Discount savings = Original Price × Discount % / 100. Final price = Original Price × (1 - Discount %). For stacked discounts (e.g., 20% then 10%), multiply the remaining percentages: 0.80 × 0.90 = 0.72, giving a combined 28% discount — not 30%. Always check whether discounts are additive or multiplicative.
