Formula & Mathematics
Compound Discount Formula
Final = Price × (1 - Disc₁%) × (1 - Disc₂%) + Sales Tax
Handles sequential stacked promotions (e.g. 20% off plus an extra 10% coupon).
Worked Example
₹3,000 shoes on 30% sale with an extra 10% coupon
Original = ₹3,000, 30% off, plus 10% extra coupon.
• Price after 30% = ₹3,000 - ₹900 = ₹2,100
• Price after 10% coupon = ₹2,100 - ₹210 = ₹1,890
• Total savings = ₹3,000 - ₹1,890 = ₹1,110 (37% effective discount)
You pay ₹1,890, saving ₹1,110.
Frequently Asked Questions
Because the second discount applies to the already discounted price, not the original price.
