Reductions refer to the amount of a decrease, such as a decrease in salary or a decrease in budget. Using a percentage to represent a reduction measures the amount of the reduction in relation to the original amount, rather than just a raw number. For example, a $5,000 decrease in salary for a president of a large company would be a lot less significant than a $5,000 decrease in salary for someone making $25,000 or $30,000 per year. Calculating such losses in terms of percentages helps put them in perspective.

#### TL;DR (Too Long; Didn't Read)

The formula for finding the percentage of reduction is:

*P* = *a*/*b* × 100

Where *P* is the percentage of reduction, *a* is the amount of the reduction and *b* is the original amount that was reduced.

Subtract the final amount from the initial amount to find the amount of the reduction. For example, if your salary was $59,000 and it was reduced to $56,000, you'd have:

Divide the amount of the reduction by the original amount to find the rate of reduction. In this example, you have:

Multiply the rate of reduction by 100 to find the percentage reduction. In this example, you have:
