How Double Discount Works?
Stores often offer "50% + 20% Off". This does NOT mean 70% off! First, the 50% is applied to the original price. Then, the 20% is applied to the new discounted price.
📊 Example Calculation:
Item Price: ₹100
Discount 1 (50%): -₹50 → New Price: ₹50
Discount 2 (20% of ₹50): -₹10 → Final Price: ₹40
Total Savings: ₹60 (60%, not 70%)
📐 Discount Formulas
- Single Discount: Final Price = Price × (1 - Discount%)
- Double Discount: Final Price = Price × (1 - d1) × (1 - d2)
- With Tax: Final Price = Price × (1 - d1) × (1 - d2) × (1 + Tax%)
- Total Savings: Original Price - Price After Discount
💡 Smart Shopping Tips
- • Compare final prices, not discount percentages
- • Stackable coupons can save more than one big discount
- • Check if tax applies before or after discount
- • Use cashback apps for additional savings
❓ Frequently Asked Questions
How do I calculate the final price after double discount?
Apply the first discount to the original price, then apply the second discount to the resulting price. Formula: Final Price = Original Price × (1 - d1/100) × (1 - d2/100). For example, ₹100 with 50% + 20% = ₹100 × 0.5 × 0.8 = ₹40.
Does 50% + 20% equal 70% off?
No! 50% + 20% is 60% total off, not 70%. Because the second discount applies to the already reduced price. Use our calculator to see the exact final price.
Should tax be applied before or after discount?
In most retail scenarios, tax is applied to the discounted price (final sale price). However, some stores may apply tax before discount. Our calculator applies tax after all discounts, which is the most common practice.
How do I calculate the discount percentage?
Discount Percentage = (Discount Amount ÷ Original Price) × 100. For example, if you save ₹200 on a ₹1000 item, the discount is 20%. Our calculator automatically shows the total discount percentage for your convenience.
What's the best way to save money while shopping?
• Compare final prices across stores
• Stack coupons when possible
• Shop during sales (Black Friday, End of Season)
• Use cashback apps and loyalty programs
• Buy in bulk for frequently used items
⚠️ Note: Discount calculations are based on standard retail formulas. Always verify final price at checkout, as some stores may have different tax or discount policies.
