# How to Calculate a Percentage Decrease in Revenue From Year to Year

Original post by C. Taylor of Demand Media

If your revenues have degraded from a previous year, you might want a reliable way to track this decrease. Pure numbers won't do it, because they are meaningless without a reference. As an example a \$10,000 reduction might be significant for a very small firm, but if revenues are generally \$20 million for a larger business, this reduction is a drop in the bucket. Percentages are a better gauge of how much revenue has been lost compared to the previous year.

### Step 1

Subtract the current year's total revenue from the previous year. If the number is negative, then you know you had a loss. For example, if the current year's revenues were \$200,000, but last year they were \$250,000, then revenue is down \$50,000 from the previous year.

### Step 2

Divide the change in revenue by the previous year's total revenue. In the example, \$50,000 divided by \$250,000 equals .20.

### Step 3

Multiply this number by 100 to convert the figure into percentage format. In the example, the 0.20 change represents a 20 percent decrease in revenue.

```
inline.find('script').remove();
jQuery('#article p').eq(1).after(inline);
});

```
