Decreasing Term Life Insurance: How It Works and Cost

Decreasing term life insurance is a term life policy whose death benefit drops on a fixed schedule over the life of the policy. The schedule is usually matched to a declining financial obligation like a mortgage amortization. Premiums are typically level for the full term length, not decreasing, so the per-dollar-of-coverage cost rises each year as the death benefit drops. Decreasing term is most commonly sold as "mortgage protection insurance" or "mortgage life insurance" through lender-affiliated agencies. Few major retail carriers (Banner, Protective, Pacific Life) offer decreasing term as a stand-alone retail product.

You select a starting death benefit and term length (typically 15, 20, 25, or 30 years matched to a mortgage). The death benefit decreases each year on a pre-set schedule that approximates the amortization of a fixed-rate mortgage of equal length. Sample: $300,000 30-year decreasing term might start at $300,000 in year 1, drop to $270,000 by year 5, $230,000 by year 10, $170,000 by year 15, $90,000 by year 20, and $25,000 by year 25 before reaching zero at the end of year 30. The premium stays flat at the rate calculated for the average expected death benefit across the entire term.

A healthy 35-year-old non-smoker can buy a $300,000 30-year decreasing term policy for roughly $25 to $35 a month, which is typically 10 to 20 percent cheaper than a $300,000 30-year level term policy from the same carrier ($30 to $42 a month). The savings are smaller than buyers expect because the level premium is calculated against the average death benefit over the full term (typically about 50 to 55 percent of the starting face amount), not the starting face amount. Most retail buyers find the savings too small to justify the loss of flexibility versus level term.

Rarely, for the typical retail buyer. The premium savings versus level term (typically 5 to 15 percent) are small relative to the loss of coverage flexibility. If your mortgage gets paid off slower than the schedule (extra refinance, missed extra payments), you have a coverage shortfall. If you take on a new obligation during the term (second mortgage, business loan, second child), the decreasing death benefit may be inadequate. Most financial planners recommend level term as the default choice with the same term length matched to the longest obligation, because the level death benefit provides a buffer for unexpected new obligations and the premium difference is small.

Level term has a constant death benefit for the full term length and a constant premium. Decreasing term has a death benefit that drops each year on a fixed schedule and a constant premium. Level term is more expensive (typically 5 to 15 percent more) but provides constant coverage. Decreasing term is cheaper but matches a specific declining obligation. Level term is the better default for primary income replacement (mortgage + children + business). Decreasing term can make sense as a supplement specifically for a mortgage if the buyer wants to minimize cost and the mortgage is the only obligation.

Mortgage protection insurance (sometimes called mortgage life insurance) is decreasing term life insurance sold by lender-affiliated agencies as a way to pay off the mortgage balance if the borrower dies during the loan term. The death benefit is paid directly to the mortgage lender, not to the borrower's family. Most financial planners discourage mortgage protection insurance because: (1) the death benefit is paid to the lender rather than the family who can decide whether to pay off the mortgage or invest the proceeds, (2) the buyer has no flexibility in beneficiary designation, and (3) retail level term life insurance for the same coverage is usually cheaper and more flexible.

Decreasing term is less commonly offered as a retail product than level term. Carriers with notable decreasing-term products: Banner Life, Protective, and Pacific Life offer decreasing term in some states, typically marketed for mortgage protection. AAA Life offers a decreasing-term product. Several small specialty carriers (typically lender-affiliated) market decreasing term aggressively but at premium rates that are sometimes 30 to 60 percent above retail level term. Always compare a decreasing-term quote against a level-term quote at the same face amount before deciding.

Some decreasing term products offer a limited conversion option, but the conversion provisions are typically less generous than the conversion options on level term policies. Banner Life and Protective both offer conversion on their decreasing-term products but with shorter conversion windows than level term. AAA Life decreasing term typically does not include a conversion option. Always read the conversion provisions before buying, especially if you may want to convert to permanent insurance later.

No. Like all term life insurance, decreasing term is pure protection with no cash value, no surrender value, and no investment component. The entire premium goes toward the death benefit and carrier expenses. If you stop paying the premium, the policy lapses after the grace period and there is no refund. Permanent policies (whole, universal, indexed universal, variable universal) accumulate cash value but cost significantly more per dollar of death benefit.

In almost every case, level term is the better choice. The premium difference is small (5 to 15 percent) and level term provides important flexibility: if you take on a second mortgage or refinance, the level death benefit still covers the larger obligation. If you pay off the mortgage early through extra payments or a refinance, the level term still provides death-benefit protection for other obligations like college funding or income replacement. The only scenario where decreasing term makes sense is when the mortgage is the only obligation and the buyer is very confident the mortgage will be paid off on schedule.
