Cost-of-Living Rider

A cost-of-living rider is an optional provision added to an insurance policy, for an additional premium, under which a stated benefit increases over time rather than staying fixed at the amount bought. On disability income coverage it is the provision that raises the monthly benefit during a long claim, so that a benefit set years earlier still buys something close to what it was meant to buy. The label is market vocabulary rather than a regulated term: neither NAIC's Glossary of Insurance Terms nor the California Department of Insurance's glossary defines it, though both define a rider itself as an amendment to the policy. Because the label is unstandardized, contracts using it differ on the two things that matter, which are what triggers the increases and what limits them. It is worth separating from two neighbors that share vocabulary: the Social Security cost-of-living adjustment, which is a statutory increase to a public benefit, and the future increase option, which is a right to buy additional coverage later rather than to have existing coverage grow.

What NAIC actually says about it, on the product where it matters most. In its consumer guidance on disability insurance, NAIC lists inflation protection among the terms a buyer should compare: "Not all policies will take inflation into consideration. A cost-of-living adjustment (COLA) may be an option for an additional premium. Also, because your benefit payment will not increase automatically as your income rises, it may be possible to purchase additional coverage to keep up with raises or promotions." That single passage separates the two ideas cleanly. Indexing what you already hold is one provision; buying more of it as your income grows is another. A contract can offer either, both, or neither, and the words on the declarations page do not reliably tell you which.

The increases are governed by four contract terms, none of them set by regulation. What index, if any, drives the increase, and whether the contract instead uses a flat annual percentage. Whether increases compound or are simple. Whether there is a cap on the annual increase, on the cumulative increase, or on both. And when increases start, which on disability income coverage is usually after the claim has run for some period rather than from the first payment. Two riders described identically can differ by a large multiple over a twenty-year claim on those four points alone.

Long-term care is the one product where inflation protection is not merely a rider, and the difference is legal rather than commercial. NAIC's Long-Term Care Insurance Model Regulation provides at section 13A that "no insurer may offer a long-term care insurance policy unless the insurer also offers" the option of a policy with inflation protection no less favorable than one of three named forms: annual increases compounded "at a rate not less than five percent (5%)"; a guaranteed right to increase benefit levels periodically without evidence of insurability; or coverage of a specified percentage of actual charges with no maximum indemnity. Section 13G requires a signed rejection if the buyer declines. So on a long-term care policy this is an offer the insurer must make and the buyer must actively refuse, rather than an extra a buyer may add. The long-term care insurance page covers what those forms are worth and how to choose between them.

That same regulation makes explicit the point a disability buyer has to check in their own contract. Section 13E provides that inflation protection increases "shall continue without regard to an insured's age, claim status or claim history, or the length of time the person has been insured under the policy". Where regulation prescribes inflation protection, in other words, it says in terms that the increases do not stop when a claim starts. On products where no such rule applies, whether the benefit keeps rising during a claim is the contract's answer to give, and it is the single sentence most worth finding.

One related protection exists in regulation and is easy to confuse with this. The NAIC accident and sickness minimum standards regulation provides at section 7G(3) that "no reduction in benefits shall be put into effect because of an increase in Social Security or similar benefits during a benefit period". That stops a public cost-of-living increase being used to shrink a private benefit through an offset clause. It does not make the private benefit grow. The two are opposite sides of the same worry and only one of them is regulated.

On a disability income policy the sequence is usually this. The claim is approved, the elimination period runs, and the base monthly benefit is paid. After the claim has continued for the period the rider specifies, commonly a year, the benefit is recalculated by applying the rider's rate or index, and it is recalculated again on each anniversary the claim survives. When the claim ends the benefit generally reverts to the base amount for any future claim, unless the contract says otherwise, and any cap in the rider limits how far the increases can run.

A hypothetical example of what the rider is worth on a long claim. Take a $6,000 monthly benefit and a rider that increases it by 3% compounded on each anniversary of the claim. After ten years the benefit is $6,000 multiplied by 1.03 to the tenth power, which is $6,000 multiplied by 1.343916, or $8,063 a month. Now look at the same claim without the rider. The benefit is still $6,000, and if general prices have also risen 3% a year, that $6,000 buys what $4,465 bought at the start ($6,000 divided by 1.343916). The rider has not made the claimant better off than they were on day one; it has stopped them becoming roughly a quarter worse off, since $1,535 of the original $6,000 of purchasing power is what the ten years took. The 3% here is this hypothetical rider's rate, not a market standard.

The way to size the decision is to compare that erosion against the benefit period. A policy that can pay for two years is exposed to very little inflation risk, so the rider adds little. A policy that can pay from age 40 to age 65 is exposed to twenty-five years of it, and there the rider is arguably the difference between the coverage doing its job and doing part of it. The extra premium is charged from the day the policy is bought, on a benefit that may never be claimed, which is the cost side of that comparison.

Pros

• It protects the exact scenario long-duration coverage exists for, a claim lasting decades, where a fixed benefit loses most of its value.
• Increases are contractual rather than discretionary, so they do not depend on the insurer's later goodwill.
• On long-term care coverage the equivalent protection is something the insurer must offer and the buyer must sign to decline, which forces the decision into the open.
• Where the rider is bought at issue, the increases are typically not subject to further health underwriting, unlike buying a larger benefit later.

Cons

• The extra premium is paid every year from purchase, on a claim that may never happen.
• The label is not standardized, so two riders described the same way can index at very different rates, compound differently, or cap out early.
• Increases often begin only after the claim has run for a stated period, so the first year of a claim is usually unindexed.
• A simple rather than compound increase falls a long way behind on a claim lasting more than a few years, and the contract does not always make which one it is obvious.
• On a short benefit period the rider buys little, because there is not enough time for inflation to do much damage.
