Frequently Asked Questions

Does this account for taxes?

No, this simulator does not factor in taxes on withdrawals. Consider consulting a tax professional for after-tax projections.

What happens if my balance reaches zero?

The simulator stops reducing the balance below zero and records the year your funds would run out based on your inputs.

How does inflation affect withdrawals?

Your annual withdrawal amount increases each year by the inflation rate to maintain purchasing power, which is subtracted before investment growth is applied.
