I just started working for company, and this is my first time doing anything with a 401(k) plan. I found out this from the brochure, and I am a little confused:

1) you can save up to 80% of your eligible pay before taxes are deducted. By 'eligible pay', do they mean the $17500 limit by the IRS for 2013, or is it something else?
2) ( Up to 6% = 100% match on up to 5% of pay + 1% automatic contribution) after you have completed one year of service. What does this mean?? Can someone give an example?

Any explanation is appreciated!

    All of the answers below are good but I wanted to comment that you have a pretty good company match, there.

  • I see, I have no clue about how other companies are doing it. But it is good to know! Thanks.

  1. Up to 80% of your gross income, per pay period. Annually, still subject to the $17,500 limit. So if your gross salary is $48,000/year, and you get paid twice a month, your gross per pay period would be $2,000 and you would be able to contribute up to $1600 per pay period to your 401K.

  2. The first 5% of your pay you contribute will be matched by the employer. They will match dollar for dollar ("100%"). Some companies match at lower percentages (e.g. fifty cents on the dollar, or 50%). So if you chose to contribute 5% per pay period ($100), your employer would match it dollar per dollar ($100). It sounds like an extra 1% ($20) is automatic.

Matching contributions are sometimes subject to vesting.

Make SURE you take advantage of #2 after you are employed for a year. It's "free money" (really a form of compensation).


I'm not sure if you can contribute more than 80% in a single pay period if you are catching up from not contributing earlier in the year. So the "per pay period" qualification above may not be accurate.

    Two additional thoughts - once you hit the annual limit they will no longer be match you up to 5% amount, because there is nothing left to contribute. - it is not clear if the matching doesn't start for a year, or if the automatic 1% only happens after the first year. It depends on the accuracy of the quote. Nov 11, 2013 at 3:12
  • I was guessing it was the former, as I have has that same restriction with a former employer. However, it is indeed ambiguous as you noted. Nov 11, 2013 at 3:15
  • Thanks for the explanation. So if I make some choices now, can I change it next year? Is it like the insurance(medical, dental, vision) where I can update or change my choices every year in a certain month?

    You can contribute up to 80% in a paycheck. Assume somebody makes %21,875 per year. They have to be able to contribute 80% to get to the $17,500 limit. Hard to be able to do, but it is possible if they want to maximize the contribution for one spouse. Nov 11, 2013 at 3:17
  • It depends on your employer, but with my past employers I was able to change it as often as I wanted (within reason). Some employers allow changes via an automated system (e.g. fidelity.com). Nov 11, 2013 at 3:17

You make $20000. You can put $16,000 in the 401(k).

You make $100,000. Your deposits are $80K/yr or $1600/week, so you hit the $17,500 maximum very early in the year.

Every dollar you put in is matched, up to 6% of your income. On $100K, the first $6000 you put in is matched. If you put 8% in, you'll only see the first 6% matched.
