📌 Understanding Percentage Decrease
Percentage decrease measures how much a value has dropped relative to its original value. The formula used is:
Percentage Decrease = [(Initial – Final) / Initial] × 100%
📌 Example Calculations
| Initial Value | Final Value | Percentage Decrease |
|---|---|---|
| 150 | 100 | 33.33% |
| 500 | 400 | 20% |
| 1000 | 700 | 30% |

❓ FAQs
Q1: How do I calculate percentage decrease?
✅ Use the formula [(Initial – Final) / Initial] × 100.
Q2: What does a 20% decrease mean?
✅ It means the final value is 80% of the initial value.
Q3: Can percentage decrease be greater than 100%?
✅ No, percentage decrease is always between 0% and 100%.
Q4: How do I calculate the new value after a percentage decrease?
✅ Multiply the initial value by (1 – percentage decrease/100).
Q5: What if my final value is higher than my initial value?
✅ The percentage decrease formula applies only when the final value is less than the initial value. If the final value is greater, use the percentage increase formula instead.
The percentage decrease calculator calculates the percentage decrease from one value to another value. Enter the initial value and the final value to find the percentage decrease. Also check out easy to use percentage calculator for all types of calculations.
How to calculate percentage decrease?
To calculate the percentage decrease, you can follow these four steps:
- Subtract the final value from the starting value:
- This gives you the amount of change.
- Formula: Change=Starting Value−Final Value
- Divide that amount by the absolute value of the starting value:
- This normalizes the change relative to the starting value.
- Formula: Relative Change=Change/Starting Value
- Multiply by 100 to get the percent decrease:
- This converts the relative change into a percentage.
- Formula: Percentage Decrease=Relative Change×100
- If the percentage is positive, it means there was a decrease:
- A positive result indicates a decrease.
Example Calculation
Let’s say you want to calculate the percentage decrease from a starting value of 100 to a final value of 80.
- Subtract the final value from the starting value:
- Change = 100 – 80 = 20
- Divide that amount by the absolute value of the starting value:
- Relative Change = 20/100=0.2
- Multiply by 100 to get the percent decrease:
- Percentage Decrease = 0.2×100=20%
- Check the sign:
- Since the result is positive, it indicates a 20% decrease.
By following these steps, you can calculate the percentage decrease for any two values. You might also like percentage increase calculator so check it out.
