Percent Increase/Decrease

Percent increase is the amount of increase expressed as a percentage of the original amount. It is calculated using the formula: ((New Value - Original Value) / Original Value) x 100.

Percent decrease is the amount of decrease expressed as a percentage of the original amount. It is calculated using the formula: ((Original Value - New Value) / Original Value) x 100.

If the new value is greater than the original value, it is an increase. If the new value is less than the original value, it is a decrease.

Percent Decrease = ((65.50 - 52.40) / 65.50) x 100 = 20%.

Percent Change = ((12 - 8) / 12) x 100 = 33%.

New Amount = Original Amount - (Original Amount x Percent Decrease).

Percent Decrease = ((40 - 30) / 40) x 100 = 25%.

Original Price = Sale Price / (1 - Percent Decrease) = 52.40 / (1 - 0.20) = $65.50.

Percent Increase = ((65 - 50) / 50) x 100 = 30%.

A 10% decrease means the new value is 90% of the original value.
