MRR & ARR Growth Calculator
Project your recurring revenue forward. Enter current MRR, new MRR and churn to see where MRR and ARR land in a year.
Example: with Current MRR $50,000 · New MRR added / month $6,000 · Monthly churn rate 4% · Project forward 12 months → Projected MRR: $88,729.
- Projected ARR$1,064,748
- Net new MRR (current month)$4,000 / mo
- Monthly churn4.0%

Net new MRR each month is new revenue minus churned revenue. Because churn scales with your base, growth slows as you get bigger unless new sales keep pace — which is why reducing churn is so valuable at scale. ARR is simply MRR × 12.
How it’s calculated & sources
Each month we add new MRR and subtract churned MRR (current MRR × churn rate), iterating forward over the months you choose. ARR = projected MRR × 12.
Benchmark: ARR = MRR × 12; strong SaaS keeps net revenue retention above 100% so the base grows even before new sales.

Frequently asked questions
What counts as MRR?
Only predictable, recurring subscription revenue — normalize annual plans to a monthly figure and exclude one-time fees.
Why does growth slow over time?
Churn is a percentage of a growing base, so absolute churn rises as MRR grows. Sustained growth needs rising new MRR or falling churn.
