Comprehensive operational expenditure analysis with 30+ countries, climate-adjusted calculations, and flexible staffing models
CAPEX gets the boardroom attention. OPEX is what actually kills the margin — year after year, silently.
Energy alone can eat 40–60% of your annual operating budget, and that's before you factor in staffing models, maintenance contracts, climate-driven cooling penalties, and the 30+ country-specific variables that turn a "simple" cost projection into a guessing game. This calculator maps all of it: pick your country, set your IT load, choose between in-house, hybrid, or outsourced staffing, and see how geography and climate reshape the numbers. It won't replace a full financial model — but it will show you where the real cost drivers hide, before they show up in your P&L.
