Percentage Off Retail Price Calculator
We offer a number of calculators to help shoppers figure out how deep of a discount they are getting and what the final price of an item would be after clearance & sales taxes. The three calculators on this page are:
- Discounted price: subtract a percent from the retail price to obtain the clearance sale price or apply a percent off coupon like the popular 20% off Bed, Bath and Beyond coupons.
- What percent off: use to figure out how deep of a discount you are getting & verify the final pricing matches the claimed discount
- Sales tax: after you have calculated the discounted price, you can use this calculator to figure how much the item will cost after adding in sales tax.
Discounted Price
Y% off of $X = $Z
Discount Amount Formula: (X% / 100) * Y = Z
where
- X = percentage discount
- Y = retail price
- Z = discount amount
Discount Price Forumla: ((100 - X%) / 100) * Y = Z
where
- X = percentage discount
- Y = retail price
- Z = final discounted price
What Percent Of Retail Is This Selling For?
Y is Z% of X
Percent Of Retail Calculation: Y / X * 100 = Z%
where
- Y = sale price
- X = original price
- Z = sale price as a percent of orignal retail price
Example use cases:
- verifying the price charged maches the stated discount
