How to Calculate Discount — Complete Guide
Whether you're shopping during Diwali sales, Big Billion Days, or just checking an offer — knowing how discounts work helps you understand the actual saving. This calculator supports single, successive, and GST-inclusive discounts.
Discount Formula
Discount Amount = Original Price × Discount% / 100
Final Price = Original Price − Discount Amount
Successive Discounts Are NOT Additive
A common mistake: 30% + 20% off ≠ 50% off! It's actually 30% off first, then 20% off the reduced price. For ₹1,000: First discount (30%) = ₹700, then 20% of ₹700 = ₹560. Effective discount = 44%, not 50%.
Discount + GST — What Online Shoppers Actually Pay
If an item is ₹5,000 with 20% discount + 18% GST: Discounted price = ₹4,000, GST = ₹720, Final = ₹4,720. You save ₹280, not ₹1,000!
FAQs
Q: How do I find the original price from discounted price?
A: Original = Discounted Price / (1 − Discount% / 100)
