MoM vs YoY Growth
- MoM shows short-term momentum — great for operational decisions and tracking experiments
- YoY shows long-term trajectory — better for strategic planning and removes seasonal noise
- Annualized MoM compounds monthly growth to show what it equals yearly — useful for projections, but assumes sustained growth
- Paul Graham's rule: startups should target 5-7% weekly growth. In MoM terms, that's roughly 20-30% monthly
- Most SaaS companies see MoM growth slow as they scale — 15% at $100K ARR, 5% at $1M, 2-3% at $10M is typical
About this tool
Month-over-month growth is the pulse of your business. It's the metric you check every first-of-the-month to know if things are heading in the right direction. Unlike annual reviews, MoM gives you fast feedback — so you can double down on what's working or course-correct before a small dip becomes a big problem.
This calculator gives you more than a percentage. The trend mode tracks multiple months to detect whether your growth is accelerating, decelerating, or volatile. It annualizes your MoM rate so you can see what sustained monthly growth actually means over a year (spoiler: it compounds fast — 5% MoM is 80% annualized).
For email marketing, MoM growth of your subscriber list tells you a lot about your acquisition engine. Are your signup forms converting? Are you losing subscribers faster than you're gaining them? Track list growth alongside unsubscribe rate and net list growth for the complete picture.
For bigger-picture analysis, switch to our year-over-year growth calculator which removes seasonal noise, or use the MRR calculator to track revenue growth specifically.
