Common Questions

Discount Amount = Original Price × (Discount % ÷ 100). The Final Sale Price = Original Price - Discount Amount.
Successive discounts are applied sequentially, not by adding percentages. For example, 30% off on ₹1000 reduces it to ₹700; an extra 10% off takes ₹70 off ₹700, resulting in ₹630 (an effective 37% discount, not 40%).
Under Indian tax law, GST is applied to the final discounted sale price, not the original MRP. Formula: Final Price = Discounted Price + (Discounted Price × GST Rate / 100).
Discount Percentage = ((Original Price - Sale Price) ÷ Original Price) × 100.
