The Callan Return Calculator is a program that allows you to quickly and easily compute quarterly or monthly GIPS compliant time-weighted returns based on market values and daily cash flows. While this methodology is not as precise as a daily time-weighted return calculation, it is a close approximation in most cases. The Callan Return Calculator will differ most from the precise daily time-weighted calculation when large cash flows relative to the total amount invested are involved. Smaller cash flows can also be a source of return difference in times of extreme market volatility.
If cash flows are properly dated and monthly ending values are posted in the Return Calculator, the calculation meets GIPS standards, except in certain circumstances. For example, exceptionally large intra-month cash flows (>10% of portfolio market value) require special consideration and cannot be factored into the Return Calculator.
Callan's Return Calculator is a 32-bit Windows program. It will not run on a Macintosh or Linux system, unless a third-party emulator is employed. The reliability or success of running the Return Calculator under these conditions is the responsibility of the user.
