Actually, that depends on your family's life insurance needs. Usually, an employer provided life insurance plan may offer from one to two times your annual income in life insurance.
So, if you earn $50,000 a year, you may be able to get up to $100,000 of life insurance through your employer.
However, many people may need up to 7-10 times their income in life insurance (or more), depending on their situation.
That's why it's important to understand how much life insurance you really need.
Also, it's a good idea to have your own life insurance policy separate from your job. That way, you can enough life insurance to meet your needs and you won't lose your life insurance protection if you lose your job.
