Frequently Asked Questions
1. What does this planner estimate?
It estimates employer-side annual benefits spending across medical, dental, vision, life, wellness, retirement, administration, trend increases, and contingency reserve planning.
2. Should I enter employee-only or blended premiums?
Enter a blended average that reflects your expected enrollment mix. That keeps the budget more realistic when employees choose different coverage tiers.
3. What is the employer share percentage?
It is the portion of each premium paid by the employer. The calculator multiplies the premium by this share before annualizing the cost.
4. Why include participation percentages?
Not every employee enrolls in every benefit. Participation rates convert headcount into expected enrolled employees for more accurate forecasting.
5. What should I include in administration cost?
Include broker fees, software, enrollment support, internal operations, and other recurring benefits administration costs charged per employee each month.
6. What does the annual trend percentage represent?
It represents expected year-over-year cost growth. Teams often use it to model premium inflation, utilization changes, or anticipated carrier increases.
7. Why add a reserve percentage?
A reserve gives extra budget room for surprises, enrollment shifts, pricing changes, and midyear adjustments that were not captured in the base inputs.
8. Can I use this for multi-location planning?
Yes. Run separate scenarios by office, region, or population segment, then compare exported tables to create a consolidated annual budget view.
