Cost Plus Pricing
The cost plus page allows you to calculate a markup in percentage above your variable costs. This then gives you both the markup amount and the selling price amount.
The page has also been designed to allow you to take off a %, for instance if you were to discount your products.
The target cost page is a different approach to pricing, following a market based strategy. The Market price is the price the market is willing to pay for your product (or you can use competitor prices to do this)
The required margin is the margin you would like to make on the product. This will then give you both the required margin amount, and the target cost.
The target cost is the amount you must be able to product / buy in the product at, to make your required margin whilst maintaining a price the market is willing to pay.
