Estimate migration investment, cloud run costs and break-even versus on-prem operations.
In brief
The investment frame for a cloud migration is EUR 8,925 – 4,534,971 excl. VAT. Lift-and-shift or rebuild and the number of applications move the project inside that band.
The upfront cost can be spread over 72 months. Terms are on the software financing page.
Related: on-premise or cloud.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.

FAQ
It blends landing-zone work, workload moves, data transfer and operational hardening.
Larger estates or aggressive availability targets widen the range because more validation cycles and rollback rehearsals are required.
Model 24–36 months including people time, licences, support and residual on-prem costs.
That highlights break-even honestly instead of comparing only monthly IaaS invoices.
Need a migration narrative for leadership?
We translate technical milestones into budget blocks and risk notes.
Because it includes redesign, deeper testing and often data model work.
The upside is lower long-term toil once the workload matches cloud-native patterns.
Weak observability, unclear data classification and teams still operating the old way.
Budget explicit runway for monitoring, guardrails and training so incidents do not erase savings.
Stateless applications are often easy to move, while database-bound or tightly coupled systems require more effort.
We assess per workload whether a simple move, an adaptation or a rebuild makes sense. This classification largely determines the values in this cost calculator.
The actual switchover carries the greatest operational risk, so we carefully plan cutover windows, fallback scenarios and data synchronisation.
A well-prepared cutover minimises downtime. The effort for this planning is well invested because it avoids expensive production disruptions.
Whether classic servers in the cloud, containers or serverless services are most economical depends on load, fluctuations and maintenance effort.
Serverless approaches often save during idle but require adjustments. In the calculator you can compare different operating models as scenarios.
Without cost control, cloud bills quickly rise through oversized resources or unused services.
We set up monitoring, scaling rules and budget alerts. These measures involve one-off effort but lower the monthly operating costs permanently and predictably.
Single-cloud is simpler to operate and usually cheaper but creates dependence on one provider.
Multi-cloud increases flexibility and resilience at the price of higher complexity. We recommend aligning the strategy with real requirements rather than theoretical maximum goals.
The duration ranges from a few weeks for individual applications to several months for complex landscapes with many dependencies.
An upfront analysis phase brings clarity about realistic timeframes. In the cost calculator you should set analysis, move and stabilisation as separate phases.
Workload assessment, migration strategy, and FinOps—so you don't pay twice (old + new).
1. Workload assessment
We map applications, data, and dependencies and estimate migration effort and ongoing cloud cost per workload.
2. Migration strategy per workload
Lift-and-shift, replatform, or refactor—each has different cost and timeline. We name what makes economic sense per workload.
3. Parallel operation and cutover plan
We calculate how long old and new must run in parallel (often underestimated) and which cutover risks may generate additional cost.
4. FinOps and rightsizing
We plan tagging, budgets, and rightsizing from day one so cloud cost doesn't explode after 6 months.
| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |

Non-binding overall range from the cloud migration calculator: EUR 8,925 – 4,534,971 excl. VAT.
Methodology: The estimates are based on historical project data, complexity drivers and standard implementation assumptions. Results are a non-binding indication only; effort and price must be calculated individually.
