GAP Insurance

GAP insurance (Guaranteed Asset Protection) covers the gap between your vehicle's actual cash value (ACV) and the amount you still owe on your auto loan or lease if your car is totaled or stolen. It protects you from being stuck with a loan balance for a vehicle you no longer have.

Quick Summary

GAP insurance (Guaranteed Asset Protection) covers the gap between your vehicle’s actual cash value (ACV) and the amount you still owe on your auto loan or lease if your car is totaled or stolen. Essential for new car buyers with loans or leases, it prevents you from owing money on a vehicle you no longer own. Use our Auto Insurance Calculator to see if GAP insurance is right for you.

What is GAP Insurance?

In plain English: Gap insurance covers the “gap” between what you owe on your car loan and what your car is actually worth if it gets totaled. New cars lose value fast — if you total a brand new car, your regular insurance pays what it’s worth (which might be less than you owe), and gap insurance covers the difference.

How GAP Insurance Works

When your car is totaled or stolen, your standard auto insurance pays out the ACV of the vehicle. If you owe more than this amount, GAP insurance covers the difference, including any deductibles. This ensures you don’t have to pay out of pocket for a loan on a lost vehicle.

Coverage Type What It Pays For Required?
Liability Damage and injuries you cause to others Yes (in most states)
Collision Damage to your car from crashes No (but lenders often require it)
Comprehensive Damage from theft, weather, vandalism No
Uninsured Motorist Damage from drivers without insurance Varies by state
PIP (Personal Injury Protection) Your medical bills after an accident Required in no-fault states

The “Gap” Problem

Vehicles depreciate rapidly, especially in the first few years. The gap typically occurs because:

  • Rapid depreciation: New cars lose 10-20% of their value in the first year
  • Loan terms: Long-term loans mean you’re underwater for longer
  • Down payment: Small or no down payment increases the gap
  • Negative equity: Rolling over previous loan balances

When GAP Insurance is Most Important

  • New Car Purchases — New vehicles depreciate the fastest in the first year.
  • Long Loan Terms — 60+ month loans mean you’re underwater longer.
  • Leased Vehicles — GAP is often required by lease agreements.
  • Small Down Payments — Less than 20% down increases your risk.

What GAP Insurance Covers

The amount still owed on your loan after your standard insurance pays the ACV.
