## MRR & ARR calculator

Enter your customers, average revenue per account, and net monthly growth. Get your MRR and ARR now — and where they land 12 months from now.

The short answer MRR is **customers × ARPA**; ARR is **MRR × 12**. 120 customers at $80/mo is **$9,600 MRR** ($115,200 ARR) — and at 8%/mo net growth it compounds to about **$24,174 MRR** within a year. Paying customers Average revenue per account (ARPA) / mo Net monthly growth 8%

Net growth = new + expansion − churned, per month. For churn, lifetime, and LTV, use the [churn calculator](https://aioproductos.com/tools/churn-rate-calculator).

Beyond the number

### MRR is the metric — the why behind it is what moves it.

**Revenue per account, not per spreadsheet.** When each customer's MRR lives on their record, you can rank feedback and roadmap by the money behind it — not vote count.

**Growth has a cause.** Net growth nets out churn. Pair this with the churn calculator to see how much of your curve is leaking out the bottom.

**Projections age fast.** A static model is stale the day a deal closes. On a connected spine, MRR updates from your billing connector instead of a quarterly rebuild.

FAQ

### MRR & ARR questions

**What is MRR and how is it calculated?**

MRR (monthly recurring revenue) is the predictable subscription revenue your customers pay each month. The simplest formula is customers × average revenue per account (ARPA). For example, 120 customers at $80/mo is $9,600 MRR.

**How do I calculate ARR from MRR?**

ARR (annual recurring revenue) is simply MRR × 12. It annualizes your current monthly run rate — it does not add growth. To project forward, grow MRR each month first, then annualize the later figure.

**What is a good monthly growth rate for MRR?**

It depends on stage. Early-stage SaaS often targets 5–15% net monthly MRR growth; that compounds fast — a steady rate roughly triples MRR over a year. Net growth already accounts for churn, so watch it alongside your churn rate.

**Does this calculator account for churn?**

The growth input is your NET monthly growth — new and expansion revenue minus churned revenue. To model churn explicitly (retention, lifetime, LTV), use the churn-rate calculator linked below.

## Why AIOProductOS

- **One MCP over the whole product spine, not one tool.** 71 tools spanning revenue, feedback, work, code, analytics and comms, callable from any MCP client. Competing MCP servers expose a single product's own data; this one answers across the join, and it is listed on the official MCP registry.
- **Connected, not consolidated.** 118 connectors land Stripe, GitHub, your feedback tool and the rest onto one shared record, so a product question is a join instead of a reconciliation. You keep the tools you already run.
- **Flat plans, not a per-head meter.** Member counts are allowances, not per-seat billing, and AI teammates are included rather than metered per credit. Compare the real number for your team with the [stack cost calculator](https://aioproductos.com/tools/saas-stack-cost-calculator).
- **Nothing is plan-gated.** Every tier ships every module. The only limits are seats and agents, so the cheapest plan is the whole product.
- **Your data stays yours.** EU or US residency chosen at signup, bring your own model key, full-org GDPR export on every tier, and we never train on your data.
- **Honest onboarding.** A 14-day runway on your own data, then a 30-day money-back guarantee. No stripped free tier and no countdown trial with a meter running.
