How does the return from ee amount and er amount is calculated?

The return from employee (EE) and employer (ER) contributions in a retirement plan is typically calculated based on the investment performance of the fund where these contributions are allocated. The EE amount refers to the portion of the contribution made by the employee, while the ER amount is what the employer contributes on behalf of the employee. Both amounts grow over time through interest, dividends, and capital gains, depending on the investment options chosen. The total return is then determined by the overall growth of the investment portfolio, which is usually expressed as a percentage of the total contributions made.
