Frequently Asked Questions
How do I calculate a percentage discount?
Discounted Price = Original Price × (1 - Discount%/100). A 25% discount on $80: $80 × 0.75 = $60. You save $20. The calculator shows the final price, savings amount, and effective discount percentage.
How do I calculate the original price before a discount?
Original Price = Sale Price ÷ (1 - Discount%/100). If an item is $60 after 25% off: $60 ÷ 0.75 = $80 original price. The calculator can reverse-calculate the original price from the discounted price.
How do stacked discounts work?
Stacked discounts are applied sequentially, not added. 20% off then 10% off is NOT 30% off. $100 × 0.80 = $80, then $80 × 0.90 = $72. Total discount is 28%, not 30%. The calculator handles multiple sequential discounts.
How do I calculate discount per unit for bulk orders?
Divide total discount by quantity. If 100 units at $10 each get 15% off: total = $1,000 × 0.85 = $850. Per unit: $8.50 (saving $1.50 each). The calculator computes bulk pricing with tiered discount structures.
What is the difference between percentage off and dollars off?
Percentage off scales with price: 20% off $50 = $10, 20% off $200 = $40. Dollars off is fixed: $10 off regardless of price. For expensive items, percentage discounts save more. The calculator compares both methods.
