HOWTO: CALCULATE:
Pre Discounted Price
In this example the selling price of the product is £960.00 which was arrived at by discounting the original price by 15%.
To find the original price:
£960 ÷ 85 = 11.29 or 1%.
£11.29 x 100 = £1129 or 100%
£1129.00 is the original price.
Pre-Marked Up (Wholesale) Price
A product retails for £159.90 after a 30% mark-up, what is the wholesale price (price before the mark-up)?
To find the pre-markup price:
£159.90 ÷ 130 = £1.23 or 1%
£1.23 x 100 = £123.00 or 100% (pre-markup price)
