Should I Self-Insure My Car Instead of Buying Collision Coverage?

Answer a few honest questions and our Decision Guide will tell you whether to drop collision, keep it another year, or wait until your finances catch up.

For most drivers, self-insuring collision coverage makes sense once the car is paid off and its market value falls below roughly $7,500 to $10,000 — the industry shorthand is the '10% rule,' which says to drop collision when your annual premium for collision and comprehensive exceeds 10% of your car's value. Since a collision payout is capped at your car's actual cash value minus the deductible, a $4,000 car with a $1,000 deductible can only ever recover $3,000, which often won't pay back a few years of premiums. But the math on the car isn't the whole decision: you also need enough accessible savings to absorb a total loss without hardship (most guidance pegs this at $3,000 to $5,000 minimum), a realistic backup plan if you suddenly have no car, and — critically — no active loan or lease, since lenders almost always require collision as a condition of financing. Comprehensive coverage, which pays for theft, hail, flooding, and animal strikes, tends to be cheaper than collision and is often worth keeping even after you drop collision. The smart move for self-insurers isn't just canceling the coverage — it's redirecting that exact premium into a dedicated high-yield savings account so the self-insurance is actually funded, not hypothetical.
