Everything you need to know about SaaS MRR
What is MRR?
Monthly Recurring Revenue normalizes all your subscription revenue — monthly, annual, or otherwise billed — into a consistent monthly figure, which is the standard way SaaS businesses track predictable revenue and growth over time.
When you actually need this
- Tracking growth month over month in a way that's comparable regardless of billing cycle mix.
- Reporting to investors or stakeholders, who typically expect MRR/ARR as the standard SaaS metric.
MRR vs. ARR
ARR (Annual Recurring Revenue) is simply MRR × 12 — the same underlying number expressed on an annual basis, more commonly used for larger contracts or higher-level reporting.

Frequently Asked Questions
How is ARR calculated from MRR?
Simply MRR × 12 — it assumes current MRR holds steady for a year, which is the standard convention, not a growth forecast.
What does "net new MRR" tell me?
New MRR added this month minus MRR lost to churn. A positive number means you grew; a negative number means churn outpaced new business, even if your total MRR still looks healthy.
Can I enter more than one pricing plan?
Yes — add a row for each plan tier with its price and customer count, and the calculator sums all of them into your total MRR.
