Simple Dietz

Welcome to Simple Dietz Performance Screen

We have improved Simple Fund 360 Investment Reporting for Planners and Investment advisers by adding a new Simple Dietz Method to the Investment Dashboard. The new method provides a more weighted measure when calculating the return on a portfolio than a simple return method.

The Simple Dietz method measures investment performance during a period, incorporating cash inflows and outflows.

The Simple Dietz method is named after Peter O. Dietz, author of 'Pension Funds: Measuring Investment Performance'.

Assume NCFt1 occurs at the beginning of t1 and NCFt2 occurs at the end of t2 and other cash flows occur at the mid-point of (t1, t2) on average.

 Ii Income on a specific day i

The income amount is the amount of cash flow from the income received including any tax credits associated with the income.
