What is Percentage Decrease Calculator?
A Percentage Decrease Calculator is a tool that calculates the percentage decrease between two numbers. It’s useful when you want to calculate the amount of decrease between an initial value and a final value expressed as a percentage.
% Decrease = (Initial Value – Final Value) / Initial Value * 100
The calculation involves subtracting the final value from the initial value and then dividing that result by the initial value. The resulting quotient is then multiplied by 100 to express the answer as a percentage.
Here’s an example to help illustrate the formula:
Suppose the initial value is 100 and the final value is 80.
To calculate the percentage decrease:
% Decrease = (100 – 80) / 100 * 100
% Decrease = 20 / 100 * 100
% Decrease = 20%
So the percentage decrease between 100 and 80 is 20%.
In this example, the initial value is 100, the final value is 80, and the percentage decrease is 20%. The percentage decrease tells us how much the value has decreased from the initial value, and it’s expressed as a percentage.
How to Calculate Percentage Decrease?
Calculating the percentage decrease involves determining the difference between two values and expressing that difference as a percentage of the initial value. Here are the steps to follow:
Step 1: Determine the Initial Value (IV)
The initial value is the starting or original value before the decrease. It’s important to know the initial value in order to calculate the percentage decrease.
Step 2: Determine the Final Value (FV)
The final value is the ending or final value after the decrease. It’s important to know the final value in order to calculate the percentage decrease.
Step 3: Subtract the Final Value from the Initial Value
Subtract the final value from the initial value to determine the difference between the two values.
Difference = Initial Value – Final Value
Step 4: Divide the Difference by the Initial Value
Divide the difference by the initial value to get the decimal value of the percentage decrease.
Decimal Value = Difference / Initial Value
Step 5: Multiply the Decimal Value by 100
Multiply the decimal value by 100 to express the percentage decrease as a percentage.
