How to use the Discount Calculator
- Enter the original price or MRP.
- Enter the discount %, or tap one of the quick buttons.
- If there’s an extra offer (bank card, coupon), enter it as extra discount.
- To work backwards, switch to Find discount % and enter the sale price.
Formula
Final price = Price × (1 − D₁/100) × (1 − D₂/100)
Discount % = (Original − Sale) ÷ Original × 100
- D₁ is the main discount and D₂ the extra discount, which is applied to the already-reduced price.
Worked example: 30% off plus an extra 10%
A jacket costs ₹2,499 with 30% off and an extra 10% with a bank card.
After 30%: ₹2,499 × 0.70 = ₹1,749.30. After the extra 10%: ₹1,749.30 × 0.90 = ₹1,574.37.
You save ₹924.63 – an effective discount of 37%, not 40%, because the second discount applies to the lower price.
Smart shopping tips
A big discount is not always the best deal:
- Compare the final price across shops, not the discount percentage.
- Check whether the MRP has been raised before the sale.
- Remember delivery charges and convenience fees when comparing online prices.
