How to Calculate Discount: Formula & Guide
Calculating discounts manually is simple once you know the core formulas. Whether you are shopping during a festival sale or creating an invoice for a client, understanding these numbers is essential.
1. Finding the Discount Amount
This tells you exactly how much money you are saving.
Example: A ₹2,000 shirt at 15% off:
₹2,000 × (15 / 100) = ₹300 saved.
2. Finding the Final Price
This is the final amount you have to pay after the discount.
Example: Continuing from the left:
₹2,000 - ₹300 = ₹1,700 final price.
Single vs. Successive (Double) Discounts
Retailers often use terms like "50% + 20% Off". This does not mean 70% off! Here is how successive discounts actually work.
Single Discount (e.g. 70% Off)
Applied directly to the original price. For a ₹1,000 item, a straight 70% discount means you save ₹700, and you pay ₹300.
Successive Discount (50% + 20%)
Step 1: 50% off ₹1,000 = ₹500.
Step 2: 20% off the new ₹500 price = ₹100.
Final Price: ₹500 - ₹100 = ₹400.

Frequently Asked Questions
1. How do I calculate a 15% discount?
Divide 15 by 100 to get 0.15. Multiply this by the original price to find your savings. Subtract the savings from the original price to get the final amount.
2. Does a discount apply before or after tax?
In standard accounting and GST rules, trade discounts are usually applied before tax. You calculate the tax on the final discounted value.
3. Is 50% + 50% off equal to free?
No! The first 50% reduces the price by half. The second 50% applies to that *new* half-price. Ultimately, a 50% + 50% off sale means you get 75% off the total original price.
4. How accurate is this calculator?
Our calculator provides instant, 100% accurate standard mathematical discounts rounded to two decimal places (standard currency format).
