How to Calculate a Discount and Final Sale Price

A practical guide to discount percentages, amount saved, final price, and stacked discounts.

Find the discount amount

Multiply the original price by the discount percentage expressed as a decimal. A 25% discount on 8,000 is 8,000 × 0.25 = 2,000.

Find the final price

Subtract the discount amount from the original price. In the example above, 8,000 − 2,000 gives a final price of 6,000.

Stacked discounts are not added together

If a store applies 20% off and then another 20% off, the second discount applies to the reduced price. The total reduction is 36%, not 40%.

Where this is useful

Discount calculations are useful for sale shopping, quotation preparation, promotional campaigns, reseller pricing, and comparing offers.
