Formula Used
Employee Base Total = Enrolled Employees × Base Employee Premium
Age Adjusted Total = Employee Base Total × Average Age Factor
Tobacco Surcharge = Age Adjusted Total × Tobacco User Rate × Tobacco Load
Dependent Premium = (Covered Spouses × Spouse Premium) + (Covered Children × Child Premium)
Risk Load = (Age Adjusted Total + Tobacco Surcharge + Dependent Premium) × Risk Load Percentage
Gross Premium = Age Adjusted Total + Tobacco Surcharge + Dependent Premium + Risk Load
Net Before Tax = Gross Premium − Wellness Discount + Admin Fee
Final Monthly Premium = Net Before Tax + Taxes
Employer Share = Minimum of Final Premium and (Contribution % Share + Flat Subsidy)
Employee Share = Final Monthly Premium − Employer Share

FAQs
1. What does this calculator estimate?
It estimates a monthly group premium for employee benefits. The result combines employee premium, dependent costs, surcharges, loading, discounts, taxes, and employer funding rules.
2. What is the average age factor?
The age factor adjusts the employee base premium for the group’s age profile. A value above 1.00 increases cost, while a value below 1.00 reduces it.
3. How is the tobacco surcharge applied?
The calculator applies the tobacco load only to the age-adjusted employee premium and only to the portion of employees marked as tobacco users.
4. Are spouse and child premiums optional?
Yes. Enter zero for any dependent category that does not apply. The calculator will exclude that premium component automatically.
5. Why add both employer percentage and flat funding?
Some employers fund premiums with a percentage share plus a fixed monthly subsidy per employee. This tool supports both methods in one estimate.
6. Does the calculator cap employer funding?
Yes. Employer funding can never exceed the final monthly premium. Any excess is capped automatically, and employee share cannot fall below zero.
7. What does the chart display?
The chart shows how each pricing component affects the final monthly premium. It highlights increases from surcharges and fees, plus the reduction from wellness discounts.
8. Can I use this for budgeting?
Yes. It works well for forecasting monthly and annual benefit costs, comparing funding strategies, and reviewing employer versus employee cost responsibility.
