AI Math SolverA percentage increase calculator measures how much a value has grown relative to where it started. Enter the original and new values to get the percent change, with the formula shown.
Percentage increase compares the size of a change to the original amount. It is the standard way to express growth in prices, populations, and scores.
Subtract the old value from the new one, divide by the old value, and multiply by 100. The calculator performs these steps and labels the result as an increase or decrease automatically.
Use the formula ((new − old) / old) × 100. A positive result is an increase; a negative result is a decrease.
Increase uses the original value as the base: (new − old) / old. Change (difference) between two values of similar status uses their average as the base instead — see the percentage difference calculator.
