401k is an employer-sponsored retirement plan; 403b is an equivalent plan for non-profit organization. If your company participates in a 401k, contribute at least the minimum amount to receive the maximum employer match. The most common match is 50 cents on the dollar up to a certain percent of your salary, such as 3%. For example, if you contribute 6% of your salary, your company matches up to 3%. If you make $50,000 per year and contribute $3,000, your company will contribute $1500.
You fund your 401(k) plan with pretax dollars, meaning your contributions are taken from your paycheck before taxes are deducted. This makes it easier to save money since you don’t even see it. It also lowers your tax bracket because it lowers your taxable income. You pay tax on the contribution and gains when you withdraw. You will not be able to access this money without paying a penalty and tax until you are 59 ½.
Contribute as much as you can as early as you can, preferably before you have a spouse or kids. Once you have a family, it may be difficult to put in the maximum account but you’ll be able to make your retirement account compound nicely if you can have a huge kick-start. Lets say you got a job immediately after your college and put away $19K a year for 5 years then nothing after but invested wisely within the fund. After 35 years with an average of 7% growth, you would have over $1million dollars.
