The discount calculator handles both forward and reverse discount calculations in one tool. Calculate sale prices from original prices and discount percentages, or work backwards to find the original price when you only know the sale price and discount.
Forward discount: Original price → Sale price
Reverse discount: Sale price → Original price
Both calculations show clear formula steps so you understand exactly how discounts work. The discount amount itself is calculated using basic percentage math—learn more with our percent of number calculator.
How Discount Formulas Work
Understanding the math behind discounts helps you shop smarter and verify advertised deals.
Forward Discount Formula
Sale Price = Original × (1 − Discount ÷ 100)
Example: A jacket costs $89.99 with a 30% discount
$89.99 × (1 − 30 ÷ 100) = $89.99 × 0.70 = $62.99
Reverse Discount Formula
Original Price = Sale Price(1 − Discount ÷ 100)
Example: A shirt is on sale for $36 after a 40% discount
$36 ÷ (1 − 40 ÷ 100) = $36 ÷ 0.60 = $60 original

Real Shopping Scenarios
Discount calculations are essential for smart shopping and budget planning. Here are practical examples:
Scenario 1 - Forward Discount: You see a shirt marked $60 with a "25% off" sign. Using the forward formula: $60 × 0.75 = $45 sale price. You'll save $15.
Scenario 2 - Reverse Discount: A store advertises "40% off everything!" and you see an item priced at $36. Was it really worth more before? Using reverse calculation: $36 ÷ 0.60 = $60 original price. The discount checks out.
Scenario 3 - Comparing Deals: Store A offers 30% off $100. Store B offers 25% off $80. Calculate final prices: Store A = $70, Store B = $60. Store B wins despite the smaller discount percentage.

Business Pricing Context
Discount calculators aren't just for shoppers—business owners use them for pricing strategy and analysis.
Retail Pricing: Calculate sale prices for promotions while maintaining target margins. If your cost is $40 and you need a 50% margin, your original price should be $80. A 25% discount brings it to $60.
Competitive Analysis: Use reverse discount calculations to understand competitor pricing strategies. If they're selling at $45 after a 20% discount, their original price was $56.25.
Discount vs. Markup vs. Margin: These three concepts are often confused. A discount reduces price from the original. A markup adds to cost to set selling price. Margin is profit as a percentage of selling price.
