Quick Answers

Life Insurance Need Calculator, in 30 seconds.

Direct answers to the most common questions, in plain language. Skim if you're in a hurry; dig deeper below.

How much life insurance do I really need?

Answer

Use the DIME method — typically 10–15x your income.

The DIME method totals four real obligations: Debts, Income replacement, Mortgage, and Education for your kids. For most working parents with a mortgage and young kids, the answer lands between 10x and 15x annual income — much higher than employer-provided coverage alone.

Is 10x income enough life insurance?

Answer

It is a starting point, not a final answer.

10x income is a fast rule of thumb, but it ignores mortgage size, number of kids, and existing debt. DIME usually lands higher for parents with a mortgage and lower for single, debt-free earners. Run both and use the larger of the two.

Is term or whole life insurance better?

Answer

Term, for almost everyone solving the "need" question.

Term life is cheap, simple, and lasts as long as your dependents need protection. Whole life mixes insurance with a slow-growing investment, costs 8–12x more per dollar of coverage, and is rarely the right tool for replacing income.

Do I still need life insurance if my employer provides some?

Answer

Usually yes — employer coverage is small and not portable.

Group life is typically 1–2x salary and disappears the day you leave the job. For a family with a mortgage and young kids, that's usually a fraction of true need. Treat it as a bonus on top of an individual term policy.

How it works

How life insurance need calculator works.

The mechanics in short answers — no jargon, no upsell.

01

Replace income for the years your family depends on it.

Multiply annual income by the years of replacement (10–20 is common). This is the largest single bucket for most working parents.

02

Pay off the mortgage and any other debts.

A surviving partner should not be juggling a mortgage, car loan, and student debt on one income. Add the full balances to the policy.

03

Fund each child's education.

A four-year degree is the most common goal. Estimate per-child cost in today's dollars and multiply by the number of kids.

04

Cover final expenses, then subtract existing coverage.

Add $10–20k for final expenses, then subtract whatever you already have from employer or individual policies. The gap is what you actually need to buy.

How to use

Four steps. About 20 seconds.

Designed so anyone can model their situation in under a minute, with or without a finance background.

  1. Step 1
    Enter your annual income and years to replace
    Use gross income. Years to replace is typically until your youngest is independent.
  2. Step 2
    Add your mortgage balance and other debts
    Outstanding mortgage, car loans, student loans, credit cards — anything that wouldn't vanish.
  3. Step 3
    Add kids and per-kid education cost
    Use today's dollars. The default is roughly the all-in cost of a public four-year degree.
  4. Step 4
    Subtract existing coverage to find the gap
    Include employer group life and any existing individual term policies. The gap is your shopping target.

Written for borrowers, not bankersPlain-language, jargon-freeReviewed quarterly
What is the DIME method?

DIME stands for Debts, Income, Mortgage, and Education. You add the four numbers to estimate your total life insurance need, then subtract existing coverage to find the gap. It's more accurate than a simple income multiple because it accounts for your actual obligations.

Is the 10x income rule accurate?

10x income is a quick screen but ignores mortgage size, debt load, and number of children. For most parents with a mortgage and kids under 10, DIME comes out higher. For single earners with no dependents, DIME is often much lower. Use the higher of DIME and 10x.

How many years of income should I replace?

A common answer is "until your youngest child is financially independent." For parents of young kids, that's often 15–20 years. For parents of teens, 5–10 years may be enough. Pair the number with the years remaining on your mortgage as a sanity check.

Do I need life insurance if I have no dependents?

Usually no. If no one relies on your income — no spouse, no kids, no aging parents you support — a small policy for final expenses is typically enough. Life insurance is income replacement; without dependents there is no income to replace.

Should I count my spouse's income?

Yes, indirectly. If your spouse earns enough to cover the family's needs alone, your "income to replace" number can be smaller. If both incomes are essential, both partners should typically carry policies sized to their own DIME total.

How long should my term life policy last?

Match the term to the years you're replacing. A 30-year-old parent of newborns usually needs a 20- or 30-year term. A 50-year-old with a paid-off house and grown kids may not need new coverage at all.

Does life insurance cover education costs?

It can — that's the "E" in DIME. The death benefit is a lump sum your family can invest and draw from for tuition. Add roughly the cost of a four-year degree per child, in today's dollars, to the total.

Is term life insurance enough?

For solving the "need" calculated here, yes. Term life delivers the largest death benefit per dollar of premium, which is exactly what you want for income replacement. Whole and universal life products serve different goals (estate planning, forced saving) and cost much more.

The DIME method, in plain English.

DIME is just four numbers added together. Debts you'd leave behind. Income your family needs to replace. Mortgage balance that still has to get paid. Education for your kids. Sum those four, subtract whatever life insurance you already have, and you have a real coverage target — not a rule of thumb.

The reason it works better than "10x income" is that it forces you to look at your actual financial life. A renter with no kids and a 30-year career ahead has a very different real number than a homeowner with two toddlers, even at the same income.

10x income vs DIME — which should you use?

The 10x rule is a screening tool. It's good for a five-second answer at a dinner party. DIME is a planning tool. It's what you should actually buy from.

In practice, run both. If DIME is materially higher, trust DIME — you have obligations the rule of thumb doesn't see. If 10x is higher, your obligations are lighter than your income implies, and the larger number is still a safe ceiling. Either way, you want to be above the higher of the two, not below the lower.

Term vs whole life — why this calculator assumes term.

A 30-year term policy for a healthy 35-year-old can be cheap — often $30–60/month for $1M of coverage. The same coverage in whole life can run $700–1,200/month, because most of the premium goes to a cash-value account, not the death benefit.

If your problem is "I need to make sure my family is fine if I die," term wins on math, simplicity, and flexibility. Whole life solves different problems — estate planning, lifelong coverage for special-needs dependents, certain business structures — that the DIME calculation doesn't address.

Why employer coverage is rarely enough.

Group life through work is convenient and often free up to 1x salary, but it disappears the day you leave the job. For a parent with a 20-year horizon, that's a thin reed to lean on.

Use employer coverage as a bonus layer. Buy an individual term policy sized to your DIME number, owned by you, portable across jobs, and locked at today's rates and today's health.

When you don't need life insurance.

  • You have no dependents and no shared debt.
  • Your assets already exceed the DIME number — you're self-insured.
  • Your kids are financially independent and your mortgage is paid off.
  • You're buying whole life as a "forced savings" mechanism — there are better tools.
  • Your only motivation is "in case something happens" — be specific about who, exactly, would suffer financially, and how much.
