The methodology, in fullFive actuarial moves, one defensible number per line.
Five core adjustments inside a nine-step sequence. The same logic is footnoted on the report, so the answer to an underwriter’s pushback is already on the page.
Every step, EHC / Dental
- 01
Strip large claimants from the claims
Claims above the carrier’s stated pooling threshold come out, leaving the experience the group is responsible for.
- 02
Remove the pooling charge from gross premium
What’s left is net premium — the money actually available to pay the group’s claims.
- 03
Complete the claims with IBNR
Incurred-but-not-reported claims are added. The figure comes from the carrier, your library or you — never guessed.
- 04
Compute the real net loss ratio
Incurred claims ÷ net premium. Usually higher than the carrier’s quoted ratio, and it’s the negotiating number.
- 05
Trend to the renewal midpoint
Experience is projected to the period being priced, on the renewal’s own trend where it states one.
- 06
Credibility-blend against the manual rate
The square-root rule weights the group’s own experience against last year’s rate trended forward — never the ask being challenged.
- 07
Gross up by the carrier’s own target loss ratio
The carrier’s own pricing target, with the pooling charge put back so the comparison stays like-for-like.
- 08
Run the carrier’s own rate formula
Where the renewal prints its loss ratios, target, trend and credibility, blankit runs their formula and never counters above it.
- 09
Cap at the carrier proposal
The fair premium never exceeds the ask. Where the math supports the ask, the line reads as defensible rather than challenged.
The nine steps apply to EHC and Dental, the lines a carrier rates on the group’s own claims. Life, Dependent Life, AD&D, Critical Illness, disability and EAP aren’t experience-rated, so they aren’t argued on claims math. They still open just below the ask, and the report says which figures are rated and which are position.
Some lines are accepted exactly as proposed, because countering them would cost your client: a contractual rate cap the carrier honoured; a decrease on a line whose own claims argue for an increase; a pooled rate held flat on an ageing group; a fully pooled group; and a disability line the carrier’s own published method already supports. That last finding is yours alone — the carrier’s copy says only that the line is accepted. A breached cap is challenged, with the capped rate as the target.
Where the renewal includes age-band tables, blankit splits an age-rated line’s increase into what an older census explains and what is the carrier repricing — drawn from their own numbers.
