The note focuses on practical steps: defining the SME population, choosing the measurement concept, using South African data sources, and reporting a range with transparent assumptions. Readers who only need a short headline can read the quick answer section; those preparing an estimate should read the step-by-step framework and reconciliation guidance.
Quick answer and how to use this article
Short headline answer, contribution of small business to the south african economy
The short answer is that there is no single, routinely published official percentage that states the contribution of small business to the south african economy for 2024 to 2026. Estimates that focus on SMME surveys and administrative proxies commonly land in an indicative range, but the exact number depends on whether analysts use value added or turnover, which firm-size cutoffs they choose, and whether informal microenterprises are included. For the official value added totals to start from, see the Stats SA national accounts release for the latest published figures Stats SA national accounts.
Spreadsheet checklist for deriving an SME GDP share
Use this to ensure consistent reporting
Use this opening section to decide whether you need a quick, indicative range or a detailed method-driven estimate. If you need a short headline for reporting, read the first paragraph and the worked examples. If you plan to produce an estimate with defensible documentation, skip to the step-by-step framework and the reconciliation guidance.
What we mean by small business in this context
Definitions matter. Analysts and policymakers use several firm-size cutoffs to label micro, small and medium enterprises, and those choices change which firms are counted as small business. Common practice in South African SMME work is to group businesses into micro, small and medium categories based on employment, turnover and sometimes asset thresholds. International guidance and survey projects use slightly different cutoffs, so a single label can cover different firm populations depending on the source.
When a source includes informal microenterprises the counted population expands a great deal. Informal microenterprises tend to have low measured value added, but they are numerous and often significant for employment. That means whether a measure includes or excludes informal firms alters the estimated SME share of GDP substantially. For cross-study comparability, always note whether the definition is employment-based, turnover-based or a combined SMME definition.
To give a concrete framing, a practical working approach is to state the exact cutoff used when you say small business. For example, an analyst might define small business as firms with fewer than 50 employees, or as the combined set of micro, small and medium enterprises used in a given survey. Make the cutoff explicit and document the dimension used, because the chosen rule determines the numerator when computing any SME share of GDP.
Official statistics landscape in South Africa
Stats SA publishes national accounts and official value-added totals by industry, but it does not routinely publish an SME-level value-added series. See Measuring South Africa’s Economic Growth. Producing a percent of GDP for small business therefore requires linking firm-size data from registers or microdata to the national accounts structure, or constructing a survey-based proxy that is scaled to national totals Stats SA national accounts.
Because the national accounts give the denominator in standard GDP-style reporting, the usual sequence is to take the official value added totals by industry from Stats SA and then estimate how much of that industry value added was produced by firms within the chosen size bands. That requires either business register linkage or microdata with firm-size indicators. Without that linkage, analysts who publish SME shares are typically using survey or administrative approximations and must state that clearly.
If you want to reproduce a transparent SME share, start from the official published value added series and then document how you derived the numerator. Where possible, derive the numerator from Stats SA microdata or DTIC administrative linkages so the estimate can be replicated and compared to the national accounts base. See the contact page.
Measurement choices that change the result
Measurement choices are the major reason published SME-GDP figures vary. The conceptual difference between value added and turnover is key: GDP is a value-added concept, so an estimate based on value added aligns with GDP by design, while a turnover-based estimate can overstate the economic contribution if it is not adjusted to remove intermediate consumption. International guidance emphasises this distinction and warns that mixing concepts reduces comparability across studies World Bank country overview.
Including informal microenterprises typically raises an estimate of small business contribution when measured on a turnover basis and can change the distribution of employment and value added in important ways. However, informal firms often report limited or no formal accounting, so survey-based counts require clear caveats about coverage and measurement quality. For these reasons, analysts usually present ranges and sensitivity checks rather than a single point figure.
Join the conversation on economic policy and research
For a step-by-step method and worked examples, see the framework section below and the example calculations later in this article.
International organisations also note that the firm-size cutoffs you select matter. Counting firms with up to 250 employees will produce a very different SME share than counting firms with up to 50 employees. The inclusion rule changes both the numerator composition and the policy message you can support with the number OECD country note.
Data sources you can use in South Africa
Main sources used to construct SME-GDP estimates are the Stats SA national accounts for official value-added totals, DTIC and SEDA publications for policy-focused analyses and administrative proxies, and survey projects such as FinScope for microenterprise coverage and behaviour. Each data source has strengths and limits that affect how you should use it in an estimate DTIC SMME policy and data sources. Other relevant analyses include the IFC MSME finance gap report IFC MSME Finance Gap.
Survey sources such as FinScope provide household and small business level detail and are especially useful when you need to capture informal and microenterprise activity. FinScope data show patterns of small business participation and employment that are not visible in administrative records, but any survey-based numerator will usually need scaling to match national accounts totals FinScope small business survey.
A practical step-by-step framework to estimate the SME share of GDP
Step 1. Decide your measurement goal. Choose whether you aim to estimate value added for an SME population, or a turnover-based proxy. For GDP alignment, prefer value added. State the year, the exact firm-size cutoffs, and whether informal firms are included. This framing sets the reader expectation and determines which data sources are appropriate.
Step 2. Choose your data sources. Use Stats SA national accounts for the denominator value added totals and select a source for firm-size information. Options include linking Stats SA microdata, using DTIC or SEDA administrative breakdowns, or constructing a denominator-scaled survey proxy from FinScope or similar surveys. Document the choice and the coverage limitations.
Step 3. Construct the numerator. If microdata linkage is available, map firms by industry and size to the national accounts structure and aggregate their value added for the defined size bands. If only survey data are available, build a turnover or value-added proxy and scale it so the total industry amounts align with the official national accounts totals. Always show the scaling factor and the assumptions used.
Step 4. Report a method-defined range. Because choices matter, present a low and high bound that reflect plausible alternative cutoffs and inclusion rules. For example, report separate lines for an estimate excluding informal microenterprises and an estimate including them. Provide clear metadata: year, measurement concept, firm-size cutoffs, data sources, and any scaling applied. Where possible, derive the range from microdata or DTIC/SEDA administrative linkages for transparency DTIC SMME policy and data sources.
These steps make the estimation replicable. Analysts should also provide sensitivity checks by showing how the SME share moves when the firm-size cutoff shifts or when turnover-based proxies are used instead of value added.
Employment versus GDP: interpreting different policy questions
SMEs commonly account for a larger share of jobs than of GDP. Employment-based proxies therefore paint a different picture from value-added-based GDP shares. If the policy question is about jobs, an employment share is appropriate; if it is about value creation and economic output, value added is the right metric. FinScope surveys and SEDA summaries highlight this distinction for South Africa and suggest analysts use both metrics when appropriate FinScope small business survey.
Using the wrong metric for the policy aim is a common source of confusion. For example, a program that targets job creation should be assessed with employment measures rather than a headline SME share of GDP, because interventions that raise employment may not raise measured value added per worker. Conversely, productivity or competitiveness policies should focus on value added and productivity indicators rather than job counts.
When presenting results, include both the SME share of employment and the SME share of value added where possible. This dual presentation helps readers and policymakers see the tradeoffs and choose interventions that match their objectives, whether that is job quality, income growth, or aggregate output.
Worked examples: published estimates and how they were derived
Example A. SEDA summary estimates. SEDA publishes policy-oriented analysis that often places SME contributions in an indicative range of roughly 30 to 35 percent when using aggregated SMME survey or administrative proxies. The SEDA summaries are useful for understanding how survey and administrative approximations produce an indicative range, but the reports emphasise the caveats about definitions and measurement choices SEDA analysis.
Example B. FinScope-based proxy estimates. FinScope provides survey-based counts that include informal microenterprises. When analysts use FinScope data and scale to national accounts, the inclusion of many small informal firms typically raises the estimate relative to a strictly registered-firm value-added approach. The FinScope documentation explains coverage and survey methods, which helps analysts judge when a FinScope-based proxy is appropriate and how to adjust it for national totals FinScope small business survey.
Both example paths show why the 30 to 35 percent statements are best read as indicative ranges rather than precise, universally comparable statistics. The exact figure will depend on whether you use value added or turnover, the firm-size cutoff, and whether you include informal firms.
How to reconcile survey and national-accounts estimates
Reconciling survey totals and national accounts requires explicit mapping and scaling. A common first step is to map the survey industry categories to the national accounts industry codes so the two data sources are speaking the same language. After mapping, scale the survey-based totals so that the aggregated industry value matches the official national accounts value for the same year.
There is no single routine official percentage; reasonable, method-defined estimates commonly fall in an indicative range and must be reported with clear method notes and uncertainty.
Common adjustments include correcting for survey undercoverage, removing double counting across overlapping survey instruments, and documenting which informal activities are excluded from national accounts. Analysts should present the scaling factors used and test how sensitive the SME share is to reasonable alternative scalings Gross domestic product, First quarter 2025.
Documenting assumptions is essential. Provide a table with the numerator construction, the denominator source, the scaling factors and notes on coverage gaps. This transparent record allows readers and peer reviewers to follow the chain of adjustments and to reproduce the reported range. See the about page for author context.
Typical pitfalls and how to avoid them
Misreading turnover as value added is a frequent mistake. Turnover is not the same as value added because it includes intermediate consumption. If you use turnover without adjustment you risk overstating the contribution to GDP. To avoid this, prefer value added or, if using turnover, apply an industry-level factor to convert turnover to value added.
Another typical error is failing to disclose firm-size definitions. If you report a single point estimate without stating the cutoff for small business, readers cannot judge whether the number is comparable to other studies. Always show the firm-size cutoffs used and, if possible, include alternative cutoffs in a sensitivity table.
Also beware of survey coverage gaps in the informal sector. Surveys that appear to count many microenterprises may still miss hidden activity. Be explicit about coverage limitations and include uncertainty bounds rather than presenting a definitive single figure.
How to present results: ranges, methods and uncertainty
Recommended reporting format. Always present a method-defined range with metadata: the year, whether the estimate is value added or turnover-based, the firm-size cutoffs, the data sources, and any scaling applied. A single-sentence template is useful, for example: “Using Stats SA value added as the denominator and firm-level microdata to define firms with fewer than 50 employees as small business, the estimated SME share of GDP for 2024 is X to Y percent, where X excludes informal microenterprises and Y includes them.” Cite the primary sources used for the numerator and denominator.
Suggested visualisations include a range bar that shows low and high estimates, a sensitivity table that reports the SME share under alternative cutoffs, and a short table that lists the numerator method, denominator, and scaling factors. These visuals make assumptions visible and help readers compare studies that use different methods DTIC SMME policy and data sources.
When in doubt, err on the side of transparency. Provide the spreadsheet or code used to produce the scaled estimates where possible, and always label estimates as derived rather than as official national statistics unless they have been produced by a national accounts linkage exercise.
Policy implications: what SME-GDP shares can and cannot tell you
SME-GDP shares indicate the relative share of value creation by firms below a chosen size threshold, but they do not by themselves show distributional or welfare effects. A high SME share of GDP can coexist with low average incomes for small business owners or with wide regional differences in firm productivity. Use complementary indicators such as firm-level productivity, household income and employment outcomes to interpret the number World Bank country overview.
For job-focused policy, employment metrics are the right lens. If the goal is to increase employment, the SME share of jobs and measures of job quality are more relevant than the SME share of value added. For productivity or output policy, value added and productivity per worker are the right indicators. Combine metrics to get a fuller picture before proposing interventions.
Finally, account for measurement uncertainty in decisions. Present scenario-based outcomes rather than definitive claims about policy effects that rely on a single SME-GDP number. That cautious framing protects decision making from being driven by a particular measurement choice.
Short checklist for journalists and analysts
Top checks before publishing a number. 1) State whether the estimate uses value added or turnover. 2) Show the year and the firm-size cutoffs. 3) List the data sources and whether the numerator was scaled to national accounts. 4) Provide an uncertainty range and note key caveats. These five checks help avoid common reporting errors Stats SA national accounts.
Questions to ask of a data source. Does the survey capture informal microenterprises? Has the survey been scaled to match national accounts? Are industry mappings available? If the answers are unclear, postpone publishing a single point estimate and present a range instead. Linking to primary sources such as the Stats SA release, SEDA notes or FinScope documentation helps readers verify the basis of your figure.
Conclusion: clear communication beats a single number
No single official SME-GDP percentage exists in routine national publications for 2024 to 2026. Analysts and journalists should prefer method-qualified ranges, state the measurement concept and firm-size cutoffs, and use Stats SA value added as the reference denominator when the goal is GDP alignment. This practice improves transparency and comparability. See the Michael Carbonara homepage.
Choose the appropriate metric for the policy question, present sensitivity checks, and avoid definitive policy claims that rest on a single derived percentage. Clear method disclosure and accessible supporting materials make the reported SME share more useful for research and decision making.
Report a short, method-qualified range and state the year, whether you used value added or turnover, the firm-size cutoffs, the data sources, and any scaling to national accounts.
Use value added to align with GDP. If you must use turnover, convert it to a value-added proxy and document the conversion method and assumptions.
Numbers vary because studies use different measurements, firm-size definitions, and coverage of informal microenterprises; these choices change both numerator and denominator and produce different results.
When in doubt, use Stats SA value added as the denominator and complement any SME-GDP estimate with employment and productivity indicators to inform policy.
