MRR

MRR (Monthly Recurring Revenue) is the predictable revenue a subscription business expects to collect every month from its active customer base. It strips out one-time payments, professional services, and usage spikes to isolate the recurring core of the business — the number investors, founders, and finance teams watch most closely to judge a SaaS company's health and growth trajectory.

MRR matters because it converts lumpy, unpredictable cash inflows into a normalised, comparable metric. A customer paying $1,200 once a year and a customer paying $100 every month contribute the same $100 to MRR, making it possible to compare revenue health across customers on different billing cycles.

MRR = Sum of (Monthly Price × Active Customers) across all plans and tiers

MRR = Total Annual Contract Value / 12 (for customers billed annually)

ARR = MRR × 12

Net New MRR = New MRR + Expansion MRR − Churned MRR − Contraction MRR

A SaaS company has three pricing tiers:

ARR = $9,355 × 12 = $112,260

If monthly churn is 3%, projected next-month MRR after losing churned customers:

Projected MRR = $9,355 × (1 − 0.03) = $9,074.35

Use the MRR / ARR calculator to model this across your own pricing tiers and churn assumptions.

• MRR is a snapshot, not a forecast: MRR tells you what you're collecting right now, not what you'll collect next month. Combine it with churn rate to project forward — a company with high MRR but high churn can shrink quickly despite looking healthy on paper.
• Watch the composition, not just the total: Two companies can have identical $50,000 MRR, but one driven by 500 small accounts and another by 5 large enterprise accounts have very different risk profiles — concentration risk matters as much as the headline number.
• MRR feeds directly into valuation: SaaS companies are commonly valued as a multiple of ARR (often 3-10× depending on growth rate, margins, and market conditions). Small swings in MRR growth rate can materially change a company's valuation multiple, which is why investors scrutinise MRR trends closely during fundraising.
• Burn rate context matters: A company's burn rate relative to its MRR determines runway and the urgency of reaching profitability or raising more capital — MRR growth alone doesn't guarantee survival if costs are growing faster.
• Cohort-level MRR reveals retention quality: Tracking MRR by customer signup cohort (e.g., all customers who joined in January) shows how revenue from a given group evolves over time — expanding, flat, or shrinking — which is a much sharper signal of product-market fit than aggregate MRR alone.
