What is a Car Insurance Deductible?
A car insurance **deductible** is the specified amount of money that the insured must pay out-of-pocket before an insurance company will pay a claim. For example, if your repair bill is $4,000 and your deductible is $500, you pay the first $500 and your insurer covers the remaining $3,500.
Deductibles are a key factor in determining your **premium** (the regular cost of your insurance). Generally, choosing a higher deductible means you accept more financial risk for yourself, and in return, the insurance company will charge you a lower premium. Conversely, a lower deductible leads to a higher annual premium. It is a critical component of risk management and personal budgeting.
How to Analyze a Deductible Change (Example)
- Analyze the Annual Savings
If your premium is \$1,500 and a deductible increase saves you 10%, your annual savings are \$150. This is the amount you save every year, regardless of accidents.
- Determine the Max Out-of-Pocket Cost
If your proposed deductible is \$1,000, that is the maximum amount you will pay for a covered repair. If the repair costs \$3,000, you pay \$1,000. If the repair only costs \$500, you pay the full \$500, as it’s less than the deductible.
- Compare the Break-Even Point
The **break-even point** is the amount of time it takes for your annual premium savings to cover the increase in your deductible. In this example, if your deductible increases from \$500 to \$1,000 (\$500 change) and you save \$150 annually, it takes $3.33$ years (\$500 / \$150) to break even.
Frequently Asked Questions (FAQ)
Common deductibles are \$250, \$500, and \$1,000. Many people choose \$500 as a standard balance between monthly cost and risk.
Does my deductible apply to all claims?The deductible typically applies to collision and comprehensive coverage, which cover damage to your own car. It usually does not apply to liability claims, which cover damage to others.
How often should I review my deductible?You should review it annually, especially as your car ages or your financial situation changes. A lower-value car may warrant a higher deductible since the cost of collision coverage may not be worth the premium.
