Percentage off calculator is used to find the sales discount (Percentage off) that is price reduction on the selling price. By using this calculator, we can easily find the sale price of a discounted item after the percentage off discount is applied.

Percentage off can be calculated by using this formula 

Percentage Off = 1 - (Sale Price / Original Price).




Example 1: Find the Percentage off for sale price of an item is $75 and original price is $80

Solution steps:

Given that Sale price = $75

                  Original Price = $80

Percentage off = 1- (75/ 80)

                        = 1- 0.9375

                        =0.0625

Multiply with 100 to represent the 0.0625 in percentage form.

                        = 0.0625 *100

                        = 6.25 %

Answer is 6.25 % off.




Example 2: A gift shop marked a discount of $9 for every purchase worth of $200.Calculate the

percentage off.


Solution steps:

Given that Sale price = original price – discount price

                                    = $200 -$9

                                    =$191

Percentage off = 1- (191/200)

                        = 1- 0.955

                        = 0.045

Multiply with 100 to represent the 0.045 in percentage form.

                        = 0.045 *100

                        = 4.5%

Answer is 4.5% off.
