There is another percentage measure to assess the success for a Book Printing job. The return on investment (ROI) line in the estimate shows the ratio of money gained, expressed as a percentage, on investment in the book for the first and second printings over the given time periods, and over the three-year view. For instance, if a publisher invested 10,000 in a book and got back 15,000 in revenue, the ROI would be 50 per cent. This is calculated by expressing the profit of 5,000 as a percentage of the investment.
For the book of Inside Book Publishing, on the first printing, the investment is the direct variable costs of 7,862 and the direct overheads of 8,798. These total 16,660. The NSR is 18,166 from which is deducted the total costs of 16,660.
