Secure checkout. Your download link is sent as soon as payment clears.

Before you spend serious money on a new machine, a shop, a vehicle fleet or an energy project, you need to know whether it will earn more than the money costs you – and how sure you can be. This workbook turns your forecasts into year-by-year cash flows after tax, works out every standard investment measure, shows how far your forecasts could be wrong before the project stops paying, and compares up to three projects side by side.
