When considering the selling price of your book, it is important you take into account all the expenses you may incur producing and promoting it for sale.

Once you have calculated these costs you will be able to work out the minimum number of books you need to sell at a set price to cover your expenses. Any sales above this number represent a profit for you.

If you plan to sell copies to book shops be aware they will expect a substantial discount, often in the region of between 35% and 50%. It is a good idea to research how much similar books are currently selling for in book shops as this will give you an idea as to how much potential readers will be prepared to pay for your book.
