How to Use the Calculator – Step-by-Step

- Rolling Average 1
- Rolling Average 2
Review Results – Instantly see both rolling averages and the percentage change between them.

Interpret Growth – The calculator tells you whether growth is accelerating (positive trend) or slowing (negative trend).

Understanding Results

After calculation, you’ll see three key outputs:

Rolling Average 1: Represents the average performance over the first three months.
Rolling Average 2: Represents the average performance over the latest three months.
Rolling Growth %: Indicates the relative change between both rolling averages.

Industry Benchmarks

Industry	Typical 3-Month Rolling Growth	Interpretation
SaaS / Tech	+6% to +15%	Healthy acceleration
Fintech	+5% to +12%	Solid growth momentum
E-commerce	+3% to +10%	Moderate seasonal variation
Content / Media	+2% to +8%	Steady audience expansion
Retail / Offline	0% to +5%	Stable baseline

Values vary based on competitiveness, market size, and customer acquisition goals.

Practical Example

Example Data:
M1 = ₹10,00,000 | M2 = ₹11,00,000 | M3 = ₹12,00,000 | M4 = ₹13,50,000

Step 1:
Rolling Average 1 = (10,00,000 + 11,00,000 + 12,00,000) ÷ 3 = ₹11,00,000

Step 2:
Rolling Average 2 = (11,00,000 + 12,00,000 + 13,50,000) ÷ 3 = ₹12,16,667

Step 3:
Rolling Growth % = ((12,16,667 – 11,00,000) ÷ 11,00,000) × 100 = +10.6%

Interpretation:
Growth is accelerating by 10.6% — a strong, sustained upward trend indicating consistent performance improvements over time.

Tips to Improve Rolling Growth

Optimise Continuously: Focus on consistency rather than short bursts of growth.
Balance Acquisition & Retention: Rolling averages reward steady retention as much as acquisition spikes.
Track with Complementary Metrics: Pair this analysis with CAC, CLTV, and conversion rate to get a complete picture.
Visualise Your Trendline: Plot rolling growth percentages across months to show long-term momentum.

FAQ's

What is a rolling 3-month average?

A rolling 3-month average is the average of a metric over the latest three months. It moves forward by one month each time new data comes in. It smooths out one-off spikes and dips in revenue, traffic or signups, so the underlying trend is easier to see and report.

How do I calculate rolling 3-month average growth?

First, average months 1 to 3 and months 2 to 4. Then calculate rolling growth % = ((rolling average 2 − rolling average 1) ÷ rolling average 1) × 100. For example, with ₹10,00,000, ₹11,00,000, ₹12,00,000 and ₹13,50,000, the averages are ₹11,00,000 and ₹12,16,667, which gives growth of about 10.6%.

Why use rolling average growth instead of month-on-month growth?

Month-on-month growth reacts to every single month, so one strong or weak month can distort the picture. Rolling average growth spreads that effect across three months. In the example above, raw MoM growth from month 3 to month 4 is 12.5%, while rolling growth is a steadier 10.6%.

Why does the calculator need four months of data?

Four months create two overlapping 3-month windows: months 1 to 3 and months 2 to 4. Both windows share months 2 and 3, so the change between them comes from month 4 replacing month 1. This is why rolling growth equals (month 4 − month 1) ÷ (month 1 + month 2 + month 3).

What does a negative rolling growth percentage mean?

A negative result means the latest three months averaged lower than the previous three-month window. In other words, month 4 came in lower than month 1. Check whether one unusual month caused the dip or whether the trend continues by re-running the calculator each month.
