__Time
Weighted Rate of Interest__

**If you want to
calculate the time weighted rate of interest return, use this
calculator. The calculator is setup to handle a 2 event year based on
asset values. The formula for this is:**

**[(AV2/AV1) * (AV3/(AV2 + C1 - W1)) * (AV4/(AV3 + C2 - W2))] - 1**

**Example:
You are given an asset worth 100,000 on January 1. On March 1, the value
has increased to 112,000. Immediately after, a 30,000 contribution is
made. On August 1, the value of the fund is 125,000. Immediately
after, 42,000 is withdrawn. January 1 of the following year, the asset is
valued at 100,000. Calculate the time weighted value of interest.**

**You
would enter the following in the calculator:**

**Enter
Asset Value 1 = 100,000**

**Enter
Contribution Value 1 = 30,000**

**Enter
Withdrawal Value 1 = 0**

**Enter
Asset Value 2 = 112,000**

**Enter
Contribution Value 2 = 0**

**Enter
Withdrawal Value 2 = 42,000**

**Enter
Asset Value 3 = 125,000**

**Enter
Asset Value 4 = 100,000**

**Press
Calculate and your answer is 18.78%**
