How to use this estimate

Enter a planning assumption, not a promise. The model compounds monthly and adds deposits at the end of each month. Real investments fluctuate, and fees, taxes, inflation, withdrawals, and changing contributions can materially alter the outcome.

FAQ

What return should I enter?: Use a range of conservative, expected, and optimistic scenarios rather than one number. Diversification and time horizon affect risk, and past performance does not guarantee future returns.
Does this include investment fees?: No. To approximate a fee drag, reduce the annual return assumption by the expected annual fee, while remembering that fees may be charged differently.
