Discount Calculator

How Discounts Work

A discount is a reduction from the regular price of a product or service. Understanding how to calculate discounts helps you make smart shopping decisions and compare deals effectively.

Types of Discounts

Percentage Discounts

The most common type: "25% off," "50% off," etc. The discount is calculated as a percentage of the original price.

Formula: Discount Amount = Original Price × (Discount % ÷ 100)

Dollar Amount Discounts

Fixed amount off: "$10 off," "$50 off," etc. This is straightforward subtraction.

Buy One Get One (BOGO)

Effectively a 50% discount when buying two items. Buy 2, Get 1 Free = 33.3% off per item.

Shopping Tips

1. Compare Discounts: 40% off $100 = $40 savings, vs $35 off $100 = $35 savings
2. Stack Discounts: Some stores allow coupon stacking for extra savings
3. Consider Tax: Sales tax is usually calculated AFTER the discount
4. Calculate Unit Price: Sometimes buying more at a smaller discount saves money
5. Beware of Fake Discounts: Compare to competitors' regular prices

Discount Math Examples

Example 1: $150 item at 30% off

• Discount: $150 × 0.30 = $45
• Final Price: $150 - $45 = $105

Example 2: $200 item, save $60

• Discount %: ($60 ÷ $200) × 100 = 30%
• Final Price: $200 - $60 = $140

Discount vs. Coupon

• Discount: Reduction in price, usually store-wide or category-wide
• Coupon: Specific to certain items or minimum purchase
• Rebate: Get money back after purchase (mail-in or instant)
