1. What is Percentage Deduction?

Percentage deduction is a mathematical calculation that determines how much to subtract from an original amount based on a specified percentage. It's commonly used in financial calculations like discounts, taxes, commissions, and reductions.

2. How Does the Calculator Work?

The calculator uses the percentage deduction formula:

Where:

• Amount — The original value before deduction
• Percent — The percentage to be deducted (e.g., 15 for 15%)
• Deduction — The calculated amount to subtract

Example: For $200 with a 25% deduction: $200 × (25/100) = $50 deduction, leaving $150 remaining.

3. Practical Applications

Common Uses:

• Calculating discounts during sales
• Determining tax withholdings
• Calculating commission reductions
• Adjusting budgets or expenses
• Financial planning and analysis

4. Using the Calculator

Instructions:

1. Enter the original amount in the first field
2. Enter the percentage to deduct in the second field
3. Click "Calculate" to see the deduction amount and remaining value

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for percentage increases?
A: Yes, but you would add the deduction amount to the original instead of subtracting it.

Q2: How do I calculate the final amount after deduction?
A: Subtract the deduction amount from the original amount (shown as "Remaining Amount" in results).

Q3: What's the difference between percentage off and percentage of?
A: "Percentage off" means deducting from the total (like a discount), while "percentage of" means calculating a portion of the total.

Q4: How do I reverse a percentage deduction?
A: To find the original amount before a deduction: Final Amount ÷ (1 - (Percentage/100)).

Q5: Can I enter percentages over 100%?
A: The calculator allows it, but deductions over 100% would result in a negative remaining amount.
