How to use this calculator

  1. Enter age and who will be covered under the plan.
  2. Set a local cost index to match your market.
  3. Choose plan level, network type, and key protections.
  4. Add discounts, employer contributions, and any tax credits.
  5. Press calculate to see monthly and annual estimates.
Tip: Start with default values, then change one factor at a time.

Formula used

This tool estimates a monthly premium using a multiplicative rating model, then subtracts credits. The model is designed for planning and comparison across scenarios.

Core equation
GrossMonthly = BaseAdultRate(age) × MemberUnits(adults, children) × LocalIndex × PlanFactor × NetworkFactor × TobaccoFactor × DeductibleFactor × OOPFactor × BenefitFactor
AfterAdmin = GrossMonthly × (1 + AdminLoad%)
AfterDiscount = AfterAdmin × (1 − WellnessDiscount%)
NetMonthly = max(0, AfterDiscount − EmployerContribution − TaxCredit)

What the estimate represents

This calculator models a premium using a baseline age rate and pricing multipliers. It is built for budgeting and comparisons, not underwriting. The output shows gross premium, administrative load, discount, and then credits, so you can see the steps clearly.

Inputs that drive premiums

Age sets the starting adult rate by band. For example, ages 36–40 use a 410 monthly baseline, while ages 41–45 use 470. Family cost is translated into “member units”: each adult counts as 1.00, and up to three children count as 0.60 each. Two adults and two children equals 2.20 units. A local cost index scales results; 0.85 mimics lower cost areas, 1.00 is average, and 1.25 reflects higher cost markets.

Benefit design tradeoffs

Plan level shifts premiums using factors: Catastrophic 0.75, Bronze 0.85, Silver 1.00, Gold 1.15, Platinum 1.30. Network choice adds another factor, such as HMO 0.95, EPO 1.00, POS 1.03, and PPO 1.08. Lower copays and lower coinsurance increase the benefit factor because the plan pays more. A 20% coinsurance and 30 copay behave like the baseline.

Protection limits and risk surcharges

Deductible and out of pocket maximum adjust the estimate around baselines of 2,000 and 8,500. Increasing the deductible trends the deductible factor downward, while lowering the out of pocket maximum trends the OOP factor upward. Tobacco use applies a 1.20 surcharge factor. Administrative load is applied as a percentage multiplier, such as 8% turning 1,000 into 1,080. A wellness discount is then applied, such as 5% reducing 1,080 to 1,026.

Scenario planning workflow

Run a baseline scenario first, then vary one input at a time to isolate impact. Compare monthly premium and annual cost, and use the deductible sensitivity chart to visualize how premiums move. Finally, enter employer contributions and tax credits to estimate your payment, and export CSV or PDF for review.

FAQs

What is the local cost index?

It scales the estimate for your market. Use 1.00 for average pricing, 0.85 for lower cost areas, and 1.25 for higher cost areas. It affects the premium before discounts and credits.

How are children priced in this model?

Children are converted into member units. Each adult counts as 1.00 unit, and up to three children count as 0.60 each. Additional children are not charged in the unit calculation.

Why does a lower deductible often raise premiums?

Lower deductibles shift more early costs to the plan. The deductible factor increases when the deductible is lower than the baseline, which raises the estimated premium. Higher deductibles reduce that factor within set limits.

How do copays and coinsurance change the estimate?

Lower copays and lower coinsurance imply richer benefits. The benefit factor increases when those values drop below the baseline. Higher copays or coinsurance slightly reduce the benefit factor in this planning model.

How are employer contributions and tax credits applied?

They are subtracted from the post-discount premium as monthly amounts. The calculator prevents negative results, so net premium cannot go below zero. Enter zeros if you are unsure about credits.

Is this a real insurance quote?

No. It is an illustrative estimate to compare scenarios and plan a budget. Actual prices depend on insurer filings, plan rules, underwriting limits where allowed, and enrollment timing.
