What Is the Percent Off Calculator?
This tool tells you the discount percentage between an item original (regular) price and its lower sale price. Instead of guessing whether a deal is good, you get the exact percent off and the dollar (or any currency) amount you saved. It works for shopping, retail markdowns, coupons, and comparing offers.
How to Use It
Enter the original price and the sale price, then read the result. The calculator shows the percent off as the main number, plus a breakdown of the original price, sale price, and the amount you saved. Both prices use the same currency, so the result is currency-independent.
The Formula Explained
The percent off is the difference between the two prices divided by the original price, multiplied by 100:
$$\text{Percent Off} = \frac{\text{Original} - \text{Sale}}{\text{Original}} \times 100$$
Subtracting gives the amount saved. Dividing by the original price expresses that saving as a fraction of what you would have paid, and multiplying by 100 turns it into a percentage.
Worked Example
Suppose an item normally costs 100 and is on sale for 75. The amount saved is \(100 - 75 = 25\). The percent off is $$25 \div 100 \times 100 = 25\%$$ So the item is 25% off and you save 25.
FAQ
Is percent off the same as the new price? No. Percent off is how much the price was reduced. A 25% off item still costs 75% of the original.
What if the sale price is higher than the original? The result becomes negative, indicating a price increase rather than a discount.
Can I use any currency? Yes. The percentage is the same regardless of currency since both prices cancel out in the ratio.
