Multiple Discount Calculation: Master Sequential & Compound Discounts

Multiple discounts are everywhere—from festival sales combining store discounts with card offers to business deals stacking volume discounts with seasonal promotions. Understanding how to calculate these correctly can save you money and help you make better purchasing decisions.

🔍 Understanding Multiple Discounts

Key Concept:

When multiple discounts are applied, they work sequentially on the reduced price, not on the original price. Each subsequent discount applies to the already-discounted amount.

✅ Correct Method

Item: ₹1,000 with 20% + 15% discounts

1. Apply 20%: ₹1,000 × 0.80 = ₹800
2. Apply 15% to ₹800: ₹800 × 0.85 = ₹680

Final Price: ₹680
Total Discount: 32% (not 35%)

❌ Wrong Method

Item: ₹1,000 with 20% + 15% discounts

1. Add percentages: 20% + 15% = 35%
2. Apply 35%: ₹1,000 × 0.65 = ₹650

Wrong Result: ₹650
₹30 more discount than actual!

📐 Sequential Discount Formula

Universal Formula for Multiple Discounts

Final Price = Original Price × (1 - D₁/100) × (1 - D₂/100) × (1 - D₃/100)...

Where D₁, D₂, D₃ are discount percentages in order

Example Calculation:

Original Price: ₹5,000 | Discounts: 25%, 10%, 5%

Step-by-step:

• ₹5,000 × (1 - 25/100) × (1 - 10/100) × (1 - 5/100)
• ₹5,000 × 0.75 × 0.90 × 0.95
• ₹5,000 × 0.64125
• Final Price: ₹3,206.25

Total Discount: ₹1,793.75 (35.875%)
