Do I need to create an account to use the calculator?

No, the tool is free to use and does not require registration or login.

Can I import my actual portfolio holdings from a brokerage?

No, the calculator relies on manual entry of expected return and volatility figures for each asset class.

What does the efficient frontier show?

It displays the set of optimal portfolios that offer the highest expected return for a defined level of risk, helping you identify allocations that balance risk and reward according to Modern Portfolio Theory.

How reliable are the Monte Carlo simulation results?

The simulations generate a range of possible outcomes based on the input volatility and return assumptions; they are illustrative rather than predictive of actual market behavior.
