What Is a Percent Off Calculator?
A percent off (or discount) calculator tells you the final price you will pay after a percentage discount is applied, plus how much money you save. It is perfect for sales, coupons, clearance tags, and "25% off" promotions where you want the exact dollar figure before reaching the checkout.
How to Use It
Enter the original price of the item and the discount percentage advertised. The calculator instantly returns the amount you save and the final sale price. Works with any currency — just read the result in your own units.
The Formula Explained
The savings equal the price multiplied by the discount fraction: \(\text{Saved} = \text{Price} \times \frac{\text{Discount (\%)}}{100}\). The final price is simply the original price minus the savings, which can be written compactly as \(\text{Final} = \text{Price} \times \left(1 - \frac{\text{Discount (\%)}}{100}\right)\). A 100% discount makes the item free; a 0% discount leaves the price unchanged.
$$\text{Sale Price} = \text{Original Price} \times \left(1 - \frac{\text{Discount (\%)}}{100}\right)$$
Worked Example
Suppose a jacket costs $80 and is marked 25% off. The savings are $$80 \times \frac{25}{100} = \$20.$$ The final price is $$80 - 20 = \$60.$$ So you pay $60 and save $20.
FAQ
Does this include sales tax? No. The result is the pre-tax discounted price. Add any applicable tax separately.
Can I stack two discounts? Stacked discounts multiply, not add. Apply the first discount, then run the result through the calculator again with the second percentage.
What does "you save" mean? It is the dollar amount removed from the original price — the difference between what you would have paid and what you actually pay.
