About Discount Calculator
This calculator computes the final price after applying a percentage discount, or reverse-calculates the original price from a discounted price and discount rate. Formula: Discounted price = Original price x (1 - Discount% / 100). Discount amount = Original price x Discount% / 100. Savings percentage from cost = (Discount amount / Original price) x 100.
Retail discount types: Flat discount (fixed amount off); Percentage discount (most common, e.g. 20% off); Buy-one-get-one (BOGO, effectively 50% off per item); Cashback (discount credited back, not upfront); Tiered discount (higher discount for larger purchase quantities). GST implication: GST is charged on the post-discount price, not the original MRP. For example, a product with MRP Rs 1,000 and 18% GST, after a 20% discount the taxable value is Rs 800 and GST is Rs 144, totalling Rs 944. Always compare effective prices after tax rather than advertised discount percentages for accurate savings comparison.
