Your auto quote can show a comprehensive deductible and a collision deductible, with different amounts beside each. Before choosing a cheaper premium, make sure you know which number goes with which protection. The decision is easier when you compare a specific loss and an amount you could actually pay, instead of searching for one universally “best” deductible.
Start with the two coverage labels
The National Association of Insurance Commissioners' auto insurance overview describes collision as protection for damage to the insured vehicle from hitting a car or object. Comprehensive addresses non-collision events, such as theft, fire, or weather. These coverages often have deductibles, and a lender may require them on a financed or leased vehicle.
A deductible is the part of a covered claim that you pay. It does not create coverage for an event the policy excludes. Before comparing deductible options, confirm that the quote actually includes both coverages you intend to buy. For a broader starting point, see our auto insurance page.
Use two different scenarios
Consider a car damaged when it hits a fence. Collision is the coverage to ask the insurer about. Now consider the same parked car damaged by a falling branch. That is a different cause of loss; ask about comprehensive. The Florida Department of Financial Services' coverage overview includes falling objects among comprehensive examples.
These examples identify the coverage to discuss, not a promise that an individual claim will be paid. Your insurer still needs the facts and the policy terms. Do not describe a loss differently to fit the coverage you would prefer to use.
On a quote comparison sheet, give comprehensive and collision their own rows. For each, record whether coverage is included, the deductible, the premium shown if separately itemized, and any question you still need answered. A blank line is a question for the agent, not proof that the deductible is zero.
Work through the arithmetic without treating it as a claim estimate
Here is a simplified illustration only. Suppose an insurer has determined that a repair loss of $2,400 is covered and subject to a $500 deductible. Subtracting that deductible leaves $1,900. With a $1,000 deductible, the same simplified calculation leaves $1,400. Those are invented arithmetic examples, not repair quotes, premiums, or predictions of what an insurer owes.
Actual settlements can involve limits, valuation, exclusions, and other policy provisions. The California Department of Insurance's auto guide explains deductibles and vehicle-damage coverage. Its state-specific rules should not be assumed to apply in another state. Ask your insurer how the deductible works on the exact policy you are considering.
Compare the premium difference with your available cash
Request two otherwise equivalent options. Change only the deductible you want to evaluate, and ask the agent to identify any other differences. Compare the total price for the same term and payment basis. An installment amount alone is not enough information if the number of installments or initial payment also differs.
Then ask a practical household-budget question: could you pay the higher deductible when a covered loss occurs? Do not use an emergency fund figure you only hope to have later. If an option leaves you unable to arrange a necessary repair, its lower quoted premium may not fit your situation.
There is no savings percentage promised here. Record the actual difference between the two offers. If you divide the deductible increase by the annual premium difference to explore a rough trade-off, label that calculation carefully: it does not predict claims, future rates, or how long you will keep the car.
Check the details people tend to bundle together
- Glass: Ask whether the policy has a separate glass provision or deductible. Do not assume every state or endorsement handles it identically.
- Financing: Check the loan or lease requirements before requesting a deductible change.
- Transportation: Ask separately about rental reimbursement; a repair discussion should not leave you guessing about transportation benefits.
- Several vehicles: Identify the deductible for each car and coverage rather than reading one vehicle's line as the answer for all of them.
Texas' auto insurance shopping guide offers a useful model for asking about coverage, deductibles, and exclusions. Use it as a shopping aid; obtain answers for your own state's policy rather than importing another state's rules.
Ask for the comparison before making a change
Try this: “Please show me comprehensive and collision separately, with the deductible options and the total price for the same term. Tell me what else changes, and whether my lender's requirements affect those choices.” Keep the response with the offer you select.
If you also need an SR-22 filing, tell the agent at the start and review it as a separate requirement. Our SR-22 page is a starting point for that conversation. To discuss deductible options on an actual quote, contact The Car Insurance Guy. Coverage availability and claim decisions depend on the applicable policy and facts.
