Model servers, storage, transfer, labor, and licensing precisely. Compare baseline hosting against target run-state costs. Estimate migration costs, savings, risks, and payback with confidence.
| Scenario | Servers | Storage TB | Transfer TB | On-Prem Monthly | Cloud Monthly | Migration Cost | 24-Month Savings |

| Branch Systems | 12 | 8 | 5 | $8,250.00 | $6,940.00 | $9,800.00 | $21,640.00 |
| ERP Estate | 24 | 18 | 12 | $15,190.00 | $12,318.00 | $15,624.00 | $53,304.00 |
| Analytics Cluster | 36 | 40 | 18 | $26,600.00 | $24,780.00 | $24,500.00 | $19,180.00 |
Use the table as a benchmarking guide when estimating mixed workload migration waves.
Lift and shift moves workloads with minimal redesign. Servers, operating systems, and applications remain mostly unchanged while infrastructure moves to hosted resources. It is usually faster than deeper modernization, but it may not deliver every architecture efficiency gain.
A performance buffer covers burst demand, monitoring overhead, and sizing uncertainty. It reduces the chance of under-provisioning during early migration waves, especially when legacy servers were capacity constrained or poorly documented.
Yes. Planning, tooling, testing, training, downtime, and contingency are added to the hosted total cost of ownership. That makes payback and ROI more realistic than comparing monthly costs alone.
Managed services uplift represents extra recurring spend for monitoring, patching, backup operations, platform engineering, or support purchased from a provider or migration partner.
If hosted monthly run costs exceed the current baseline, the project may never recover its one-time spend within the selected horizon. The calculator shows this directly instead of forcing a misleading payback month.
Only partially. This model is best for near like-for-like moves. Larger architecture changes usually need different assumptions for databases, scaling behavior, licensing, and engineering effort.
Twelve months shows near-term budget effects. Twenty-four to thirty-six months usually captures commitment discounts, operational shifts, and migration recovery timing more clearly.
Savings compare total ownership costs across the horizon. ROI measures return against the one-time migration investment, so similar savings can still produce different capital efficiency outcomes.
