About Average Return Calculator

The Average Return Calculator helps investors determine the annualized return of their investments, accounting for cash flows (deposits and withdrawals) over time. This provides a more accurate picture of investment performance than simple return calculations.

How to Calculate Average Return

There are two main methods for calculating average returns:

1. Cash Flow Based Calculation

This method calculates the internal rate of return (IRR) considering:

  1. The starting balance and date
  2. All deposits and withdrawals with their dates
  3. The ending balance and date

The calculator uses an iterative process to find the rate that equates the present value of all cash flows to zero.

2. Holding Period Based Calculation

This method calculates the geometric mean return for multiple holding periods:

  1. Enter each period's return percentage
  2. Specify the duration (years and months) for each period
  3. The calculator computes the compounded annual growth rate (CAGR)
