Calculate discounts, sale prices, and savings
Discount calculations are essential for smart shopping, business pricing strategies, and financial planning. Understanding how discounts work helps you make informed purchasing decisions and maximize your savings.
When multiple discounts are applied, they're typically calculated sequentially, not additively. For example, a 20% discount followed by a 10% discount doesn't equal 30% off. Instead, the second discount is applied to the already-reduced price, resulting in a 28% total discount.
Smart shoppers use discount calculations to compare deals, time purchases around sales, and understand the true value of promotional offers. This calculator helps you see through marketing tactics and make data-driven purchasing decisions.
Discount Amount = Original Price × (Discount % ÷ 100)
Final Price = Original Price - Discount Amount
Example: $100 × 25% = $25 discount, $75 final price
Discount % = ((Original Price - Sale Price) ÷ Original Price) × 100
Example: (($100 - $75) ÷ $100) × 100 = 25%
Original Price = Sale Price ÷ (1 - Discount % ÷ 100)
Example: $75 ÷ (1 - 25/100) = $75 ÷ 0.75 = $100
Price After Discount 1 = Original × (1 - Discount1% ÷ 100)
Final Price = Price After Discount 1 × (1 - Discount2% ÷ 100)
Example: $100 × 0.8 × 0.9 = $72 (20% then 10% = 28% total)
Coupon Discount = Subtotal × (Coupon % ÷ 100)
Final Total = Subtotal - Coupon Discount
Final Total = Subtotal - Coupon Amount
Note: Final total cannot be less than $0
