Frequently Asked Questions

How do I calculate discount on a product?

Discount Amount = Original Price × Discount Percentage / 100. Final Price = Original Price − Discount Amount. For example, a ₹2,000 item at 25% off: Discount = ₹500, you pay ₹1,500. This calculator does this instantly for any price and percentage.

How to calculate the original price before discount?

Original Price = Discounted Price / (1 − Discount% / 100). For example, if you paid ₹750 after a 25% discount: Original = 750 / (1 − 0.25) = 750 / 0.75 = ₹1,000. This reverse calculation helps you verify deals.

Is a 50% + 20% discount the same as 70% off?

No. Successive discounts are applied one after another, not added together. 50% off ₹1,000 = ₹500, then 20% off ₹500 = ₹100. Total discount = ₹600, which is 60% — not 70%. Always calculate each discount step separately.

How do I compare two discount offers?

Convert both offers to the final price and compare. "Buy 1 Get 1 Free" on a ₹500 item = ₹250 per unit. "40% off" on the same item = ₹300 per unit. BOGO is the better deal. This calculator helps you quickly compute the final amount for any discount.

Does GST apply before or after the discount?

In India, GST is calculated on the actual transaction value — which is the price after discount. So if a ₹1,000 item is discounted to ₹800 and GST is 18%, the tax is 18% of ₹800 = ₹144, making the total ₹944 (not ₹1,180 minus discount).
