P/L Calendar shows your returns and yields in the form of a calendar. You can choose to show them on a monthly or yearly basis. You can also filter your historical returns and yields by month and year. How these yields are calculated depends on your settings in P/L Trend, where you can choose from Simple Dietz Method (Simple), Modified Dietz Method (Money-Weighted or MWR), or Time-Weighted Return Method (Time-Weighted or TWR).
Formulas:
1) Return for Day T = Net Assets as of Day T – Net Assets as of Day (T-1) – Net Inflows for Day T
2) Monthly Return = Sum of Daily Returns for the Month
