MRR is active subscription revenue normalized to a month. ARR = MRR × 12 expresses that current run rate annually; it is not a forecast or cash collected. Enter ending MRR, and use the revenue movements to explain its change from the previous balance. Net New MRR includes new, expansion, and reactivation revenue, less contraction and churn.
What are MRR and ARR?
Monthly Recurring Revenue (MRR) is active subscription revenue normalized to a month. Annual Recurring Revenue (ARR) is MRR multiplied by 12. These are the foundational metrics for SaaS businesses to track revenue health and growth trajectory.
MRR Formulas
MRR = Sum of all monthly subscription revenue
Net New MRR = New MRR + Expansion MRR + Reactivation MRR - Churned MRR - Contraction MRR
ARR = MRR x 12
Quick Ratio = (New MRR + Expansion MRR + Reactivation MRR) / (Churned MRR + Contraction MRR)
Illustrative MRR growth scenarios
| Scenario | MRR Growth Rate | Quick Ratio |
|---|---|---|
| Faster growth assumption | 10-15% month-over-month | 4:1+ |
| Middle growth assumption | 8-12% month-over-month | 3:1+ |
| Slower growth assumption | 3-5% month-over-month | 2:1+ |
These are illustrative monthly rates and Quick Ratios, not measured benchmarks for funding stages. Compare actual growth using the same period and revenue definition.

Why this matters
Quick Ratio above 1 means new, expansion, and reactivation MRR exceed churn and contraction. NRR above 100% means revenue from the starting customer base grew after expansion and losses.
ARR = CurrentMRR × 12
ARR annualizes your current MRR. The movement breakdown — Net New = (New + Expansion + Reactivation) − (Contraction + Churn) — is diagnostic; see the waterfall. Exclude one-time fees from MRR.
Understanding MRR and ARR: The Foundation of SaaS Business Intelligence
MRR and ARR express subscription revenue on monthly and annual bases. Use them to track recurring revenue, plan scenarios, and explain performance to investors. They normalize the revenue figures; future growth still depends on your assumptions.
The SaaS Metrics Hierarchy: Beyond Basic Revenue
MRR (Monthly Recurring Revenue): Subscription revenue normalized to a monthly amount. Use it for monthly performance tracking and short-term planning.
ARR (Annual Recurring Revenue): MRR multiplied by 12 expresses the current subscription revenue run rate annually. Use it in annual planning, valuations, and investor discussions.
Advanced Metrics: Review NRR, GRR, Quick Ratio, and ARPU alongside total revenue to examine retention, expansion, and revenue per customer.
When to use MRR and ARR
Use MRR when: Use MRR for monthly forecasting and short-term performance tracking. Compare changes over time to examine trends and seasonal patterns.
Use ARR when: Use ARR when discussing annual strategy, communicating with investors, or comparing subscription businesses on an annual basis.
Track Both: Use MRR for monthly operational reviews and ARR for an annual view in dashboards and investor updates.
Critical SaaS Revenue Health Indicators
- Net Revenue Retention (NRR): Starting revenue retained after expansion, contraction, and churn; above 100% means the starting customer base grew in revenue
- Gross Revenue Retention (GRR): Starting revenue retained after contraction and churn, excluding expansion
- Quick Ratio: (New MRR + Expansion MRR + Reactivation MRR) / (Churned MRR + Contraction MRR) in this calculator
- ARPU (Average Revenue Per User): MRR divided by current paying customers
- MRR Growth Rate: Month-over-month percentage growth - should align with business stage and market conditions
Common MRR/ARR Calculation Mistakes
Teams frequently struggle with: 1) Including one-time fees in recurring revenue calculations, 2) Inconsistent treatment of annual vs monthly subscriptions when normalizing, 3) Confusing gross revenue with net revenue (ignoring refunds and adjustments), 4) Not properly segmenting new vs expansion vs churned revenue components, and 5) Mixing recognized revenue with contracted revenue in financial reporting.
Advanced Revenue Segmentation Strategies
New vs Expansion vs Churn: Break MRR changes into new, expansion, and churned revenue. These components show where revenue was added or lost; investigate the underlying causes separately.
Cohort Analysis: Track MRR evolution by customer acquisition cohorts to understand long-term value trends and identify optimal customer segments for growth investment and retention focus.
Geographic and Product Segmentation: Analyze MRR by region, product line, or customer segment to identify growth opportunities and potential risks in specific market areas or product categories.
Benchmarking Your MRR/ARR Performance
SaaS Capital's 2025 surveyreported 25% median annual growth for private B2B SaaS companies in 2024. That is an annual sample median, not a monthly target. Compare businesses of similar size and business model; the calculator's color bands are fixed model references.
Strategic Applications: From Metrics to Decisions
Use MRR and ARR analysis when reviewing pricing and ARPU, customer success and NRR, expansion opportunities, new MRR sales targets, and ARR growth in fundraising plans. Discuss the assumptions with the teams responsible for those decisions.
What is Monthly Recurring Revenue (MRR)?
Monthly Recurring Revenue (MRR) is active subscription revenue normalized to a month. New subscriptions, expansion, and reactivation add MRR; cancellations and downgrades reduce it. ARR is MRR multiplied by 12.
Net New MRR Formula
Net New MRR = New + Expansion + Reactivation - Churn - Contraction MRR
Annual growth comparison
Median 2024 annual revenue growth was 25% in SaaS Capital’s Q1 2025 survey of over 1,000 private B2B SaaS companies.

Common questions
What is the difference between MRR and ARR?
MRR is recurring subscription revenue expressed as a monthly amount. ARR is that current run rate multiplied by 12, not a forecast of revenue actually earned over the next year. Use monthly figures to inspect revenue movements and annualized figures to compare scale.
How do you calculate MRR correctly?
Add recurring subscription charges after converting them to monthly amounts. Divide an annual subscription by 12 and exclude one-time fees. For example, 100 customers paying $50 per month produce $5,000 MRR. Enter normalized monthly revenue per customer in this calculator.
What is a good Net Revenue Retention (NRR) rate?
NRR above 100% means expansion exceeded contraction and churn for the measured customer base. SaaS Capital’s April 2026 release reported 103% median NRR for bootstrapped SaaS companies with $3–20M ARR. Use that figure only for a comparable cohort and reporting period.
How do I calculate Quick Ratio for SaaS?
The SaaS quick ratio compares recurring revenue gains with churn and contraction losses. This calculator includes new, expansion, and reactivation MRR in gains. A ratio above 1 means gains exceed losses. If losses are zero, there is no finite ratio; review the actual revenue movements alongside any reference band.
What MRR growth rate should a SaaS startup target?
Set a target using your current revenue base, acquisition capacity, retention, and funding constraints. Compare sourced benchmarks only when company size and measurement period match. A monthly growth rate and an annual growth rate are not interchangeable; do not treat the calculator’s fixed bands as observed SaaS medians.
What is the difference between GRR and NRR?
Gross Revenue Retention (GRR) measures pure retention without expansion, capped at 100%. Net Revenue Retention (NRR) includes expansion revenue and can exceed 100%. GRR shows retention health, while NRR shows overall customer revenue growth potential.
