Discount Calculator
Is that sale actually a deal? Enter the list price and discount to see the sale price, your savings, and the final total after sales tax.
A percentage discount removes that fraction of the original price: 25% off means you pay 75%. The discount is always taken off the list price first — never off the taxed total.
Sales tax is then applied to the discounted price, which is how US registers calculate it. Note that stacked discounts multiply rather than add: 20% off then 10% off leaves 0.8 × 0.9 = 72% of the price — a 28% total discount, not 30%.
Worked examples
Everyday sale
$89.99 jacket at 25% off with 7% sales tax.
→ $72.22 final — save $22.50
Half price
50% off a $40 item: you pay $20 before tax and save $20.
→ $20.00
Stacked coupons
20% off plus an extra 10% off a $100 item: $100 × 0.8 × 0.9.
→ $72.00 (28% off, not 30%)
