### 9 responses to How to Calculate Personal Rate of Return (Time-Weighted Rate of Return)

1. I would be interested in seeing your excel spreadsheet.

I’ve seen two ways to calculate rate of return. The first is from the Association of Investment Management and Research (AIMR) in Charlottesville, Virginia. Their calculation is :

Monthly Return = (EB â€“ Â½C + Â½W) / (BB + Â½ C â€“ Â½W)

where BB is beginning balance, EB is ending balance. C is contribution during the period and W is withdrawal in the period.

The other, which I think may be better, uses the XIRR function in Excel. I think it is better since it allows contributions/withdrawals that are more time dependent within the period being measured. It takes an annualized value (provided by XIRR) and converts it to a given period value. The formula is:

((XIIR result)+1)^((Ending date – Starting Date)/365)-1

^ is power of in Excel. Ending date – Starting Date gives you the number of days being used in the measurement.
