Human Capital
Human Capital in personal finance is the present value of all future earned income — salaries, professional fees, business income — that an individual expects to receive over their working life, and it is the largest asset on most people's personal balance sheets, forming the basis for calculating appropriate life and disability insurance coverage.
Economists define human capital as the productive capacity embodied in a person — their skills, knowledge, experience, and health. In the personal finance context, the practical application is more concrete: it is the NPV of future earnings, discounted at a rate reflecting the riskiness of those earnings. A salaried government employee with secure, predictable income has human capital akin to a bond — low volatility, long duration. A self-employed entrepreneur with variable income has human capital more akin to equity — higher expected return but significant variability.
For a 30-year-old earning Rs 15 lakh per annum with expected 7% annual pay growth, working until age 60, the NPV of future earnings (discounted at 8%) is approximately Rs 2.5 crore to Rs 3 crore. This figure dwarfs the financial assets most 30-year-olds have accumulated at that stage. Recognising this, financial planners argue that the most important 'investment' early in one's career is protecting human capital through term life and disability insurance.
Term life insurance coverage requirements are often calculated as a multiple of the human capital value. A thumb rule sometimes used is 10 to 15 times the current annual income, but a more precise approach is to calculate the income replacement needed by dependants if the breadwinner were to die today, discounted to a lump sum at an assumed investment return rate. The resulting number is typically much higher than most people are insured for — indicating a widespread underinsurance problem in India.
Disability insurance — covers loss of earning capacity due to illness or accident — is an even more underserved need in India because the probability of a career-disrupting disability during working years is statistically higher than the probability of premature death. Group disability covers offered through employers rarely account for the full human capital value.
As people age, human capital declines (fewer working years remaining) while financial capital should ideally grow. This lifecycle dynamic supports the conventional wisdom of shifting from equity to fixed income as retirement approaches — the bond-like nature of remaining human capital for older workers means they already have 'bond exposure' through their salary, so their portfolio should reflect that by holding more equity early and less later.
