Did You Know?
How Does Percentage Discount Work?
Basic Formula
Discount Amount = Original Price × (Discount% ÷ 100). Sale Price = Original - Discount. Example: $80 × 25% = $20 off, sale price $60.
Stacked Discounts
Apply each discount to the result of the previous. $100 with 20% then 10%: $100 × 0.80 = $80, then $80 × 0.90 = $72. Total savings 28%.
Tax and Quantity
Tax applies to the discounted subtotal. Quantity multiplies the unit price before discounts. Final = (Original × Qty × discount factors) × (1 + Tax%).

Frequently Asked Questions
How do I calculate a percentage discount?
Discount Amount = Original Price × (Discount% / 100). Sale Price = Original - Discount. A 25% discount on $80 saves $20, making the sale price $60.
How do stacked discounts work?
Stacked discounts are applied sequentially, not added. A 20% then 10% discount is NOT 30%. It's: $100 × 0.80 = $80, then $80 × 0.90 = $72. Total savings: 28%, not 30%.
How do I calculate the original price from a sale price?
Original = Sale Price / (1 - Discount%/100). If an item is $60 after 25% off: $60 / 0.75 = $80 original price.
Is a bigger discount always better?
Not necessarily. Compare final prices. A $50 item at 30% off ($35) is cheaper than a $40 item at 10% off ($36), even though the second discount percentage is lower.
How does sales tax affect discounted prices?
Tax is calculated on the discounted price, not the original. A $100 item at 20% off with 8% tax: $80 × 1.08 = $86.40, saving you $21.60 vs full price with tax.
What is the difference between markup and discount?
Markup is added to cost price to set selling price. Discount is subtracted from selling price. A 50% markup on $100 = $150, but a 50% discount on $150 = $75, not $100.
