There is no definitive answer to this question as health insurance costs can vary greatly depending on a number of factors, such as the insurer, the policyholder's age and health status, and the coverage level. However, according to a recent report from eHealth, the average monthly cost of health insurance in Texas is $574. This is slightly higher than the national average of $571. Factors that can impact the cost of health insurance in Texas include the state's high rate of uninsurance, which drives up premiums, and its large rural population, which can make it difficult and expensive to provide health care.
