Costs and migration planning
Build a budget covering transition, training, operations and retained licenses. Use your own figures in the calculator and compare the result with the capabilities you need to preserve.
Compare total cost with your own figures
All annual amounts must cover the same scope. Enter 0 where there is no cost. The calculation stays in your browser until you choose to share it.
Changing currency clears amounts. No exchange-rate conversion is applied.
Current TCO = years × current annual cost. Future TCO = transition + years × future annual cost. Savings = current TCO − future TCO. Constant costs, excluding inflation, tax and financing. This is not a quote or a savings guarantee.
