Income protection is important since illness or injury could prevent working and reduce income, yet people rarely consider this risk. Disability insurance provides monthly benefits if unable to work due to sickness or injury, replacing part of lost income. While the average car costs around $30,000, the average disability claim lasts 4 years, with illness being the leading cause. Disability insurance is more affordable than many other regular expenses and helps reduce the risk of a disability leaving one unable to pay living expenses.
