FAQ
How do I calculate a discount?
Multiply the original price by the discount percentage divided by 100 to get the discount amount, then subtract that from the original price to get the sale price. This calculator does that automatically.
Does the tax field apply before or after the discount?
Tax is applied to the price after the discount, which matches how most retail checkouts calculate sales tax on a discounted item.
Can I use this for stacked or multiple discounts?
This calculator applies a single discount percentage. For stacked discounts, calculate the first discount, then use the resulting price as the new 'original price' for the second discount.
Is my pricing data stored anywhere?
No. All calculations happen locally in your browser — nothing is sent to a server or stored.
