Work out dependant cost estimate instantly with clear inputs, formula shown and shareable results.
The cost of supporting dependants over many years is dominated by inflation, not by the first year's figure. Comparing the nominal total against today's prices shows how much of the burden is purely price escalation.
Dependant cost
Total = Σ dependants × annual cost × (1 + inflation)^year
