Human Life Value: How Income Replacement Maths Works
Explains how human life value models convert future earnings, obligations, and discount rates into a present-value insurance benchmark.
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
- Future earnings are projected across the protection period
- Personal consumption is removed
- Debts and obligations can be added separately
- d = discount rate
Why HLV is a finance calculation
Human life value is fundamentally a present-value problem. The core question is what stream of economic value disappears if one income is removed.
That fits Plain Figures well because the concept is sensitive, but the arithmetic is still explicit and auditable.
Why simple income multiples fall short
Two households on the same salary can have very different protection gaps once debt, childcare, and timing are included. A flat multiple hides those differences.
A formula-first page is useful because it shows which assumptions are moving the result and why.
FAQ
Is human life value the same as a policy recommendation?
No. It is an economic benchmark, not a product recommendation.
Why subtract personal consumption?
Because not every pound of lost earnings needs to be replaced in the household budget.
