How Much Term Life Insurance Do I Need?

Term life insurance does one job: if you die during your working years, it replaces the income your family was counting on. Because the coverage lasts a set window (10, 15, 20, or 30 years), it delivers the most protection per dollar of any life insurance product, which is exactly why it's the foundation of the plan rather than the whole plan.
The two decisions that matter are the amount and the term length. Get those right and the product is simple; get them wrong and your family is either underprotected or you're paying for coverage that outlives its purpose.
This guide gives you the sizing math we use with clients, a clean way to pick the term length, what coverage actually costs at ages 35-55, and the conversion feature that quietly connects your term policy to the rest of your plan.
The sizing math: start at 10-12x income, then adjust
The standard starting point is 10-12 times your annual income. For a household earner at $150,000, that's $1.5-$1.8 million, a number that surprises people until they do the arithmetic: invested prudently, a $1.5 million benefit replaces roughly $60,000-$75,000 a year of income for two decades. That's what 'replacing your income' actually requires.
Then adjust for your specifics: add the mortgage balance if you want it retired outright, add roughly $100,000-$200,000 per child for college if that's a goal, and subtract liquid savings and existing coverage. Group coverage through work counts, but only while you work there, which is why we treat employer coverage as a bonus rather than the foundation.
- Start: 10-12 × annual income
- Add: mortgage payoff, education goals, outstanding debts
- Subtract: liquid savings, investments, existing personal coverage
- Discount employer coverage; it doesn't follow you out the door
Choosing the term length
Match the term to your longest obligation, not your age. If your youngest child is 3, you have a 20-year obligation. If you just signed a 30-year mortgage, you have a 30-year obligation. When the obligations disagree, the honest answer is often two policies: say, $1 million for 30 years covering the mortgage and baseline, stacked with $500,000 for 15 years covering the expensive child-raising window.
Laddering like this costs less than buying the full amount for the full term, and it means coverage steps down as obligations do, which is the plan working as designed, not a gap.
What it costs at 35-55
Term life is cheaper than most professionals guess. As an illustrative, non-tobacco ballpark: a healthy 35-year-old woman might pay roughly $45-$60 a month for $1 million of 20-year coverage; a healthy 45-year-old man might pay roughly $110-$150 for the same policy. Rates rise about 8-10% for every year of age, and a 30-year term costs meaningfully more than a 20, but locking a 30-year rate at 38 usually beats buying a second policy at 58.
Health class moves the price more than any other factor after age. Well-managed blood pressure or cholesterol often still earns a preferred class with the right carrier, and 'the right carrier' is the operative phrase, because each one draws its class lines differently. The same applicant routinely gets quoted 30%+ apart by two carriers for identical coverage.
The conversion privilege: your option on the future
Most quality term policies include a conversion privilege: the right to convert some or all of the coverage into a permanent policy (with the same carrier, at your original health class) without new underwriting. If your health changes at 50, that option is worth more than everything else in the contract.
Conversion is also how the term piece connects to the accumulation piece of your plan. Some clients convert a slice of term into permanent coverage in their 50s as the mortgage falls away; others simply let the term lapse when the obligations are gone because their IUL already carries the permanent load. Either way, check the conversion window before you buy; many carriers limit it to the first 10-20 years of the term or to before age 65 or 70.
The mistakes that cost families the most
The first is rounding down to a comfortable-sounding number. A $250,000 policy feels substantial and replaces less than two years of a $150,000 income. Size the coverage to the job it has to do, then adjust the term length or ladder to fit the budget.
The second is relying on group coverage. The typical employer policy is 1-2x salary and ends when the job does, often exactly when a health change makes personal coverage expensive. Buy your own base layer while you're healthy; treat work coverage as a supplement.
The third is waiting. Every year of age adds roughly 8-10% to the premium, and a single health event can move you a class or two permanently. The rate you qualify for today is the cheapest it will ever be.
The bottom line
Size the coverage at 10-12 times income adjusted for your mortgage and goals, match the term to your longest obligation (laddering when obligations disagree), insist on a conversion privilege, and buy at your current age rather than a future one. For most professionals in their 30s and 40s, the right term policy costs less per month than a streaming bundle, and it's the piece of the plan your family would feel the absence of most.
Common Questions
Income Protection questions, answered
Is term life insurance a waste of money if I outlive it?
No more than car insurance is wasted if you never crash. You're paying for protection during the years your family depends on your income, and the low cost is what makes adequate coverage affordable.
Should I buy one big policy or ladder two?
If your obligations expire on different schedules (a 30-year mortgage but 15 years until the kids are independent), laddering two policies usually delivers the same protection for less total premium. Your agent can price both structures side by side.
Does my employer's life insurance count toward my number?
Count it while you have it, but don't build on it. Group coverage is typically 1-2x salary, ends when you leave, and usually can't be taken with you at a reasonable price. Your personal policy is the foundation; work coverage is a bonus.
Is there a deadline to convert a term policy to permanent coverage?
Usually, yes. Most carriers only allow conversion during the first 10-20 years of the term or before a set age, often 65 or 70, whichever comes first. Check the conversion window before you buy, because a generous one costs nothing up front and can be worth a great deal if your health changes later.
