What This Calculator Does
This premium vs. deductible trade-off calculator helps individuals and families compare up to three health insurance plan options to find the most cost-effective choice for their expected medical spending. It calculates total annual costs (premiums plus out-of-pocket expenses) at low, expected, and high medical spending scenarios and identifies which plan wins at each level. The tool helps you see the true financial trade-off between paying more in monthly premiums for lower deductibles versus paying less upfront but bearing more risk.
The Formula
Each plan's total cost combines fixed annual premiums with variable out-of-pocket costs. Out-of-pocket costs are calculated in layers: first you pay the full deductible, then coinsurance applies to remaining costs, and the OOP maximum caps your total exposure. Plans with higher premiums typically have lower deductibles and OOP maximums, protecting you from high medical bills but costing more in low-use years.
Step-by-Step Example
Enter Plan A details
Low premium plan: $200/month, $3,000 deductible, $8,500 OOP max, 20% coinsurance.
Enter Plan B details
Mid premium plan: $350/month, $1,500 deductible, $6,000 OOP max, 20% coinsurance.
Enter Plan C details
High premium plan: $500/month, $500 deductible, $4,000 OOP max, 10% coinsurance.
Compare results
At $5,000 expected spend: Plan A = $5,800, Plan B = $5,900, Plan C = $6,450. Plan A wins at this spending level. At $25,000: Plan C wins with the lowest worst-case cost.

Common Mistakes to Avoid
Choosing the lowest premium plan without considering worst-case costs. A $200/month plan with an $8,500 OOP max could cost you $10,900 in a bad year, while a $500/month plan with a $4,000 OOP max caps at $10,000.
Not using your actual medical spending history. Look at your past 2 to 3 years of claims data to estimate expected spending rather than guessing.
Ignoring copay structures. Some plans have fixed copays for primary care and prescriptions that are not subject to the deductible, which can change the cost comparison.
Comparing plans without considering network differences. A cheaper plan with a narrow network may limit your provider access.
Forgetting prescription drug costs. High-cost medications can push your out-of-pocket spending to the maximum regardless of which plan you choose.
