The percentage change calculator is used to determine the percentage increase or decrease between values.
The following formula is used:
Percentage Change = (Final Value - Starting Value) ÷ Starting Value × 100
It measures how much a value has increased or decreased compared to its original value. Let's take some examples:
Find the percent change from 150 to 223.
Apply the values in the formula:
= (223 - 150) ÷ 150 × 100
= (73 ÷ 150) × 100
= 0.4866 × 100
= 48.66% (increase)
A product price drops from $299 to $149. Find the percent drop.
= (149 - 299) ÷ 299 × 100
= (-150 ÷ 299) × 100
= -0.5017 × 100
= -50.17% (decrease)
