Understanding Discounts and Savings
Discounts are reductions from the original price, typically expressed as percentages. Understanding how discounts work helps you make informed purchasing decisions and evaluate the true value of deals. Single discounts are straightforward, but multiple or stacked discounts require careful calculation since they're applied sequentially, not additively. Our calculator handles both scenarios to show you exactly how much you're saving.
Multiple Discounts and Stacking
When multiple discounts are applied, they work sequentially rather than being added together. For example, a 20% discount followed by a 10% discount doesn't equal 30% off. Instead, the 20% is applied first, then the 10% is applied to the already-reduced price. This results in a total discount of 28% (not 30%). Understanding this concept helps you accurately calculate savings from promotional offers and discount combinations.

To calculate a discount: Discount Amount = Original Price × (Discount Percentage / 100), then Final Price = Original Price - Discount Amount. For example, 20% off $100 = $100 × 0.20 = $20 discount, so final price = $80.
Discount percentage is the rate of reduction (like 25% off), while discount amount is the actual dollar value saved. A 25% discount on $100 gives a $25 discount amount and $75 final price.
To find original price from discounted price: Original Price = Discounted Price / (1 - Discount Percentage/100). For example, if an item costs $80 after a 20% discount: $80 / (1 - 0.20) = $80 / 0.80 = $100.
Multiple discounts are applied sequentially, not added together. For 20% + 10% discounts on $100: First discount = $100 × 0.20 = $20, new price = $80. Second discount = $80 × 0.10 = $8, final price = $72 (not $70).
'20% off' means you pay 80% of original price, while 'pay 80% of original price' means the same thing. The discount is 20%, and you pay the remaining 80%. Both result in the same final price.
Total savings equals the discount amount: Savings = Original Price - Final Price, or Savings = Original Price × (Discount Percentage / 100). This shows exactly how much money you save from the discount.
Yes, discount percentage = ((Original Price - Sale Price) / Original Price) × 100. For example, if an item was $100 and now costs $75: ((100 - 75) / 100) × 100 = 25% discount.
Typically, discounts apply to the pre-tax price, then tax is calculated on the discounted amount. For $100 item with 20% discount and 8% tax: $100 - $20 = $80, then $80 × 1.08 = $86.40 final price including tax.
It depends on the original price. Fixed discounts ($10 off) are better on lower-priced items, while percentage discounts (20% off) are better on higher-priced items. Compare the actual savings amount to determine which is better.
Quantity discounts often use tiered pricing. Calculate the discount for each tier separately, then sum the results. For example: 1-10 items at full price, 11-20 items at 10% off, 21+ items at 20% off. Apply the appropriate rate to each quantity range.
