Human Life Value Calculator United States
This human life value calculator sizes life insurance from the present value of your future earnings, grown and discounted over the years you want to protect.

What it does
The Human Life Value Calculator estimates the present value of your future earnings for dependents, the income-replacement basis for sizing life insurance.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Human life value = sum of base x (1+growth)^(t-1) / (1+discount)^t over each year t
How it works
It grows your replaced income each year and discounts it back to today, summing the present values across the years you want to protect.
Where it is used
- Sizing life insurance coverage
- Valuing lost future income
- Planning family financial protection
Worked example
Replacing 70% of an $80,000.00 income for 30 years at a 5% discount rate gives a human life value of … and a recommended coverage of ….
What the human life value calculator does
The human life value calculator estimates what your future earnings are worth to the people who depend on you: how much money it would take today to replace what you would have earned over the rest of your working life if your income stopped. It turns that stream of future pay into one present-day figure, a reasonable starting point for how much life insurance to carry.
Human life value is one of two common ways to size life insurance. It treats your earning power as the asset insurance protects. The other, needs-based analysis, adds up specific obligations. Comparing the two often helps settle the final amount.
How the calculation works
The calculator starts from the share of your income that supports your dependents: your annual income times the replacement percentage you choose. Each year that amount grows by an income growth rate for raises and inflation, and each year’s figure is discounted back to the present at a discount rate, because future income is worth less than income today.
For each year it takes the replaced income grown to that year, divides it by that year’s discount factor, and adds the result to a running total. The total over all the years you want to protect is your human life value. Subtracting the life insurance you already hold gives the additional coverage to consider.
Why the replacement percentage matters
Part of what you earn is spent on yourself, so replacing 100% of income usually overstates the need. The relevant figure is the income your dependents rely on. One earner supporting several dependents might replace a high share, while a dual-income household with few dependents might replace less. This choice has a large effect on the result, so base it on your family’s actual spending.
The growth rate and the discount rate
The income growth rate reflects how your earnings are likely to rise through promotions, raises and inflation; a higher rate increases human life value. The discount rate reflects what money could earn if invested today and works the other way; a higher rate lowers the present value. Because they pull against each other, the gap between them matters more than either one, and small changes in that gap can move the result a lot. Try a range of assumptions.
What you need to enter
- Your annual income.
- The number of years of income to protect, often the years until retirement.
- The share of income that supports your dependents.
- An income growth rate and a discount rate.
- Any life insurance you already hold.
If you are unsure, start with conservative assumptions and see how sensitive the result is.
Reading your result
The output shows your total human life value, the recommended coverage after existing insurance, the income replaced in the first year, and the total nominal income replaced over the period. A needs-based estimate that adds up debts, the mortgage and education costs answers a slightly different question and can give a different figure; the final decision usually falls somewhere between the two.
When to revisit the estimate
Human life value changes as your income grows, the years to retirement shrink and your family changes. A raise, a new child, a home purchase or a change in how much your dependents rely on you are all reasons to recalculate, as is a check every few years.
Using the figure
Some households buy one term life policy sized to the full figure, with a term matching the years of income to protect. Others layer several policies of different lengths, sometimes called laddering, so coverage is highest while children are young and steps down as obligations end. The year-by-year present values show how the need falls over time, which helps choose between one large policy and several staggered ones.
Human life value does not include one-off costs such as final expenses or a specific college fund. If those matter, add them separately on top of the human life value.
