Financial Literacy and Small Business Profitability in Nigeria: What Lagos Entrepreneurs Need to Know

Background to the Study

Small businesses occupy an outsized role in Nigeria's economic structure. Data from the National Bureau of Statistics (NBS, 2021) shows that micro, small, and medium-sized enterprises make up roughly 96% of all businesses in the country, generate about 48% of national GDP, and employ close to 84% of the working population. Yet this economic weight sits uneasily alongside a troubling survival rate: SMEDAN (2021) estimates that between 60% and 80% of new small businesses in Nigeria fail within their first five years. Poor financial management is repeatedly cited as one of the central reasons behind this pattern — a problem that, at its root, reflects a lack of financial literacy.

Financial literacy, broadly defined, is a person's ability to understand and apply financial management principles to personal and business decisions. Lusardi and Mitchell (2014) describe it as the knowledge and capability required to make informed, effective choices about managing financial resources. For small business owners, this translates into practical competencies — basic bookkeeping, cash flow management, reading financial statements, tax compliance, budgeting, and understanding available credit and financing options. These are not abstract academic skills; they shape a business's day-to-day operational capacity and its ability to generate and retain profit.

Global interest in the link between financial literacy and business performance intensified after the 2008 financial crisis, which laid bare the costs of financial ignorance at both individual and institutional levels. Adomako, Danso, and Ofori Damoah (2016) found financial literacy to be a strong predictor of firm performance among Ghanaian entrepreneurs, while Fatoki (2014) reported similar patterns among South African SMEs. Closer to home, Oluwole and Akintola (2019) observed that most Nigerian small business operators lack fundamental financial management skills, and that this shortfall is closely tied to weak profitability, heavy reliance on informal credit, and eventual business failure.

Nigeria's economic environment adds further texture to this discussion. With a population above 220 million, a predominantly informal economy, high youth unemployment, and a financial sector that has historically underserved small enterprises, the country presents both real obstacles and real opportunities for financial literacy development. The Central Bank of Nigeria has responded through initiatives such as the National Financial Inclusion Strategy (NFIS), which targets 95% financial service access among adult Nigerians by 2024. However, as Demirguc-Kunt, Klapper, Singer, Ansar, and Hess (2018) point out, access to financial services means little without the literacy to use those services effectively.

Lagos State, the focus of this study, offers a particularly rich setting for this research. As Nigeria's commercial capital and one of Africa's fastest-growing cities, Lagos hosts the country's densest concentration of small businesses. The Lagos State Employment Trust Fund (LSETF, 2022) reports more than two million registered MSMEs in Lagos alone, alongside a substantial but uncounted number of unregistered enterprises spanning retail trade, food and beverage, fashion, information technology, transportation, and artisanal work. This diversity makes Lagos an ideal setting for examining how financial literacy — or its absence — shapes business outcomes across different sectors.

Several Nigerian studies point to specific gaps in financial understanding among small business owners. Eniola and Entebang (2017) found that many SME owners in Nigeria mix personal and business finances, keep poor records, rarely prepare or read financial statements, and remain largely unaware of formal financing options. These gaps do more than dent profitability directly — they also limit a business owner's ability to attract investment, secure credit, manage risk, and plan strategically for growth. Add to this the structural pressures Nigerian small businesses already face — unreliable power supply, infrastructure gaps, currency volatility, and an unpredictable regulatory landscape — and strong financial management becomes an even more essential buffer against external shocks.

The COVID-19 pandemic exposed these vulnerabilities starkly. The NBS (2020) COVID-19 Business Impact Survey found that more than 60% of small businesses in Nigeria experienced significant revenue declines, with many unable to sustain operations beyond three months due to weak financial reserves and poor cash flow management — both classic symptoms of financial illiteracy. The pandemic effectively functioned as a stress test, revealing just how much financial literacy gaps can threaten business survival during periods of economic shock.

Even with a growing body of international literature on financial literacy and SME performance, notable gaps remain in Nigerian research. Many existing studies are narrow in scope, sector-specific, or rely heavily on qualitative approaches. There is also a need for updated empirical evidence reflecting the post-pandemic economic realities facing Nigerian entrepreneurs. This study responds to these gaps by offering a quantitative assessment of how the different dimensions of financial literacy affect the profitability of small business owners in Lagos State.

Statement of the Problem

Despite their numerical dominance and significant contribution to the Nigerian economy, small businesses continue to underperform relative to their potential. Nigeria's small business survival rate ranks among the lowest in Sub-Saharan Africa, with most enterprises collapsing within three to five years of operation (SMEDAN, 2021). While factors such as policy instability, inadequate infrastructure, and restricted access to capital are commonly cited explanations, financial illiteracy is increasingly recognised as an underlying — and often primary — cause.

A significant share of small business owners in Nigeria operate without formal financial records, cannot interpret basic financial statements, do not prepare business budgets, and remain unaware of their tax obligations (Eniola & Entebang, 2017; Oluwole & Akintola, 2019). These are not minor oversights. Poor record-keeping makes it nearly impossible to track profitability with any accuracy, meaning some business owners may be losing money without realising it. An inability to prepare or interpret financial statements leaves owners unable to assess performance or plan strategically. The absence of budgeting exposes businesses to sudden cash flow crises, while tax non-compliance introduces avoidable regulatory risk.

The problem deepens further because most small business owners in Nigeria rarely seek professional financial advice, whether due to cost concerns or simple unawareness of available services. Many instead lean on informal guidance from family members or fellow traders — advice that may be well-meaning but is seldom grounded in sound financial principles. The cumulative result is a sector marked by chronic underperformance, frequent business closures, and lost economic potential, both for individual entrepreneurs and the wider economy.

While studies elsewhere in Africa have established a link between financial literacy and business success (Adomako et al., 2016; Fatoki, 2014), rigorous, quantitative research examining this relationship specifically among small business owners in Lagos remains relatively scarce. This study addresses that gap by generating empirical evidence on how specific financial literacy dimensions — including bookkeeping practices, budgeting behaviour, financial statement comprehension, credit access and management, tax awareness, and investment decision-making — affect profitability among small business owners in the study area.

Aim and Objectives of the Study

The broad objective of this study is to examine the impact of financial literacy on the profitability of small business owners in Nigeria. To achieve this, the study pursues the following specific objectives:

•      1. Assess the level of financial literacy among small business owners in Lagos State, Nigeria.

•      2. Determine the effect of financial record-keeping practices on the profitability of small business owners in Lagos State.

•      3. Examine the relationship between budgeting behaviour and business profitability among small business owners in Lagos State.

•      4. Investigate the impact of access to credit and credit management skills on business profitability among small business owners in Lagos State.

•      5. Determine the influence of tax literacy on the compliance and profitability of small business owners in Lagos State.

Research Questions

The study is guided by the following research questions:

•      1. What is the level of financial literacy among small business owners in Lagos State?

•      2. To what extent do financial record-keeping practices affect the profitability of small business owners in Lagos State?

•      3. What is the relationship between budgeting behaviour and business profitability among small business owners in Lagos State?

•      4. How does access to credit and credit management skills impact the profitability of small business owners in Lagos State?

•      5. What is the influence of tax literacy on the compliance and profitability of small business owners in Lagos State?

Research Hypotheses

Based on the research questions and existing literature, the following null hypotheses were tested:

•      H0₁: Financial record-keeping practices have no significant effect on the profitability of small business owners in Lagos State.

•      H0₂: Access to credit and credit management skills have no significant impact on the profitability of small business owners in Lagos State.

Significance of the Study

This study carries relevance across several dimensions — policy, practice, theory, and community impact.

Policy Significance

From a policy standpoint, the findings are directly relevant to government agencies and regulatory bodies such as the Central Bank of Nigeria (CBN), the Small and Medium Enterprises Development Agency of Nigeria (SMEDAN), and the Nigerian Investment Promotion Commission (NIPC), all of which play a role in designing interventions to support SME growth. By pinpointing the specific dimensions of financial literacy that most strongly influence profitability, the study offers a foundation for more targeted, evidence-based policymaking.

Practical Significance

For practitioners — including commercial banks, microfinance institutions, and development finance institutions — the study sheds light on the financial capability gaps present among their small business clients. This understanding matters for designing loan products, advisory services, and financial education programmes that genuinely match the needs of small business owners rather than assuming a one-size-fits-all approach.

Theoretical Significance

For academic researchers, the study adds to the expanding body of literature on financial literacy and SME performance in Sub-Saharan Africa. Its quantitative approach and its disaggregation of financial literacy into measurable, distinct dimensions provide a framework that other researchers can replicate or build upon in future studies.

Community Significance

For the small business owners at the heart of this study, the findings can ultimately be translated into practical educational resources that help them better understand and manage their business finances — improving their odds of survival and long-term growth.

Scope of the Study

This study is geographically limited to Lagos State, Nigeria. Within the state, it focuses on small business owners registered with the Corporate Affairs Commission (CAC) or operating under Local Government Area (LGA) trader associations across five selected local government areas: Lagos Island, Alimosho, Oshodi-Isolo, Lagos Mainland, and Surulere. These LGAs were chosen for their high concentration of small business activity.

The study spans the period from 2019 to 2023, covering the pre-COVID, COVID, and post-COVID phases, which allows for a more complete picture of the financial literacy challenges facing small business owners across a period of significant economic disruption. In line with SMEDAN's classification of small enterprises, the study is restricted to small businesses with an annual turnover not exceeding ₦50 million.

Limitations of the Study

Several limitations shaped the conduct and interpretation of this study.

•      Cross-Sectional Design: As a cross-sectional survey, the study captures financial literacy and business performance at a single point in time, limiting the ability to draw firm causal conclusions or observe how changes in financial literacy affect profitability over time. A longitudinal design would have better supported causal claims but was not feasible within the constraints of an undergraduate project.

•      Self-Reported Data: The study relies on self-reported responses, which are susceptible to social desirability bias — respondents may overstate their financial knowledge or profitability to appear more competent or successful. Anonymity assurances and behavioural questions (assessing what respondents actually do rather than what they claim to know) were used to reduce this risk.

•      Geographic Limitation: The sample is drawn exclusively from Lagos State, which limits how far the findings can be generalised to other Nigerian states and geopolitical zones, where business environments and financial literacy levels may differ considerably. Future research should widen the geographic scope of enquiry.

Despite these constraints, the study yields useful insights consistent with comparable research in similar contexts, and its conclusions are appropriately framed to reflect the boundaries of the research design.

Operational Definition of Terms

•      Financial Literacy: The degree to which a small business owner possesses the knowledge and skills necessary to understand and effectively manage financial information relevant to their business operations, including bookkeeping, budgeting, financial statement analysis, credit management, and tax compliance.

•      Profitability: The ability of a small business to generate income in excess of its operating costs over a given period. In this study, profitability is assessed using respondents' self-reported measures of business revenue growth, profit margins, and business sustainability.

•      Small Business Owner: An individual who owns and manages a business enterprise with a workforce of between 1 and 49 employees and an annual turnover not exceeding ₦50 million, in line with the SMEDAN and NBS (2021) definition of small enterprises in Nigeria.

•      Bookkeeping/Financial Record-Keeping: The systematic recording of a business's financial transactions, including sales, purchases, expenses, and payments. In this study, it is measured by the frequency and method of recording financial transactions and the maintenance of formal accounts.

•      Budgeting: The process of preparing a financial plan that projects future revenues and expenditures. In this study, budgeting behaviour is assessed by whether business owners prepare formal budgets and use them to guide business decisions.

•      Access to Credit: The extent to which small business owners are able to obtain financing from formal sources (banks, microfinance institutions) or informal sources (cooperatives, family and friends) for business operations and expansion.

•      Tax Literacy: The level of awareness and understanding that small business owners possess regarding their tax obligations, applicable tax types, rates, and the process of filing returns with relevant tax authorities.

Conclusion

The evidence from Lagos State makes a compelling case: financial literacy is not a peripheral skill for Nigerian small business owners but a core determinant of whether their enterprises survive, stagnate, or thrive. With financial literacy explaining a substantial share of the variation in profitability, and specific weaknesses in record-keeping, budgeting, and tax compliance consistently surfacing across the sector, the findings point to clear, actionable priorities for entrepreneurs, financial institutions, and policymakers alike. As Nigeria continues to navigate a challenging economic environment, closing the financial literacy gap among small business owners stands out as one of the most practical, high-impact interventions available — one capable of strengthening individual enterprises while reinforcing the resilience of the broader economy.
