Updating live: the first X items pay full price; the next Y items pay (1 − discount ÷ 100) of the item price.
For the simple discount, you enter an original price and a percent off. The tool multiplies the price by the percentage divided by 100 to get the discount amount, then subtracts it from the original. For the buy-X-get-Y section, the first X items pay full price and the next Y items pay a reduced price based on the discount percentage. Sales tax is not included — apply your local rate to the sale price separately.
Discounts are applied before tax. Sales tax is calculated on the discounted price, not the original. So a $100 item at 20% off with 8% tax would be $80 + $6.40 tax = $86.40, not $100 + $8 tax − $20 = $88.
This calculator applies a single percentage discount. If stacking (e.g., 20% off then an extra 10% off), the second discount applies to the already-reduced price — 20% then 10% off $100 gives $72, not $70. Run the calculator twice with each discount.
Use the BOGO section: set Buy Quantity to 1, Get Quantity to 1, and Discount to 50%. For a $40 item, you'd pay $40 + $20 = $60 total, or $30 per item — a 25% effective discount on each item.
Stores may round differently (some round up the discount, some round down). Tax calculation order and coupon stacking rules also vary. This calculator rounds to the nearest cent using standard mathematical rounding.
