Understanding health plan cost comparison — two-scenario comparison
Everyday editorial team · GEOINNOVATION CO., LTD · Published · Updated
What this calculation is for
Comparing health plans requires both premiums and the cost-sharing rules that apply when care is used. The plan with the lowest deductible or lowest premium need not be cheapest at every level of spending.
How the method works
The model adds annual premium, modeled spending below the deductible and the entered member coinsurance after the deductible. Both plans are tested against the same care-spending assumption. The displayed model uses: Annual premium plus the estimated member share after deductible for entered covered care.
A worked example
For an illustrative health plan cost comparison scenario, use Plan A monthly premium: 400 $; Plan B monthly premium: 320 $; Plan A deductible: 1500 $; Plan B deductible: 3000 $; Expected annual covered care before insurance: 5000 $; Plan A coinsurance after deductible: 20 %; Plan B coinsurance after deductible: 20 %. The modeled lower estimated annual plan cost is $7,000. These are example assumptions, not current prices, official benefit amounts or personalized advice.
Assumptions and real-world differences
The simplified calculation excludes out-of-pocket caps, service-specific copays, uncovered care and network pricing. It is not a recommendation to switch coverage. A simplified comparison; network, prescriptions, copays, out-of-pocket maximum and coverage rules vary.
Building two independent scenarios
Scenario A and Scenario B each have a complete set of inputs for this health plan cost comparison calculation. Change several inputs in B when comparing genuinely different plans, then inspect the B-minus-A headline difference and the detailed rows. When multiple inputs change, the total difference cannot be attributed to just one of them.

- Scenario A — Plan A monthly premium
- 400 $
- Scenario A — Plan B monthly premium
- 320 $
- Scenario A — Plan A deductible
- 1,500 $
- Scenario A — Plan B deductible
- 3,000 $
- Scenario A — Expected annual covered care before insurance
- 5,000 $
- Scenario A — Plan A coinsurance after deductible
- 20 %
- Scenario A — Plan B coinsurance after deductible
- 20 %
- Scenario B — Plan A monthly premium
- 500 $
- Scenario B — Plan B monthly premium
- 320 $
- Scenario B — Plan A deductible
- 1,500 $
- Scenario B — Plan B deductible
- 3,000 $
- Scenario B — Expected annual covered care before insurance
- 5,000 $
- Scenario B — Plan A coinsurance after deductible
- 20 %
- Scenario B — Plan B coinsurance after deductible
- 20 %
Scenario B result: $7,240
Scenario A: $7,000. Lower estimated annual plan cost.
- Scenario A main result: $7,000
- Scenario B main result: $7,240
- Numeric difference (B − A), in result units: 240
Frequently asked questions
- Is the coinsurance field the insurer’s share?
- Use the member-paid percentage requested by the field. Entering the insurer’s percentage would reverse the intended cost share.
- Which inputs should I check before using this health plan cost comparison estimate?
- Check plan a monthly premium, plan b monthly premium, plan a deductible, plan b deductible, expected annual covered care before insurance, plan a coinsurance after deductible, plan b coinsurance after deductible. Match each field’s unit and time period, then compare the detailed rows rather than treating the headline alone as the complete answer.
- Why is this different from the one-factor comparison?
- The one-factor tool changes only plan a monthly premium. This version lets all model inputs differ, so it is more flexible but does not isolate the effect of any single change.
