Discount Calculator

🔑 Key Discount Concepts

• Discount Formula: Discount Amount = Original Price × (Discount % ÷ 100). Final Price = Original Price - Discount Amount.
• Savings Percentage: The percentage of original price saved. Always equals the discount percentage for single discounts.
• Stacked Discounts: Apply sequentially, not additively. 20% then 10% = 28% effective discount, not 30%.
• Reverse Calculation: Original Price = Sale Price ÷ (1 - Discount % ÷ 100). Useful to verify realistic original prices.
• Best Deals: Compare actual dollar savings, not just percentages. 50% off $20 = $10 saved, but 25% off $50 = $12.50 saved.

Example: Calculate discount for $200 item with 25% off

Step 1: Original Price = $200

Step 2: Discount Percentage = 25%

Step 3: Discount Amount = $200 × (25 ÷ 100) = $200 × 0.25 = $50

Step 4: Final Price = $200 - $50 = $150

You save $50 (25% of original price). The final price is $150, which is 75% of the original price.

• Compare actual savings: Don't just look at percentages - calculate dollar amounts. 50% off $20 = $10 saved, but 25% off $50 = $12.50 saved.
• Verify original prices: Some stores inflate "original" prices before applying discounts. Check if the original price was ever actually charged.
• Stack discounts wisely: When possible, apply larger discounts first. Some stores allow stacking, others don't - check fine print.
• Consider quality: A 50% off poor quality item may not be better than 20% off a high-quality item. Factor in durability and value.
• Check return policies: Clearance items are often final sale. Make sure you're satisfied with the item before purchasing.
• Factor in additional costs: Consider shipping, taxes, and fees when comparing final prices across retailers.
