| Field | Example value | Notes |
|---|---|---|
| Employees | 50 | Headcount |
| Average FTE % | 100% | All full-time |
| Average salary | $60,000 | Annual per employee |
| Medical monthly | $450 | Employer share |
| Medical enrollment | 85% | Eligible participation |
| Retirement match | 4% | With 65% participation |
| PTO days | 15 | Backfill factor 30% |
| Admin % | 6% | Vendor + internal admin |
Employee benefits spending is typically concentrated in medical coverage, retirement match, and payroll-linked burdens. Using the sample scenario (50 employees, $60,000 average salary, 100% FTE), a moderate employer medical share of $450 per month with 85% enrollment quickly becomes a six‑figure annual line item, before dependent add-ons and administration.
This calculator treats enrollment rates as multipliers, so small participation shifts can materially change totals. If medical enrollment moves from 85% to 75%, the medical component drops by roughly 11.8%. Dependent coverage adds another layer: a $200 monthly add-on at 40% dependent coverage increases the effective medical monthly cost by $80 for enrolled employees.
Bonuses, employer payroll taxes, unemployment insurance, and workers compensation scale directly with payroll. When compensation grows, these costs rise automatically even if plan premiums stay flat. Setting payroll tax at 7.65% and adding 5% bonus can create meaningful budget pressure, especially in high-salary teams or rapid hiring cycles.
The tool reports cost per headcount and cost per FTE-weighted employee. Use per-headcount for high-level budgeting and per-FTE for roles with significant part-time mix. The benefits load percentage helps compare benefit richness across departments because it normalizes benefits against payroll rather than headcount alone.
Annual increase modeling provides a simple forecast for next-year benefits. Apply conservative increases when negotiating renewals, and use scenario runs to evaluate plan design changes: adjust enrollment, match caps, PTO backfill factor, or commuter eligibility. Export CSV for finance reviews and PDF for leadership updates, keeping assumptions transparent. Include administration at 6% to reflect vendor fees and HR time, and track training and wellness per employee to capture non-insurance costs fully. To prioritize initiatives, sort the exported breakdown and focus on the top three components. A 1% change in participation, premium, or match rate can be modeled instantly, helping HR and finance align on trade‑offs and timing before renewal decisions finalize.
FTE% converts headcount into an effective workforce size. This keeps costs realistic when many employees are part-time, seasonal, or shared across roles.
A dependent add-on is applied only to the portion of enrolled employees with dependent coverage. It increases the medical monthly amount before annualizing.
The cap limits employer matching to a maximum annual amount per participating employee. If the uncapped match exceeds the cap, the tool uses the lower capped value.
Use the share of PTO that requires incremental coverage, such as temporary labor or overtime. If PTO is absorbed without extra cost, set the factor to 0%.
These items scale with payroll and often behave differently from premiums. Separating them helps you see the impact of raises, hiring, and bonus changes.
It projects next-year benefits cost from the current estimate. Use it for budgeting sensitivity and renewal planning; run multiple scenarios to compare outcomes.
