Frequently Asked Questions
How do I calculate the discounted price?
To calculate the discounted price (or sale price):
1. Take the original price
2. Multiply it by the discount percentage
3. Divide by 100 to get the discount amount
4. Subtract the discount amount from the original price
Formula: Final Price = Original Price - (Original Price × Discount Percentage / 100)
For example, if an item originally costs ₹1,000 and has a 20% discount:
Discount Amount = ₹1,000 × 20 / 100 = ₹200
Final Price = ₹1,000 - ₹200 = ₹800
How do I calculate the original price from a discounted price?
To calculate the original price when you know the final (discounted) price and discount percentage:
Formula: Original Price = Final Price / (1 - Discount Percentage / 100)
For example, if the sale price is ₹800 with a 20% discount:
Original Price = ₹800 / (1 - 20/100) = ₹800 / 0.8 = ₹1,000
This "reverse calculation" is useful when you see a sale item and want to know what the original price was.
How do I calculate the discount percentage?
To calculate the discount percentage when you know the original and final prices:
1. Subtract the final price from the original price to get the discount amount
2. Divide the discount amount by the original price
3. Multiply by 100 to get the percentage
Formula: Discount Percentage = (Original Price - Final Price) / Original Price × 100
For example, if an item originally costs ₹1,000 and is on sale for ₹750:
Discount Amount = ₹1,000 - ₹750 = ₹250
Discount Percentage = (₹250 / ₹1,000) × 100 = 25%
How do I calculate tax on discounted prices?
To calculate tax on a discounted price:
1. Calculate the discounted price first (Original Price - Discount Amount)
2. Multiply the discounted price by the tax rate percentage
3. Divide by 100 to get the tax amount
4. Add the tax amount to the discounted price for the final price with tax
For example, if the discounted price is ₹800 and the tax rate is 18% (GST):
Tax Amount = ₹800 × 18 / 100 = ₹144
Total Price with Tax = ₹800 + ₹144 = ₹944
What is the difference between discount rate and discount factor?
Discount Rate: This is the percentage by which the original price is reduced. For example, a 20% discount rate means the price is reduced by 20% of the original price.
Discount Factor: This is the multiplier used to calculate the final price directly. It equals (1 - Discount Rate/100). For example, a 20% discount rate gives a discount factor of 0.8, meaning the final price is 80% of the original price.
Formulas:
- Discount Rate = 20% (represented as a percentage)
- Discount Factor = 1 - 20/100 = 0.8
- Final Price = Original Price × Discount Factor = Original Price × 0.8
