Insurance Deductible Calculator

A deductible (franquia) is the share of a loss you carry yourself, but it is not always subtracted. Enter the loss and what your policy says to see what the insurer pays and what comes out of your pocket.

The insurer pays
€750.00
You bear
€250.00
Deductible applied
€250.00
% of the loss you bear
25.0%

Video: how to use the calculator

1

First: what the deductible is based on

A policy can express the deductible as a euro amount, as a percentage of the sum insured (common in home multirriscos cover) or as a percentage of the loss (common in own-damage motor cover). The last two need arithmetic, and that is where most estimates go wrong.

2

Then: the contractual minimum and maximum

Many policies read "10 % subject to a minimum of 250 EUR". The minimum overrides the percentage whenever the percentage falls below it; a maximum, where one exists, caps the deductible. The calculator shows the figure before and after those limits.

3

The step that decides everything: deductible or threshold

A deductible proper is subtracted from the payout. A threshold deductible (also called simple) is only a floor: below it the insurer pays nothing, at or above it the insurer pays the whole loss. Confusing the two is the costliest mistake here.

4

Finally: the sum insured is the ceiling

The insurer never pays more than the sum insured, however large the loss. When that bites, the problem is no longer the deductible but under-insurance: the sum you contracted sits below what the property is actually worth.

Worked example

A 1 000 EUR loss with a 250 EUR deductible. If it is a deductible proper, the insurer pays 750 EUR and you carry 250 EUR, which is 25 % of the loss. If the same figure is a threshold deductible, the 1 000 EUR loss clears the 250 EUR floor, so the insurer pays the full 1 000 EUR and you carry nothing. The policy is identical in every other respect: one word changes, and 250 EUR changes with it.

Frequently asked questions

What is an insurance deductible in Portugal?
It is the share of a loss borne by the insured party, on the terms set in the policy. Article 49(3) of the Insurance Contract Act expressly lets the parties set deductibles and indemnity tiers that condition what the insurer pays.
Is the deductible always subtracted from the payout?
No. Only a deductible proper is subtracted. A threshold deductible works as a floor: below it the insurer pays nothing, and at or above it the insurer pays the loss in full. Check which of the two your policy contracted.
What does "10 % subject to a minimum of 250 EUR" mean?
The deductible is 10 % of the figure named in the policy, but never less than 250 EUR. On an 1 800 EUR loss, 10 % would be 180 EUR, below the minimum, so the deductible applied is 250 EUR.
Is there a legal maximum deductible?
There is no general statutory figure. The law lets the parties set it, so the amount sits in the contract. Some compulsory lines have their own rules about what can be raised against an injured third party, which is a different question from the one between you and your insurer.
Is a higher deductible worth it?
A higher deductible lowers the premium and raises what you pay on every claim. The trade depends on how often you expect to claim and how much you can absorb at once. This calculator shows the second side of that trade, claim by claim.
