Formula Used
- Annual Premium: AnnualizedPremium = PremiumAmount × FrequencyFactor.
- Adjusted Charges: AdjustedCharges = ExpectedSpend × NetworkFactor.
- Covered vs Non-covered: CoveredCharges = AdjustedCharges × CoveragePercent.
- Deductible Payment: DeductiblePaid = min(Deductible, CoveredCharges).
- Coinsurance: CoinsPaid = (CoveredCharges − DeductiblePaid) × Coinsurance%.
- Copays: CopaysPaid = Copay × Visits.
- OOP Cap (covered services): MemberShareCovered = min(DeductiblePaid + CoinsPaid + CopaysPaid, OOPMax).
- Member Medical Total: MemberMedicalTotal = MemberShareCovered + NonCoveredCharges.
- Insurer Payment: InsurerPaid = max(0, CoveredCharges − MemberShareCovered).
- Estimated Tax Savings: TaxSavings = min(HSA/FSA, MemberMedicalTotal) × TaxRate%.
- Total Annual Cost: MemberTotal = (Premium − EmployerContribution) + MemberMedicalTotal − TaxSavings.

What this estimate captures
This tool converts your premium and cost-sharing rules into one annual view. With $10,000 expected allowed charges, a $1,500 deductible, 20% coinsurance, $30 copay, and eight visits, estimated member medical cost is $3,440. The plan’s payment on covered services is $6,560, so insurer share of covered charges is 65.6%. These ratios help you judge how strongly the plan protects you at your expected spending level for your household.
Premiums and contributions
Premiums are annualized from your selected frequency. A $250 monthly premium becomes $3,000 yearly. If an employer pays $1,200 annually, your net premium drops to $1,800, reducing total annual cost by the same $1,200. Use this field to compare workplace options fairly, especially when one plan looks “cheaper” only because the employer funds more of the premium.
Deductible and coinsurance behavior
Deductible spending is applied first, then coinsurance is calculated on the remaining covered charges. In the $10,000 scenario, $8,500 remains after the deductible and 20% coinsurance produces $1,700. Adding $240 of copays yields $3,440. When spend rises, coinsurance grows linearly until the out-of-pocket maximum is reached, so the slope of your costs depends heavily on the coinsurance rate.
Out-of-pocket maximum awareness
The out-of-pocket maximum typically caps deductible, copays, and coinsurance, but excludes premiums and non-covered items. With a $6,000 cap, the $3,440 member share stays uncapped. If out-of-network pricing increases costs, a 1.50× network factor turns $10,000 into $15,000; member covered share becomes $4,440 and insurer payment becomes $10,560. The optional “include non-covered in cap” switch shows a conservative what‑if when rules are uncertain.
Decision signals from scenarios
Compare plans at multiple spend points: low (routine care), medium (planned procedures), and high (unexpected events). If two plans differ by $1,500 in premium but one saves $2,000 at higher spend, the lower premium may not be the best value. Watch three outputs: total annual cost, insurer share of covered charges, and whether you approach the out-of-pocket maximum. Together they highlight both affordability and risk protection.
FAQs
1) What should I enter for “expected annual medical spend”?
Use your best estimate of allowed charges for the year. Start with last year’s total, then adjust for planned procedures, new medications, and expected visit frequency.
2) Does the out-of-pocket maximum include premiums?
Usually no. Most plans cap deductible, coinsurance, and copays, but premiums are paid in addition. This calculator follows that common structure unless you toggle the optional what‑if setting.
3) How do copays and coinsurance work together here?
Copays are added as a flat annual amount (copay × visits). Coinsurance is applied to covered charges after deductible is met. Both may contribute toward the out-of-pocket maximum, depending on plan rules.
4) What does the network cost factor represent?
It scales your expected spend for higher-priced care patterns. For example, 1.50× approximates heavier out-of-network use or higher negotiated rates when your plan reimburses less favorably.
5) How is HSA/FSA tax savings estimated?
Tax savings are approximated as min(HSA/FSA amount, your medical total) × tax rate. It’s a planning estimate; actual savings depend on eligibility rules and how funds are contributed and used.
6) Can I compare two plans with this page?
Yes. Run the calculator for Plan A, download CSV/PDF, then change inputs for Plan B and download again. Compare total annual cost and insurer share to see value versus protection.
