Find the final price and how much you save on a discounted item.
The final price after a percentage discount is calculated as Original Price × (1 − Discount% / 100). If there's an additional flat discount (like a coupon code applied after the percentage discount), it's subtracted after the percentage discount is applied, not before — the order matters for the final total.
This is also useful in reverse — knowing exactly how much you're saving in rupee terms, not just the percentage, can help you judge whether a 'sale' is actually a meaningful saving on a specific item you're considering.
Yes — applying a flat discount after a percentage discount gives a different (usually lower) final price than applying it before, since the percentage discount would then apply to a larger base amount. Check how your specific retailer applies combined discounts.
Stacked percentage discounts are usually applied sequentially, not added together — a 20% discount followed by an extra 10% off gives a combined discount of 28% (not 30%), since the second discount applies to the already-reduced price.
Because the rupee amount saved scales with the original price — a 20% discount on a ₹500 item saves ₹100, while the same 20% on a ₹5,000 item saves ₹1,000, even though the percentage is identical.
