What month-over-month growth is

Month-over-month growth is the change between two months. It compares this month to the one before. So it shows short-term momentum. A positive value means it grew. A negative value means it fell. This tool puts a number on it.

How it is calculated

The tool takes the change from last month. It divides that by last month's figure. So the result is a share of the start. It then shows it as a percent. The result is your month-over-month growth. The calculator

What the result tells you

The result shows your month-over-month growth. A move from fifty thousand to fifty-five thousand is ten percent. A bigger rise lifts it. A fall makes it negative. So it shows the pace of change. It is a simple, clear number.

The last month

Your last month is the earlier figure. It is the starting point for the change. It is the base the growth is measured against. Use the value from the prior month. It drives the entire result here. Enter your last month.

The this month

Your this month is the newer figure. It is the latest value to compare. A higher figure lifts the growth. So this number drives the change. Use the value from the current month. It is what you measure against the base. Enter your this month.

The change

The tool also shows the change in raw terms. It is this month minus last month. Here it comes to five thousand. So you see the move in plain numbers. A rise is positive and a fall is negative. It sits behind the percent.

Positive versus negative growth

A positive value means the figure grew. This month is higher than last. So momentum is pointing up. A negative value means it shrank. This month came in lower. The sign tells the direction at a glance.

Why this matters

Month-over-month growth tracks short-term trends. It is common for sales, users, and revenue. So it flags a change fast. But single months can be noisy. A few months together show the real trend. Use it to spot momentum early.

How to use it

Enter your last month first. Add this month. Read the growth as a percent. Then see the raw change. Try a lower figure. Compare two months. Use it to track a trend.

If one figure changes

Raise last month by 10%, from $50,000 to $55,000, and the result moves from 10% to 0%, a change of -100.0%. The size of that move is what tells you where care is needed.

Reading the result

Use this to watch your monthly pace. Remember one month can be noisy. Seasonal swings can distort it. A longer run smooths the picture. Compare it to the same month last year too. Do not read too much into one jump. The trend matters more than a single month.

Frequently asked questions

How is month-over-month growth calculated?

It is this month's value minus last month's, divided by last month's, as a percentage. It suits revenue, users, sign-ups or any monthly metric.

When should I use it?

MoM is great for tracking steady momentum. For data with seasonal swings, also compare year-over-year so a regular dip is not mistaken for decline.
