“How much life insurance do I need?” is one of those questions most people answer with a shrug and a round number. Maybe a coworker said $500,000. Maybe an online ad suggested ten times your salary. The trouble is that your family’s real number could be far higher, or much lower, than either guess.
The good news: you don’t need a financial planner to get close. With a notepad, your last few bank statements and about 20 minutes, you can work out a figure that actually fits your life. This guide walks you through it, step by step, with a real-world example at the end.
Your coverage should replace the money your family would lose, not hit a magic multiple of your salary.
Add up income replacement, debts, future costs and final expenses, then subtract what you already have.
Stay-at-home parents need coverage too, because replacing their work costs real money.
Review your number after big life changes like a new baby, a new home or a pay rise.
Why the “10 times your salary” rule falls short
Rules of thumb are popular because they’re quick. The most common one says to buy coverage worth 10 to 12 times your annual income. It’s not a terrible starting point, but it ignores almost everything that makes your situation unique.
A 30-year-old with a new mortgage and two toddlers needs far more protection than a 55-year-old whose house is paid off and whose kids have moved out, even if they earn the same salary. A multiple can’t see your debts, your savings or how many years your family would rely on your paycheck.
That’s why a needs-based calculation works better. You build the number from the ground up.
How much life insurance do I need? The 4-part method
Grab a pen and work through each of these. Be honest, and round up where you’re unsure.
1. Income your family would need to replace
Ask yourself how many years your family would depend on your income. For many parents, that’s until the youngest child finishes school or becomes financially independent.
Take your take-home pay, not your gross salary.
Your household may need a bit less without you (often 70 to 80 percent), since there’s one less person to feed and insure.
Multiply that yearly figure by the number of years of support needed.
2. Debts you’d leave behind
List everything you owe that your family would have to keep paying:
Mortgage balance
Car loans
Credit cards and personal loans
Any student loans that wouldn’t be forgiven
Clearing the mortgage is often the single biggest gift a policy can give. It means your family keeps the house without the monthly payment hanging over them.
3. Future costs you’ve planned for
Think about the big expenses that were going to come out of your future income. College or university tuition is the obvious one. Childcare is another, especially if your partner would need to work longer hours.
4. Final expenses
Funerals, legal fees and estate costs add up quickly. Setting aside $10,000 to $20,000 (or the local equivalent) covers most situations.
Then subtract what you already have
Once you’ve totaled the four parts, take away resources your family could already draw on:
Savings and investments (excluding money earmarked for retirement, if you’d rather not touch it)
Existing life insurance, including any policy through your job
Any lump sum your spouse or partner would receive from a pension or government benefit
The number that’s left is your coverage gap. That’s roughly how much life insurance you should buy.
A worked example: meet Sam
Numbers make more sense with a real face attached. Sam is 35, takes home $70,000 a year, and has two kids aged 4 and 7. Here’s how Sam’s calculation looks:
Item
Amount
Income replacement: $49,000 (70% of $70,000) × 15 years
$735,000
Mortgage balance
$280,000
Car loan
$15,000
Education fund: $50,000 per child
$100,000
Final expenses
$15,000
Total needs
$1,145,000
Minus savings
−$40,000
Minus workplace policy (2× salary)
−$140,000
Coverage gap
$965,000
Sam would round up to a $1 million policy. Notice that the “10 times salary” rule would have suggested $700,000, leaving Sam’s family about $265,000 short. That’s a mortgage-sized hole.
Don’t forget the stay-at-home parent
One of the most common gaps we see is a family that insures only the earner. If a parent who handles childcare, school runs and the household died, the surviving partner would suddenly need to pay for those services.
Full-time childcare alone can run well into five figures a year in the US, UK and Canada. A stay-at-home parent’s policy should cover those costs until the children are old enough to need less help.
Quick notes for US, UK and Canadian readers
United States: Death benefits paid to a named beneficiary are generally free of federal income tax. Employer group life is often just one or two times salary and usually ends when you leave the job.
United Kingdom: Many employers offer “death in service” benefit, often two to four times salary. Payouts can count toward your estate for Inheritance Tax unless the policy is written in trust, so ask your adviser about setting one up.
Canada: Life insurance proceeds paid to a named beneficiary are generally tax-free. Group coverage through work tends to be modest, so many Canadians top it up with an individual term policy.
Matching the policy length to your needs
Once you know your number, think about how long you need it. Most of the needs above shrink over time: the mortgage gets paid down, kids grow up and savings build.
That’s why term life insurance is the right fit for most families. A 20- or 25-year term often lines up neatly with a mortgage and the kids’ school years. Some people “ladder” two smaller policies with different lengths, such as a 30-year policy for the mortgage and a 15-year policy for childcare years, to save on premiums.
Relying only on your work policy. It’s usually too small and disappears if you change jobs.
Forgetting inflation. $50,000 for college today won’t cover the same costs in 15 years.
Setting it and forgetting it. A new baby or a bigger house can change your number overnight.
Over-insuring. Buying far more than you need means higher premiums that could be going into savings.
When to get a second opinion
The method above works well for most households. If you own a business, support an adult dependent, have a blended family or a large estate, it’s worth talking to a professional. A good independent agent can compare several insurers at once. Here’s how to choose a life insurance agent and the questions to ask before you sign.
Your next step
So, how much life insurance do you need? Enough to replace your income for the years your family depends on it, clear your debts, cover the big costs ahead and pay for final expenses, minus what you already have. Run the four-part method tonight, write the number down, and get two or three quotes this week. Twenty minutes now could give the people you love real financial breathing room later.
Frequently asked questions
Is $500,000 of life insurance enough?
It depends entirely on your debts, income and dependents. For a single person with no kids, it may be more than enough. For a young family with a mortgage, it often falls short. Run the calculation above to find out.
Do I need life insurance if I’m single?
If no one relies on your income and your debts would not pass to anyone else, you may need little or none. A small policy for final expenses can still spare your relatives the cost.
How often should I review my coverage?
Check it every few years and after any major life event, such as marriage, divorce, a birth, a home purchase or a big change in income.
