Doubling coverage adds only 70 to 90 percent to the premium. Which amount does your household need?
Going from $500,000 to $1,000,000 of 20-year term life insurance typically adds $16 to $55 per month at ages 30 to 45. Life insurance is priced on a per-thousand-dollar basis with some volume efficiency, so doubling coverage does not double the cost. For households with significant income, mortgage debt, and young dependents, the extra coverage often justifies the additional premium. The right amount is what your coverage calculation produces, not whichever round number sounds comfortable. These are general estimates for healthy, non-smoking applicants; actual premiums vary by carrier and health class. Consult a licensed insurance agent. This is not financial advice.
Many people assume that doubling coverage from $500,000 to $1,000,000 doubles the premium. It does not. Life insurance is priced on a per-thousand-dollar basis with some volume efficiency, so the jump from $500k to $1 million typically adds 70 to 90 percent to the premium rather than 100 percent. For many households, the extra protection is worth considerably more than the additional monthly cost.
The comparison below assumes a healthy, non-smoking applicant in a standard or preferred rate class buying a 20-year term policy at the ages shown. Use the life insurance coverage calculator to see current estimates for your specific age and health profile.
| Age | $500,000 (est. monthly) | $1,000,000 (est. monthly) | Extra per month |
|---|---|---|---|
| 30 | $22 to $35 | $38 to $60 | $16 to $25 |
| 35 | $28 to $42 | $48 to $72 | $20 to $30 |
| 40 | $45 to $70 | $78 to $125 | $33 to $55 |
| 45 | $75 to $120 | $130 to $210 | $55 to $90 |
For a 35-year-old, the extra $500,000 of coverage costs roughly $20 to $30 more per month. Over a 20-year term that amounts to $4,800 to $7,200 in additional premiums to protect a half-million dollars more. Whether that trade-off makes sense depends on your individual obligations and financial situation.
For some households, yes. For others, no. A $500,000 policy is often sufficient for a single earner with moderate debt, a partly paid-down mortgage, and children approaching independence. It may fall short for a household with a high earner, a large remaining mortgage, young children, and a surviving spouse with substantially lower earnings. Run the DIME calculation (Debt, Income replacement, Mortgage, Education, minus savings and existing coverage) to find your actual target. If the result is $700,000 or more, a $1 million policy is often the cleaner fit: coverage rounds up more sensibly than down, and the additional premium is usually modest. See figuring out your coverage number for the full framework.
The choice should not come down to which round number feels right. Run the DIME formula (Debt plus Income replacement plus Mortgage plus Education, minus existing assets and coverage) and buy close to what it produces. If the math says $820,000, a $1 million policy is often the better fit: coverage rounds up more sensibly than down, and the monthly premium difference between $800k and $1 million is usually small.
Yes. Carriers typically offer coverage in increments of $50,000 or $100,000; there is no rule requiring a binary choice. A $750,000 policy is a reasonable middle point, and for many households it will match the coverage calculation more closely than either round number.
Many carriers require a full medical exam for coverage above $500,000, though requirements vary and some offer no-exam options at higher face amounts with different underwriting. Your agent can clarify what applies to the carrier and amount you are considering. For healthy applicants, completing the exam typically produces better pricing.
Can I have two policies instead of one large one? Yes. Owning multiple policies from different carriers is permitted and sometimes used to layer coverage. One common approach is a 30-year $500k policy for long-term obligations alongside a 20-year $500k policy for the highest-need years, with the shorter one expiring when children are independent.
Is a $1 million life insurance policy hard to qualify for? Not for healthy applicants. The underwriting process is the same as for smaller amounts, though a full exam is more commonly required at higher face amounts. The main factor is health, not the dollar amount.
The premium difference between $500,000 and $1,000,000 in term coverage is smaller than most people expect, typically $20 to $55 per month for applicants in their 30s and 40s. The right amount is what your coverage calculation produces. Use the life insurance coverage calculator to run your household's numbers, compare quotes at both amounts, and consider a licensed agent who can check pricing across multiple carriers for your profile. Nothing above is a substitute for an actual underwriting decision from a carrier.
