**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)
