Deductible

Here’s a clear, practical, story-supported explanation of insurance deductibles, their purpose, and the three major types you listed.

1. What Is an Insurance Deductible?

A deductible is the amount of money you must pay out of your own pocket before the insurer starts paying for a covered loss.

Think of it as the first slice of the loss that you handle, and the insurer handles the rest.

Real Story Example

A small electronics shop in Addis Ababa suffers a fire causing 150,000 birr damage.
The policy has a 10,000 birr deductible.

• The shop pays: 10,000 birr

• Insurer pays: 140,000 birr

It’s like saying: “I’ll cover the first part of the damage; you (the insurer) cover the rest.”

2. Purpose of Deductibles

Deductibles exist for three main reasons:

1. Reduce Small, Frequent Claims

Insurers don’t want to handle tiny claims (like 500 birr broken glass).
A deductible filters out these claims.

2. Control Moral Hazard

If insurance covered 100%, people might be careless.
When you pay part of the loss, you’re more motivated to avoid risks.

3. Make Insurance Affordable

Sharing a part of the loss reduces the insurer’s total payouts → lowers the premium.

4. Encourage Loss Prevention

When a business knows it will pay the first portion, it invests more in safety (locks, alarms, fire extinguishers).

3. Types of DeductiblesA. Straight Deductible (Fixed Amount per Loss)

This is the most common type.

You pay a fixed amount every time a loss happens.

How It Works

If your deductible is 5,000 birr, and three different accidents happen during the year:

• Accident 1: you pay 5,000

• Accident 2: you pay 5,000

• Accident 3: you pay 5,000

The deductible applies each time.

Real Example

A car policy with a 2,000 birr straight deductible:

• Accident damage: 12,000 birr

• You pay 2,000 birr

• Insurer pays 10,000 birr

Interpretation

Straight deductible = “You always pay the first slice of each loss.”

B. Aggregate Deductible (Total for Whole Year)

Here, the deductible applies to the total losses in a year.

Once you pay the cumulative deductible, the insurer pays 100% of additional losses.

How It Works

Let the aggregate deductible be 20,000 birr.

• 1st loss: 8,000 – you pay 8,000 (total paid = 8,000)

• 2nd loss: 9,000 – you pay 9,000 (total paid = 17,000)

• 3rd loss: 10,000 – you pay only 3,000 to reach 20,000
  After that, the insurer pays everything.

Use Case

Common in:

• Health insurance

• Commercial liability policies

• Stop-loss insurance

Interpretation

Aggregate deductible = “You pay up to a yearly limit; after that, the insurer covers the rest.”

C. Franchise Deductible (Threshold Deductible)

This is different and a bit unusual.

If the loss is below the deductible → insurer pays nothing.
If the loss is above the deductible → insurer pays the FULL amount.

How It Works

Deductible: 10,000 birr

• Loss of 8,000 → You get 0

• Loss of 12,000 → Insurer pays entire 12,000

The deductible acts like a trigger, not a shared payment.

Real Example

Used often in marine insurance.

If cargo damage is below the franchise, insurer ignores it.
If it exceeds it, insurer pays all of the loss.

Interpretation

Franchise deductible = “If the loss crosses the threshold, insurer pays everything.”

Deductibles exist to control costs, prevent careless behavior, and keep premiums affordable.
The three big types help insurers shape how much risk you share.
