How to Calculate Percentage Increase

Percentage increase measures the relative growth from an original starting quantity to a new quantity. It expresses the difference as a proportion of the original amount.

Percentage Increase = ((Final Value - Starting Value) / |Starting Value|) × 100

Step 1: Find Difference

Subtract the initial starting value from the new value to find the absolute gain: \(\Delta V = V_2 - V_1\).

Step 2: Divide by Base

Divide the absolute increase by the initial starting value: \(\Delta V / V_1\).

Step 3: Convert to Percent

Multiply the result by 100 to convert the decimal into a standard percentage rate.
