Why you need disability insurance:

The chance of missing months or years of work because of an injury or illness may seem remote, especially if you're young and healthy and you work at a desk.

But more than one in four 20-year-olds will experience a disability for 90 days or more before they reach 67, according to the Social Security Administration.

Your most valuable asset isn't your house, car or retirement account. It's the ability to make a living.

Disability insurance pays a portion of your income if you can't work for an extended period because of an illness or injury.

Types of disability insurance:

There are two main types of disability insurance — short-term and long-term coverage. Both replace a portion of your monthly base salary up to a cap. Some long-term policies pay for additional services, such as training to return to the workforce.
