Video Overview
This lesson addresses what someone might consider when an employer offers a Traditional 401(k) but no Roth 401(k). The speaker builds two scenarios with 2018 contribution limits and tax assumptions. In the first, annual contributions enter a Traditional 401(k); retirement withdrawals follow the video's assumed RMD schedule, income tax is paid, and the remaining funds enter a taxable investment account. In the second, the investor first contributes to a Roth IRA and places the remaining investable amount in a taxable account holding an index for the long term. The video compares the resulting after-tax assets later in life and stresses that the taxable account must have low turnover, because frequent trading would recognize taxes earlier. The illustration does not include employer matching contributions, and its limits, tax rates, RMD age, and eligibility rules are based on 2018 assumptions. It is not current retirement or tax advice.
Key Takeaways
- The video compares the modeled after-tax result of a Traditional 401(k) with a Roth IRA plus a taxable investment account.
- The Traditional-account scenario includes retirement income tax, RMDs, and capital gains tax after withdrawals move into a taxable account.
- The Roth-plus-taxable scenario first accounts for taxes during the working years and then allocates funds between the two accounts.
- The taxable-account comparison depends on a long-term, low-turnover index assumption; frequent trading would change its tax outcome.
- Employer matching, current contribution limits, personal tax rates, and eligibility rules may materially change the comparison.
