Frequently Asked Questions
1. What is a realistic expected return for a 401k?
While the S&P 500 has averaged roughly 10% annually, many advisors suggest using 7% to account for inflation and a more conservative bond-heavy mix as you approach retirement.
2. Should I use a Roth or Traditional 401k?
Traditional 401ks give you a tax break today, while Roth 401ks allow for tax-free withdrawals in the future. This calculator works for both, as the principal growth remains the same.
