4 things to know

Costly mistakes

  • Not getting the full employer match$192,231

    InsteadThat is what half the match grows to by 67 here. Put in at least enough to get the whole match.

  • Cashing out when you change jobs$6,400 on $20k

    InsteadIncome tax plus a 10% penalty before 59½. Do a direct rollover to the new plan or an IRA instead.

  • Paying 1% fees instead of 0.5%$137,892

    InsteadCheck each fund's expense ratio. Broad index funds often charge under 0.10%.

  • Planning in future dollars−60%

    Instead$1,254,932 at 67 buys what $503,312 buys today. Judge every projection in today's dollars.

  • Leaving long-term money in cash−2.9%/yr

    InsteadThat is the average savings account after inflation. Keep an emergency fund there; invest money meant for decades.
