(CNN) -- Nine of 10 American workers are losing sleep over financial worries, according to a survey released Monday by a company that helps workers deal with wellness issues.

Keeping up with the rising cost of living and credit card debt were top concerns preventing people from falling asleep, according to the results from ComPsych Corporation, which surveyed employees of companies it serves. Thirty percent of respondents reported worrying about the cost of living while 29 percent cited credit-card debt.

Making mortgage payments and building retirement accounts also kept people awake, with 14 percent and 13 percent, respectively, listing those as their main concerns, the survey said.

How to afford childrens' school tuition and health care costs robbed just three percent of sleep, the survey said.

Only eight percent of respondents said they are not worried and have no trouble sleeping.

The study was compiled and released by ComPsych Corporation, which contracts with companies to provide employee assistance programs.

"As the largest EAP, our increased call volume has been a reflection of the financial stressors faced by U.S. employees," said Richard Chaifetz, ComPsych's chief executive officer.
