ARR vs MRR: Complete Comparison Guide
Understand the key differences between Annual Recurring Revenue and Monthly Recurring Revenue, when to use each metric, and why both matter for your SaaS business.
Quick Overview
ARR
Annual Recurring Revenue
- ✓ Long-term strategic view
- ✓ Investor & board reporting
- ✓ Annual planning & forecasting

The Relationship Between ARR and MRR
ARR and MRR are two sides of the same coin. They measure the same thing—recurring revenue—but on different time scales:
Example: If your SaaS business has $100,000 in MRR, your ARR is $1,200,000. This means you're generating $100K monthly or $1.2M annually in predictable, recurring revenue.
Detailed Comparison
| Aspect | ARR | MRR |
|---|---|---|
| Time Frame | Annual (12 months) | Monthly (1 month) |
| Primary Use | Strategic planning, investor reporting | Operational management, daily decisions |
| Reporting Frequency | Quarterly or annually | Monthly or weekly |
| Volatility | Lower (smoothed over time) | Higher (shows monthly fluctuations) |
| Best For | Big picture, fundraising, valuation | Growth tracking, cash flow, operations |
| Typical Threshold | $1M+ (for external reporting) | Pre-$1M ARR startups |
| Calculation | Sum of annual contract values | Sum of monthly subscriptions |
| Investor Preference | Series A+ preferred metric | Seed stage preferred metric |
When to Use Each Metric
Use ARR When:
- →Presenting to investors or board members
- →Discussing company valuation (multiples are based on ARR)
- →Planning annual budgets and hiring
- →Comparing to industry benchmarks (most reported as ARR)
- →Setting long-term growth targets
- →Your company is past $1M in annual recurring revenue
Use MRR When:
- →Managing day-to-day operations and tactics
- →Tracking monthly growth rate and momentum
- →Forecasting short-term cash flow
- →Analyzing impact of recent changes quickly
- →Setting monthly team targets and OKRs
- →You're in early stages (pre-$1M ARR)
💡 Pro Tip:
Most successful SaaS companies track both metrics internally but choose one for external communication based on their stage. Early-stage companies (<$1M ARR) typically emphasize MRR growth, while later-stage companies focus on ARR for investor relations.
Understanding MRR Movements
Both ARR and MRR can be broken down into movement components that help you understand what's driving growth or contraction:

📉 Negative Movements
Real-World Examples
Example 1: Early-Stage Startup (MRR Focus)
Company: TaskFlow (project management SaaS)
Stage: Seed, 8 months post-launch
Current MRR: $42,000 (~$504K ARR)
Why they track MRR:
- Monthly growth rate is 15-20%, making month-to-month changes significant
- Need to quickly identify what marketing channels are working
- Cash flow is tight, so monthly recurring revenue matters for operations
- When talking to seed investors, "$42K MRR growing 18% MoM" is more impressive than "$504K ARR"
Example 2: Growth-Stage Company (ARR Focus)
Company: DataSync (data integration platform)
Stage: Series B, 4 years old
Current ARR: $24M (~$2M MRR)
Why they track ARR:
- At scale, monthly fluctuations are noise; annual trends matter
- Board meetings focus on annual targets and strategic milestones ($25M, $50M, $100M ARR)
- Valuation discussions use ARR multiples (typically 5-15x ARR for growth SaaS)
- Industry comparisons and benchmarks are reported in ARR
- Enterprise contracts are typically annual, making ARR more natural
Common Mistakes to Avoid
❌ Mistake #1: Mixing One-Time and Recurring Revenue
Wrong: Including setup fees, consulting, or one-time purchases in ARR/MRR
Right: Only count recurring subscription revenue. Track one-time revenue separately as "Non-Recurring Revenue"
❌ Mistake #2: Confusing Cash with MRR
Wrong: Recording a $12K annual contract as $12K MRR because you received the payment
Right: That contract is $1K MRR ($12K ÷ 12 months) and $12K ARR, regardless of payment timing
❌ Mistake #3: Switching Metrics Mid-Conversation
Wrong: "We're at $500K ARR with 10% monthly growth"
Right: "We're at $500K ARR with 120% annual growth" OR "We're at $42K MRR with 10% monthly growth"
❌ Mistake #4: Ignoring Movement Components
Wrong: Only tracking total ARR/MRR without understanding what's driving changes
Right: Break down into New, Expansion, Contraction, and Churned MRR to understand growth dynamics
Frequently Asked Questions
What is the main difference between ARR and MRR?
ARR (Annual Recurring Revenue) shows the annualized value of your recurring revenue, while MRR (Monthly Recurring Revenue) shows the monthly value. ARR is calculated as MRR × 12, and is typically used for strategic planning and investor reporting, while MRR is used for operational tracking and short-term decision making.
Should I track ARR or MRR for my SaaS startup?
Track both. MRR is essential for day-to-day operations, cash flow management, and detecting trends quickly. ARR is crucial for investor conversations, long-term planning, and understanding your annual business scale. Most successful SaaS companies report ARR publicly but manage MRR internally.
At what stage should I switch from MRR to ARR reporting?
Most SaaS companies transition to ARR as their primary external metric around $1M ARR (approximately $83K MRR). Below this threshold, monthly fluctuations matter more, so MRR is more meaningful. However, continue tracking both metrics internally regardless of which you report externally.
How do annual contracts affect ARR vs MRR?
Annual contracts paid upfront still count as MRR (contract value ÷ 12) and ARR (full contract value). The key is to measure recurring revenue, not cash received. A $12,000 annual contract contributes $1,000 to MRR and $12,000 to ARR, regardless of payment timing.
Can I have high ARR but negative cash flow?
Yes, absolutely. ARR measures committed recurring revenue, not cash in the bank. You can have $10M ARR but be burning $1M/month if your expenses exceed revenue. This is why successful SaaS companies track ARR/MRR and burn rate and runway—they measure different aspects of business health.
