Life Insurance Calculator – How Much Cover Would Your Family Actually Need?
Guessing a round number is how most people pick their life insurance cover — and how most end up with far too much or far too little. This calculator builds the figure from your real obligations instead, using the needs-based DIME method: the debts to clear, the income to replace, the mortgage to settle and the future costs to fund, minus what you already have. One thing it will never do is quote you a price: it works out an amount of cover, and what that cover costs is a separate question entirely.
Your obligations and what you already have
What the money would have to cover — the DIME list
Credit cards, car and student loans, personal loans — every balance your family would be left holding. The mortgage has its own field below.
Between 0 and 40. Ten years is a common starting point — often until the youngest child is grown.
Clearing it lets your family stay in the home on a much smaller income. If your mortgage is already inside the debts figure above, leave this at 0 so it is not counted twice.
Advanced options — education costs, final expenses, savings and existing cover
College funds and any other big planned costs you had promised to cover.
Funeral and end-of-life costs. Leave blank if you do not want to include them.
What you already have in place
Cover provided through an employer usually ends, or becomes expensive to keep, when you leave that job — read the FAQ before counting it at full value.
The advanced fields below are already included in the result with their default values — open Advanced options to change them.

Your recommended cover
Where the number comes from
What this means
Income replacement is the biggest single part of this need: $800,000 of the $1,200,000 total. That is normal — for most households the lost pay cheques matter far more than any single debt. The $1,050,000 is an amount of protection to aim at, not a bill: what it would cost depends on your age, health and the kind of policy, and no premium is estimated anywhere on this page.
Read this as the size of the safety net, not its price tag. Two people can need the same $1,050,000 of cover and be quoted completely different premiums, because pricing is personal — age, health, medical history, habits and how long the cover runs all feed into it. This calculator deliberately stops at the amount.
- DIME builds cover from debts, income times years, mortgage and education costs, minus savings and any cover already in place.
- The answer is an amount of protection, never a price or premium — a premium depends on age, health, habits, occupation and policy type.
- Re-run the number when life changes: a new mortgage, a child or a promotion rewrites at least one DIME letter.
See what the cover has to do
The top bar is the total need, built piece by piece from the DIME list. The bottom bar is what you already have — and the open stretch beside it is the gap a policy would actually have to fill. Change any figure above and the picture redraws itself.
| Years of income replaced | Income to replace | Recommended cover |
|---|---|---|
| 5 years | $400,000 | $650,000 |
| 10 years | $800,000 | $1,050,000 |
| 15 years | $1,200,000 | $1,450,000 |
| 20 years | $1,600,000 | $1,850,000 |
| 25 years | $2,000,000 | $2,250,000 |
Every extra year of income replacement adds a full year of pay to the need — which is why the years figure is the most powerful lever in the whole calculation, and the one worth thinking about hardest. Until the youngest child is independent is the horizon most households work to.

How it works
List what the money would have to do
Four jobs, one each for the letters of DIME: clear the Debts, replace the Income for as many years as your family would need it, settle the Mortgage so the home is safe, and fund the Education and future costs you had already planned.
Subtract what is already there
Savings and investments your family could draw on, plus any cover you already hold, come off the total. Skipping this step is the most common reason people end up over-insured on paper and under-protected in fact.
What is left is the gap to cover
The result is an amount of protection, sized to your obligations rather than to a slogan. If it comes out at zero, your existing position already covers the need this method calculates — the calculator says so plainly instead of inventing a gap.
The formula, and one worked example
Cover needed = (Debts + Income × Years + Mortgage + Education) − (Assets + Existing cover), never below zero
Worked example. Debts of $50,000; an income of $80,000 that the family would need replaced for 10 years, which is $800,000; a mortgage balance of $250,000; and $100,000 set aside in the plan for education. The total need is $50,000 + $800,000 + $250,000 + $100,000 = $1,200,000. Against that, the household already has $100,000 of savings and $50,000 of existing cover — $150,000 in place. So the recommended additional cover is $1,200,000 − $150,000 = $1,050,000. Note what the answer is and what it is not: it is an amount of protection. Nothing in the arithmetic says what that protection would cost per month, because that depends on the person, not the number.
Going deeper
The quickest method is the income multiple: ten to fifteen times your pay. It needs one number and ten seconds, and this page shows it as a comparison range — but it cannot see your mortgage, your debts, your savings or your existing cover, so it is a blunt instrument. At the other extreme sits the human life value approach, which totals the present value of everything you would earn over your whole working life, minus what you would have spent on yourself; it usually produces the largest figure of the three, and arguably measures your economic value rather than your family’s need. DIME sits between them and is the method used here, because it is anchored to obligations that actually exist: loans that must be repaid, a home that must be kept, children whose plans were already made. When the methods disagree, the needs figure is the one you can defend line by line.
People often arrive at a coverage figure and immediately ask what it costs a month. That price — the premium — is not a property of the amount. Insurers set it person by person, weighing age, current health, medical history, smoking and other habits, occupation, the type of policy and how long the cover runs. It is also why the kind of policy matters: cover that runs for a fixed term is a different product, with a very different price shape, from permanent cover designed to last for life and build value. Because none of those personal factors can be known from the figures on this page, any site that turns a coverage answer straight into a monthly price is guessing at your health on your behalf. Work out the amount honestly first; pricing is a separate step that needs your real details, and it is worth redoing the amount whenever life changes — a marriage, a child, a new mortgage, a new job.
Four households, four gaps
Every figure below was run through the calculator above, starting from its default household — $50,000 of debts, $80,000 of income to replace for 10 years, a $250,000 mortgage, $100,000 of education costs, $100,000 of savings and $50,000 of existing cover — and changing one thing at a time. No premium is estimated anywhere here, because a premium is not a property of the amount: it depends on age, health, habits, occupation and policy type, none of which this page knows. What changes below is only the amount of protection the DIME method points to.
| What changed | Total need | Already in place | Additional cover |
|---|---|---|---|
| Default household | $1,200,000 | $150,000 | $1,050,000 |
| Income needed for 20 years instead of 10 | $2,000,000 | $150,000 | $1,850,000 |
| Mortgage already paid off ($0) | $950,000 | $150,000 | $800,000 |
| Savings of $1,200,000 instead of $100,000 | $1,200,000 | $1,250,000 | $0 |
The years row is the one most people get wrong before they run it. Doubling the replacement period from 10 years to 20 does not double the answer: the total need rises from $1,200,000 to $2,000,000 and the additional cover from $1,050,000 to $1,850,000. Only the income-replacement part scales — $80,000 times 20 years is $1,600,000 instead of $800,000 — while debts, mortgage and education stay exactly where they were. That is why the years input deserves more thought than any other box on the page: it is usually the largest single part of the need (in the default, $800,000 of the $1,200,000 total), and it is also the most personal, because it encodes a judgement about how long the family would need the income — often until the youngest child is grown, which is why ten years is a common starting point rather than a rule.
The mortgage row settles a question the page is asked often: why is the mortgage counted separately from other debts, and what happens when there is no mortgage? The mortgage is its own letter in DIME because keeping the home is a distinct job from clearing other debts — a family can be debt-free on cards and loans and still lose the house if the mortgage is not covered. Remove it and the total need falls by exactly the mortgage balance, from $1,200,000 to $950,000, and the additional cover from $1,050,000 to $800,000. Nothing else moves. The same dollar-for-dollar logic applies to every letter: each $1 added to debts, education or the mortgage adds $1 to the need, and each $1 of savings or existing cover subtracts $1 — until the floor is reached.
That floor is the fourth row, and it is a feature, not a bug. With $1,200,000 of savings, the household already has $1,250,000 in place against a $1,200,000 need — $50,000 more than DIME calculates — and the calculator answers $0 rather than inventing a gap. A zero here does not mean “no insurance is ever needed”: it means this method, on these figures, finds the need already covered, and any cover bought on top would be bought for reasons outside this calculation — a larger legacy, business protection, or a different method’s answer. The calculator says so plainly instead of manufacturing a number, and that honesty is worth more than a flattering recommendation.
For comparison, the quick income-multiple method the page shows alongside DIME gives 10 to 15 times the $80,000 income, or $800,000 to $1,200,000. The DIME answer of $1,050,000 sits inside that range for this household — reassuring, but the agreement is a coincidence of these particular numbers, not a validation. Change the mortgage to zero and DIME gives $800,000, at the very bottom of the multiple range; change the years to 20 and DIME gives $1,850,000, far above it. The multiple cannot see a mortgage, debts, savings or existing cover, so it agrees with DIME only when those happen to cancel out. When the methods disagree, the needs figure is the one you can defend line by line, because every dollar in it names a job the money would have to do.
Redoing the number when life changes — and the cover trap
The amount this page produces is only as current as the life it describes, and lives change in exactly the ways that move DIME’s letters. A marriage, a child, a new mortgage, a new job: each one rewrites at least one input, and the honest response is to re-run the calculator rather than to keep trusting last year’s answer. A new mortgage adds its balance to the need dollar for dollar. A child adds education costs and usually lengthens the income-replacement years. A promotion raises the income to replace. Paying off the mortgage removes a whole letter. None of these changes is subtle in the arithmetic — each moves the answer by the full amount of the change — which is why the page’s advice to redo the amount whenever life changes is not boilerplate but the most practical instruction on it.
One trap deserves special attention, because the page itself flags it in the form: cover provided through an employer usually ends, or becomes expensive to keep, when you leave that job. Counting employer cover at full value in the “cover already in place” box therefore flatters the answer in exactly the situation where the family would need it most — after a job loss that coincides with the worst moment. If your existing cover is mostly employer-provided, run the calculator twice: once with it counted, once without it, and treat the gap between the two answers as the size of the risk you are carrying on your employment. The same caution applies in reverse to savings: only count money the family could actually draw on. Retirement savings earmarked for a surviving spouse’s own old age are not the same as money available to clear debts and keep the home, and counting them twice — once as retirement provision and once as cover — understates the need.
Finally, keep the two steps of this decision separate. This page answers only the first: how much protection the family’s obligations point to. The second step — what that protection costs per month, for what kind of policy, over what term — needs your real details and an insurer’s underwriting, and no site can take you from the amount to a price without guessing at your health on your behalf. Work out the amount honestly first, with the letters itemised and the existing position subtracted in full; then take that amount, not a slogan multiple, into the pricing conversation. A needs figure you can defend line by line is a stronger negotiating position than any rule of thumb, and it is also the figure your family would actually have to live on.
The letters people get wrong
Each letter of DIME has a characteristic mistake, and most of them move the answer by exactly the amount of the mistake — which is why getting the letters right matters more than getting the method’s name right. Debts means everything owed except the mortgage, which has its own letter: cards, loans, and any other balances the family would have to clear. Counting the mortgage inside debts as well would double-count it, adding the same $250,000 twice and inflating the default answer from $1,050,000 to $1,300,000 for no reason. The form keeps the two boxes separate precisely so that error cannot hide: debts in one box, mortgage in its own.
Income replacement is the letter where optimism and pessimism both cost money. Too few years and the family runs out of income while still needing it; too many and you are buying cover for years the family would have been self-sufficient. The page suggests ten years as a common starting point, often until the youngest child is grown, but that is a starting point for thinking, not a recommendation for your household. Work it out from your own timeline: how many years until the youngest child is independent, until a spouse’s own income could carry the household, until the mortgage would have been paid anyway. Then remember the scaling rule from the table above: each extra year adds exactly one year’s income — $80,000 in the default — to the need, so a five-year error in either direction is a $400,000 error in the answer.
Education and future costs mean costs already planned and promised, not every imaginable expense: college funds and other big planned costs the household had actually intended to cover. And there is one more box that is easy to miss because it starts blank: final expenses. It is optional, and leaving it blank simply leaves it out — but entering $10,000 for funeral and end-of-life costs raises the default total need from $1,200,000 to $1,210,000 and the additional cover from $1,050,000 to $1,060,000, dollar for dollar like every other letter. If those costs would otherwise fall on the family at the worst possible moment, they belong in the calculation; if they are already provided for elsewhere, they do not. Either way, the decision should be conscious, not an accident of a blank box.
One final check before you treat any DIME figure as final: add the letters up by hand, once, from the calculator’s own breakdown. Debts plus income times years plus mortgage plus education, minus savings and existing cover, should reproduce the total need and the additional cover exactly — $50,000 plus $800,000 plus $250,000 plus $100,000 is $1,200,000, minus $150,000 is $1,050,000 on the default household. If your hand total disagrees with the screen, an input is not what you think it is: a blank box you meant to fill, a mortgage entered under debts as well, an employer’s cover counted twice. The calculator is a fast adding machine for a judgement you must make yourself, and the one-minute hand check is what keeps the judgement honest.
Needs analysis beats rules of thumb
Ten times income is a starting point that fails exactly where it matters: a mortgaged family with young children routinely needs far more. The honest arithmetic is immediate expenses plus debts plus present-valued income replacement plus future obligations (education, childcare), minus savings and existing cover — including employer group cover, which usually ends with the job. A worked example ($80,000 earner, $250,000 mortgage, two young children) gives about $1.4 million of need against an $800,000 rule-of-thumb figure. The gap between those numbers is the point of doing the analysis.
Term for working years, whole life for permanent needs
Term life buys maximum protection per dollar for a fixed period — the right shape for income replacement while a mortgage runs and children depend on you. Whole life costs 5–15 times more for the same face amount, adds lifelong coverage and a cash value, and earns its place only for permanent needs: a lifelong dependant, estate liquidity, or business succession. Buying term and investing the premium difference independently usually leaves more money than the cash value inside a whole-life policy.
Frequently asked questions
How much life insurance do I actually need?
There is no single right number, but there is a defensible way to build one: add up what the money would have to do. That is the DIME method — your debts, the income your family would lose (your yearly income times the number of years they would need it), your mortgage balance, and education or other future costs — then subtract savings and any cover you already have. On this page’s example — $50,000 of debts, $80,000 of income replaced for 10 years, a $250,000 mortgage and $100,000 of education costs, with $150,000 already in place — the answer is $1,050,000.
What is the DIME method?
DIME is a needs-based formula used by financial educators: Debts plus Income replacement plus Mortgage plus Education. Each letter is a job the payout would have to do if you died: clear what you owe, stand in for the pay cheques that stop, keep the roof, and fund the plans you had already made for your children. Because it starts from your actual obligations rather than a slogan, its answer can be far above or far below the usual rules of thumb — which is exactly why it is the headline method on this page.
Why do people say I need 10 to 15 times my income?
It is a shortcut from a time when one income often carried a whole household: ten to fifteen years of pay roughly replaced that income until children were grown and the mortgage was mostly gone. It is quick, and this calculator shows it as a range next to the DIME answer. But it ignores your actual debts, your mortgage, your savings and any cover you already hold, so it overshoots for some households and badly undershoots for others. Treat it as a sanity check, not the answer.
Will this calculator tell me what a policy costs?
No, and it is important to understand why. This page works out an amount of cover — a number of dollars of protection. The price of that protection, the premium, is set person by person from age, health, medical history, habits, the type of policy and how long it runs. The same $1,050,000 of cover can cost very different amounts for two different people, so no honest calculator can quote a price from coverage alone, and this one does not try.
Should I subtract cover I already have?
Yes — that is the offset step, and skipping it is the most common reason people overestimate what they need. Savings and investments your family could draw on, and existing cover such as a policy of your own, all reduce the gap a new policy would have to fill. One honest caution: cover provided through an employer usually ends, or becomes expensive to keep, when you leave that job, so many people count it at less than face value or leave it out of the offset entirely.
Why is the mortgage counted separately from other debts?
Because it is usually the largest single obligation a family carries, and it behaves differently: if the mortgage is cleared, the family can stay in the home on a much smaller income. DIME gives it its own letter, M, apart from everyday debts like cards, car loans and student loans, so you can see exactly how much of your cover number is really just the house. If your mortgage is already counted inside your debts figure, set the mortgage field to zero to avoid counting it twice.
Why does doubling the years not double the answer?
Because only one letter scales. Raising the replacement period from 10 years to 20 years lifts the income part from $800,000 to $1,600,000, but debts, mortgage and education stay exactly where they were — so the total need rises from $1,200,000 to $2,000,000 and the additional cover from $1,050,000 to $1,850,000, not to double. The years input is usually the largest part of the need, which is why it deserves more thought than any other box: it encodes how long the family would actually need the income.
What if I have no mortgage at all?
Then that letter drops out and the answer falls by exactly the mortgage balance. On the default household, setting the mortgage to $0 takes the total need from $1,200,000 to $950,000 and the additional cover from $1,050,000 to $800,000, with nothing else moving. The mortgage is counted separately from other debts because keeping the home is a distinct job from clearing loans and cards — a family can be debt-free and still lose the house if the mortgage is not covered.
Can the recommended cover really be zero?
Yes, and it means the need this method calculates is already covered, not that the calculator is broken. With $1,200,000 of savings, the household has $1,250,000 in place against a $1,200,000 need — $50,000 more than DIME asks for — so the answer is $0 rather than an invented gap. Cover bought on top of a zero would be bought for reasons outside this calculation, such as a larger legacy or a different method’s answer, and the page says so plainly instead of manufacturing a number.
Should I count my employer’s cover at full value?
Be careful. Cover provided through an employer usually ends, or becomes expensive to keep, when you leave that job — which is exactly when a family might need it most. Run the calculator twice, once with employer cover counted and once without, and treat the gap between the two answers as the size of the risk you are carrying on your employment. Only count money and cover the family could actually draw on if the worst happened.
How much life insurance do I need?
Immediate expenses + debts + present-valued income replacement + future obligations − savings and existing cover. For a mortgaged family with young children, $1–1.5 million is common.
Term or whole life?
Term for most families: most protection per dollar during working years. Whole life for permanent needs (lifelong dependants, estate liquidity) at 5–15× the premium.
What drives the premium?
Age most of all, then health classification, smoking (roughly doubles to triples premiums), coverage amount, term length, and gender. Buy younger and healthier for the lowest price.
Is the payout taxable?
Generally no federal income tax to the beneficiary on the face amount; interest on delayed payment is taxable, and large estates face separate questions.
