Time-Weighted Return Calculator

This page calculates the Time-Weighted Return for an investment given the investment valuation, and any deposits and withdrawals, on a series of dates.

Initial Value

Valuations

The Time-Weighted Return Calculator is used to calculate the Time-Weighted Return of an investment, given the investment valuation, and any deposits and withdrawals, on a series of dates

Initial Value

Date - Use this field to enter the start date of the investment.

Valuation - This is the value of the investment on the start date. This value must be a positive amount.

Valuations

Every time there was a deposit or withdrawal requires a valuation.

Date - Use this field to enter the date of the valuation.

Total Deposits - This is the value of any deposits made into the investment on this date. Deposits are typically one-off or regular payments you make into the investment. This value can be left empty or set to 0 if no deposit was made, otherwise it must be a positive amount

Total Withdrawals - This is the value of any withdrawals taken from the investment on this date. Withdrawals may include fees that are deducted from the value of the investment or money you take out of the investment yourself. This value can be left empty or set to 0 if no withdrawal was made, otherwise it must be a positive amount

Valuation - This is the value of the investment on the specified date. This value must be a positive amount. If there are transactions (deposits and/or withdrawals) on this date, then the valuation entered should be the valuation after all the transactions. For example, if an investment is worth 100000 and a deposit of 20000 is made, the valuation entered should be 120000.

When entering values, you can use whatever currency you like, as long as both values are in the same currency. You don't need to use a currency symbol such as $ or £ (and doing so will cause an error).

Click the + button to add another period. Another set of fields will appear on the form to allow you to enter another valuation.
