A negative CMGR of 0.0% means revenue is contracting. Churn reduction is the highest-leverage move: even getting to flat growth unlocks compounding again.

The calculator has two modes. Use Calculate My CMGR to find your historical growth rate. Use Project Future Growth to model a scenario and see where a target rate takes you.
Enter your Starting Value
Input your MRR, revenue, users, or any metric at the beginning of your measurement period. This is month zero.
Enter your Ending Value
Input the same metric at the end of your period. It can be lower than your starting value — the calculator handles negative CMGR.
Set the Number of Months
Enter the number of months between your two data points. Use 12 for a full year, 6 for half-year, 3 for a quarter.
Read your results
Your CMGR, CAGR equivalent, months-to-double, and performance tier update instantly. The chart shows the full compounding curve.
Enter your Current Value
Input today's MRR or metric. This is your starting point for the forward projection.
Set your Target CMGR
Enter the monthly growth rate you want to model. Try 10% for a realistic stretch goal, or 20% to see what world-class growth looks like from your current base.
Choose a Projection Period
Select how far out to project — 12 months for a near-term forecast, 24–36 months for a strategic plan.
Use the outputs in your planning
The projected end value and CAGR tell you exactly what this growth rate means in dollar terms. Paste the number into your board deck or fundraising model.
CMGR %
Your compounded monthly rate. This is the headline number to share with investors and track over time.
Annualized (CAGR)
The true yearly equivalent of your CMGR. Use this when comparing to annual benchmarks or public company growth rates.
Months to Double
How long until your metric is 2× its current value at this CMGR. Calculated via log(2) / log(1 + CMGR).
Monthly Multiplier
The exact factor applied each month (e.g., 1.1000× at 10% CMGR). Useful for manual projections in a spreadsheet.
Performance Tier
Your CMGR ranked against SaaS industry benchmarks from Early-Stage through World-Class.
Growth Trajectory
The area chart shows the compounding curve — visually demonstrating why exponential growth looks slow at first, then explosive.
Most teams track CMGR wrong, or not at all. Here is a practical setup you can implement this week.
Choose a single north-star metric to track CMGR on. For most SaaS companies this is MRR. For PLG companies it may be active seats or weekly active users. Pick one and stick to it so month-over-month comparisons are meaningful.
Consistency matters more than precision. Record your metric on the 1st of each month (or last day — either works, just never alternate). Even a simple Google Sheet column with date + value is enough to start.
A single month's CMGR is noisy. Track a 3-month CMGR (current vs 3 months ago, n=3) and a 6-month CMGR (n=6) side by side. If 3-month CMGR is falling toward 6-month CMGR, growth is decelerating — act before it shows in ARR.
Most founders track total MRR but not CMGR. Adding it to a weekly metrics email or Slack post creates accountability and surfaces deceleration 4–8 weeks earlier than watching the absolute MRR number alone.
Revenue targets in absolute dollars get harder to hit at scale. A CMGR floor (e.g., "we will not let CMGR drop below 8%") scales automatically with your base, keeps the team focused on rate not just volume, and is the metric investors will ask about anyway.
Paste your start MRR, current MRR, and month count into the "Calculate My CMGR" tab before every board meeting or investor update. The CAGR equivalent output translates your monthly progress into the annualized language institutional investors are most comfortable with.
Both measure compounding growth — but they serve different purposes and time horizons.
| Dimension | CMGR | CAGR |
|---|---|---|
| Period | Month-over-month | Year-over-year |
| Best for | SaaS, startups, short-term KPIs | Long-term investments, M&A analysis |
| Formula | (End ÷ Start)^(1/n) − 1 | (End ÷ Start)^(1/years) − 1 |
| Conversion | CMGR → CAGR: (1 + CMGR)^12 − 1 | CAGR → CMGR: (1 + CAGR)^(1/12) − 1 |
| 10% example | 10% CMGR = 214% CAGR | 10% CAGR = 0.8% CMGR |
| Used by | Founders, SaaS VCs, growth teams | Public equity analysts, PE firms |
The most common mistake founders make: multiplying CMGR by 12. That gives you a simple annual rate — not the compounded one. Here is the correct conversion, both ways.
Step 1. Add 1 to your CMGR decimal (e.g., 10% → 1.10)
Step 2. Raise to the power of 12 (one full year of months)
Step 3. Subtract 1 and multiply by 100 for the percentage
Note: 10% × 12 = 120% is wrong — compounding adds an extra 93.8 percentage points.
Step 1. Add 1 to your CAGR decimal (e.g., 200% → 3.00)
Step 2. Take the 12th root (raise to the power of 1/12)
Step 3. Subtract 1 and multiply by 100 for the percentage
Use this when comparing to public market benchmarks quoted as annual returns.

"Naive ×12" column shows why multiplying CMGR by 12 always understates true annual growth — the compounding effect grows larger as CMGR increases.
CAGR (Compound Annual Growth Rate) smooths volatile year-over-year returns into a single annualized rate. Here is the formula, a worked example, and the Excel shortcuts.
What $10,000 becomes in 10 years
Each bar is proportional to the 30% scenario max. Note how the gap between 10% and 30% widens every year — that is compounding at work.
Investment grew from $100,000 → $200,000 over 7 years:
Standard formula
A2 = start value, B2 = end value, C2 = years
RRI function (shortcut)
Excel's built-in CAGR function — fewer cells needed.
CMGR to CAGR in Excel
A2 = CMGR as a decimal (e.g., 0.10 for 10%)
Both measure compounding growth — but context dictates which one actually tells the right story.
Short-term, high-velocity growth
Long-term, multi-year perspective
Founder tip: Always state which metric you are quoting. A 10% CMGR sounds modest but equals 214% CAGR — nearly 3× growth in a year. Institutional investors think in CAGR; operators think in CMGR. Translating between them shows financial fluency and builds trust in the room.
CMGR (Compound Monthly Growth Rate) is the rate at which a metric grows each month, assuming that growth compounds. It is the single number that normalizes growth velocity across any time period and makes it easy to compare companies and cohorts fairly.
Unlike simple MoM averages, CMGR accounts for the exponential nature of compounding — making it the metric VCs most often use to evaluate early-stage SaaS companies. A business with 10% CMGR triples in 12 months. That story is impossible to tell with a simple average.
