This Trick Could Save You $4,000 on Health Insurance

Health plan costs have so skyrocketed that even a plan for a single individual can now exceed $1,000 a month. But a new trick, described here for the first time, could save you a bundle.

MrConsumer has long believed that pricing of health insurance is a mathematical game. If a plan has a seemingly low monthly premium, the insurer makes it back by imposing a deductible and higher copays. But a plan with lower copays and no deductible certainly comes with a higher monthly price tag. I am sure the insurers’ actuaries and accountants stay up late at night juggling these variables so that the house wins most of the time.

But it may be possible, though rare, to save thousands of dollars by doing a calculation no one ever suggested you do — find a plan where the health insurance bean counters messed up the mathematical structure of the plan.

So how can you save money when choosing among plans? It certainly helps if you have a crystal ball and know whether you are likely to have a lot or very few medical expenses in the coming year. A less expensive plan may be best for a healthy individual, while a more expensive plan might better protect a person who is likely to need more medical care. That is the traditional advice.

I discovered, however, while doing some extra number crunching to help a friend pick a plan from the New York marketplace-exchange (“Obamacare”) that the cheapest plan at least in his particular instance could be the best option by far even for someone likely to need a lot of medical care. This turns conventional wisdom on its head for some people.


First, here are some simple definitions to get out of the way:

Deductible: an amount of money you have to pay for medical services first before your insurance kicks in.

Copay: a fixed amount you pay out-of-pocket for a doctor’s visit or service.

Co-insurance: is similar to a copay, but it is typically a percentage of the total cost of a medical service that you have to pay out-of-pocket.

Out-of-pocket maximum: the maximum amount of money during the year that you have to lay out for covered services, not including premiums. Once the total of your deductible, co-insurance payments, and copays reaches the policy’s stated out-of-pocket maximum, the insurer pays for your covered benefits in full for the rest of the year.


In the past, MrConsumer has recommended the high-end “platinum” plan to his friend because it had no deductible and the out-of-pocket maximum was only $2,000. This means he only paid modest copays for covered services starting on day one, had no co-insurance, and once he met the $2,000 out-of-pocket maximum, he would not have to lay out a penny more for covered services for the rest of the year. He paid royally for this coverage: over $1,200 a month in 2018. But by summer, he reached his out-of-pocket maximum making all further services free.

In a million years, I would never have considered a low-end “bronze” plan with a $5,500 deductible, a $6,550 out-of-pocket maximum, and co-insurance on most services of 50% (meaning he would have to pay half the cost of medical procedures). The worry was that if he had a bad health year, this plan could have been so inadequate that it could have cost him a fortune. Or so I thought.

The New Calculations:

For 2019, however, MrConsumer pushed some new numbers, comparing the actual total costs of the four plans offered taking into account not just the premiums, but the out-of-pocket maximum as well. And a big surprise became evident.


Empire Blue comparison

This example compares Empire Blue’s four “metal” policy choices in New York for 2019 for an individual. These plans all cover the exact same medical conditions, services, and drugs, and use the same network of providers. The only differences are the amounts of the deductible, copays, co-insurance, and out-of-pocket maximums.

Compare the total annual premium of the bronze plan ($8,043) to the platinum plan ($16,520). Assuming my friend had no need for any medical services during the entire year of 2019 — the best (but unlikely) case scenario — he would save $8,000 by choosing the bronze plan. And now take the worst case scenario (the far right column in the chart above), where he had so many medical expenses that he hit the out-of-pocket maximum in both plans early in the year. In that case, the bronze plan would have cost him “only” $14,593 versus $18,520 for the platinum one — still an amazing savings of $4,000. (Note: there is a scenario where the minimum savings could drop to between $2000 and $4,000, but your head will explode if I try to explain it.)

If my friend needed a family plan, the total savings by choosing the bronze 2019 Empire Blue plan over the platinum one could be even more dramatic — between $15,000 and $24,000.

Where one might have expected the total cost figures in the right column above to be roughly equal (given the games the insurer’s accountants play of charging less in one area, but making it up in another), this was a big surprise to see the variation and potential savings.

The out-of-pocket maximum is a magical number that when combined with the annual premium can give you a truer picture of the real maximum costs of the plan, and help you spot a plan that is a mathematical anomaly in an insurer’s offerings. Such is the case here.

Warnings and Limitations:

A few words of caution. Besides the assumptions and facts mentioned above which might not hold true for other plans at other companies or in other states, if you choose a cheap plan and have an urgent and expensive medical need, you may have to come up with a large deductible and co-insurance right away.

Remember, this new calculation is most beneficial for people who expect to have substantial medical needs in the coming year. It is a treasure hunt of sorts to find the rare cases where the insurers’ accountants goofed up the mathematical structure of their plans making one plan’s total costs significantly lower than the others.

Before selecting a new plan, do a lot of comparisons, find plans with a large network, check to see that all your providers and drugs are included, make sure all the plans compared have identical benefits, crunch the numbers looking for a mathematical anomaly, ask a lot of questions to be sure your understanding of the plans is sound, read the actual policies carefully, and cross your fingers.

  1. Great analysis, Edgar.

    One easy addition to consider to your spreadsheet is that [I believe; IANAL] most employed people are able to pay their premiums with pre-federal-tax dollars, in which case the total premiums paid for those plans are effectively less than shown.

    For instance, if your friend is in the 24% federal tax bracket and has a lot of medical expenses, then the $4,000 tax savings of choosing the Bronze Plan instead of the Platinum Plan is really closer to $2,000, since the premium differential has to be reduced by 24%. I came up with this by multiplying the monthly premium difference of $706 ($1,376 – $670), and multiplying by .24, then by 12, yielding a $2,033 tax savings.

    This doesn’t consider the New York State taxes (which I don’t know anything about), or the Schedule A medical expense deduction, if it happened to kick in.

    Even considering taxes, though, the Bronze plan would seem to save your friend quite a bit of money, particularly if he doesn’t have a lot of medical needs in the coming year.

  2. A number of years ago, before my wife was Medicare-eligible, we needed to choose between two extended-COBRA plans. One was a high deductible plan and the other a standard plan at a very modest increase in the monthly premium. No brainer, I thought, but I ran the numbers in a spreadsheet anyway.

    To my complete surprise, the high deductible plan was the far better deal for all our scenarios except for a small window where they were about equal. And that did not even include the potential tax savings associated with high deductible plan.

    Lesson learned: health insurance plans are sufficiently complex that intuitive assumptions may well be wrong. Corollary: You are making assumptions about the future. Don’t sweat the small differences. They are the noise in the system that you just have to live with.

  3. I’ve been lucky that I haven’t needed to purchase health insurance outside of employer offerings, but I am glad that I see here that the math can work in the customers favor even for plans with less coverage upfront

  4. one more thing.. vote to elect people supporting a single payer, or at least or a more sensible insurance system!

  5. High deductible plans will also let you put money into a health savings accounts pre-tax. Sometimes your employer will even seed it yearly for you.

  6. While anyone is capable of a ‘goof,’ I believe that actuaries take into consideration the probability of different outcomes.

  7. Don’t forget to take into acct the HSA where the money you put into,the HSA IS DEDUCTIBLE FROM YOUR INCOME .
    YOU CAN PUT IN OVER AGE 55 $4550 a year and after 65 use the $$ anything you want.
