Percent Increase Calculator
Percent Increase Calculator
Understanding percentage changes is crucial in finance, business, and everyday decision-making. The Percent Increase Calculator helps you instantly determine how much a value has increased or grown over time — expressed as a percentage.
Whether you’re analyzing profit margins, salary growth, or sales data, this calculator offers a fast and accurate way to measure growth percentages with just two numbers: the original value and the new value.
What Is a Percent Increase?
A percent increase shows how much something has grown in proportion to its original amount. It tells you the percentage difference between an initial value and a new, larger value.
For example:
If your salary rises from $2,000 to $2,200, your percent increase is 10%.
It’s a simple yet powerful tool used in finance, economics, statistics, and even personal budgeting to track growth and progress.
Percent Increase Formula
The basic formula to calculate percent increase is: Percent Increase=(New Value−Old ValueOld Value)×100\text{Percent Increase} = \left( \frac{\text{New Value} – \text{Old Value}}{\text{Old Value}} \right) \times 100Percent Increase=(Old ValueNew Value−Old Value)×100
Example:
If a stock price rises from $100 to $120: (120−100)100×100=20%\frac{(120 – 100)}{100} \times 100 = 20\%100(120−100)×100=20%
✅ Result: The stock increased by 20%.
This formula works for any scenario — money, quantity, measurements, or other data points.
