International Sales Earnings

Let us assume, the Selling Price of a book is $9.80, and the production cost of the book is $2.99. Now, the profits would be calculated as

Profits = [Selling Price – (40% Distribution Cost on Selling Price + Production Cost)] – Processing Fee (37% of the profit amount after deducting distribution cost and production cost)

             = [$9.80 – ($3.92 + $2.99)] – 37%
             = [$9.80 – $6.91] – 37%
             = $2.89 – $1.06 = $1.82

You will earn $2.32 when sold via Amazon.com and other Amazon international websites.

International Expanded Distribution
Let us assume, the Selling Price of a book is $9.80, and the production cost of the book is $2.99 Now, the profits would be calculated as

Profits = [Selling Price – (60% Distribution Cost on Selling Price + Production Cost)]
                 – 37% Processing Fee

                 = [$9.80 – ($5.88 + $2.99)] – 37%
                 = [$9.80 – $8.87] – 37%
                 = $0.93 –$0.34 = $0.58

Through Ingram or expanded distribution, you will earn $0.58.
