Application Rationalization Calculator (TIME model)
Estimate how much of your application portfolio is redundant and what consolidation could save, using the TIME model — Tolerate, Invest, Migrate, Eliminate. Adjust the inputs and the estimate recalculates live.
Your portfolio
Enter rough numbers — this is a directional estimate, not an audit.
Total business applications in scope.
Licences, hosting, support and maintenance combined.
Share of applications you suspect are duplicated or overlapping.
Share of at-risk cost you assume is actually recoverable after migration effort.
Estimated outcome
All figures below are estimates derived from your inputs and the assumptions shown.

TIME distribution (estimate)
How your applications could split across the four TIME dispositions.
- Tolerate63 apps · 53%
Keep as-is for now; functional but not strategic.
- Invest27 apps · 23%
Strategic apps worth further investment.
- Migrate12 apps · 10%
Consolidate or move to a better-fit platform.
- Eliminate18 apps · 15%
Retire redundant or low-value apps.
How this is calculated
redundant apps = applications x redundancy% eliminate = redundant x 0.6 · migrate = redundant − eliminate kept = applications − redundant invest = kept x 30% · tolerate = kept − invest gross at risk = redundant x average annual cost estimated savings = gross at risk x recoverable factor
Assumptions baked in (editable above where shown)
- Of the overlapping apps, ~60% are assumed eliminable and ~40% consolidated/migrated.
- ~30% of retained apps are assumed strategic enough to invest in (Invest); the rest are Tolerated.
- Only the recoverable factor you set is treated as realised savings — migration always has cost and friction.
This is a directional estimate for planning conversations only. It uses no external benchmarks. Actual savings depend on contracts, dependencies, and execution.
Want a grounded number for your real portfolio?
We can run the TIME model against your actual application inventory and dependencies — no guesswork.
