A 401(k) is employer-sponsored with higher contribution limits ($23,000 in 2024). An IRA is individually managed with a $7,000 limit. Both offer tax advantages — traditional accounts defer taxes; Roth accounts are tax-free in retirement.
Always contribute at least enough to capture the full employer match — it's an immediate 50–100% return on investment before any market growth.
If you expect to be in a higher tax bracket in retirement, a Roth 401(k) (paying taxes now) may be advantageous. If you're in a high bracket today, traditional (pre-tax) reduces your current tax bill.
After maxing your 401(k) match, consider a Roth IRA for additional tax-diversified retirement savings. The flexibility of IRA investments often exceeds employer plan options.
Projection uses end-of-year contributions compounded annually. Employer match is applied on contributions up to the match limit.
