How to calculate human capital?
Human capital cannot be measured as precisely as financial elements like debt or equity, as it is closer in nature to intellectual capital. However, organisations that invest in their workforce often see measurable gains in productivity and profitability, allowing them to assess returns on investment over time. For instance, if employer-led training contributes significantly to an employee’s lifetime earnings, it reflects the strong value generated through such investments.
The main approaches used to estimate human capital include:
- Income-based approach: Calculates the present value of all future earnings an individual is expected to generate over their working life, adjusted to today’s terms.
- Cost-based approach: Estimates value by adding up all investments made in developing human capital, including education, training, and health-related expenses.
- ROI method: Measures the return generated from investments in training or education by comparing the resulting increase in productivity or earnings with the cost incurred.
- Ageing-of-receivables approach: Evaluates how the value of human capital may decline over time due to skill obsolescence, while also considering the need for continuous upskilling and retraining.
Determinants of human capital
Organisations can strengthen human capital by investing in employee development and offering supportive benefits such as training programmes, childcare support, or wellness initiatives. Several key factors influence how human capital develops:
| Determinant | How it shapes human capital |
|---|
| Formal education | Builds foundational knowledge, analytical ability, and credentials that signal competence to employers |
| Vocational and on-the-job training | Develops practical, role-specific skills that directly improve productivity and earning potential |
| Health and nutrition | Ensures a healthier workforce that is more productive, dependable, and less prone to absenteeism |
| Work experience | Enhances expertise, judgement, and practical knowledge that cannot be fully gained through formal education alone |
| Technology access | Improves efficiency and adaptability by enabling familiarity with digital tools and modern work systems |
| Socio-economic environment | Influences access to education, career opportunities, and long-term professional growth based on background and resources |
Theories of human capital
The concept of human capital has evolved over time through the work of leading economists. In the 18th century, Adam Smith introduced the idea in An Inquiry into the Nature and Causes of the Wealth of Nations, highlighting that the productive abilities of individuals are as valuable as physical tools and resources.
In the 1960s, Theodore Schultz expanded this idea by analysing the economic value of human capabilities. He compared human capital to physical assets such as machinery and factories, arguing that investments in education and training should be treated similarly to investments in physical capital, as they enhance productivity and expand opportunities.
Gary Becker further developed the theory by distinguishing between general human capital and specific human capital. General human capital refers to skills that are transferable across employers, such as literacy and numeracy, while specific human capital relates to skills that are valuable only within a particular organisation. Becker emphasised that the expected return on education plays a key role in shaping individuals’ decisions regarding learning and skill development.
Although the terms “human capital” and “human resources” have faced criticism for treating employees as assets, the framework remains useful for understanding how education, skills, and productivity contribute to economic growth.
Human capital and economic growth
There is a strong link between human capital and overall economic growth. Businesses that invest in their workforce tend to achieve higher productivity, increased revenue, and improved profitability. At a broader level, countries that prioritise education and healthcare often experience stronger GDP growth and enhanced global competitiveness. Key ways in which human capital supports economic growth include:
- Labour productivity: Skilled employees generate higher output per hour, helping reduce costs and improve competitiveness.
- Innovation and R&D: A strong human capital base supports research and development, leading to technological advancements and the creation of new industries.
- Entrepreneurship: Individuals with higher education and skills are more likely to start businesses, contributing to job creation and economic dynamism.
- Technology adoption: Workers with advanced skills can quickly adapt to new technologies, enabling faster productivity improvements.
- Human capital migration: Skilled individuals often move to regions with better opportunities. Countries that lose talent may face brain drain, while those that attract talent gain a competitive edge.
Depreciation note: Similar to physical assets, human capital can depreciate over time. Skills may become outdated if not regularly updated, which can be reflected in reduced earning potential or productivity. Continuous learning and reskilling are essential to maintain its value.
Investing in human capital: the employer’s perspective
From an organisational standpoint, human capital is typically managed by the HR function, which handles workforce planning, recruitment, training, and performance management. Since human capital improves through education and skill development, investing in employees can enhance work quality and lead to stronger business performance.
Companies that invest in employee development and achieve better results can track the return on investment in human capital over time. Key areas where organisations invest include:
- Formal training programmes: Structured learning initiatives such as workshops, certifications, and leadership development programmes that enhance job-specific skills.
- Tuition reimbursement: Financial support for employees pursuing higher education aligned with business requirements.
- Mentoring and coaching: Knowledge-sharing through peer mentoring, reverse mentoring, and executive coaching to build organisational capability.
- Digital upskilling: Training employees in data literacy, digital tools, and AI capabilities to keep pace with evolving workplace demands.
- Health and wellness benefits: Providing healthcare, mental health support, and wellness programmes to maintain workforce productivity.
- Career development paths: Creating opportunities for internal growth, promotions, and succession planning to retain talent and reduce attrition.

History of human capital
The concept of human capital has developed over several centuries, evolving from early economic observations into a formal framework that influences both policy and business strategy today. Key milestones include:
| Period | Development |
|---|
| 18th century | Adam Smith’s The Wealth of Nations (1776) recognised that the skills and capabilities of workers are as important as physical assets in creating national wealth |
| 19th century | Economists began distinguishing between labour as a commodity and the productive abilities embedded in individuals |
| 1961 | Theodore Schultz’s paper Investment in Human Capital formalised the concept and argued that education and training should be treated as investments rather than expenses |
| 1964 | Gary Becker’s book Human Capital expanded the theory by introducing general and specific human capital and linking education to lifetime earnings |
| 1970s to 1990s | Human capital theory influenced global education policies, with countries measuring educational attainment as an indicator of national capability |
| 2000s to present | The concept has broadened to include soft skills such as emotional intelligence, creativity, resilience, and digital capabilities, with a strong focus on lifelong learning and workforce reskilling |
Examples of human capital
Human capital exists across all industries, roles, and levels of the economy. It can be observed at the individual, organisational, and national levels. Some practical examples include:
| Level | Example | Type of human capital |
|---|
| Individual | A software engineer skilled in machine learning and cloud computing | Technical expertise and specialised knowledge |
| Individual | A doctor with over 15 years of surgical experience | Clinical expertise, practical knowledge, and decision-making ability |
| Individual | A multilingual sales professional with strong relationship-building skills | Soft skills, language proficiency, and interpersonal ability |
| Organisation | A data analytics team that improves customer targeting by 30% | Analytical capabilities and domain expertise |
| Organisation | A customer service team trained in empathy and problem-solving | Soft skills and emotional intelligence |
| National | South Korea’s focus on STEM education supporting semiconductor and tech exports | Skilled workforce and national human capital strength |
| National | India’s large pool of IT professionals serving global companies | Technical skills, English proficiency, and cost advantage |
Relationship between human capital and the economy
Human capital plays a direct role in shaping economic performance across multiple dimensions. Its impact can be understood as follows:
| Dimension | Role and impact on the economy | Key drivers |
|---|
| Productivity | Skilled workers produce more output in less time and use resources more efficiently | Education, workplace training, healthcare |
| Innovation | A strong talent base supports research and development, leading to new technologies and products | Higher education, research funding |
| GDP growth | Improved skills lead to higher incomes, which in turn boost spending and tax revenues | Efficient labour markets and wage growth |
| Global competition | Countries with stronger human capital perform better in knowledge-driven industries | Specialised skills and digital capabilities |
| Sustainability | Skilled talent is essential for long-term economic and environmental sustainability | Environmental awareness and green technology skills |
What is human capital risk?
Human capital risk refers to the gap between the skills a company needs and the skills available within its workforce. It highlights potential vulnerabilities that can affect business continuity and performance. Common types include:
- Key person dependency: Over-reliance on a single individual whose absence could significantly disrupt operations, especially in specialised roles or smaller businesses.
- Skills obsolescence: Rapid technological changes can make existing skills outdated, particularly if organisations do not invest in continuous learning.
- Talent retention: High employee turnover increases hiring costs, disrupts workflows, and leads to loss of institutional knowledge.
- Succession gaps: Lack of planning for leadership or critical roles creates risk when key personnel leave or retire.
- Disengagement: Employees who are not engaged tend to be less productive, more absent, and more likely to leave, impacting overall performance.
Difference between human capital and physical capital
Understanding the distinction between human and physical capital is essential for analysing how value is created in modern economies:
| Feature | Human Capital | Physical Capital |
|---|
| Nature | Intangible and embedded in individuals | Tangible assets such as machinery, buildings, and equipment |
| Ownership | Cannot be owned; organisations access it through employment | Fully owned by the organisation |
| Depreciation mechanism | Skills may become outdated without continuous learning; health may decline over time | Wears out through use or becomes outdated due to technological changes |
| Appreciation | Can grow through education, experience, and training | Typically depreciates and requires reinvestment |
| Transferability | Skills can be applied across roles and organisations | Assets are usually fixed and location-specific |
| Balance sheet treatment | Not recorded on the balance sheet | Recorded as fixed assets and depreciated over time |
Challenges in measuring human capital
Measuring human capital is inherently complex because, unlike financial elements such as debt or equity, it does not have a standard unit of measurement. As a result, organisations face several practical challenges when attempting to evaluate it:
- Intangibility: Qualities such as creativity, leadership, and tacit knowledge cannot be directly measured. Common proxies like years of education or training hours often fail to capture true capability.
- Context dependency: The value of human capital differs across roles, industries, and organisations, making it difficult to apply a uniform metric.
- Attribution difficulty: Separating the impact of human capital investments from other business factors is challenging when assessing outcomes.
- Over reliance on proxies: Many organisations depend on indicators such as graduation rates, training hours, or employee satisfaction scores, which may not accurately reflect actual performance or skill levels.
- Short term focus: Pressure to reduce costs can lead to cuts in training and development, which may improve short term financial results but weaken human capital over time.
Conclusion
Human capital represents the economic value of an individual’s skills, knowledge, and abilities. Businesses can strengthen their human capital by recruiting skilled talent and investing in continuous learning and development for their workforce. At a broader level, countries that prioritise education, healthcare, and workforce mobility tend to build more resilient and competitive economies.
