Work out opportunity cost of a purchase instantly with clear inputs, formula shown and shareable results.
Every purchase has an opportunity cost: what the same money would have grown into if invested instead. Showing it in today's purchasing power as well as nominal terms keeps the comparison honest.
Opportunity cost
Nominal = amount × (1+r)^years; real = amount × [(1+r)/(1+inflation)]^years
