How much life insurance should I have is one of the most common questions we hear, and it’s also one of the most commonly guessed at with an oversimplified rule of thumb (“10 times your income” or similar shortcuts). Those rules aren’t exactly wrong, they’re just imprecise. The average underinsured American household is short by roughly $200,000 in coverage relative to their actual need, according to LIMRA’s Insurance Barometer research.¹ A more accurate number comes from looking at your specific obligations and resources, not a multiple of salary alone.
Two Common Methods
The Income Multiple Method
This approach multiplies your annual income by a factor (commonly 7-10x) to estimate a death benefit. It’s sometimes useful as a rough starting point, but it doesn’t account for existing assets, debts, or specific future obligations like college tuition which is why we treat it as a sanity check rather than a final answer. Tying you life insurance to an objective also helps remind you why you are paying the premium, and helps you answer the question of should I continue to pay.
The DIME Method
A more precise approach typically adds up four categories of need:
- Debt – total non-mortgage debt that would need to be paid off (credit cards, loans, business debt)
- Income – years of income replacement needed, multiplied by annual income (often until retirement, or until children are grown)
- Mortgage – the remaining balance on your home mortgage
- Education – estimated future education costs for children or dependents
You then subtract existing liquid assets and any life insurance you already have (individual or group) from that total to arrive at the additional coverage needed.
There are MANY calculators online that can walk someone through an actual calculation but I prefer to keep it simple. Mostly because those online calculators usually tell people they need such a high amount of life insurance that it turns them off from the entire conversation. Focusing on your important goals rather than covering the entire risk is the direction we prefer to go.
A Simple Illustration
| Category | Estimated Amount |
| Remaining mortgage balance | $310,000 |
| Other debt (auto, credit cards) | $25,000 |
| Income replacement (10 years × $120,000) | $1,200,000 |
| Future education costs (two children) | $180,000 |
| Subtotal need | $1,715,000 |
| Less: existing group life coverage and liquid savings | −$165,000 |
| Estimated additional coverage needed | $1,550,000 |
This is illustrative only, your actual numbers and categories of what is important to you will differ, and factors like a spouse’s income, existing permanent policies, and retirement account balances all belong in a complete calculation.
Beyond the Basic Formula
A few situations call for numbers a standard formula won’t fully capture on its own:
- Business owners need coverage for personal income replacement separate from any business-owned key person or buy-sell coverage (see our earlier post in this series)
- Stay-at-home parents often underinsured or entirely uninsured, despite the real replacement cost of childcare, household management, and related services
- High-net-worth individuals may need coverage sized specifically for estate liquidity (covering estate taxes or settlement costs) rather than income replacement
- Special needs dependents may require lifelong coverage and coordination with a special needs trust
How Estate Size Affects the Calculation
For most households, life insurance need is driven by income replacement and debt, not estate tax exposure. The 2026 federal estate and gift tax exemption is $15 million per individual and $30 million for a married couple, following the amount made permanent under the One Big Beautiful Bill Act, so most estates won’t owe federal estate tax at all.²
But for business owners and high-net-worth individuals approaching or exceeding those thresholds or residents of the handful of states that impose their own, lower estate or inheritance tax exemptions the calculation shifts. Coverage may need to be sized to provide liquidity for taxes and settlement costs, not just income replacement for survivors.
| TAX NOTE — Estate tax exposure depends on your total estate value, state of residence, and ownership structure, and the rules can change. This is general information, not a substitute for a personalized projection from your CPA or estate planning attorney. |
Reviewing Your Number Over Time
Life insurance need isn’t static. A mortgage refinance, a new child, a business sale, a significant raise, or debt payoff can all shift the right number meaningfully in either direction. We recommend revisiting the calculation every few years, or after any major life or financial event, rather than treating a policy purchased at 30 as automatically correct at 45.
Carriers We Work With
Once your number is established, we place coverage across our panel of more than 40 carriers including Principal, Ameritas, North American, Pacific Life, Protective, Prudential, Lincoln Financial, and AIG to find the combination of price, underwriting approach, and policy design that fits your specific calculation.
Frequently Asked Questions
Is 10 times my income a good rule of thumb for how much Life Insurance I need?
It is useful as a starting point but might significantly overstate or understate your actual need which really depends entirely on your debt, dependents, existing assets, and time horizon. We use it only as a rough starting point, not a final answer.
What factors should I include to calculate how much life insurance I need?
That depends on the why behind the life insurance. For income replacement a goal-focused approach around desired outcomes is usually best. For estate planning we need to estimate what amount of tax you are estate is likely to need to pay. For buy-sell planning we need to plan for the valuation of the business at time of sale.
For the most common type, income replacement it usually comes down to debt, income replacement and educational expenses.
Do I need to recalculate how much life insurance I need every year?
No. Not every year, but we recommend a review every 3-5 years or after any major event such as a new child, a mortgage refinance, a business sale, or a significant income change.
The Takeaway
The right amount of life insurance is the amount that actually covers your specific obligations not a number pulled from a generic rule of thumb. A DIME-style calculation, revisited periodically, gets you far closer to the right figure than a simple income multiple alone.
