Determining How Much Life Insurance a Family Needs
A policy’s face amount is a decision about arithmetic and judgment, and a producer who cannot show the arithmetic is guessing. Two methods answer the question. Human life value prices what a person’s future earnings are worth. The needs approach prices what a particular family would have to pay for and what it would have left to pay with. Both methods are worked below on invented people, and the result shows how far the answer moves when an assumption moves. The figures are examples chosen for plausible arithmetic. They are not statutory figures and they are not a rate anyone is promised.
Human Life Value
Human life value is the present value of the earnings a person would have produced for dependents if he or she had lived. It starts with a calculation that is easy to get wrong in one direction: the family never saw all of the paycheck. Taxes came out first, and the earner spent a share on his or her own food, clothing, transportation and pleasures. Only what remained went to the family. That remainder is what the policy replaces.
Dana Whitaker, age 40, earns $84,000 and expects to work until 65, which is 25 more years. After taxes and her own consumption, 65% of her pay supports the household, so the first year’s contribution is $84,000 times 0.65, or $54,600. She expects raises of 3% a year, and a lump sum today can be invested at 5%. Each year’s contribution is discounted back to today:
Present value = the sum, for each year t from 1 to 25, of $54,600 × 1.03^(t-1) ÷ 1.05^t
That sum is $1,042,045. Her human life value is about $1.04 million.
Three points follow from the method.
- The result is an economic worth, not a purchase order. A family rarely needs $1.04 million at death, because a surviving spouse may earn income, savings and group coverage may already exist, and some of the household’s costs end with the insured.
- Every input is a forecast. Change the discount rate from 5% to 4% and the answer rises sharply, because more years of money are worth more today.
- It does not look at the family at all. Dana’s value is the same whether she has four children or none. For that reason human life value is used where the question is the value of a life, as when a court sets damages in a wrongful death case, and it serves a producer as an upper reference point rather than as the recommendation.
The Needs Approach
The needs approach starts from the family and works outward. The producer gathers four kinds of information.
| Information | What it covers | Why it matters |
|---|---|---|
| People | Ages of the insured, spouse and children, health, and who depends on whom | Sets the length of each need |
| Income | Earnings of each adult, benefits, and what survivors would receive from Social Security according to the family’s own earnings statement | Shows what continues after a death |
| Assets and liabilities | Savings, investments, retirement accounts, home equity, mortgage and other debts | Shows what can be used and what must be repaid |
| Existing insurance and goals | Group and individual coverage, and what the family wants paid for, such as a home free of debt or college | Sets the target and subtracts what is already in place |
Each number has a source, and the producer asks for the document rather than an estimate. The mortgage balance comes from the latest statement, not from memory of the original loan. Group coverage comes from the employer’s benefits summary, which also shows whether the coverage can be taken along or converted if the job ends. Retirement accounts deserve care. A family that counts a 401(k) as money available at death overlooks that withdrawals are taxed and that the spouse may need the account for her own retirement, so the example below leaves retirement accounts out. The same discipline applies to goals. A family that says it wants the children’s college paid has to say whether that means a state university or a private one, because the difference is a hundred thousand dollars of face amount.
The method then sorts what the family needs into two groups. Lump-sum needs are paid once, at or soon after death. Income needs are monthly or yearly costs that run for a period. The two are added together, and the family’s existing resources are subtracted. The remainder is the additional insurance the family needs.
A Michigan Family Worked Through
Marcus Delgado, 36, and Priya Delgado, 34, live in Ann Arbor with Mateo, 6, and Lucia, 3. Marcus earns $78,000 as a project engineer. Priya works part time and takes home $26,000 a year. They have asked what happens to the household if Marcus dies. Money earns 4% after taxes in the calculation. The producer states each assumption aloud so the Delgados can change it.
Lump-sum needs
| Item | Amount |
|---|---|
| Funeral and burial | $14,000 |
| Last illness costs and estate settlement | $8,000 |
| Car loan | $16,500 |
| Credit card balances | $7,200 |
| Mortgage payoff | $214,000 |
| Emergency fund, six months of the survivors’ budget ($4,500 × 6) | $27,000 |
| Subtotal before education | $286,700 |
Whether to pay off the mortgage and the cards is the family’s choice, not a rule. The producer shows the effect of each choice. A Michigan fact belongs in this conversation. Life insurance proceeds payable to a surviving spouse or children are exempt from execution or liability to any creditor of the insured (MCL 500.2207(1)). The exemption does not apply to a transfer made with intent to defraud creditors (MCL 500.2207(1)). A creditor of Marcus therefore cannot take the proceeds from Priya, though the mortgage lender, which holds a lien on the house, can still foreclose if the payments stop. The exemption speaks to creditors of the insured, so it doesn’t reach a debt Priya owes in her own right. The worksheet lists the debts so the family decides which to retire. It does not list them because the law forces it.
Education. A four-year program costs $26,000 a year today, and costs rise 5% a year. Mateo starts in 12 years and Lucia in 15. The Delgados want both fully funded. Each year’s bill is inflated to its own date and discounted back at 4%.
| Child | Years from now of the four payments | Present value |
|---|---|---|
| Mateo | 12, 13, 14, 15 | $118,349 |
| Lucia | 15, 16, 17, 18 | $121,796 |
| Total | $240,144 |
The first payment for Mateo shows the method. In year 12 the cost is $26,000 grown at 5% a year for 12 years, or $46,692. Discounted at 4% over 12 years it is worth $29,164 today.
Income needs. Priya wants to keep working while the children are young, and she would need paid child care, $7,200 a year, to do it. The survivors’ budget is $4,500 a month, or $54,000 a year, with no mortgage payment because the house is paid off. With child care the total is $61,200. Against that:
- Priya’s take-home pay is $26,000.
- Survivor benefits, from a Social Security earnings statement estimate in this example, come to $22,800 a year while the children are young. Survivor benefits step down as each child grows up, so a level figure for 15 years is a simplification, and a real worksheet follows the schedule on the family’s own statement.
- The gap is $61,200 minus $26,000 minus $22,800, or $12,400 a year for the 15 years until Lucia turns 18.
There are two ways to fund a gap, and the choice changes the amount.
- Capital retention invests a sum and spends only the interest, so the principal is still there at the end. At 4% the sum is $12,400 ÷ 0.04, or $310,000.
- Capital liquidation spends interest and principal together so that the fund is empty at the end of the 15 years. The factor for 15 years at 4% is 11.1184, so the sum is $12,400 × 11.1184, or $137,868.
Retention leaves an estate and costs more than twice as much. Liquidation costs less and leaves nothing for Priya at the end. The Delgados choose liquidation. A fuller plan adds a third period for Priya’s own retirement. This example stops where the children are grown to keep the arithmetic readable.
Two checks on the income figure. The $12,400 gap is stated in level dollars, but the Delgados’ costs will rise. If the gap grows 3% a year and the fund earns 4%, each year’s amount is discounted separately, and the present value is $167,296, not $137,868. The producer shows both and lets the family decide how much inflation protection to buy. Priya’s own earnings will also rise, which is why the gap is a shaky number in either direction and why the numbers are reviewed after each life event.
The second check is the mortgage. The Delgados’ $214,000 loan carries 5.5% interest and has 27 years left, so the monthly principal and interest payment is $1,269.31. If the policy paid only the monthly payments, the lump sum needed would be the present value of 324 payments at the 4% return, which is $251,245. Paying the loan off costs $214,000, or $37,245 less. The present value uses 4% a year, compounded monthly. The comparison turns on one fact: when the loan rate is higher than the rate the policy proceeds can earn, paying off the loan is the cheaper way to meet the need. If the loan rate were below the return, the answer would reverse.
Putting it together
| Line | Amount |
|---|---|
| Lump-sum needs | $286,700 |
| Education | $240,144 |
| Income needs, liquidation | $137,868 |
| Total needs | $664,712 |
| Less group life through Marcus’s employer, two times salary | $156,000 |
| Less individual term already owned | $100,000 |
| Less savings and brokerage accounts available (retirement accounts left out) | $19,000 |
| Total existing resources | $275,000 |
| Additional insurance needed | $389,712 |
A producer would round to $400,000 and note one fact about the resources. The group coverage ends when Marcus leaves the job, so the real need could rise by $156,000 at the worst time. The recommendation therefore uses individual term sized for the long period, with the group coverage treated as a bonus.
How Much the Answer Moves
The assumptions are the weak point, and the Delgados should see how the result changes when they change.
| Assumed return after taxes | Education | Income needs | Additional insurance needed |
|---|---|---|---|
| 3% | $277,732 | $148,030 | $437,462 |
| 4% | $240,144 | $137,868 | $389,712 |
| 5% | $208,000 | $128,708 | $348,408 |
A one-point change in the assumed return moves the answer by about $40,000 to $50,000. A rule of thumb that multiplies income by ten would have recommended $780,000 of total coverage on Marcus’s $78,000 salary. The Delgados already own $256,000 of group and individual coverage, so the rule would add $524,000, about $134,000 more than the $389,712 their own facts support. It would have recommended the same $780,000 to a couple with no children and no mortgage. The needs approach is longer, but it ties every dollar to something a family can recognize.
The Second Earner
Insuring only the main earner is a common mistake. If Priya died, Marcus would lose her $26,000 and would also have to buy the work she does at home, child care and household help, in the example $14,400 a year for 15 years. At 4% that service alone has a present value of $14,400 × 11.1184, or $160,105. A household that insures one parent and not the other is carrying a risk it never priced.
Turning the Need into a Recommendation
The producer presents the result as a range with the assumption that drives it, never as a single figure. The Delgados see $349,000 to $437,000, the middle case of $390,000, and the two inputs that move it most, the assumed return and the choice to pay off the mortgage.
The number is a target, and the choice of policy follows from how long each need lasts.
- A need that ends at a known date, like education and the income gap above, fits term insurance that runs to that date. The Delgados’ income gap ends in 15 years and the last tuition payment is 18 years away, so a 20-year term policy covers both.
- A need that does not end, such as final expenses or an estate for a surviving spouse, fits permanent insurance if the family can afford the higher premium.
- A need that declines, such as a mortgage balance, can be matched with decreasing term, though a level amount is easier to keep track of.
How the Need Changes Over Time
The Delgados’ need is not constant, and the calculation shows where it falls. Using the same assumptions, with the unsecured debts assumed paid down, the need at death on four dates is:
| If Marcus dies in year | Mortgage balance | Education still to fund | Income gap still to fund | Final expenses and emergency fund | Total need |
|---|---|---|---|---|---|
| 0 | $214,000 | $240,144 | $137,868 | $49,000 | $641,012 |
| 10 | $167,985 | $355,472 | $55,203 | $49,000 | $627,660 |
| 15 | $133,588 | $165,295 | $0 | $49,000 | $347,882 |
| 20 | $88,330 | $0 | $0 | $49,000 | $137,330 |
Education stays large for ten years because the tuition bills grow faster than the fund earns, while the income gap shrinks every year it is paid. The total barely moves for ten years and then falls by almost half by year 15. A 20-year term policy sized for the early years therefore leaves the family covered through the years of greatest need, and part of it is surplus after that. The Delgados’ existing resources of $275,000 would also change, because the group coverage ends if Marcus changes jobs, and their savings should grow. Many producers meet a need like this with a base policy for the full period and a smaller second policy for the first ten or fifteen years, but the figures above, not a formula, tell the producer where the steps belong.
The producer reviews the numbers again after each life event: a birth, a new mortgage, a divorce, a promotion, or a child’s graduation.
Errors a Worksheet Should Catch
A needs analysis fails quietly. The arithmetic can be right and the answer wrong, because of a few recurring errors.
- Counting the same dollar twice. If the survivors’ budget already includes $5,000 a year for children’s activities and the education line also funds school costs, the overlap inflates the answer. Each cost belongs on one line.
- Mixing before-tax and after-tax dollars. The Delgados’ income lines are take-home pay, so the return assumption is also after taxes. Setting a before-tax salary against an after-tax budget understates the gap.
- Treating group coverage as permanent. It ends with the job, and a conversion privilege, where one exists, is priced at the insured’s age at the time and is usually permanent insurance at a higher premium.
- Ignoring the survivor’s own future. The example stopped where the children were grown. A surviving parent of 49 with no retirement savings still has a need that begins there.
- Using one scenario. The family needs the death-in-year-one case and the death-in-year-ten case, as the table above shows, because the answer is different in each.
- Forgetting the disability case. The same worksheet, run for a disabling illness instead of death, shows that the family needs income replacement and keeps paying the premiums. Life insurance does not answer that case, and the producer should say so.
Presenting the Result
A producer who walks in with a number has already lost the conversation. The order that works is to confirm the goals, show each need as a line the family recognizes, subtract what they have, and only then name the gap. When a family says it cannot afford the amount, the answer is to change the plan on the page, not to shrink the number in silence. They can shorten the education goal, choose liquidation over retention, or carry the mortgage rather than pay it off. Each choice has a computed effect. The producer records what the family decided and why, because a file that shows the analysis protects the family and the producer if the death comes before the coverage is increased.
Lesson summary
- Human life value is the present value of the earnings the insured would have contributed to dependents, after taxes and the insured’s own consumption. It is an upper reference point, and it is used in wrongful death valuation.
- The needs approach gathers information on people, income, assets and liabilities, and existing insurance and goals, then adds lump-sum needs and income needs and subtracts existing resources.
- Lump-sum needs include final expenses, debts, a mortgage payoff if the family chooses it, an emergency fund and education. Education is inflated to the year of each bill and discounted back.
- Income needs are the gap between the survivors’ budget and their income plus survivor benefits. Capital retention spends only interest, and capital liquidation spends principal too, so it costs less.
- In the worked case, total needs were $664,712 and existing resources $275,000, so the additional insurance needed was $389,712. The result moves about $40,000 to $50,000 for each point of change in the assumed return.
- Michigan exempts life insurance proceeds payable to a spouse or children from the insured’s creditors (MCL 500.2207(1)), so paying off unsecured debts from proceeds is the family’s decision.
- The coverage on a second earner should include the cost of replacing the work done at home.
- A need with an end date fits term insurance to that date, and a need with no end date fits permanent insurance.
