How much disability insurance do you need?
Most people insure their house and car, but their biggest financial asset is usually their ability to earn a paycheck. Disability insurance protects that income if an illness or injury keeps you from working. Here is how it works and how to work out how much you need, using guidance from the National Association of Insurance Commissioners (NAIC).
Short-term and long-term coverage
- Short-term disability typically replaces part of your pay for a few months. The NAIC describes it as usually covering three to six months.
- Long-term disability generally starts about six months after a disability begins and can last for years, in some policies until retirement age.
Many households need to think about both: short-term coverage for a broken bone or surgery recovery, and long-term coverage for a condition that keeps you out of work far longer.
How much of your income it replaces
According to the NAIC, a typical disability policy pays approximately 60% of your earned income before the disability. That is meant to cover the essentials, not to replace every dollar.
The waiting period
Benefits start after a waiting period, also called the elimination period. The NAIC notes that a 30-day waiting period is common, and that policies with longer waiting periods generally cost less. If you have savings or paid leave to cover the first weeks, a longer waiting period can lower your premium.
What counts as "disabled"
Policies define disability differently. Some pay if you cannot do the duties of your own occupation; others pay only if you cannot do any job you are qualified for. The first is broader and usually costs more. Read the definition before you compare prices.
Working out how much you need
The NAIC suggests starting with the income you need to meet your essential obligations:
- Rent or mortgage
- Food and utilities
- Transportation
- Health care costs, which often go up during a disability
Then subtract what you could rely on: savings, paid leave, a partner's income and any coverage through work. What's left is the gap a disability policy should fill.
Before you buy
- Compare the waiting period, benefit period, definition of disability and maximum benefit side by side.
- Check how pre-existing conditions and pregnancy are treated.
- Confirm with your state insurance department that the agent and company are licensed, as the NAIC recommends.
Federal employees have their own mix of sick leave and FERS disability retirement; see disability insurance for federal employees.
