When a data error appears, someone may patch a spreadsheet, reconcile two reports by hand, or add an exception to a workflow so the work can continue. The output looks usable, but if the source problem survives, the same correction returns next cycle. The hidden cost is not just cleaning the data once: it is the repeated labor, delay, risk, and system complexity that can build around an unresolved cause.
How dirty data turns into recurring cost
Dirty data is inaccurate, incomplete, inconsistent, outdated, duplicated, or otherwise unsuitable for a particular use. It can generate direct costs—detection, analysis, remediation, scrap, rework, workarounds, hidden corrections, and compliance fines—as well as indirect costs such as delay and inefficient use of staff time. The burden is easy to miss when correction work is distributed across analysts, operations teams, and spreadsheets rather than tracked as a formal project.

A common cycle is straightforward: an error is found, a person corrects it for the immediate report or transaction, and the result is delivered. If the source process, data definition, system, or ownership problem is unchanged, the next user encounters the same issue. A local fix can be sensible during an incident; it becomes a management concern when it repeats without an owner, review, or route to resolve the cause.

- Find and repair: Someone has to detect the problem, establish which value is right, and correct the record or output.
- Repeat the workaround: Manual reconciliation, spreadsheet rules, and one-off exceptions consume time each time the data is reused.
- Delay or rework: Teams may wait for a correction, redo downstream work, or reconcile conflicting versions before proceeding.
- Risk weaker decisions: If users cannot tell which data is reliable, they may make decisions from incomplete or inconsistent information.
- Constrain future changes: Once exceptions become embedded in reports, interfaces, or operating routines, changing a system or process may require finding and preserving those hidden rules.
IBM describes legacy data models and brittle interfaces as factors associated with technical debt and manual workarounds. That is useful as a vendor explanation of how the pattern can develop, not a universal measurement of its effects. IBM’s overview of dirty data provides that framing.

When workarounds become technical debt
Technical debt is an analogy for the future burden created by compromises and constraints, not a standardized balance-sheet figure. A temporary manual fix can keep a process running. The debt accumulates when the workaround becomes routine, undocumented, or intertwined with systems and decisions, making the original cause harder to see and future changes more difficult.
Not every data error is systemic. A one-time event—such as a migration—may produce a limited cluster of bad records that can be corrected without redesigning an ongoing process. A recurring pattern across reporting cycles, teams, or transactions suggests a cause that may need action beyond cleanup. The UK Government’s Data Quality Action Plan Implementation Guide recommends distinguishing one-off issues from systemic ones and investigating root causes rather than treating symptoms.

Measure your organization’s exposure
There is no single universally reliable figure for the cost of bad data. Published figures can show why the issue merits attention, but they describe particular research or models and should not be treated as a forecast for an individual organization.
| Source and context | Reported figure | How to interpret it |
|---|---|---|
| Deloitte, 2026 Global Technology Leadership Study, as reported in its 2026 technical-debt analysis | 21% to 40% of an organization’s IT spending | Deloitte uses the midpoint as a model baseline and says technical debt has no standard benchmark. It is not a universal accounting measure. Deloitte’s analysis. |
| Deloitte, 2026 data-capability model scenario | A 35% increase in data capability, implemented gradually over 18 months, was associated in the model with relative technical-debt reductions of 1.3% by year two, 3.2% by year three, 5.3% by year four, and 7.1% by year five, compared with an average organization. | These are modeled scenario outputs, not observed savings or guaranteed results for a particular company. Deloitte also modeled 52.5% less latent potential by year five in the organization that improved data capability; its analysis defines lower latent potential as less value hidden by technology complexity. Deloitte’s analysis. |
| McKinsey, 2019 article on reducing data costs | 5% to 15% potential short-term annual data-spend reduction | This is an estimate for targeted changes to sourcing, architecture, governance, and consumption—not a guaranteed saving. McKinsey’s article. |
| McKinsey, 2019 article, reported research estimates in a particular context | 30% to 40% of time searching for data; 20% to 30% cleansing data | These estimates should not be generalized to every organization or used as a local labor-cost calculation. McKinsey’s article. |
For a local baseline, track both direct spending and indirect labor spent on data management, remediation, and manual reporting. Include the recurring correction and reconciliation time that is often hidden in everyday work. The UK guide recommends assessing data quality against its purpose and users’ needs; it also advises measuring the organization’s own costs rather than relying on broad estimates.

A practical way to find and prioritize root causes
Start with a critical data asset and one recurring problem rather than launching a generic cleanup. Define the quality needed for the asset’s actual use: a field that is essential for one decision may be less important for another. Then rank issues by business importance, impact, and risk, as well as the cost and feasibility of addressing them.
- Define the use and acceptable quality. Identify who relies on the data and what decision or process it supports. Set the relevant quality criteria for that use rather than assuming every field needs the same standard.
- Separate isolated events from recurring patterns. Check whether the issue traces to a one-time event, such as a migration, or appears repeatedly across records, teams, or reporting cycles.
- Rank the issue. Consider business impact, risk, the labor and delay created by the current workaround, the likelihood a fix will prevent recurrence, cost, and feasibility.
- Name an accountable owner and target timeframe. Record the action, owner, target date, and review date. An issue without an owner can remain in the gap between teams that use data and teams that create it.
- Investigate the cause before selecting a fix. Determine whether the driver is a process, standard, validation rule, storage practice, automation gap, system constraint, training need, or unclear ownership.
- Choose and implement a cause-level change. Select the response that fits the cause; cleaning records alone will not correct a broken source process or an ambiguous definition.
- Monitor whether the issue recurs. Review the result on the agreed date, report progress, and check whether manual correction and reconciliation have actually declined.
The UK Government’s guide puts the principle plainly: “Cleaning bad data is only cost effective if you address the root cause first.” It also says: “Evaluate data quality based on its specific use, recognising that importance may vary.” Those statements support a practical distinction: clean what is necessary for the use, then change what keeps recreating the problem.

Deciding whether to keep, contain, or remove a workaround
A useful decision is not simply whether a workaround is inelegant. Compare its ongoing burden and risk with the cost and likely effectiveness of a durable fix. A time-limited workaround may be the right choice while a system is stabilized or a larger change is planned; it should still have a named owner, a review point, and a clear path to resolution.
- Keep temporarily when the immediate operational benefit outweighs the short-term burden and the workaround is documented, controlled, and reviewed.
- Contain and investigate when the underlying cause is uncertain, but errors or manual corrections recur and could affect downstream users.
- Fund a cause-level fix when repeated labor, delay, or risk is material and a feasible process, standards, validation, storage, automation, system, or training change is likely to prevent recurrence.
When a proposed program includes modeled benefits, keep those separate from measured outcomes. Deloitte’s 2026 analysis combines surveys, interviews, and a system-dynamics model; its scenario results depend on the modeled assumptions and horizon. They are not a promise of an individual organization’s savings. Deloitte explains its approach and scenarios.
What to do next
Choose one critical data asset and measure the recurring time spent correcting or reconciling it. Identify who owns the source process, distinguish an isolated incident from a repeated cause, and compare the cost and risk of a durable fix with continued workarounds. That gives leaders a concrete basis for deciding whether to maintain a temporary patch or reduce the debt at its source.
