If you've ever searched this question, you've probably hit one of two unhelpful answers: a vague "it depends" or a one-size rule of thumb like "ten times your income." The rule of thumb is a fine starting point, but your family isn't a thumb. This post gives you the actual framework — the same logic a needs analysis follows — so you can build a number that fits your household, not a generic one.
We'll size life coverage first, then disability income, then translate the most common product question — term vs. permanent — into plain English. By the end you'll be able to do this on the back of an envelope, and then check your math in a couple of minutes with our calculator.
The core idea: replace a role, not a paycheck
When you size life insurance for a family, you're not buying back a single year of salary. You're answering a harder, kinder question: if this income disappeared, what would it take for the people who depend on it to stay on their feet for the years ahead?
That breaks into a short list of buildable pieces. Add them up, subtract what you already have, and the remainder is your gap.
Coverage need = Income replacement + Mortgage + Childcare + Education + Final expenses − (existing coverage + liquid assets)
Let's walk each one.
1. Income replacement
This is usually the largest piece. A common approach is to replace ten to fifteen years of the take-home income a household relies on. Why a range? Because younger families with small kids generally need a longer runway, while families closer to the kids' independence need less.
A simple version: annual income your family depends on × the number of years until your youngest is grown and the surviving parent is re-established. For a $70,000 income with young children, ten to fifteen years lands around $700,000–$1,050,000 just for this piece.
2. Mortgage (and other major debt)
The goal here is simple and human: don't force a grieving family to move. Add your remaining mortgage balance so the home is secure. Roll in other large balances too — a car loan, any private student or personal debt — so nobody inherits a payment they can't carry alone.
3. Childcare and household work
If two parents are sharing the labor of raising kids, losing one doesn't just remove income — it removes hands. The surviving parent may need to pay for childcare, after-school care, or help around the house that nobody used to be paid for. Estimate a realistic annual cost and multiply by the years your kids will need it.
4. Education
If college (or trade school, or whatever path your kids choose) is part of your plan, include a reasonable estimate per child. You don't need to fund the most expensive scenario imaginable — just enough that an unexpected loss doesn't quietly erase the future you were building toward.
5. Final expenses and a buffer
Add a cushion for end-of-life costs and a few months of breathing room — the space for the surviving spouse to grieve, settle the estate, and make decisions slowly instead of under financial pressure. This is the line item spreadsheets forget and families remember.
Then subtract what you already have
Finally, subtract your existing coverage (including any group life through work — typically one to two times salary) and liquid assets you'd actually use for this, like emergency savings. The number left over is your gap. That's the figure worth focusing on.
A worked composite
Meet the Adichie household in Texas (a composite illustration, not a real client). One spouse earns $80,000, the other works part-time; two kids, ages 4 and 7; a mortgage with $240,000 remaining.
- Income replacement (12 years × ~$60,000 relied-upon): ~$720,000
- Mortgage payoff: $240,000
- Childcare/household support (8 years × ~$12,000): ~$96,000
- Education (2 kids, modest estimate): ~$120,000
- Final expenses + buffer: ~$30,000
- Subtotal need: ~$1,206,000
- Less existing group coverage (1.5× salary ≈ $120,000) and emergency savings (
$25,000): **$145,000** - Estimated gap: ~$1,061,000
Rounded, the Adichies might look at roughly $1,000,000–$1,100,000 of additional life coverage. Your numbers will differ — and that difference is exactly why the framework beats a flat rule of thumb.
Don't forget the paycheck itself: disability income
Life insurance protects your family if you're gone. Disability income coverage protects your family if you're here but can't work for a stretch — which is, statistically, the more likely interruption during your working years.
Sizing it is simpler. Most coverage is designed to replace a portion of your income — commonly around 60% — because benefits are often received tax-free, which narrows the gap to your take-home pay. The question to ask: if my paycheck paused for six months or two years, what would keep the lights on? Your income is the engine behind every other plan you have; this is the layer that protects the engine. Many families treat life and disability coverage as two halves of the same protection, not separate purchases.
Term vs. permanent, in plain English
Once you know your number, the next question is usually what kind of life insurance. The two broad families are term and permanent. Here's the honest, jargon-free version.
Term life insurance covers you for a set period — 10, 20, or 30 years — and is generally the most affordable way to get a large amount of coverage. You pick a term that matches your "high-need" window: the years with a mortgage and kids at home. It's clean and straightforward — coverage for a defined chapter of life. For most young families focused on closing a gap affordably, term does the heavy lifting.
Permanent life insurance (whole life and its relatives) is designed to last your whole life and can build cash value over time. It costs more per dollar of coverage because it's doing more than one job. It tends to fit specific goals — long-term estate or legacy planning, lifelong dependents, or a desire for a cash-value component — rather than the basic "protect my family during the mortgage years" need.
A common, sensible pattern: use term to cover the large temporary need, and consider permanent only if you have a specific lifelong goal it's designed to serve. Neither is "better" in the abstract. The right answer depends on what job you're hiring the coverage to do.
| Term life | Permanent life | |
|---|---|---|
| Lasts | A set period (10/20/30 yrs) | Your whole life |
| Relative cost | Lower per dollar of coverage | Higher (does more) |
| Builds cash value | No | Yes (designed to) |
| Common fit | Covering the mortgage-and-kids window | Lifelong needs, estate/legacy goals |
