How the Discount & Sale Calculator Works
Calculates discounted sale prices, total dollar savings, and optional post-discount sales tax adjustments during shopping sales or merchant promotions.
Formula
Final Price = Original Price × (1 - (Discount% / 100))
Total Savings = Original Price × (Discount% / 100).
Calculation Example
A $120 item marked down by 30% yields a $36 savings, resulting in a final pre-tax price of $84.
Frequently Asked Questions
How do stacked discounts calculate?
Stacked discounts apply successively: a $100 item with 20% off becomes $80, and an additional 10% coupon off $80 equals $72 (a net 28% total discount).
