Home >> Percentages >> Percentage Decrease >> Percentage Decrease
At times, while comparing two quantities, we also need to know the percentage decrease in value of given quantities. So the formula to find the percentage decrease is -
Percentage Decrease = (Decrease in value / Base Value) X 100
Let's study some examples to understand the percentage decrease
Example 1 : Julie reduced her weight from 80kg to 72kg in three months. Find percentage weight loss ?
Solution : Given things are
Original Weight : 80 kg
Current Weight : 72 kg
Now we will find the decrease in weight loss -
Decrease in weight = Original Weight - Current Weight
Decrease in weight = 80 - 72
Decrease in weight = 8 kg
Now we will apply the formula of percentage decrease and we get -
Percentage Decrease = (Decrease in value / Base Value) X 100
Percentage Decrease = (Decrease in Weight / Base Weight) X 100
Percentage Decrease = (8 / 80) X 100
Percentage Decrease = 0.10 X 100
Percentage Decrease = 10
So total percentage decrease in weight is 10 kg
Example 2 : Total sales reduced from 200 to 100. Find the percentage decrease in sales ?
Solution : Given things are -
Past total sales = 200
Current total sales = 100
Now we will find the decrease in sales -
Decrease in sales = Past Sales - Current Sales
Decrease in sales = 200 - 100
Decrease in sales = 100
Now we will apply the formula of percentage decrease and we get -
Percentage Decrease = (Decrease in Value / Base Value) X 100
Percentage Decrease = (Decrease in Sales / Past Total Sales) X 100
Percentage Decrease = (100 / 200) X 100
Percentage Decrease = 0.50 X 100
Percentage Decrease = 50%
So total percentage in decrease in sales is 50%
