There is no definitive answer to this question as it can vary significantly based on the type of health insurance plan that a family has. However, according to a recent report from the Kaiser Family Foundation, the average family deductible for health insurance plans offered through employer-sponsored coverage was $1,834 in 2018. This figure has been rising steadily in recent years, and is likely to continue to do so as health care costs continue to increase.
Of course, not all families have employer-sponsored health insurance, and the deductibles for plans obtained through other sources can vary quite a bit. For example, families who purchase their own health insurance through the individual market can expect to pay an average deductible of $5,258, according to the same Kaiser report.
It's also important to keep in mind that deductibles are just one aspect of health insurance costs. Families also have to pay premiums (the monthly cost for their health insurance coverage), and out-of-pocket costs for things like co-pays and coinsurance. So, when considering the cost of health insurance, it's important to look at the whole picture, not just the deductible.
