Frequently Asked Questions

How do I calculate a discount?▼
Multiply the original price by the discount percentage, then subtract that from the price. For example, 20% off $50 saves $10, for a $40 final price.
Can I stack multiple discounts?▼
Stacked discounts apply sequentially, not additively. Two 20% discounts equal 36% off, not 40% off. This calculator applies a single discount.
