The Gap Between Your Payout and Your Loan

If your car is written off or stolen, your insurer pays out its market or retail value — not what you owe the bank. Early in a finance agreement, a car often depreciates faster than the loan reduces, so the payout can fall short of settling your finance. That shortfall is money you'd still owe on a car you no longer have, and it's exactly what gap cover is designed to bridge.

Why the gap appears

A new car can lose 20% or more of its value the moment it leaves the dealership, while your loan balance barely moves in the first year — especially with a small deposit or a balloon payment inflating the balance. The result is negative equity: you owe more than the car is worth, and a write-off leaves you with the difference.

When gap cover is worth it

If this calculator shows a meaningful shortfall, gap cover (a low monthly premium) can save you from a large unexpected debt. The exposure is usually largest in the first couple of years and on deals with little deposit or a balloon. Once your balance drops below the car's value, the gap closes and the need falls away.

Frequently Asked Questions

What is gap cover on a car?

It's short-term insurance that pays the difference between what your normal car insurer pays out if your car is written off (its retail value) and what you still owe on finance. Without it, that shortfall is a debt you'd carry on a car you no longer have.

Do I need gap cover?

It's most valuable when you owe more than your car is worth — common early in a finance term, with a small deposit, or with a balloon payment. If your finance balance is already below the car's value, the gap has closed and you may not need it.

Why doesn't normal car insurance cover this?

Standard comprehensive insurance pays out the car's market or retail value, which reflects depreciation — not your outstanding loan. The two figures differ, and gap cover specifically bridges that difference.
