The Coverage Overlap Most Employers Never Quantify

Ask a CFO their renewal trend, their per-employee cost, or their stop-loss attachment point and you'll get an answer from memory. Ask what share of the workforce carries qualifying coverage overlap — coverage the plan pays as though it doesn't exist — and you'll get silence. Almost no employer has ever measured it.

In a typical large workforce, that share runs near 30%. Yours may be higher or lower; composition drives it — clinical staff, hourly manufacturing teams, hospitality and casino workforces, and public payrolls all tend to run high. Whatever the share is, your plan is priced as if it were zero.

Nobody in the standard arrangement is paid to look. Your carrier earns on premium volume — quantifying avoidable spend is against its interest. Your broker earns on the renewal — the analysis sits outside that cycle. And internally, the data lives in a census file HR uses for enrollment, not analysis.

So one of the larger findable numbers in your P&L stays unfound — not hidden, just never anyone's job.

A confidential model, built from a de-identified census, quantifies three things: how much overlap your workforce actually holds, what participation is realistic if employees were offered a voluntary option that leaves them better off, and what that's worth annually — with every assumption stated. Where the fit exists, historical results have run in the thousands of dollars per participating employee.

The overlap is either in your census or it isn't. Twenty minutes establishes whether it's worth modeling.
