Introduction
In the subscription-based SaaS (Software as a Service) industry, understanding revenue metrics is crucial for monitoring growth, forecasting, and making strategic decisions. Two of the most important metrics are Monthly Recurring Revenue (MRR) and Annual Recurring Revenue (ARR). However, there are alternative revenue metrics and variations that companies may consider depending on their business model and reporting needs.
This guide provides a comprehensive comparison between MRR, ARR, and their primary alternatives, highlighting their pros, cons, and ideal use cases.
Key Revenue Metrics in SaaS
| Metric | Definition | Calculation Example | Common Use Case |
|---|---|---|---|
| MRR (Monthly Recurring Revenue) | Recurring revenue normalized on a monthly basis. | Sum of all active customers' monthly fees | Short-term revenue tracking, growth monitoring |
| ARR (Annual Recurring Revenue) | Recurring revenue normalized on an annual basis. | MRR × 12 | Long-term forecasting, valuation assessments |
| Bookings | Total value of all new contracts signed in a period (may include one-time fees). | Sum of contract amounts signed | Sales performance and pipeline analysis |
| Cash Receipts | Actual cash collected in a period, including renewals, upgrades, and one-time fees. | Total cash received | Cash flow management |
| Committed Monthly Recurring Revenue (CMRR) | MRR including signed contracts not yet active, minus churned revenue. | Starting MRR + New MRR - Churned MRR | Forward-looking revenue visibility |
Detailed Comparison Table
| Feature/Metric | MRR | ARR | Bookings | Cash Receipts | CMRR |
|---|---|---|---|---|---|
| Measurement Period | Monthly | Annual | Contract signing period | Payment receipt period | Monthly (includes future contracts) |
| Revenue Type | Recurring only | Recurring only | Recurring + One-time fees | All cash received (recurring & one-time) | Recurring + signed but not started contracts |
| Volatility | Higher, sensitive to short-term changes | Smoother, less reactive to monthly fluctuations | Variable, depends on sales cycle | Can be irregular (payment timing issues) | Smoothed, includes forward-looking contracts |
| Best For | Monitoring short-term growth and churn | Annual financial forecasting and valuation | Sales pipeline and contract management | Cash flow analysis and operational planning | Predicting near-term revenue changes |
| Cons | May overemphasize short-term fluctuations | Less granular, slower to reflect changes | May include non-recurring revenue skewing view | Doesn't reflect revenue earned, just cash received | Complexity in calculation and assumptions needed |
