Work out human life value instantly with clear inputs, formula shown and shareable results.
Human life value is the present value of the income an earner would have contributed to their dependants over their remaining working life, after deducting what they would have spent on themselves. It is the actuarial basis for both life cover sizing and fatal-accident compensation.
Annual contribution
Contribution = Annual income x (1 - Personal consumption %)
Human life value
HLV = Contribution x [1 - (1 + r)^-n] / r
Indicative estimate only. Fees, entitlements, limits and formulas vary by jurisdiction, statute, policy wording and the facts of the case. This is not legal, tax, insurance or financial advice — confirm with a qualified professional or the relevant authority.
Use a rate net of expected income growth. If income grows roughly with the discount rate, the real rate is close to zero and the undiscounted total is a reasonable proxy.
Courts commonly deduct one-third for a married earner with dependants, and up to one-half for a single earner.
