the effects of good design on sales

now, every factory has realized that a nice appearance can promote the product sales. much more expense than before has been put on the design.

however, in what extent, the design can infulence and enlarge the sales of their goods?

…don’t know of any magic number…i have created designs which improved sales $1-2m in the first year and others which made lesser impacts…sometimes it is more a matter of what you might have lost in sales if you hadn’t spent the design $$$, which is a lot harder to quantify.
