How much life insurance do I need?
There's no exact answer, only estimates of what your family would need. The National Association of Insurance Commissioners (NAIC) says the amount depends on the financial needs that continue after your death, such as supporting your family, paying for education, and paying off a mortgage. Here's how the common methods compare on the example above.
| Method | Total need | Gap |
|---|---|---|
| DIME | $1,655,000 | $1,505,000 |
| Income replacement, present value | $1,245,487 | $1,095,487 |
| 5 times income | $425,000 | $275,000 |
| 8 times income | $680,000 | $530,000 |
The NAIC notes that some suggest five to eight times income, and says working through your needs gives a more accurate amount. On this example, that shortcut comes in far below both methods, because it can't see the mortgage or the years of support you have in mind.
How the DIME method works
DIME is a checklist: Debts, Income, Mortgage, Education. Add them up, then subtract what you already have. It's a rule of thumb that's easy to do on paper and hard to do wrong, and it counts every year of income at full value.
DIME need = debts and final costs + (income × years) + mortgage + educationHere that's $15,000 of debts plus $15,000 of final costs, $85,000 × 15 years, a $250,000 mortgage, and $100,000 of education. The total is $1,655,000. Less $150,000 you have, the gap is $1,505,000.
DIME tends to run high. It assumes your family needs all of your income, though your own spending and taxes would stop, and it gives no credit for what the payout could earn.
How income replacement and present value work
Income replacement asks what lump sum today could fund a share of your income for a set time. A payout earns a return while it's spent, so it takes less than the simple total. Funding $63,750 a year (75% of income) for 15 years, rising 2.5% a year, takes $865,487 at a 4% return, against $956,250 with no growth or return. Add the same debts, mortgage, and education, and the need is $1,245,487.
Present value = yearly need × (1 − q^years) ÷ (1 − q), where q = (1 + growth) ÷ (1 + return)| Years of support | 2% | 3% | 4% | 5% | 6% |
|---|---|---|---|---|---|
| 5 | $252,463 | $247,585 | $242,892 | $238,375 | $234,027 |
| 10 | $511,175 | $489,218 | $468,765 | $449,692 | $431,886 |
| 15 | $776,290 | $725,043 | $678,813 | $637,022 | $599,166 |
| 20 | $1,047,967 | $955,199 | $874,144 | $803,088 | $740,594 |
| 25 | $1,326,369 | $1,179,824 | $1,055,789 | $950,303 | $860,165 |
| 30 | $1,611,661 | $1,399,048 | $1,224,707 | $1,080,807 | $961,257 |
The discount rate is the input to watch. Your family's money may sit somewhere safe rather than in stocks, so a high rate can understate the need. Using 2% instead of 4% moves this gap from $1,095,487 to $1,219,770.
What makes the estimate too high or too low
- Unpaid work. A parent with no paycheck can still leave a real cost behind. The NAIC mentions child care. At $40,000 a year of unpaid work and the same other inputs, the gap is $637,288 to $830,000. Enter it under advanced options.
- Double counting. Paying off the mortgage and also replacing most of your income can count the same dollars twice. With no mortgage and a 60% replacement share, income replacement falls to $672,389.
- Other income. A spouse's pay lowers the need. $40,000 a year brings income replacement to $552,436. Social Security may also pay benefits to a surviving spouse or an unmarried child under 18 who qualifies, and you can enter that here if you know the amount.
- Coverage through work. The NAIC says it's usually less than you need, and you may not be able to take it with you when you leave. Count it, but test the result without it.
- Savings you've counted. Retirement accounts may be taxed when withdrawn, and your spouse may need them later. Count only what your family could really use.
One thing does work in your family's favor. The IRS says life insurance proceeds paid because of the insured person's death generally aren't taxable income, though any interest on them is. That's why this tool doesn't add tax on the payout.
Does the amount I need change over time?
Yes. The income side shrinks each year as fewer years of support remain, and debts usually fall too. The NAIC suggests reviewing your coverage after events such as a marriage, a birth, or a job change.
| Years from now | Income replacement | DIME |
|---|---|---|
| 0 | $1,095,487 | $1,505,000 |
| 5 | $906,215 | $1,080,000 |
| 10 | $626,425 | $655,000 |
| 15 | $230,000 | $230,000 |
Why this calculator doesn't show premiums
Because a real premium depends on your age, your health, the policy, and the insurer, and a made-up number would help no one. This tool also doesn't recommend a product. It gives you a figure to take to quotes. The NAIC says to make sure you can pay the premium both now and later, and to ask what the highest premium could be to keep your coverage.
An insurance agent, financial advisor, or company representative can review your needs, as the NAIC notes, and your state insurance department can answer questions about an agent or a policy. Keep in mind that someone selling a policy earns money from the sale. To see what your family spends now, try the budget calculator, and read building a budget that holds.
Common questions
What is a good rule of thumb for life insurance?
The NAIC mentions five to eight times income as something some suggest, which is $425,000 to $680,000 on $85,000. DIME and income replacement take more of your life into account. All three are rules of thumb.
How do I calculate how much life insurance I need?
Add your debts, mortgage, education costs, and the income your family would need. Then subtract your coverage and usable savings. The calculator does that both with and without a discount rate, so you can see the range.
What if I have no dependents?
You may need little or none. Ask who would be stuck with your debts or final costs. Set the years of income to zero, and the tool counts only those.
Does this tell me what life insurance costs?
No. We don't estimate premiums, and we don't ask for your contact details. Once you have an amount, get quotes from insurers or a licensed agent.
