How much should I contribute to 401k?
At minimum contribute enough to get the full employer match. For a 50% match on 6%: contribute 6% of salary. On an $80000 salary that is $4800/year and employer adds $2400 free. Beyond the match aim for 15% of income for retirement savings including employer contributions.
Should I max out 401k?
If you can afford it yes. Contributing $23500/year at 8% returns from age 30 to 65 grows to approximately $6.7 million. Even if you cannot max out increasing contributions by 1% each year (from 6% to 15% over 9 years) significantly improves retirement outcomes with minimal lifestyle impact.
Traditional vs Roth 401k?
Traditional: tax deduction now taxed in retirement. Roth: no deduction now tax-free in retirement. Choose Roth if you expect higher tax rates in retirement (younger workers early career). Choose Traditional if you are in peak earning years (35-55) and expect lower retirement income. Many advisors recommend splitting between both.
