Discount Calculator: Real Price After Discounts
Calculate discounts, compare deals, and find the real price.
Determine the final price after percentage or fixed discounts.
Formula
Discount = Original × (%/100). Final = Original - Discount.
Stacked Discounts Trap
"50% + 30% off" is NOT 80%. Pay 50%, then 70% of that = 35%. Total discount: 65%.
Comparing Deals
Always calculate the final price. Compare final prices, not discount percentages.
Coupon vs Percentage
For $50: 25% off = $37.50. $10 coupon = $40. Percentage wins. For $200: 25% = $150. $10 = $190. Percentage wins bigger.
