Human Life Value Calculator

What human life value means

Human life value is how much money it would take today to replace everything a person would have earned for the rest of their working life if their earnings suddenly stopped. It is a long-established anchor for deciding how large a life-insurance policy should be, because it ties the amount of cover to the income a household depends on.

Adding up every year of salary until retirement gives a large headline number, but that total overstates the value, because income arriving decades from now is worth far less today than income arriving next year. The calculator discounts the future earnings back to the present and expresses a lifetime of expected pay as one value in today's money.

How the calculator works

You enter your annual income, the number of years until you retire, and a discount rate, the annual percentage used to translate future money into present money.

The calculator treats your remaining earnings as an annuity, a fixed payment received once a year for a set number of years, and discounts it to a present value using the standard formula:

HLV = Income × (1 − (1 + r)^−n) ÷ r

Here r is the discount rate expressed as a decimal and n is the number of years of earnings you have left. When the discount rate is zero, the formula reduces to income multiplied by the number of years. The calculation runs in your browser, so you can adjust the inputs and watch the value respond.

Why discounting matters

A dollar, euro or pound you would earn twenty-five years from now is worth less than a full unit today, because money you had now could be invested and grow. Discounting asks what smaller amount today would grow into that future earning by the time you received it.

The effect is large over a working lifetime. Someone earning 60,000 a year with twenty-five years left before retirement would earn 1,500,000 in total. Discounted at 4% a year, the human life value is roughly 937,000. The calculator shows the gap of over half a million as a separate figure and as a slice of the donut chart.

Choosing a discount rate

The discount rate changes the result more than any other assumption. Many planners use a conservative long-term investment return, the sort of rate you could reasonably expect from safe assets over decades; 3% to 5% is common. A higher rate makes future income look less valuable and lowers the human life value, and a lower rate does the opposite. Try a range of rates: if the value is stable across sensible rates, you can rely on it, and if it swings widely, the assumption is doing much of the work.

Common uses

• Sizing life insurance. The human life value shows how much cover would replace the income your family relies on, so a policy at or near that level keeps their standard of living intact.
• Comparing life stages. A younger earner with decades of income ahead has a far higher human life value than someone close to retirement, so insurance needs fall over time as fewer earning years remain.
• Testing assumptions. Changing the income, the years and the discount rate shows which assumption drives the result.

Reading the results

The human life value is the present value of your future earnings and the natural target for income-replacement cover. The total future income is the undiscounted sum of all those salaries, a useful check that overstates the economic value. The effect of discounting is the difference between the two. The donut chart splits the raw future income into the part that remains as present value and the part removed by discounting.

What the number does not include

A complete insurance decision usually goes further than lost earnings. A full needs analysis adds outstanding debts such as a mortgage, final expenses, and future goals like a child's education, then subtracts assets you already have: savings, investments and any existing cover. Human life value sizes the income-replacement piece, often the largest, so adjust it for your family's debts, goals and resources before settling on a policy amount.
