Growth value
Growth value is the growth of your portfolio, represented as a monetary value, since you opened a Prosper account.
To work this out, we subtract the initial value of your portfolio when you opened the account from its current value. And we subtract the value of any transactions such as fees, deposits or withdrawals.

Growth percentage
Growth percentage is the growth of your portfolio, represented as a percentage, since you opened a ForMore account.
To work this out, we use the Modified Dietz Method, sometimes called the modified internal rate of return (MIRR).
This method is an industry-standard approach to accurately report returns. It takes into account the timing and amount of cash flows during an investment period, which results in a more reliable calculation.
