Investment calculation| Excel tool

With the help of the ‘Investment Calculation’ Excel tool you can easily calculate the economic benefit of your investment without much input data. Moreover, the tool enables users to compare two investment alternatives with regard to their economic benefit, and a payment plan shows the cash flow.
