How the Percentage Discount Calculator Works
Our percentage discount calculator uses the following formulas to calculate discount amounts and final prices:
Discount Amount Calculation
The discount amount is calculated by multiplying the original price by the discount percentage:
- Discount Amount = Original Price × (Discount Percentage ÷ 100)
For example, if the original price is ₹1,000 and the discount percentage is 20%:
- Discount Amount = ₹1,000 × (20 ÷ 100) = ₹1,000 × 0.2 = ₹200
Final Price Calculation
The final price is calculated by subtracting the discount amount from the original price:
- Final Price = Original Price - Discount Amount
Continuing with our example:
- Final Price = ₹1,000 - ₹200 = ₹800
Practical Examples of Percentage Discount Calculation
Example 1: Shopping Discount
A shirt is priced at ₹1,500 with a 25% discount:
- Discount Amount = ₹1,500 × 0.25 = ₹375
- Final Price = ₹1,500 - ₹375 = ₹1,125
You save ₹375 on your purchase.
Example 2: Seasonal Sale
A television with an original price of ₹30,000 is on sale with a 15% discount:
- Discount Amount = ₹30,000 × 0.15 = ₹4,500
- Final Price = ₹30,000 - ₹4,500 = ₹25,500
You save ₹4,500 on your purchase.
Frequently Asked Questions
How do I calculate a percentage discount?
To calculate a percentage discount, multiply the original price by the discount percentage (as a decimal), then subtract the result from the original price. For example, for a 20% discount on a ₹1,000 item: ₹1,000 × 0.2 = ₹200 discount, and the final price is ₹1,000 - ₹200 = ₹800.
How do I calculate the original price if I know the final price and discount percentage?
To calculate the original price from the final price and discount percentage, divide the final price by (1 - discount percentage as a decimal). For example, if the final price is ₹800 after a 20% discount: Original Price = ₹800 ÷ (1 - 0.2) = ₹800 ÷ 0.8 = ₹1,000.
How do I calculate the discount percentage if I know the original and final prices?
To calculate the discount percentage, subtract the final price from the original price to get the discount amount, then divide the discount amount by the original price and multiply by 100. For example, if the original price is ₹1,000 and the final price is ₹800: Discount Amount = ₹1,000 - ₹800 = ₹200, Discount Percentage = (₹200 ÷ ₹1,000) × 100 = 20%.
Can I use this calculator for currencies other than INR?
