I have a question about modeling a retirement account. This account is held by one company, and 25% of the total is held in a fund that guarantees around 5%. The remainder is held in a stock fund that fluctuates with various factors. I’d like to enter this such that I can hold the 25% at the constant growth rate, and play “what-if” with the remainder. All funds, as well as new contributions (that are made monthly) are made pre-tax. I’m using the Economics-based planning model. What is/are my best modeling option(s)?
