Discount calculator.
Know your savings.

Yes. Personal shopping supports up to 50 items. Each item has its own unit price, quantity, optional name, note, and discount percentage. Item discounts are applied first. Optional order discounts then apply to the combined discounted item subtotals, and extra fees are added once. New calculations start with no order discount. Each item subtotal is rounded to the selected currency’s smallest supported unit, followed by one rounding step for order discounts.

Choose Group order and enter each person’s spending before discount. Equal split gives everyone the same discount, capped at their spending. Proportional split allocates the discount according to each person’s share of the original subtotal. For example, spending of USD 50, 25, and 25 with a USD 30 discount gives proportional savings of USD 15, 7.50, and 7.50. Shared fees can use a separate splitting method.

Price after discount = original price × (1 − discount / 100). For example, USD 250 with a 20% discount becomes USD 200. Enter the unit price, discount, and quantity to calculate your total. Extra fees are added once at the end.

No. The second discount applies to the price after the first discount. A 20% discount followed by 10% is an effective discount of 28%. USD 100 becomes USD 80, then USD 72. Stacked order discounts are applied after any individual item discounts, with the order discount result rounded once to the selected currency’s smallest supported unit.

Yes. Choose a currency in either calculator. The selection controls formatting and rounding, and is saved with your history and share links. USD, EUR, and most supported currencies use two decimal places; KWD uses three. IDR, JPY, and KRW use whole units in this calculator. Switching currencies keeps the numbers you entered and does not convert exchange rates.

Your inputs and up to 50 saved calculations stay in this browser on this device. Details shows the information and payment status recorded when a calculation was saved. You can copy or delete an individual record. Later changes to the form do not update old history automatically. Clearing site data removes history, and data does not sync between devices. Private browsing may remove data when the session ends.

Use Share to create a compressed link containing the current calculation, currency, and payment status. Anyone with the link can read its contents; compression is not encryption. The link is a snapshot, so later changes do not sync. Your other saved calculations are not included.
