Enter your monthly recurring revenue and optional details like customer count and contract length to get a full breakdown. Ideal for e-commerce sellers, SaaS companies, and any business with recurring revenue streams.

Annual Recurring Revenue & Related Metrics
How to Use This Tool
Enter your business's Monthly Recurring Revenue (MRR) in the first field. This is the total predictable revenue generated from all active subscriptions each month. Optionally, provide the number of paying customers to calculate Average Revenue Per User (ARPU), and the average contract length in months to determine Total Contract Value (TCV). Select your currency from the dropdown menu. Click "Calculate ARR" to see all metrics. Use "Reset" to clear all fields and start over. The "Copy Results" button appears after calculation for easy sharing.
Formula and Logic
Annual Recurring Revenue (ARR) = MRR × 12. This annualizes your monthly subscription revenue and is the primary metric for subscription business valuation.
Average Revenue Per User (ARPU) = MRR ÷ Number of Customers. Measures revenue efficiency per customer.
Annual Contract Value (ACV) = ARPU × 12. The average yearly value per customer contract.
Total Contract Value (TCV) = MRR × Average Contract Length (months). Represents the total expected revenue from all current contracts over their full term.
Practical Notes
Pricing Strategy: Compare your ARPU against industry benchmarks. B2B SaaS typically sees ARPU of $100-500, while B2C may be lower. If ARPU is below $50, consider product-led growth or tiered pricing. If above $500, ensure your customer success resources scale accordingly.
Margin Thresholds: ARR alone doesn't indicate profitability. Calculate your Gross Margin (Revenue - COGS). Healthy SaaS businesses maintain 70-80% gross margins. If your margin is below 60%, review hosting, support, and payment processing costs.
Trade Terms: For B2B contracts, note that "contract length" often includes initial terms plus automatic renewals. Exclude one-time setup fees from MRR unless they're recurring. For e-commerce subscriptions, include only recurring orders—exclude one-time purchases.
Market Benchmarks: Early-stage startups should target 10-20% quarterly ARR growth. Mature companies (>$10M ARR) typically grow 5-10% quarterly. Use this calculator to model growth scenarios: increasing MRR by 10% while maintaining churn below 5% is a healthy target.
Why This Tool Is Useful
ARR is the lifeblood metric for any subscription business—it's what investors, acquirers, and lenders evaluate. This calculator provides not just ARR but the full suite of related metrics (ARPU, ACV, TCV) in one place, helping you understand revenue composition. For e-commerce sellers transitioning to subscriptions, it clarifies the difference between one-time and recurring revenue. For sales teams, ACV helps prioritize enterprise deals. The insight generator highlights potential issues like low ARPU or short contracts that might affect long-term stability. Use it monthly to track performance and during fundraising to demonstrate business health.
Frequently Asked Questions
Should I include one-time fees in MRR?
No. MRR should only include predictable, recurring revenue. Exclude setup fees, one-time implementation charges, and professional services. Include them in a separate "One-Time Revenue" category. If you have usage-based fees that vary monthly, consider a separate metric like "Monthly Recurring Revenue Plus (MRR+)" that averages those fluctuations.
How does churn affect ARR calculations?
This calculator shows a snapshot of current ARR based on existing customers. To understand growth, you must track Net Revenue Retention (NRR) = (Starting ARR + Expansion MRR - Churned MRR) ÷ Starting ARR. An NRR above 100% means growth from existing customers alone. Use this calculator monthly with churn data to compute NRR. High churn (above 5% monthly) will quickly erode ARR even with new sales.
What's the difference between ACV and ARR?
ARR is total annual recurring revenue from all customers. ACV is the average annual value per customer contract. If you have 100 customers with $100/month plans, ARR = $120,000 and ACV = $1,200. ACV helps compare customer segments—enterprise ACV might be $50,000 while SMB ACV is $1,200. Use ACV to shape pricing tiers and sales compensation. ARR is for overall business health; ACV is for customer-level analysis.
Additional Guidance
For e-commerce sellers: If you have both one-time and subscription sales, calculate "Subscription ARR" separately from total revenue. Track the percentage of revenue from subscriptions—aim for 30%+ as a stability buffer.
For B2B traders: Include only contracted recurring revenue. Exclude project-based work. If you have multi-year contracts, ensure you're annualizing correctly (e.g., a 24-month $1,000/month contract contributes $12,000 to ARR, not $24,000).
Regularly recalculate ARR after major changes: new pricing, churn spikes, or large customer acquisitions. Compare your ARR growth to customer acquisition cost (CAC) payback period—ideally, CAC should be recovered within 12 months. If your ARR is growing but CAC payback extends, investigate sales efficiency.
Finally, ARR is a lagging indicator. Pair it with leading indicators like pipeline value, trial conversion rates, and customer health scores to forecast future ARR more accurately.
