See the increase percentage, difference, and multiplier.
First subtract the original value from the new value. Divide that difference by the original value, then multiply by 100 to convert the result into a percentage.
Percent increase is useful for measuring salary growth, price changes, revenue gains, investment performance, population growth, test-score improvement, website traffic changes, and many other before-and-after comparisons.
The original value is used as the comparison base. It must not be zero because percentage increase cannot be calculated when the starting value is zero.
How do I calculate a percent increase?
Subtract the original value from the new value, divide by the original value, and multiply by 100.
Can the result be negative?
Yes. A negative result means the value decreased rather than increased.
Why can’t the original value be zero?
The formula requires division by the original value, and division by zero is undefined.
