Breaking down the data further, some products are far outpacing others. Here are the top five voluntary products, by sales, according to Eastbridge data.

The data comes from Eastbridge’s annual U.S. Worksite/Voluntary Sales Report, which analyzes data from more than 60 carriers.

5. Hospital indemnity/supplemental medical

Percentage of total voluntary sales in 2013: 8 percent

Hospital indemnity/supplemental medical sales saw a decrease in 2013, but they were still strong enough to be the fifth best-selling product. Total sales were about $552 million.

Brokers say the Patient Protection and Affordable Care Act is creating big opportunities for them to sell supplemental plans, not only to help cover increasing deductibles in employer-based and exchange-based plans, but also as a cheaper alternative to both.
