The calculator takes the original price (P) and the discount percentage (D%), calculating the savings amount as Savings = P × (D / 100), and the final price as Final Price = P - Savings. It also shows the exact monetary savings.
Discount Amount = Price × (Discount% / 100) | Final Price = Price - Discount AmountA winter jacket originally priced at $180.00 is offered on clearance with a 25% discount.
Interpretation: You save $45.00 off the original retail ticket, paying $135.00 at checkout before local sales tax.
A store offering '20% off plus an extra 10% coupon' does not give 30% off. It gives 28% off (1 - (0.80 × 0.90)).
In most jurisdictions, sales tax is assessed on the final discounted purchase price, not the original retail sticker.
Multiply the original price by 0.20 to get the discount savings, then subtract that from the original price. Or simply multiply the original price by 0.80.
Apply the first discount to the original price, then apply the second percentage to the discounted subtotal. A 20% + 10% discount equals a total savings of 28%, not 30%.
