A discount lowers the original price by a percentage. From the original price and the discount rate this calculator shows two figures: the final price you actually pay, and the savings, that is the amount the discount takes off. So when shopping, in a sale or with an offer you see at a glance what is left at the end and how much the reduction really gives you.
The calculation runs entirely locally in your browser, in pure JavaScript - nothing is uploaded and nothing is stored. The final price is the original price times one minus the discount rate, and the savings are the difference between the two. The discount is limited to 0 to 100 percent. Change the price or the discount and the final price and savings update instantly.
An honest note: this is plain percentage arithmetic on a single price. Stacked discounts applied one after another, quantity tiers or value-added tax are not modelled automatically - the VAT calculator handles tax. The amounts are shown in euros as an example; the maths applies to any currency.

Final price = original price times (one minus the discount rate). The savings are the difference between the original and final price.
The calculator applies one discount to one price. For stacked discounts, apply them one after another: enter the result again as the original price.
The calculator only handles the discount. For net/gross and tax, use the VAT calculator.
