Disability insurance is designed to replace a portion of your income if an eligible illness or injury prevents you from working, subject to the specific policy. It is sometimes called income protection, and for many households it matters as much as life insurance.
This article explains what disability insurance generally is and its key features. Nothing here guarantees coverage or benefits. What is covered always depends on the specific policy and insurer.
The purpose
The purpose of disability insurance is to help protect your income. Your income is what makes everything else possible: your home, your family's routine, your plans. If an illness or injury stopped you from working, a portion of your income could continue, subject to the policy, which is what the product is designed to do.
It is different from life insurance, which protects your family if you pass away, and from critical illness insurance, which pays a lump sum for a covered diagnosis. You can see how the products differ for the broader picture.
Replacing a portion of income
Disability insurance generally replaces a portion of your income, not all of it. The percentage and the maximum amount are set out in the policy. Replacing a portion rather than the full amount is typical and is part of how the product is designed.
Inability to work
The benefit is tied to an inability to work, but what "unable to work" means depends on the policy's definition of disability, which is one of the most important features to understand.
Benefit periods
The benefit period is how long benefits may be paid. Some policies pay for a set period, such as two years or five years. Others may pay to a certain age, such as 65. The benefit period affects how the coverage works for you and is set out in the policy.
Waiting and elimination periods
Most policies include a waiting period, sometimes called an elimination period, before benefits begin. It is the time you must be disabled before benefits start. Common waiting periods range from 30 to 180 days. A longer waiting period generally means a lower premium, and a shorter one generally means a higher premium.
Definitions of disability
How a policy defines disability is one of the most important features. Some policies define disability based on your own occupation, meaning you are disabled if you cannot do your own job. Others define it based on any occupation, meaning you are disabled only if you cannot do any job. Some shift from own to any occupation after a period of time.
This difference matters a great deal, because it shapes when and whether benefits are paid. You can read more about how disability insurance works for the details.
Policy differences
Disability insurance is not one product. Coverage, exclusions, definitions, benefit periods, and waiting periods can differ significantly between policies and insurers. There is no single standard policy, which is why understanding the specific product matters.
