How CIOs evaluate the total cost of ownership in cloud migration
SEP. 5, 2025
5 Min Read
Most companies overshoot cloud migration budgets because they miss costs beyond provider pricing.
Migrating to the cloud is a financial and strategic initiative that requires careful planning from day one, not a narrow IT task. CIOs often face unforeseen expenses in areas like integrating cloud systems with legacy applications, retraining teams, or strengthening security and compliance. Hidden items like these can quickly erode anticipated savings and stall support from finance. Treating cloud migration as a pure IT expense is a mistake; it should be managed as a strategic business investment with rigorous cost oversight from the outset, and independent research shows nearly three in four organizations exceeded their set cloud budgets in the most recent fiscal year.
When CIOs adopt a comprehensive total cost of ownership perspective from day one, expectations stay realistic and budget surprises shrink. A complete view covers provider fees, refactoring needs, integration work, security and compliance, training, and the cost of planned downtime during cutover. This discipline creates a credible RFP, secures buy-in from finance and the board, and sets the baseline for tracking ROI over several years. The payoff is clearer priorities, faster time to value, and cloud investments that deliver measurable business outcomes.
key-takeaways
- 1. CIOs must evaluate all direct and indirect costs upfront, not just provider pricing, to prevent budget overruns.
- 2. Integration challenges, downtime, and technical debt often become hidden costs that can erode expected savings.
- 3. A multi-year view of cloud spending provides a clearer picture of ROI and helps sustain value.
- 4. Aligning cloud budgets with business outcomes ensures spend is justified as an investment rather than an IT cost.
- 5. A rigorous TCO framework creates stronger buy-in from finance and stakeholders while delivering measurable business value.
Every cloud migration requires a holistic cost evaluation from day one

A cloud migration’s success hinges on understanding all the costs involved from the very beginning. Too often, initial RFPs fixate on cloud vendor fees while ignoring other critical migration expenses. This narrow view can leave CIOs blindsided by costs for rearchitecting applications, integrating systems, or other necessities that weren’t in the original plan. To avoid these surprises, IT leaders must evaluate costs holistically from day one, considering every element of the migration.
- Migration project and tooling – Budget for the migration team, planning, testing, and any specialized tools or consultants needed for execution.
- Cloud infrastructure and licenses – Ongoing cloud service fees for compute, storage, and networking, plus any new software licenses or third-party services.
- Application refactoring – Costs to rewrite or optimize legacy applications so they run efficiently in the cloud, which can be substantial if a simple “lift-and-shift” isn’t possible.
- Integration and data migration – Expenses for connecting cloud systems with on-premises environments and safely migrating large volumes of data without disruption.
- Security and compliance – Investments in cloud security controls, monitoring, encryption, and compliance audits (for regulations like HIPAA or GDPR).
- Training and change management – The cost of upskilling IT staff on cloud technologies and managing organizational change (acknowledging a temporary productivity dip during the learning curve).
CIOs who evaluate these cost categories upfront can build more accurate budgets and avoid nasty surprises mid-project. Thirty-five percent of businesses admit they overlooked secondary costs like integration or training in their cloud planning. A holistic TCO evaluation in the RFP and planning phase ensures proposals reflect reality and set proper expectations. With a comprehensive view from the start, cloud migration stops being a leap of faith and becomes a well-budgeted strategy with clear business value targets.

Hidden costs, such as integration and downtime, can undermine expected cloud savings
On paper, moving to the cloud often promises cost savings, but unplanned expenses can quickly chip away at those savings. Many CIOs discover hidden costs in areas like integration complexity, performance issues, or downtime that weren’t anticipated in the initial budget. Fifty-eight percent of organizations say their cloud costs have become a “black hole” of unknown charges, and 56% have experienced surprise spikes in cloud bills due to unforeseen usage. These overlooked factors can undermine the ROI of a cloud migration if not addressed early.
Integration and interoperability
Migrating applications to the cloud often uncovers unforeseen integration challenges. Systems that once ran on-premises may require new APIs or middleware to connect properly with other applications. This extra integration work can consume significant time and budget, especially if legacy systems need changes to work smoothly with cloud services. Without planning for these efforts, integration costs can balloon and delay the benefits of migration.
Downtime and disruption
Cloud migrations often entail some scheduled downtime or performance slowdowns, and any unplanned outage can be costly. Even a brief disruption in a critical system may lead to lost revenue, reduced employee productivity, or harm to customer trust. Organizations frequently underestimate the expense of maintaining business continuity (such as running parallel systems) to mitigate these risks. If such precautions aren’t budgeted, the financial impact of downtime can erode the expected savings.
Legacy refactoring and technical debt
Lifting a poorly optimized application into the cloud can lead to sticker shock. Legacy systems with inefficient code or architecture may consume far more cloud resources than anticipated. Organizations sometimes find they must refactor or modernize these applications to reduce cloud costs by paying down technical debt. This unplanned reengineering adds to the migration cost and can delay the realization of the cloud’s promised cost savings.
Unaddressed, these hidden costs will erode the expected financial gains of cloud migration. CIOs should proactively budget for such factors as standard line items in their TCO analysis, rather than treat them as one-off exceptions. This diligence ensures cloud migrations deliver on anticipated savings and strategic objectives instead of becoming costly lessons learned.
A multi-year perspective is essential to gauge cloud migration’s true ROI

Short-term cloud cost comparisons can be misleading. The first year of a migration might include one-time expenses for rearchitecting and data transfer, while subsequent years incur steady operational charges for cloud services. Without a multi-year outlook, CIOs might declare victory too early or fail to anticipate rising usage costs later. It’s also vital to continuously optimize cloud resources over time. Companies on average waste roughly 32% of their cloud spend on idle or mis-provisioned resources, a drain that underscores the need for vigilant cost management.
Looking at a three- to five-year period provides a much clearer picture of return on investment. Upfront migration costs should be amortized over several years against the ongoing efficiency gains and innovation enabled by the cloud. For example, one analysis found organizations typically realize about $2.12 in value for every $1 spent on cloud services over three years. This kind of multi-year ROI assessment resonates with executives and boards, giving them hard numbers to justify the cloud move. It also encourages IT teams to plan beyond the go-live date by building in cost governance and regular cost reviews to ensure the cloud environment continues to deliver value year after year.
Cloud spend becomes a value driver when aligned with business goals
Cloud costs should not be viewed in a vacuum. When CIOs tie cloud spending directly to business objectives (such as accelerating product delivery, improving customer experiences, or expanding into new markets), that spending turns into an investment fueling growth. In practice, this means collaborating with the CFO and business unit leaders to define how cloud initiatives will impact key metrics. Notably, 77% of executives say cloud scalability is critical to business growth, underscoring that the right cloud investments can drive revenue and competitive advantage rather than just IT efficiency.
This alignment elevates discussions about cloud from “What does it cost?” to “What value does it deliver?”. For example, a company might justify higher cloud spending because it enables launching a new digital service faster, capturing market share, and generating new revenue. By mapping cloud projects to specific outcomes, such as shortening supply chain cycles or enabling real-time data insights, IT leaders can demonstrate tangible business value. Cloud spend, managed with clear goals and KPIs, becomes a lever for innovation and agility that resonates in the boardroom. Cloud budgets gain strong support when every dollar is linked to a strategic outcome.
