Quick Comparison Between IAD and ITP (Direct Answer)
IAD vs. ITP — A Simple Summary

Quick conclusion:
A ITP covers many more situations than IAD, although it costs a little more.
What is IAD (Total and Permanent Disability)?
IAD is the most restrictive (least comprehensive) coverage.
It only activates when the person:
- The person is left with a very high level of disability (usually above 80%, but it is difficult to specify an exact percentage)
- You become completely dependent on others
- Is unable to work in any profession
- Is unable to perform basic activities of daily living
In practice, IAD functions almost like a situation of dependency and is treated as an extreme case for insurance purposes.
Typical examples of IAD situations
- Vegetative state
- Quadriplegia
- Severe, disabling neurological diseases
- Severe brain injuries
- Permanent total disability
Because this is a more limited type of coverage, the insurance premium tends to be lower.
What is ITP (Total and Permanent Disability)?
A ITP It provides much more comprehensive coverage.
Enable when:
- Disability is typically ≥ 60% (depending on the company)
- The person is no longer able to practice their profession
- There is a significant loss of work capacity
This means that You don't have to rely on others.
All it takes is being unable to work, which results in a loss of income.
Case Studies: When to Use IAD vs. ITP
Case Study 1
A person suffers a stroke and is left with a 65% disability rating, forcing them to retire on disability.
Result:
- IAD → inactive
- ITP → active
ITP insurance would pay off your mortgage to the bank or pay the principal amount to the insured (if the policy is not linked to a mortgage).
Not the IAD.
Case Study 2
A person suffers a serious accident and becomes completely dependent on others.
Result:
- IAD → active
- ITP → active
Under an insurance policy covering IAD or ITP, it would be possible to file a claim under this policy.
Please note that coverage cannot be claimed for multiple policies at the same time: for example, once a claim is paid under ITP, it will not be paid under IAD as well.
Case Study 3
A person develops a degenerative disease that prevents them from continuing to work, but they retain their personal autonomy.
Result:
- IAD → inactive
- ITP → active
This is the most common scenario where the choice makes a difference.
Why do banks prefer ITP?
Today, most banks prefer or recommend ITP because:
- Reduces the risk of default
- Provides better protection for the customer
- Increases the likelihood that the insurance will pay out
Some institutions require:
- ITP 60%
- ITP 65%
This may directly affect whether your loan is approved.
According to the Bank of Portugal, life insurance must provide adequate protection against the risk of the borrower becoming disabled.
You can view the official recommendations at Bank of Portugal website.
How the choice between IAD and ITP Affects the Price of Insurance
On average:

But be careful:
Choosing IAD just to pay less could be a serious financial mistake.
The real risk is: to be disabled and for the insurance not to pay out.
Therefore, the choice should be based on protection, not just price.
