Introduction
Public spending is intended to improve people’s lives, but allocating funds does not guarantee that services will be delivered or that intended outcomes will be achieved. Understanding the connection between budgets, expenditure, service delivery and results is essential for effective public financial management.
Governments make choices about how to allocate limited resources across competing priorities. Budgets determine how much funding is available for healthcare, education, agriculture, infrastructure, social protection and other public services. They also communicate policy priorities and establish the financial framework within which public institutions operate.
Yet an approved budget is only the beginning of the process.
Funds may be allocated but not released on time. Released funds may not be fully spent. Expenditure may take place without producing the expected services. Services may be delivered without reaching the intended populations, and improvements in service delivery may not translate into better outcomes.
These distinctions matter because public financial performance cannot be understood through budget figures alone.
A government may increase expenditure on healthcare without achieving corresponding improvements in access or quality. A county may allocate more resources to agricultural extension but still struggle to reach smallholder farmers. An education budget may expand while learning outcomes remain uneven across locations and population groups.
In each case, the central question is not simply how much money was allocated or spent. It is how public resources were converted into services, who benefited and whether those services contributed to the intended results.
1. A budget is a starting point, not a result
Public budgets are important instruments of planning, accountability and resource allocation. They indicate the resources that governments intend to commit to particular functions, programmes and activities.
However, several stages separate an approved allocation from an actual public outcome.
A useful way to understand this process is through the relationship between budgets, expenditure, service delivery and results.
Budget allocation indicates the resources authorised or planned for a particular purpose.
Budget execution concerns how those resources are released, committed and spent during the financial year.
Outputs represent the goods and services produced through public expenditure, such as medicines supplied, classrooms constructed, extension visits conducted or patients treated.
Outcomes refer to changes in people’s circumstances, service access, behaviour or wellbeing that public interventions are intended to support.
Impact concerns broader or longer-term changes to which public interventions may contribute. Establishing causal impact requires evidence capable of distinguishing programme effects from other influences.
Consider a county government that increases its allocation for primary healthcare facilities.
The allocation demonstrates a financial commitment. Actual expenditure shows how much was spent. Records of staff availability, medicine supplies and patients served provide information about service delivery. Changes in service access, treatment continuity or health outcomes provide further evidence about performance.
These measures answer different questions.
A high budget allocation does not establish that the funds were spent efficiently. High expenditure does not establish that services were delivered effectively. Increased service delivery does not automatically establish that health outcomes improved.
A credible assessment of public spending must therefore examine the relationships between these stages rather than treating any one of them as a complete measure of success.
2. Understanding the budget execution gap
One of the first questions in public expenditure analysis is whether approved budgets translate into actual expenditure.
Budget execution is commonly assessed by comparing actual expenditure with the approved or revised budget. The resulting execution rate can help identify whether spending was broadly in line with financial plans.
For example, suppose a public programme has an approved budget of KSh 100 million and records actual expenditure of KSh 75 million.
Its expenditure execution rate would be:
[
\text{Execution rate} =
\frac{\text{Actual expenditure}}{\text{Approved budget}}
\times 100
]
[
= \frac{75}{100}\times100 = 75%
]
The programme has spent 75% of its approved budget, leaving a difference of KSh 25 million between the allocation and recorded expenditure.
This calculation is straightforward, but interpreting it requires care.
A low execution rate may reflect delayed fund releases, procurement bottlenecks, staffing shortages, unrealistic budget estimates or weak implementation capacity. It may also reflect savings, changes in priorities or activities that were no longer necessary.
Similarly, a high execution rate is not necessarily evidence of good performance. Spending an entire allocation without achieving the intended outputs may indicate inefficiency, poor planning or weak accountability.
Execution rates should therefore be treated as diagnostic indicators rather than standalone measures of effectiveness.
Analysts should examine which budget lines were under- or overspent, when funds became available, what activities were implemented and whether expenditure patterns were consistent with programme objectives.
3. Follow the money from allocation to service delivery
Understanding public spending requires examining what happens between financial transactions and the delivery of services.
Several questions are useful.
Were funds released according to the planned schedule? Were procurement processes completed in time? Were goods and services delivered as intended? Were staff and operational resources available? Did the expenditure reach the facilities, communities or beneficiaries for whom it was intended?
Consider an agricultural extension programme designed to improve smallholder farmers’ access to technical advice.
A budget review may show that funds were allocated for extension services and that a substantial proportion was spent. However, expenditure records alone cannot establish whether farmers received the intended services.
Further evidence may be needed on the number and distribution of extension officers, the frequency of farm visits, the locations reached, the relevance of advice provided and the availability of complementary inputs.
If the programme records substantial expenditure but limited farmer coverage, the problem may lie in staffing, transport, operational planning or the geographic distribution of resources.
If coverage is high but adoption of recommended practices remains low, further investigation may be needed into the relevance of the advice, affordability of inputs, market incentives or other constraints.
This illustrates why expenditure analysis is more useful when linked to operational and programme data. Financial records reveal how resources were used; service delivery information helps explain what those resources produced.
4. Examine whether spending produces meaningful outcomes
The ultimate purpose of many public programmes is to improve social and economic conditions. This means that assessments should go beyond financial execution and service delivery to examine the outcomes that public spending is intended to support.
Suppose a government invests in expanding access to primary education.
Relevant evidence may include the number of classrooms constructed, teachers deployed and learning materials supplied. However, the intended objectives may also include improved school participation, reduced inequalities in access and better learning outcomes.
These results may not move together.
Constructing additional classrooms may improve physical access, but overcrowded schools could persist if enrolment grows faster than capacity. Increasing teacher numbers may not improve learning sufficiently if teacher deployment is uneven or instructional support is inadequate.
Moreover, outcomes are influenced by factors beyond the budget being examined. Household circumstances, infrastructure, demographic changes, local economic conditions and other policies can affect results.
For this reason, a public expenditure review should not assume that a change in spending directly caused a change in outcomes.
Descriptive analysis can establish how expenditure and outcomes changed over time. Comparisons across locations may identify differences in spending patterns and service performance. More rigorous causal evaluation may be necessary when decision-makers need to establish whether a particular intervention produced the observed change.
The appropriate analytical approach depends on the question, the available data and the consequences of the decision.
5. Efficiency and equity matter alongside spending levels
Public expenditure analysis should examine not only how much money was spent and what results followed, but also how efficiently and equitably resources were used.
Economy concerns whether inputs of an appropriate quality were acquired at a reasonable cost.
Efficiency examines the relationship between resources used and outputs or outcomes produced.
Effectiveness concerns the extent to which intended objectives were achieved.
Equity examines how resources, services and benefits are distributed across different groups and locations.
These dimensions are related, but they are not interchangeable.
A programme may purchase supplies at low cost but fail to reach the intended beneficiaries. Another may deliver services efficiently in urban areas while remote communities remain underserved. A programme may achieve strong average outcomes while widening disparities between population groups.
For example, two counties may spend similar amounts per resident on a particular service but achieve different levels of coverage. Those differences may reflect procurement practices, geography, staffing, infrastructure, population needs or the way services are organised.
A simple comparison of expenditure per resident would not be sufficient to explain the difference.
Analysts need to consider the context in which resources are used, the needs of the populations served and the quality and accessibility of the resulting services.
Equity is especially important because aggregate indicators can conceal unequal access. National or county averages may improve while particular communities continue to experience serious service gaps.
Disaggregating expenditure and outcome data by location and relevant population characteristics can help reveal these differences and inform more responsive allocation decisions.
6. Connect financial and performance data
A major challenge in public expenditure analysis is that financial and service delivery information often sit in separate systems.
Budget documents may record allocations and expenditure by administrative or economic classification. Programme reports may record outputs and outcomes. Administrative databases may contain information about service users, facilities or geographic coverage.
Each source provides a partial view of performance.
Connecting them requires attention to definitions, reporting periods, geographic identifiers and the organisational units represented in the data.
For example, an analyst comparing health expenditure with facility-level service delivery must establish whether financial figures and service indicators refer to the same period and whether the expenditure can reasonably be linked to the facilities being compared.
Similarly, comparing county allocations with outcome indicators requires consideration of population size, service needs, cost differences and the responsibilities assigned to different levels of government.
Several practical steps can strengthen this analysis:
- Define the performance question. Determine whether the objective is to assess execution, service coverage, cost efficiency, equity or outcomes.
- Identify the relevant data sources. These may include approved budgets, expenditure reports, procurement records, administrative data and programme monitoring systems.
- Align definitions and periods. Confirm that financial and performance indicators are comparable.
- Assess data quality. Investigate missing records, inconsistent classifications, duplicate entries and unexplained differences.
- Examine relationships. Compare spending patterns with service delivery and outcome measures, taking account of relevant contextual factors.
- Investigate unexpected findings. Use interviews, document reviews or facility-level analysis to understand patterns that financial figures alone cannot explain.
- Translate findings into decisions. Identify whether the evidence points towards changes in allocation, implementation, procurement, targeting or performance management.
The objective is not to combine every available dataset. It is to connect the information needed to answer a defined public finance or policy question.
7. From budget reporting to evidence-informed decisions
The practical value of public expenditure analysis lies in how it informs decisions.
If a programme consistently underspends because funds are released late, the response may involve improving cash-flow planning, procurement scheduling or coordination between institutions.
If expenditure is high but service coverage remains low, managers may need to investigate staffing, distribution, operational costs or implementation bottlenecks.
If services are delivered but outcomes remain weak, the problem may require changes in service quality, programme design or complementary interventions rather than additional spending alone.
If resources are concentrated in locations with relatively strong service coverage while underserved areas receive insufficient funding, the evidence may support reviewing allocation formulas and distribution criteria.
These responses should be guided by the underlying causes identified through analysis, not by spending figures in isolation.
Evidence-informed budgeting also requires feedback between planning and implementation. Previous expenditure patterns, unit costs, service coverage and outcome data should inform future estimates and priorities.
This creates an opportunity to move beyond annual compliance reporting towards a more continuous process of learning and public resource management.
However, evidence does not remove political choices or competing priorities. Budget decisions also involve legal obligations, distributional objectives, institutional mandates and public preferences. Analysis can clarify the trade-offs and likely implications of different options, but it cannot replace legitimate decision-making.
8. A practical framework for reviewing public expenditure
Before drawing conclusions about whether a public programme is performing well, decision-makers can work through six questions.
1. What was the programme expected to achieve?
Identify the policy objective, target population and intended results.
2. What resources were allocated and spent?
Compare approved budgets, revised budgets, releases and actual expenditure where reliable information is available.
3. What services were delivered?
Examine the volume, quality, timeliness and geographic distribution of outputs.
4. Who benefited?
Assess whether services reached the intended population and whether access differed across locations or relevant groups.
5. What changed?
Examine the outcomes associated with the intervention and distinguish observed changes from effects that can credibly be attributed to the programme.
6. What should happen next?
Identify the operational, financial or policy changes that the evidence supports, including areas where further investigation is needed.
This framework can be adapted to national government programmes, county-level services, donor-funded interventions and public-sector reforms. The indicators and methods will vary, but the principle remains the same: financial inputs should be examined alongside implementation, service delivery and results.
Conclusion: Public spending should be judged by more than the money spent
Budgets reveal public priorities and establish the resources available for government action. Expenditure data show how those resources were used. Service delivery information reveals what was produced, while outcome evidence helps establish whether conditions changed in the intended direction.
None of these perspectives is sufficient on its own.
A credible assessment of public spending connects them, examines the context in which resources are used and recognises the limitations of the available evidence. It distinguishes financial compliance from operational performance, observed outcomes from causal effects, and aggregate progress from equitable access.
For governments, development partners and public institutions, this approach can strengthen budget planning, improve accountability and support more informed resource allocation.
