I’ve just discovered a very handy and user-friendly Obamacare premium calculator. You can calculate your premiums based on California residency or using a general “National” calculator. Of course, premiums will vary by state.
The calculator is VERY easy to use, and I encourage you try both the CA and National calculators and enter several different income and age values. You can estimate what your premiums will look like as you age, if you get married or have children, or if your income fluctuates. You can also estimate what your friends and neighbors might pay, if you are curious!
