Which Health Plan Is Cheaper?

Doing a thorough comparison of health care plans is difficult. But there is an imperfect, yet fairly, simple way to check whether a high-deductible plan might qualify for “no-brainer” status, meaning, it enables you to save on health care no matter how often you go to the doctor.

Here’s how to do it:

Start with your premiums

Figure out how much you would have to pay in total annual premiums for low- and high-deductible plans.

Do this by multiplying the cost of the plan per paycheck by the number of paychecks you get per year: 12 if paid monthly, 26 if biweekly, 52 if weekly.

Do a zero-expense test

Then turn to the high-deductible plan.

If your employer contributes to a Health Savings Account for you, subtract that amount — say, $1,000 — from the cost of the premiums.

Compare the result for the two plans.

The high-deductible plan is bound to be cheaper.

The difference is how much you would save if you have zero health care expenses.

Clear the high-deductible hurdle

Next, try a test that is more difficult for high-deductible health plans: Consider what happens if your expenses are exactly equal to the deductible for each plan.

For example, say the low-deductible plan has an annual premium of $3,650 and a deductible of $1,000.

You’d pay $4,650 if your bills equal the amount of the deductible.

By comparison, the high-deductible plan has an annual premium of $2,000 and a deductible of $3,250.

You would spend $5,250 if you hit the deductible, except for one important thing: Your employer contributes $1,000 to your H.S.A., so your total costs only come to $4,250.

That is $400 less than the amount for the low-deductible plan.

So far, in this case, the high-deductible plan is a “no-brainer.”

Do it all again

Finally, repeat these steps, using the maximum-out-of-pocket limit for each plan in place of the deductible.

If the high-deductible plan is still cheaper, it may be a “no-brainer.

That’s it. You’re done with the simple test.

A note of caution

Remember, these calculations are not perfect because there are complicating factors, such as how prescription drugs are covered in the two plans.

Still, this is a good starting place for your comparisons. Your employer’s website may provide a plan comparison tool.

See what it says. But, most important, consider your options instead of automatically taking a version of last year’s plan.
