Decreasing Term Life Insurance

Decreasing term life insurance is term coverage under which the death benefit reduces over the policy period on a schedule fixed in the contract, while the premium remains level. It exists for a need that falls predictably with time, and the only common household need shaped that way is an amortizing debt: as a mortgage or an installment loan is paid down, the amount a survivor would need in order to clear it falls too.

Like level term, the name is what NAIC's Life Insurance Disclosure Model Regulation calls a "generic name," defined at section 4.C as "a short title that is descriptive of the premium and benefit patterns of a policy or a rider." No insurance body defines decreasing term substantively; the two words simply describe the pattern, and the pattern is one level element and one declining one. It is worth naming the pairing explicitly, because "decreasing term" is routinely read as though the premium were the thing decreasing, which would be a different and much rarer product.

The schedule is in the policy, not in the loan, and that gap is the honest objection to the design. A decreasing term contract states how the death benefit falls: commonly in equal annual steps to zero, sometimes on a schedule built to approximate a mortgage amortized at an assumed interest rate. Either way the schedule is fixed when the policy is issued and does not adjust afterwards. An amortizing loan behaves differently. In the early years most of each payment is interest, so the balance falls slowly and then accelerates. A benefit that steps down evenly therefore sits below the balance it was bought to cover for virtually the whole term, not merely at the start. The two lines meet only at the beginning and the end; in between, the amortizing balance curves above the straight line the benefit follows, so the shortfall opens immediately, widens through most of the period, and only closes in the final years. Where the schedule was built around an assumed rate, refinancing, recasting, taking a payment holiday, or simply having borrowed at a different rate all reopen the same gap.

The other half of the mismatch is what the money is for. A mortgage-shaped policy answers a mortgage-shaped question, and a household that loses an earner does not only lose the ability to pay the mortgage. Income replacement, childcare, and the costs of the years afterwards do not shrink on the loan's schedule, and a policy sized to the debt alone covers only one of them. That is why sizing is a separate exercise from choosing a benefit pattern, and why it belongs with the general needs material rather than here.

Where the pattern actually shows up. Two named products are built on it and each has its own page. Mortgage protection insurance is sold to a homeowner and is usually decreasing term with the schedule tied to the loan. Credit life insurance is sold in connection with a specific credit transaction, is frequently written so the creditor is the beneficiary, and is regulated separately. NAIC's disclosure model, the source of the policy summary and buyer's guide a purchaser normally receives, expressly does not apply to credit life insurance at all, which means the comparison document available on an ordinary individual policy may not be available there.

How to price the trade. Against a level term policy of the same starting face amount and term, decreasing term is cheaper, because the insurer's average exposure is lower. The question is whether it is cheaper by enough. Level term is already inexpensive at younger ages, and the incremental cost of holding the full amount for the whole period is frequently modest against the certainty of never being short. The comparison is easy to run because both quotes are stated in dollars per month for a stated face amount, and there is nothing in either contract that makes them hard to line up.

The applicant chooses a starting face amount and a term, and is underwritten as for any term policy. The contract sets out the death benefit for each policy year, usually as a table. The premium is level and does not change as the benefit falls. If the insured dies, the beneficiary receives whatever amount the schedule shows for that policy year, and the policy ends. If the insured survives the term, the coverage ends with nothing paid, the same as any other term policy.

A hypothetical, to show the divergence. Suppose a borrower takes a $300,000 mortgage over thirty years at a fixed 6 percent, giving a principal and interest payment of about $1,798.65 a month, and buys a decreasing term policy starting at $300,000 and stepping down in equal annual amounts to zero over the same thirty years. Ten years in, the policy's schedule has taken the death benefit to twenty thirtieths of the original, which is $200,000. The mortgage balance at that point is roughly $251,000, because the early payments were mostly interest. The survivor is about $51,000 short of clearing the loan the policy was bought to clear. Nor does the gap close as the term runs on: at twenty years the schedule has taken the benefit to $100,000 while the balance is still roughly $162,000, a shortfall of about $62,000. The loan terms are invented for the arithmetic, and a policy whose schedule is built around an assumed mortgage rate would track more closely at that rate and less closely at any other.

The practical follow-through is to compare the policy's own benefit table against a current amortization schedule for the actual loan, year by year, rather than assuming the two were designed to match. Where they do not, the fix is usually a modest amount of level term alongside rather than a different mortgage policy.

Pros

• It costs less than level term of the same starting face amount, because the insurer's average exposure over the period is lower.
• The premium is level and the contract needs no attention once issued.
• For a need that genuinely shrinks on a known schedule, it avoids paying for coverage that is no longer required.
• Underwriting is the same as for any term policy, so a healthy applicant is priced on their own health.

Cons

• The benefit falls on the contract's schedule, not on the loan's, and an evenly declining benefit sits below an amortizing balance for virtually the whole term rather than only at the start.
• Refinancing, recasting or borrowing at a different rate widens that gap, and nothing in the policy adjusts.
• A death benefit sized to a mortgage covers the mortgage and nothing else, while the household's other needs do not shrink on the same schedule.
• Where the beneficiary is the creditor rather than the family, as in some credit life arrangements, the survivor never controls the money.
• The saving against level term is often smaller than buyers expect, so the coverage given up can be poor value.
