Percentage Decrease Formula
The formula for calculating percentage decline is:
Percentage Decrease = ((Original Value - New Value) ÷ Original Value) × 100This formula can be broken down into three essential steps:
- Subtract the new value from the original value.
- Divide the difference by the original value.
- Multiply the result by 100 to convert to a percentage.
If a car’s value depreciated from $25,000 to $20,000, the calculation would be:
Percentage Decrease = ((25,000 - 20,000) ÷ 25,000) × 100
= (5,000 ÷ 25,000) × 100
= 0.2 × 100
= 20%How do I calculate percent reduction?
Here’s a step-by-step approach:
- Identify your values:
- Record your starting (original) value.
- Record your final (new) value.
- Calculate the difference:
- Subtract the new value from the original value.
- Divide by original:
- Take the difference and divide it by the original value.
- Convert to percentage:
- Multiply the result by 100.
A city’s water consumption decreased from 1,200,000 gallons to 900,000 gallons after implementing conservation measures.
Reduction = ((1,200,000 - 900,000) ÷ 1,200,000) × 100
= (300,000 ÷ 1,200,000) × 100
= 0.25 × 100
= 25%How do you decrease 20% of a number?
To decrease a number by 20%, you can either:
- Calculate 20% of the number and subtract it.
- Multiply the number by 0.8 (100% – 20%).
Method 1
Original Number × (20 ÷ 100) = Amount to subtract
Original Number - Amount to subtract = Final NumberMethod 2
Original Number × (1 - 0.20) = Final NumberDecreasing 150 by 20%
- Method 1:
- 150 × (20 ÷ 100) = 30 (amount to subtract)
- 150 – 30 = 120 (final answer)
- Method 2:
- 150 × 0.8 = 120 (final answer)
