How volume-rated coverage is supposed to work
Basic Life isn't priced per person — it's priced per unit of coverage volume. A typical plan design: coverage equals 1× annual salary, rounded up to the next $1,000, capped at a guarantee-issue maximum (say, $150,000), at a rate of $0.18 per $1,000 of volume per month.
Four separate steps, each with its own way to go wrong:
| Step | Rule | Example: salary $162,400 | Example: salary $99,010 |
|---|---|---|---|
| 1. Base volume | 1× salary | $162,400 | $99,010 |
| 2. Round | up to next $1,000 | $163,000 | $100,000 |
| 3. Cap | GI max $150,000 | $150,000 | $100,000 |
| 4. Premium | volume ÷ 1,000 × $0.18 | $27.00 | $18.00 |
The 10× error
Life rates get quoted two ways in this industry: per $1,000 of coverage (typical for Basic Life) and per $100 (typical for some voluntary and disability products). Same rate card, same decimal, different divisor. When a plan is set up in the carrier's billing system with the wrong basis, every premium on that plan is off by exactly a factor of ten:
| Member | Volume | Correct (per $1,000) | Billed (as per $100) | Overcharge |
|---|---|---|---|---|
| Salary $162,400 (capped) | $150,000 | $27.00 | $270.00 | $243.00 |
| Salary $99,010 | $100,000 | $18.00 | $180.00 | $162.00 |
Here's why it survives review: $270 is not an alarming number. It sits on the bill two lines below an $864.61 family medical premium and nobody blinks. Percentage-wise it's a 900% overcharge — the single largest relative error a bill is likely to contain — camouflaged by being absolutely small. Totals review can't catch it; only recomputing volume × rate, line by line, can.
The quieter volume errors
- Stale salary. Volume follows salary, and salary changes don't flow to carriers as reliably as enrollment changes do. A raise in March that never reached the carrier means under-insured coverage (a claims problem, not just a billing one) or an under-billed premium that back-bills later.
- Rounding direction. Round up to the next $1,000 vs. round to the nearest: a $99,010 salary is $100,000 one way and $99,000 the other. Eighteen cents a month, times every employee near a rounding boundary, forever — and a mismatch means every reconciliation you attempt has phantom pennies that erode trust in real findings.
- Age bands. Age-rated voluntary life re-prices at band crossings (35, 40, 45…), but when? Birthday month, policy anniversary, or January 1? The contract picks one; systems frequently apply another. Every band crossing is a small, permanent rate error until reconciled.
- The GI cap applied late or never. An executive's $300,000 salary billed at full volume instead of the $150,000 guarantee-issue cap doubles the premium — and if a claim ever pays at the capped amount, you funded coverage that never existed.
