Financial Goals

This Monte Carlo simulation supports planning for financial goals and related spending. Multiple cashflow goals can be applied based on different life stages, and the simulation supports the use of linear glide path to transition from a career stage growth portfolio into a retirement stage income portfolio. The following simulation models are supported for portfolio returns:

Monte Carlo Simulation Results

Monte Carlo simulation results for 10000 portfolios with $500,000 initial portfolio balance using available historical returns data from Jan 1994 to Dec 2017. 24-year linear glide path was used to transition from starting portfolio to retirement portfolio. The simulated inflation model used normal distribution with 3.22% mean and 3.13% standard deviation based on the parameters. The generated inflation samples were uncorrelated with simulated asset returns. The simulation time period was constrained by the available history for Global Bonds (Unhedged) [Jan 1994 - Mar 2018].

Notes on results:
  • Monte Carlo simulation uses historical data and thus assumes that the future will, to some extent, mimic the past. The actual future results may vary.
  • The probability of success is based on the number of simulations the portfolio survives with a positive end balance.
  • Maximum drawdown statistics are calculated from simulated monthly balances.
  • The results assume annual rebalancing of portfolio assets at the end of each year. Taxes and transaction fees are not taken into account.
  • Past performance is not a guarantee of future returns and data and other errors may exist. See Disclaimer and Terms of Use
  • Glide path based portfolio allocation changes are done as part of annual rebalancing
  • Withdrawals are done at the start of each specified time period (fixed amounts before percentage based)
  • Contributions are done at the end of each specified time period
