One of your most important assets is your ability to make a living. There are circumstances in which through illness or injury your ability is incapacitated. In these times you can collect disability insurance to help you through this difficulty. If you are self-employed or your coverage through your employer is nonexistent or inadequate you need this coverage.
Employer-sponsored disability insurance usually pays only a portion of your base salary, up to a cap. It also does not cover bonuses or commissions. Generally, you cannot replace more than 75% of your income from all the coverage combined. Buying your own policy does allow you to customize your options such as cost of living adjustments. In addition, you know you always have your coverage regardless of where you are employed.
