What a 401k match is and why to take it
A 401k match is extra pay your employer puts into your retirement account when you contribute, and you collect all of it only by contributing enough. If your plan matches dollar for dollar up to four percent of salary and you put in two percent, half the match goes unclaimed. Check the vesting rules for when it becomes fully yours.

How to do it
- Ask HR or open the benefits portal and find the plan summary.
- Write down the match rule in one line, for example dollar for dollar up to four percent of pay.
- Set your contribution to at least the percentage needed to collect the full match.
- Find the vesting schedule, which says how long you must stay for the match to be yours to keep.
- Pick investments in the plan, reading the fund descriptions and their yearly fees; the plan's default option is where money goes if you choose nothing.
- Check your next two pay stubs to see your contribution and the employer's match appear.
- Raise your contribution by a point each time you get a raise.
Stop and call a professional if
- You are choosing investments and do not understand the options or fees: ask the plan's help line or a fee-only financial planner.
- You are thinking of withdrawing or borrowing from the account: talk to the plan administrator and a tax professional first.
- The match does not show up on your statements.
Common mistakes
- Waiting until you feel settled in the job before enrolling.
- Contributing below the match level to take home a little more.
- Cashing out the account when you change jobs, which triggers taxes and penalties.
- Never looking at the account after signing up.
