Why It Matters
Most SaaS valuations derive from ARR (MRR × 12) and growth rate. KeyBanc's 2025 SaaS Survey shows top-quartile SaaS companies grow MRR 80%+ year over year. MRR is the shared language of founders, boards, and growth teams because it shows predictable future cash flow — not a one-shot deal. For inbound marketing, MRR is the ultimate check on whether your blog is producing actual revenue, not just traffic.
How to Calculate
Basic formula: MRR = paying customers × average monthly revenue per customer
Example: 100 customers on a $120/year plan → $10/month × 100 = $1,000 MRR
Always normalize annual upfront payments to a monthly basis. Exclude taxes, one-time setup fees, refunds, and credits.
MRR Sub-Metrics
New MRR: Revenue from new paying customers this month
Expansion MRR: Increases from upgrades and added seats on existing accounts
Reactivation MRR: Revenue recovered from churned customers who came back
Churned MRR: Revenue lost from cancellations
Contraction MRR: Revenue lost from downgrades
Net New MRR = New + Expansion + Reactivation − Churned − Contraction
Tracking these components shows whether growth comes from new acquisition, existing-customer expansion, or is leaking through churn.
How MRR Relates to Other Metrics
MRR × 12 = ARR (Annual Recurring Revenue): The metric leadership and investors usually watch.
CAC Payback = CAC / MRR: How many months of MRR to recover CAC. Under 12 months is healthy.
Net Dollar Retention (NDR): (Starting MRR + Expansion − Churn − Contraction) / Starting MRR × 100. Over 120% means expansion outpaces churn.
Rule of 40: MRR growth rate + operating margin ≥ 40. A maturity check for SaaS.
How to Grow MRR
Acquire more customers: Inbound content, SEO, and paid media drive top-of-funnel.
Expansion plays: Usage-based pricing, added seats, premium feature upsell, contract upgrades.
Reduce churn: Better onboarding, customer success programs, value re-activation campaigns.
Price redesign: Pricing aligned to the value unit (users, messages, files) creates natural expansion.
Common Pitfalls
Don't mix one-time revenue into MRR: Setup fees, consulting, and events aren't recurring.
Don't ignore refunds and credits: Including money you won't actually collect distorts the number.
Watch fee models: Payment processing fees and platform cuts should be handled separately or excluded.
