Discount Calculator

The Discount Calculator shows how much you save and what you actually pay when an item is on sale. Enter the original price and the discount percentage, and it returns the discount amount and the final sale price.

What Is the Discount Calculator?

The Discount Calculator applies a percentage discount to a price. If an item costs $120 and is 25% off, the discount is $30 and the sale price is $90. The calculator can also work backwards: given the original and sale prices, it finds the discount percentage. It is useful for shopping, pricing products, and checking sale labels.

How to Use the Discount Calculator

1. Enter the original price, for example 120.
2. Enter the discount percentage, for example 25.
3. Click Calculate or Process to see the result.
4. Read the discount amount and the final price you will pay.
5. To check a sale label instead, enter the original price and the sale price to find the discount percentage.
6. Use Copy to copy the result, or Clear to start a new calculation.

Worked Example

Example: original price $200, discount 30%. The discount amount is 200 x 0.30 = $60. The final price is 200 – 60 = $140. Reverse example: original $200, sale price $140. The saving is 200 – 140 = $60, and the discount percentage is 60 / 200 x 100 = 30%.

Limitations

• The result is the discounted price before tax, shipping, or other fees, unless you add those separately.
• It applies a single percentage discount; stacked discounts or fixed-amount coupons need separate steps.
• Results are rounded to two decimal places for currency, so very small fractions of a cent are rounded.
• It does not check whether a sale price is a genuine bargain compared with other sellers.

Frequently Asked Questions

How do I calculate 20% off $80?

The discount is 80 x 0.20 = $16, so the final price is 80 – 16 = $64.

Can I find the discount percentage from two prices?

Yes. Subtract the sale price from the original price, divide by the original price, and multiply by 100. For $200 down to $140, that is 30%.

Does the calculator include tax?

No. It calculates the discounted price before tax. Add tax separately based on your local rate.

What if there are two discounts, such as 20% then 10%?

Apply them one at a time, not by adding them. A 20% discount followed by 10% off is not 30% off: $100 becomes $80, then $72.
