Q1: How do I calculate a discount percentage?
To calculate discount percentage: Discount % = (Discount Amount / Original Price) × 100. For example, if an item is $100 and you save $20, the discount is (20/100) × 100 = 20%.
Q2: What is the difference between discount amount and discount percentage?
Discount amount is the dollar value you save (e.g., $20 off). Discount percentage is the rate of discount (e.g., 20% off). The calculator converts between them: discount amount = original price × (discount % / 100).
Q3: How do I calculate the final price after discount?
Final Price = Original Price - Discount Amount, or Final Price = Original Price × (1 - Discount % / 100). For example, $100 with 20% off = $100 × 0.80 = $80.
Q4: Can I use this for multiple discounts or stacked discounts?
This calculator handles a single discount. For multiple discounts, calculate the first discount, then use the discounted price as the new original price for the second discount. Note: stacking discounts doesn't mean adding percentages (20% + 10% ≠30%).
Q5: What if the discount percentage is more than 100%?
A discount cannot exceed 100%. If you enter more than 100%, the calculator will show an error or invalid result. A 100% discount means the item is free.
Q6: How do I calculate what percentage discount I received?
If you know the original price and final price: Discount % = [(Original Price - Final Price) / Original Price] × 100. For example, if something was $100 and you paid $75: [(100-75)/100] × 100 = 25% discount.
