I'm sorry nobody replied, I must have missed your thread here.   To answer it I don't believe if your speaking about the actual cost of purchasing the unit..  I've put together a post in tutorials here   https://plarium.com/forum/en/soldiers-inc-mobile-warfare/game-tutorials/45946_unit-cost-2/

If your talking about the consumption rate of each unit, this would be based on your specific tech and units.  As tech changes the consumption of each unit as you upgrade it, ie. Rations Consumption (Mech inf.).

Hope this answers your question.
