Both pay out while you are alive, which is what distinguishes them from life insurance. Critical illness pays a single lump sum on diagnosis of a covered condition. Disability insurance replaces part of your income for as long as you cannot work. They solve different problems, and many people who need one need the other.
Critical illness insurance pays a one-time, tax-free lump sum if you are diagnosed with a condition the policy covers — commonly cancer, heart attack, stroke or Alzheimer’s disease. It pays regardless of whether you can still work, and it is not intended as income replacement. It is there for the costs the diagnosis creates: travel for treatment, home modifications, childcare, a spouse taking unpaid leave.
Disability insurance replaces part of your income when you cannot work because of illness or injury. It generally replaces between 60% and 85% of income, pays monthly rather than once, and continues for a defined period or until you can work again.
The trigger differs too. Critical illness turns on a diagnosis matching the policy definition. Disability turns on your inability to work, which the insurer assesses and can reassess.
If you can only have one and you rely on your income, disability insurance usually protects against the larger risk. Being unable to work for two years is financially worse for most households than a one-time lump sum would offset, and disability covers the far wider range of causes — including back injuries and mental health conditions, which no critical illness policy lists.
Critical illness earns its place when a diagnosis would create immediate costs that income replacement does not cover, or where you have no income to replace. It is also the more useful of the two for someone whose spouse earns and who would be the one receiving care.
If you are self-employed, the case for disability cover is stronger again, because there is no employer plan and no sick leave behind you.
Often partly, and it is worth finding out exactly before buying anything. Group disability plans are common, but three things catch people out:
Disability policies pay after a waiting period — the time you must be unable to work before benefits begin. A longer waiting period lowers the premium, and is reasonable if you have savings or short-term coverage to bridge it.
Critical illness policies typically have a survival period instead: you must survive a set number of days after diagnosis for the benefit to be paid.
Critical illness policies pay only for the conditions they list, defined in specific medical terms. A diagnosis that a reasonable person would call serious may not match the policy definition, and early-stage cancers are frequently covered at a reduced amount or excluded. The list and the definitions matter more than the number of conditions advertised.
Disability policies exclude pre-existing conditions for a period, and assess whether you meet their definition of disabled rather than taking your doctor’s word alone.
Both are worth reading for exclusions before price. A cheaper policy that excludes the thing most likely to happen to you is not cheaper.
