Questions

401k Calculator FAQ

Can I include multiple employer matches or varying contribution rates over time?
The calculator uses a single contribution rate and employer match amount entered by the user; it does not support variable rates or multiple match structures within one simulation.
How does the withdrawal frequency affect the projected balance timeline?
Withdrawal frequency determines how often funds are taken from the account; more frequent withdrawals will deplete the balance faster, while less frequent withdrawals allow the remaining balance to compound for longer periods.
What does the 'Expected rate of return' field represent?
It is the annual percentage return you expect your 401(k) investments to generate; the calculator compounds this rate annually over the time horizon you specify.
Is the final balance shown before or after taxes?
The projected final balance is pre-tax; the withdrawal amounts displayed after the first withdrawal are shown after estimated income tax has been applied.
