If I've just become disabled due to injury/sickness how much will I receive on a monthly basis from disability insurance?

The amount you will receive when you become disabled varies depending on who is paying the bills.

• Under workers compensation, when an employer pays for a disability that occurs because of an on-the-job-injury, the amount of benefits that are paid out for injuries or illness is usually determined by the severity of the condition that’s suffered, and the disability rating that is provided by the doctor overseeing the case. 
• If you have private disability insurance that covers both long and short term disabilities, the amount that is paid out usually depends on how long your physician has determined you will need to be out of work and the terms of your policy. This is importance in cases in which your employer provides long and short term disability insurance or when you have purchased private insurance. 
• When the application for disability benefits is filed with the Social Security Administration, the amount of the benefits that will be paid out, if any, depends on the determination of your disability. Generally your disability application’s approval will depend on whether or not you are considered disabled, meaning unable to perform any sort of work whatsoever. When your application has been approved, the amount of benefits you will be paid is determined by the amount of income you have generated throughout your working history. Generally, however, the maximum amount of benefits you’ll be paid is typically about 70% of your gross income.
