What Is a Discount Calculator?
A Discount Calculator helps you instantly find the final price after applying a percentage or flat discount to any product or service. Enter the original price and the discount — either as a percentage (e.g. 25% off) or as a fixed amount (e.g. ₹100 off) — and the tool shows your savings and the exact price to charge. It's useful for retailers setting sale prices, e-commerce sellers running promotions, and buyers verifying advertised deals.

Frequently Asked Questions
How do I calculate a discount percentage?
Discount % = (Discount Amount ÷ Original Price) × 100. Example: original ₹500, discounted to ₹400 — discount = ₹100, which is 20%.
How do I find the final price after a discount?
Final Price = Original Price × (1 − Discount% ÷ 100). Example: ₹1000 with 15% off = ₹1000 × 0.85 = ₹850.
What is the difference between a flat discount and a percentage discount?
A flat discount is a fixed amount off (e.g. ₹50 off). A percentage discount scales with the price (e.g. 10% off). For higher-value items, a percentage discount gives a bigger saving.
Can I calculate the original price if I know the discount and final price?
Yes. Original Price = Final Price ÷ (1 − Discount% ÷ 100). Example: final price ₹800, discount 20% → Original = 800 ÷ 0.8 = ₹1000.
Is GST applied on the original price or the discounted price?
Under India's GST rules, GST is typically applied on the transaction value (the discounted price you actually charge the customer), not the MRP.
