1. What is Percentage Deduction?

Percentage deduction is a mathematical operation that reduces a given amount by a specified percentage. It's commonly used in financial calculations such as discounts, tax deductions, or performance decreases.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Amount \) — The original value before deduction
• \( Percent \) — The percentage to be deducted (0-100)

Explanation: The formula converts the percentage to a decimal fraction (by dividing by 100), subtracts this from 1 to get the remaining fraction, then multiplies by the original amount.

3. Practical Applications

Details: This calculation is widely used in:

• Calculating sale prices after discounts
• Determining net pay after tax deductions
• Adjusting budgets for percentage cuts
• Calculating performance decreases

4. Using the Calculator

Tips: Enter the original amount (must be positive) and the percentage to deduct (0-100). The result will show the amount after deduction.

5. Frequently Asked Questions (FAQ)

Q1: How is this different from adding a percentage?
A: Adding a percentage would use the formula: Amount × (1 + Percent/100). Deducting reduces the amount while adding increases it.

Q2: What if I want to deduct multiple percentages?
A: You can chain the calculations, applying each percentage deduction sequentially to the previous result.

Q3: Can I use this for non-financial calculations?
A: Yes, this works for any quantity where you need to reduce by a percentage - measurements, scores, etc.

Q4: How do I calculate the percentage saved?
A: The amount saved is simply Original Amount × (Percent/100). The result shows what you pay after the saving.

Q5: Does the order matter when applying multiple deductions?
A: Mathematically, the order changes the result. For example, deducting 10% then 20% gives a different result than 20% then 10%.
