Calculation & Conversion / Calculators
Life Insurance Needs Calculator
This calculator sizes a life insurance policy from the needs side instead of guessing at a multiple of salary. It replaces the income your household would lose, clears your debts, funds your children's education and covers final expenses, then subtracts the cover and savings you already have. The difference is your coverage gap, which it prices as monthly level-term premiums at 10, 15, 20 and 30 years.

Your household
Enter 0 if yours is the only income in the household.
Until your youngest child is independent, or your mortgage is paid off. Your years left at work is a common default.
What your family would need
Mortgage balance, car loans, student loans, credit cards.
Total for all children. A four-year in-state public degree runs about $100,000 per child today.
Funeral and estate settlement. The median burial is $8,300; with a vault, $9,995; $12,000–$15,000 once the plot and headstone are included.
What they already have
Include free group cover from your employer.
Cash, brokerage and retirement accounts a survivor could actually draw on.
Only terms that end by age 80 are listed — longer ones are rarely issued.
Coverage to buy
$1,150,000
A coverage gap of $1,109,018, rounded up to the next $50,000 increment — carriers issue policies in fixed bands. That is 13.5× your annual income.
It assumes your household keeps $40,000 a year of income it no longer has, over 30 years, plus every one-off obligation below.
How the number is built
Every line is a whole dollar figure, and the total is their sum — so you can add it up by hand and get the same answer.
What your family needs
- Income replacement (present value)
- $784,018
- Debts paid off
- $305,000
- Education fund
- $120,000
- Final expenses
- $15,000
- Transition buffer (6 months)
- $20,000
- Total need
- $1,244,018
What you already have
- Existing life insurance
- $50,000
- Savings and investments
- $85,000
- Total available
- $135,000
Total need minus what you already have. This is the only number in the report that changes when you edit your existing cover or savings.
Why income replacement is not simply income × years
A lump sum does not have to equal the raw total of future income, because the money keeps working while it is drawn down. Assuming a 3% real return (investment return after inflation):
| Measure | Amount | Multiple of income |
|---|---|---|
| Income × years (no discounting) | $1,200,000 | 14.1× |
| Present value at 3% | $784,018 | 9.2× |
| Rule of thumb (10–15× income) | $850,000 – $1,275,000 | the conventional band |
| Total coverage recommended here | $1,150,000 | 13.5× |
The recommendation sits inside the 10–15× band. Landing outside it is not an error — the band cannot see a mortgage balance or a college fund, which is exactly why this calculator exists.
What that cover costs by term length
The same $1,150,000 of level term, priced from published average rate tables for a non-smoker in the preferred health class at age 35. Prices are premiums, not quotes.
| Term | Per month | Per year | Total paid over the term | Covers the 30-year need |
|---|---|---|---|---|
| 10 years | $51.74 | $621 | $6,209 | No — expires 20 years early |
| 15 years | $61.91 | $743 | $11,144 | No — expires 15 years early |
| 20 years Shown above | $74.08 | $889 | $17,779 | No — expires 10 years early |
| 30 years | $128.12 | $1,537 | $46,123 | Yes |
Longer terms cost more for two independent reasons: you are covered for more years, and those extra years happen to be the ones where mortality risk climbs fastest. Compare the right-hand columns — a 30-year term can cost more in total than a 20-year term costs in full, for cover you may not need past the mortgage.
Before you buy
Check this
A 20-year term is shorter than the 30-year need
You asked for a 20-year term, but the model replaces income for 30 years. The policy would expire while the need is still running, and renewing at that point means re-qualifying at an older age at a much higher rate — the premium roughly doubles every decade. Either lengthen the term, or accept that the later years are funded some other way.
Context
Employer group coverage is not permanent
Free group life from an employer is typically 1-2 times salary and ends when the job does. It is legitimate to count it against today's need — that is what this calculator does — but do not let the total you own rest on it.
Context
Things this estimate deliberately does not count
Social Security survivor benefits (a surviving spouse caring for a child under 16 and each dependent child may qualify — worth checking your statement before buying), pension or annuity income that continues to a survivor, the cost of settling an estate beyond the final-expenses figure, and inflation on the education goal. Every one of those reduces the amount you need, which makes this estimate conservative by construction.
Context
This is a needs analysis, not a quote
The coverage figure comes from your own inputs and the formula shown above. The premiums come from published average rate tables for a non-smoker in the preferred health class — an actual offer depends on your medical history, family history, occupation and the carrier, and identical applicants are routinely quoted 100% apart. Shop at least three carriers, and confirm the premium is level for the full term rather than increasing yearly.
How we estimate — and what this is not
coverage = PV(annual income − spouse income for 30 years at 3%) + debts + education + final expenses + 6 months of income − existing cover − savings
- Annual income gap
- $40,000 / yr
- Real return assumed
- 3%
- Rate per $1,000 of cover, 20-year term
- $0.0644 / mo
- Premium at that rate
- $74.08 / mo
This is a needs analysis, not financial advice. The coverage figure comes from your inputs and the formula above; the premiums come from published average rate tables (Policygenius Life Insurance Price Index, October 2025; MarketWatch, July 2025) for a non-smoker in the preferred health class. A real offer depends on your medical history, family history, occupation and the carrier — identical applicants are routinely quoted 100% apart. Social Security survivor benefits, continuing pension income and estate taxes are not modelled here, all of which reduce the amount you need. Confirm the premium is level for the full term rather than increasing annually, and get at least three quotes before you sign.

How to use
- 1
Enter your household income
Add your annual income, your age, your sex — rate tables are priced by sex and women typically pay 15% to 25% less — and whether you use tobacco. Then add your spouse's income if there is one: the calculator replaces the shortfall, not your entire salary.
- 2
Set how many years your family would need the income
Use the years until your youngest child is financially independent, or until the mortgage is paid off, whichever comes later. Your remaining years at work is a common default.
- 3
Add the one-off obligations
Outstanding debts (mortgage, car loans, student loans, cards), what you intend to contribute toward each child's education — a four-year in-state public degree runs about $100,000 per child — and final expenses, where the median funeral with burial is $8,300 and roughly $15,000 once the plot and headstone are added.
- 4
Offset what you already own
Enter your existing life insurance, including free group cover from your employer, plus the cash, brokerage and retirement savings a survivor could actually draw on. Both reduce the amount you still need to buy.
- 5
Compare term lengths, then read the notes
The premium table prices the same cover at 10, 15, 20 and 30 years and flags whether each term outlives the need. Then read the caveats — Social Security survivor benefits, unpaid work and employer cover are the three things that most often move the answer after the arithmetic is done.
Key facts
- FormulaCoverage = present value of the annual income gap over the support years + outstanding debts + education fund + final expenses + a 6-month transition buffer − existing life insurance − liquid savings. The conventional shortcut is 10 to 15 times annual income; the detailed figure is shown against that band so the two can be compared.Source:Needs-analysis (DIME) method as used in financial planning; 10-15x income rule of thumb per published insurance guides
- Benchmark costA healthy non-smoking 30-year-old pays about $23.10 (female) to $29.56 (male) a month for $500,000 of 20-year level term, rising to $78.94-$103.55 at age 50 and $190.13-$264.84 at 60.

How this calculator works
Coverage is sized from the needs side rather than as a multiple of salary. The model takes the annual income the household would lose across the years it needs support, discounts that stream to a present value, and adds outstanding debts, an education fund, final expenses and a transition buffer. Existing cover and liquid savings are subtracted, and the remainder is the coverage gap, which is then priced as level term at ten, fifteen, twenty and thirty years.
The discount rate you choose drives the result more than any other input, because it does two jobs at once: it converts a future income stream into today's money, and it stands in for the return the payout could earn before it is spent. No tax is applied to the proceeds, and no allowance is made for the insured living longer or shorter than assumed. Premium figures are indicative rates for a healthy non-smoking applicant and are not an offer of insurance.
Disclaimer
This is an educational calculator, not financial advice. The result is an arithmetic projection of the figures you enter: it does not know your full circumstances, the terms of a specific offer, or the tax and regulatory rules that apply where you live. Confirm any figure against the terms of the product itself, or with a licensed professional, before acting on it.

Frequently asked questions
How much life insurance do I need?
The conventional answer is 10 to 15 times your annual income, and that band is a fair starting point — but it cannot see the two things that usually dominate the real number: your mortgage balance and what you intend to contribute to your children's education. A needs analysis works from the other direction. Add the income your household would actually lose (the shortfall between your income and your spouse's, for as many years as your family would need it, discounted to a present value), your outstanding debts, an education fund per child, final expenses and a six-month transition buffer. Then subtract the cover and liquid savings you already hold. For a 35-year-old earning $85,000 with a $305,000 mortgage, two children and $135,000 of existing cover and savings, that lands near $1,050,000 — roughly 12 times income. The gap between the two methods is the point: the income multiple is a floor, not an answer.
Term or whole life — which should I buy?
For almost everyone, level term. It buys the largest death benefit for the lowest premium, and the need for life insurance is almost always temporary: it tracks a mortgage, a career, and children who eventually support themselves. The price difference is not marginal — the same $500,000 that costs a healthy 30-year-old about $23 to $30 a month as a 20-year term runs roughly $408 to $472 a month as whole life, about 18 times more. Whole life bundles a permanent death benefit with a slowly growing cash value, which makes it worth considering in specific cases: an estate that will owe taxes, a business with a buy-sell agreement, a lifelong dependent, or a need that genuinely never expires. If the cash-value idea appeals, buy term and invest the difference — that comparison has been argued for decades, and term wins it for most households.
Do I need life insurance if I'm young and single?
Only if someone would be financially hurt by your death. With no dependents and no co-signed debt, the honest answer is usually no — or a small policy sized to final expenses and any loan a parent co-signed. Two reasons people still buy cover in their twenties. The first is insurability: your premium is locked at the age and health you apply at, and the price roughly doubles every decade, so locking in a low rate early is cheap if a mortgage and children are coming. The second is a known future obligation, such as a partner who depends on your income or a joint mortgage. Paying for thirty years of cover you do not need is not a bargain; buying a modest amount to preserve the option is a defensible call.
Should my spouse's income reduce how much cover I need?
Partly, and this calculator does subtract it — household spending broadly tracks household income, so a spouse who keeps earning covers a real share of the shortfall. The offset stops being reliable in three situations. If the mortgage or childcare genuinely requires both paycheques, losing one breaks the budget even though the other continues. If your spouse would have to cut hours to take over childcare, the income you subtracted is not really there. And the offset says nothing about unpaid work: replacing childcare commonly costs $20,000 to $40,000 a year, which is why a stay-at-home parent needs cover despite having no wage income. Treat the subtraction as a starting position, not a conclusion.
What does $500,000 of 20-year term life insurance actually cost?
Less than most people expect — more than 70% of Americans overestimate it, and younger buyers typically guess about three times the real price. In the Policygenius Life Insurance Price Index for October 2025, a healthy non-smoking 30-year-old pays about $23.10 a month as a woman and $29.56 as a man for $500,000 of 20-year level term. By 40 that is $35.58 and $43.52; by 50, $78.94 and $103.55; by 60, $190.13 and $264.84. Three factors move that number more than anything else: age, tobacco use (roughly two to three times the non-smoker rate) and term length (a 30-year term costs about 1.7 to 2 times the 20-year rate). Because shorter terms are cheaper, matching the term to the obligation usually saves more than shopping carriers over a few dollars.
