What this estimate assumes

  • The nominal annual return is divided by 12 and compounded monthly; contributions arrive at month end and do not increase with inflation.
  • Enter a return already net of tax and fees. These deductions are not applied again. The main balance is nominal; today’s-dollar value is separately deflated annually.
  • This constant-return illustration does not model market volatility. Returns are not guaranteed and losses are possible.

For information only, not financial advice. These simplified estimates do not consider your full circumstances. Assumed rates are not forecasts or guaranteed returns. Talk to a financial adviser before making financial decisions.
