What is SaaS MRR / ARR Calculator?
Monthly Recurring Revenue (MRR) is the predictable monthly income from all active subscriptions. Annual Recurring Revenue (ARR) is MRR × 12 — the standard SaaS top-line metric used by investors and boards. This calculator lets you model multiple pricing tiers simultaneously, account for monthly churn, and instantly see how changes in customer count or pricing affect your revenue trajectory.
How to use this tool
- 1 Edit the default plan names, prices, and customer counts to match your real pricing tiers. Click 'Add Plan' to add up to 8 tiers.
- 2 Set your monthly churn rate — the percentage of customers who cancel each month. Industry benchmarks are 1–3% for B2B SaaS.
- 3 Choose your billing cycle: monthly or annual. Annual prices are automatically divided by 12 to calculate MRR correctly.
- 4 Read your MRR, ARR, ARPU, and churn MRR loss from the summary cards. The plan breakdown table shows revenue concentration across tiers.
- 5 Review the churn impact section — it shows customers lost per month, MRR lost, and net MRR after churn, plus a benchmark insight.
When would you use this?
- Fundraising preparation — investors will ask for MRR, ARR, and churn at every stage. Model these before entering any pitch meeting.
- Pricing decisions — add a new pricing tier and immediately see how even a small number of upgrades shifts overall MRR and ARPU.
- Monthly business reviews — paste in actual plan counts to see a live snapshot of revenue health and churn impact at a glance.
MRR only tells you the revenue side. MonitorGiant monitors the reliability side — uptime, AI performance, and infrastructure health — so your SaaS product earns the MRR you are projecting.
