Insurance is supposed to protect your finances—not drain them. Yet in 2026, millions of Americans continue to lose thousands of dollars every year due to avoidable insurance mistakes.
Rising premiums, complex policies, and rapidly changing insurance markets (health, auto, home, life) make it easier than ever to overpay or remain underinsured. Whether you live in the U.S. or manage American-based assets, understanding the most costly insurance mistakes Americans make in 2026 is critical.
In this guide, we reveal the 7 biggest insurance errors, why they’re dangerous, and exactly how to avoid them.
