ARR Calculator

Summary

ARR (Annual Recurring Revenue) is the backbone metric for any subscription or SaaS business. This calculator lets you convert Monthly Recurring Revenue (MRR) to ARR in one click, or build up ARR from individual subscription tiers with different plan counts and prices. It also computes ARPU, projects ARR after a given growth rate, and shows how churn erodes your revenue.

How it works

1. Choose the MRR mode to enter a single MRR figure, or switch to Subscription mode to add multiple plans.
2. In MRR mode, type your current Monthly Recurring Revenue — ARR is MRR × 12.
3. In Subscription mode, add each plan with its price and number of active subscribers.
4. Optionally enter a monthly growth rate and churn rate to project future ARR.
5. Results update in real time: ARR, MRR, ARPU, projected ARR, and net ARR after churn.

Use cases

• Quickly convert MRR to ARR for investor decks and board reports.
• Model ARR across multiple pricing tiers before a pricing change.
• Estimate projected ARR after a growth or expansion hire.
• Understand how churn rate shrinks your annual revenue.
• Benchmark ARPU across subscription cohorts.

• Validate ARR targets against current subscriber counts.
