What it means
Most households insure their home and their car, which are worth far less than the total earnings the household expects over a working lifetime. Disability-income insurance protects that earning stream, paying a monthly amount if the policyholder becomes unable to work because of sickness or accident.
Because the loss it covers is income rather than a repair bill, the benefit is quoted as a monthly figure rather than a lump sum. Three policy features do most of the work.
The replacement ratio sets what proportion of pre-disability earnings is paid, the elimination period sets how long the claimant must wait before benefits start, and the benefit period sets how long payments continue. Longer waiting periods and shorter benefit periods produce cheaper premiums, which is how cover is tailored to a budget.
The definition of disability is the single most important clause and the most frequently misunderstood. An "own occupation" policy pays if the insured cannot perform the duties of their specific job, while an "any occupation" policy pays only if they cannot perform any work they are reasonably suited to, which is a far harder test to satisfy.
Tax treatment follows who paid the premium. Where an employer pays and does not include the premium in the employee's taxable pay, benefits are generally taxable when received, whereas where the individual pays from after-tax income the benefits are usually received tax-free.
This is why a 60% replacement ratio on a personally funded policy can leave the claimant better off than a 70% employer-funded one. Business owners use variants of the same product for different purposes.
Key person disability cover pays the company rather than the individual, business overhead expense cover pays fixed running costs while an owner is unable to work, and disability buy-out cover funds the purchase of a disabled partner's stake.
In practice
Real-world examples.
Example
A self-employed physiotherapist with no employer sick pay buys an own occupation policy with a 30-day elimination period, accepting a higher premium because she has no salary continuation to fall back on. When a wrist injury stops her treating patients, the policy pays even though she could technically do office work.
Example
A law firm buys business overhead expense cover on each of its three partners. When one partner is off for eight months following surgery, the policy pays rent, staff salaries and practice insurance so the firm does not have to fund those costs from reduced billings.
Example
An employee at a large logistics company relies on a group policy paying 66% of salary with an any occupation definition after the first two years. His adviser recommends topping up with a small individual policy, because the group definition may stop paying once he is judged capable of any suitable work.
Formula
Calculation
Monthly benefit = pre-disability monthly earnings x replacement ratio, capped at the policy maximum
Total benefit paid = monthly benefit x (months disabled - elimination period in months)
A design consultant earns $120,000 a year, which is $120,000 / 12 = $10,000 per month. She buys an individual policy with a 60% replacement ratio, a 90-day elimination period, benefits payable to age 65, and an own occupation definition.
Monthly benefit = $10,000 x 0.60 = $6,000, which is below the policy's $8,000 monthly cap, so the full $6,000 applies. She pays a premium of $2,400 a year from after-tax income, so benefits would be received tax-free.
She suffers a spinal injury and is unable to work for 27 months. The first 90 days, or 3 months, fall in the elimination period and are unpaid, so benefits run for 27 - 3 = 24 months.
Total benefit received = $6,000 x 24 = $144,000, entirely tax-free. Over the ten years she had held the policy she had paid $2,400 x 10 = $24,000 in premiums, so the claim returned $144,000 / $24,000 = 6.0 times the total premiums paid.Case study
Seen in the real world.
Redhill Dental Partners is an invented practice used here purely as an illustrative example. Three dentists ran the business, and each assumed the group cover attached to their practice health scheme would look after them, without reading the definition of disability it used.
When one partner developed a tremor that ended her clinical career at 44, the group policy assessed her under an any occupation test and concluded she could work in dental practice management. Benefits were declined after the initial short-term period, and the practice discovered it also had no cover for her share of the fixed overheads or for buying out her equity.
Following this illustrative episode the partners restructured their arrangements: individual own occupation policies funded personally so benefits would be tax-free, business overhead expense cover for the practice, and a disability buy-out agreement funded by insurance rather than by future profits. The combined premium was a little over 2% of practice revenue, which the partners considered cheap relative to the alternative they had just lived through.
Watch out
Common mistakes.
- Assuming employer group cover is sufficient. Group policies frequently use an any occupation definition, cap benefits at a level well below a senior earner's income, and end when employment ends.
- Ignoring who pays the premium. Employer-funded benefits are usually taxable while personally funded ones usually are not, which materially changes the income actually received.
- Buying the shortest elimination period available. Waiting periods of 90 or 180 days cost far less, and a household with several months of savings is usually better off holding the cash and paying a lower premium.
Questions
People also ask.
Why is the definition of disability so important?
Because it determines whether a claim is judged against the insured person's actual occupation or against any work they could reasonably do, and the second test is much harder to meet.
What replacement ratio is typical?
Insurers commonly cap cover around 60% to 70% of pre-disability earnings, deliberately leaving a gap so there is a financial incentive to return to work.
Does disability-income insurance cover redundancy or job loss?
No, it responds only to inability to work caused by illness or injury, and unemployment is a separate and quite different risk.
