Annual family premiums for employer health insurance rose 5% to average $20,576 this year, according to a new employer health benefits survey.

The non-profit Kaiser Family Foundation report released Wednesday shows workers on average pay $6,015 toward the cost, while employers pay the rest, or about 71%.

It also shows the average deductible among covered workers in a plan with a general annual deductible is $1,655 for single coverage.

"Despite the nation's strong economy and low unemployment, what employers and workers pay toward premiums continues to rise more quickly than workers' wages and inflation over time," according to a release on the findings.

It says average family premiums have increased 54% over the past decade and workers' contribution have increased 71%. That's well above the 26% increase in wages and 20% increase in inflation over the period, the report notes.

"The single biggest issue in health care for most Americans is that their health costs are growing much faster than their wages are," KFF president and CEO Drew Altman said in a release. "Costs are prohibitive when workers making $25,000 a year have to shell out $7,000 a year just for their share of family premiums."

The report says 56% of small firms and 99% of large firms offer health benefits to at least some of their workers.
