Business case
What is the old application actually costing you to keep alive?
Most legacy applications are budgeted as a single licence line, which is why retiring them looks less valuable than it is. Enter what each component actually costs and the model returns an indicative annual saving, three-year saving and payback period.
All figures in pounds per year, except the one-off project estimate. Nothing is submitted — the calculation runs entirely in your browser.
Indicative modelling only. Actual savings depend on contracts, infrastructure, support model and implementation scope.
The calculator models one application from figures you already have. An assessment establishes the whole estate: what has to be retained, at what volume, under what retention rules, and what a scoped retirement would take.
