What is a 401(k) and how does it work?
Name ____________________ Date __________
Key ideas
- Money goes in before you see it. You choose a percentage of pay. Your employer moves it into the account each payday, so saving takes no willpower.
- A traditional 401(k) lowers your tax today. In the example, Sam puts in $100 a paycheck but his take-home drops only $88, because he pays $12 less federal tax.
- The account is for after age 59½. Early withdrawals usually cost income tax plus a 10% extra tax. Money you put in stays yours when you change jobs.

Answer key
What is a 401(k) and how does it work?
Work it out
- 401(k), 5% of $2,000$100
- Federal tax saved at 12%− $12
- Drop in take-home pay= $88
- Paychecks a year26
- Into the 401(k) a year$2,600
- Federal tax saved a year− $312
- Cost to Sam's take-home= $2,288
- Each paycheck, $2,000 × 5% = $100 goes into Sam's 401(k) before federal income tax is figured.
- That lowers his federal tax by $100 × 12% = $12, so his take-home drops by only $100 − $12 = $88.
- Over 26 paychecks he saves $100 × 26 = $2,600 and pays $12 × 26 = $312 less federal tax. State tax savings, if any, are extra.
