About This Calculator
Cloud migration decisions are often made on incomplete financial data. This calculator models the true total cost of ownership — including hardware amortization, staffing, data center overhead, migration costs, and cloud growth — across three deployment models over three years.
How to use it: Enter your current on-premises costs and your estimated cloud costs using the sliders below. The chart and summary update in real time. The multi-cloud estimate applies an 18% complexity premium over single-cloud costs, reflecting typical operational overhead.
