How to use this calculator

  1. Enter your monthly premium and any employer premium contribution.
  2. Fill in deductible, coinsurance percentage, and out-of-pocket maximum.
  3. Choose a modeling method: Basic for copays, Detailed for allowed costs.
  4. Add your expected yearly usage: visits and prescription fills.
  5. Enter other eligible charges for labs, imaging, and procedures.
  6. Submit to see totals, then export CSV or PDF.
For plan comparisons, save two exports and compare totals side-by-side.

Premium Structure and Employer Support

Annual premium is the most predictable cost. Multiply the monthly premium by twelve, then subtract any employer monthly contribution. The calculator shows gross premium, employer portion, and your net premium. If two plans have similar benefits, a $50 monthly premium difference equals $600 per year, before medical spending.

Deductible and Coinsurance Mechanics

After premium, the next driver is cost sharing. Eligible allowed charges first reduce the deductible, then the remaining balance is multiplied by the member coinsurance percentage. A $2,000 deductible with 20% coinsurance means the first $2,000 is paid in full, then $1,000 of additional allowed charges adds $200 of coinsurance.

Out-of-Pocket Maximum and Risk Control

The out-of-pocket maximum limits medical cost sharing but does not include premium. In Basic mode you can decide whether copays count toward the maximum, matching many plan designs. The report also shows cap savings, which estimates how much spending was prevented by the limit. If expected charges exceed the maximum, the plan becomes primarily premium driven.

Utilization Scenarios and Cost Drivers

Small changes in utilization can shift totals quickly. Frequent specialist visits and brand prescriptions raise copay totals, while imaging, labs, and procedures increase eligible charges that flow through deductible and coinsurance. Use the visit and prescription counts to model ranges for low, moderate, and high usage. Track which inputs move the out-of-pocket share above 40%, a common sign of higher financial volatility.

Using Results for Plan Selection

Compare total annual cost and effective annual cost. Effective cost subtracts employer HSA or HRA contributions, which can materially change the best choice in high-deductible options. When two plans are close, prioritize the lower out-of-pocket maximum for downside protection, or the lower premium for predictable budgeting. Export both scenarios to document your assumptions and revisit them quarterly. Use the waterfall plot to see how premium, expected spending, and employer funding combine. If your effective monthly cost exceeds your target, adjust utilization assumptions or test a second plan design today quickly.

FAQs

1) Does this calculator include dental or vision costs?
No. It focuses on medical plan premium and medical out-of-pocket spending. You can add dental or vision premiums into the monthly premium field, but benefits and cost sharing will not be modeled separately.
2) Why does the result change when copays count toward the out-of-pocket maximum?
Some plans include copays in the out-of-pocket cap, while others do not. If copays count, the cap can reduce total spending sooner. If they do not, copays stay added even after the cap is reached.
3) What is the difference between gross and net premium?
Gross premium is the full monthly premium multiplied by twelve. Net premium subtracts the employer monthly contribution, showing what you actually pay for coverage over the year.
4) What should I enter for allowed charges in Detailed mode?
Use the plan’s negotiated or allowed amounts, not the billed charges. If you only have billed charges, apply a conservative discount based on prior claims or insurer tools, then test a range for sensitivity.
5) How do employer HSA or HRA funds affect the estimate?
Employer HSA or HRA contributions do not change medical spending, but they reduce your effective cost because they offset what you must fund yourself. The calculator reports both total cost and effective cost.
6) Can I compare two plans fairly with this tool?
Yes, if you use the same utilization assumptions for both plans and update deductibles, coinsurance, copays, and caps to match each design. For network differences and drug tiers, adjust allowed costs or copays accordingly.
