AWS migration business-case calculator
Compare staying with moving to AWS, including migration costs, overlapping bills, confirmed credits and the operating cost after credits expire.
Does the migration still make financial sense without temporary incentives?
How this calculator works
Use one currency and a defined workload boundary. Enter actual source costs and a separately estimated target design. This tool does not fetch AWS prices or inspect your invoices.
The move scenario includes implementation at month zero, both source and target costs during overlap, an exit charge at cutover, and residual source costs afterward.
Confirmed credits offset only the entered eligible target usage during the entered validity window. The comparison without credits remains visible. Unconfirmed credits are not applied.
Cumulative savings equal cumulative stay costs less cumulative move costs. Break-even is the first post-cutover month with non-negative savings that remain non-negative through the selected horizon. It is not a guarantee beyond that horizon.
Change assumptions and compare downside cases. A positive cash comparison does not establish technical suitability, customer benefit, security or operational readiness.
What to prepare
Source invoices, a target architecture estimate, support and licensing costs, migration effort, dual-running duration, exit obligations, residual costs and any confirmed credit terms.
