Excel formulas are a great way to analyze your data and quickly calculate results. One of the most useful formulas you can use is the percent change formula, which can be used to track growth or decline over time.

The basic formula for calculating the percent change is: (New Value – Old Value) ÷ Old Value. For example, if you want to calculate the percent change from June to July, you would take the new value for July (let's say it's 5) and subtract the old value for June (let's say it's 3). So the formula would look like this: (5-3) ÷ 3 = 0.66 or 66%.

This formula can be used to track the change in any metric over time. It's a great tool for quickly understanding the significance of changes in data and whether a trend is increasing or decreasing. You can even use the same formula to compare multiple data points over time, such as comparing June and July to August and September.

It's important to note that the percent change formula will always give you relative results, meaning it won't tell you the absolute increase or decrease in value. To calculate the absolute change, you would need to use a different formula.

In conclusion, the percent change formula is a useful tool for analyzing and tracking data over time in Excel. By understanding how to use this formula, you'll be able to quickly determine the relative growth or decline of a metric.
