How to use the discount calculator

It updates the moment you type — no button to press. To find a sale price:

1
Enter the original price — the full price before any discount, as shown on the tag.
2
Set the discount — drag the slider or tap a preset like 25% or 50% off.
3
Choose a quantity — buying more than one? Bump the count to see the total saving.
4
Read the result — the price you pay, how much you save, and the price per item — instantly.

How to calculate a discount manually

A discount is a percentage taken off the original price. Convert the percent to a decimal, multiply to get the saving, then subtract:

Saving = Price × (Percent ÷ 100)
Sale price = Price − Saving

Worked example. A $80 jacket at 25% off:

Saving — $80 × (25 ÷ 100)$20.00
Sale price — $80 − $20$60.00

Mental shortcut: 25% off means you pay three-quarters of the price. For 50% off, simply halve it.

Do stacked discounts add up?

No — and this trips people up. “50% off, then an extra 20% off” is not 70% off. The second discount applies to the already-reduced price, so the percentages multiply rather than add:

50% off, then 20% off
0.50 × 0.80 of price
60% off
30% off, then 10% off
0.70 × 0.90 of price
37% off
20% off, then 20% off
0.80 × 0.80 of price
36% off

Frequently asked questions

Multiply the price by the discount percent divided by 100 to get the saving, then subtract it from the price. For example, 25% off $80 is $80 × 0.25 = $20 saved, so you pay $60.
