This extension page exists to support specific long-tail queries with formula-first explanations. It is intentionally narrow, deliberately opinion-free, and designed to lead into the relevant calculator rather than replace it.

Plain Figures does not recommend products, wrappers, or financial actions here. The goal is to make the arithmetic and the assumptions visible.

Core Formula

TCOR identity
TCOR = premiums + retained losses + risk control spend + administration
  • Premiums capture transferred risk cost
  • Retained losses capture self-funded claim cost
  • Administration includes internal and external friction
  • Risk control spend includes prevention cost

Why premium alone is weak

A lower premium does not automatically mean lower risk cost. Cost can simply move into retained losses or operational friction.

TCOR pages matter because they shift the question from insurance price to total risk cost.

Where the page becomes decision-useful

TCOR is strongest when comparing scenarios such as higher deductibles, different structures, or additional controls.

That makes it a high-intent professional page rather than generic insurance commentary.

FAQ

Does a lower premium always reduce TCOR?

No. If retained losses or admin friction rise more than premium falls, TCOR can increase.

Why include control spend?

Because prevention and mitigation are part of the real cost of managing risk.
