Monthly revenue growth rate is the most important number for an early-stage SaaS company. It compounds rapidly — 10% MoM means ~214% annualised growth. Getting clarity on what "good" looks like helps you avoid two common mistakes: celebrating modest growth as exceptional, or burning yourself out chasing an unrealistic target.
MoM growth benchmarks by stage
| ARR Stage | Excellent MoM | Solid MoM | Concerning |
|---|---|---|---|
| $0–$1M | 20–30%+ | 10–20% | < 5% |
| $1M–$5M | 15–20% | 8–15% | < 5% |
| $5M–$20M | 8–15% | 5–10% | < 3% |
| $20M+ | 5–8% | 3–5% | < 2% |
Growth rates naturally decline as ARR grows — it's harder to double $20M ARR than $200k ARR. The question is whether your growth is decelerating faster than expected.
The compounding reality
5% MoM = 80% YoY. 10% MoM = 214% YoY. 15% MoM = 435% YoY.
These numbers look beautiful in a spreadsheet and brutal when you're behind target. Use the Revenue Growth Rate Calculator to see what your current MoM rate means for your annual trajectory and doubling time.
