Understanding Long Term Disability Insurance
Long term disability insurance (LTD) is designed to protect your income when you are unable to work for an extended period due to illness or injury. While short term disability insurance covers temporary issues like minor surgeries or maternity leave, long-term disability insurance kicks in when the illness or injury prevents you from working for months or years.
Typically, LTD policies cover 50-70% of your salary and are offered as group plans through employers or as individual policies purchased independently.
What Is Long Term Disability?
At its core, long-term disability is coverage for the loss of ability to work over an extended period due to medical conditions. Policies often define disability as the inability to perform your “own occupation” or any occupation for which you are reasonably qualified.
According to the Council for Disability Awareness, musculoskeletal disorders are the most common claim, accounting for 29% of all long-term disability cases. Other major categories include mental health disorders, autoimmune diseases, and chronic illnesses.
Why it matters: Long term disability insurance provides financial stability, helping you pay for essentials like mortgage, groceries, and medical bills when you cannot earn a living.
Difference Between Short-Term and Long-Term Disability

Example: A broken leg may qualify for short term disability, while chronic back pain or multiple sclerosis would fall under long term disability.
How Long Does Long-Term Disability Last?
The duration of LTD benefits depends on the policy and medical condition:
- Many policies last until retirement age
- Some cap at 2-5 years for specific conditions
- Mental health claims are often limited to 24 months
- Conditions like multiple sclerosis may qualify for lifelong benefits if the disability persists
- Factors such as age, severity, and occupation also influence the benefit period.
