What Is a Percentage Increase?

A percentage increase refers to the amount of change from an original value to a new value expressed as a percentage. It helps quantify how much something has grown relative to its initial state. The formula used for calculating this is straightforward:

For instance, if your company’s revenue went from $50,000 to $60,000, you would apply the percentage increase formula to determine that there was a 20% rise in income.

Understanding this concept is crucial because it allows individuals and businesses alike to measure progress, evaluate investments, track trends, and make informed decisions based on numerical evidence.

Percentage Increase vs. Decrease

It’s important to note that while the same formula applies, the interpretation differs depending on whether you’re measuring growth (increase) or decline (decrease):

If the result is positive, it indicates a percentage increase; negative results indicate a percentage decrease.

For example:

• An item priced at $100 drops to $80 → (-20%) decrease
• An investment grows from $1,000 to $1,200 → (+20%) increase

This distinction is vital for accurate reporting and forecasting.
