U.S. residents might be more interested in disability insurance if they knew what it really cost.

Researchers at Guardian Life Insurance Company of America, New York, have presented data supporting that argument in a summary of results of a survey of 1,072 U.S. adults ages 18 and older.

About 30% of the participants admitted that they do not have enough disability insurance, the Guardian researchers report.

Although 23% of the participants said they are not willing to pay any amount to protect their incomes, more than 30% said they are prepared to pay more than 10% of their monthly income for disability income protection, the researchers report.

Many of the participants without disability coverage appeared to be unaware that the typical cost is only about 2% of the insured’s income, the researchers report.

In other survey findings:

- 24% of the participants said they never review their disability insurance.

- 54% of the participants said they review their disability insurance at least once a year.

- 75% of the participants said they review their auto insurance at least once a year.
