In Illinois, the total loss threshold is 70%: your insurer will declare the vehicle a total loss when the cost of repairs plus the vehicle’s salvage value equals or exceeds 70% of its actual cash value the moment before the accident. That figure comes from the Illinois Department of Insurance’s claim practices rule, and it is lower than the cutoff in many other states, which means Illinois cars get totaled on damage that might be repaired elsewhere.1Illinois General Assembly. 50 Ill. Admin. Code 919.80 – Required Claim Practices
What the 70% Rule Actually Measures
The formula has three inputs: estimated repair cost, salvage value, and pre-accident actual cash value (ACV). Add the first two together and compare the total to 70% of the third. If repair cost plus salvage meets or exceeds that number, the insurer will not authorize repairs. It settles the claim as a total loss.
A quick illustration. If your car was worth $20,000 immediately before the crash, the 70% line sits at $14,000. Once repair estimates and salvage value together climb to $14,000, the vehicle is totaled, even if the sheet metal damage looks like something a body shop could fix. Because salvage value is part of the equation, cars with strong parts markets cross the threshold faster than owners expect.
Illinois’s cutoff is stricter than the 75% or 100% thresholds used in some other states. If you’ve dealt with a total loss elsewhere, do not assume the same damage would get you repairs here.
A Separate 50% Trigger When There’s a Lienholder
The 70% rule is the insurer’s test. There is a second, independent trigger in the Illinois Vehicle Code. When a vehicle is damaged beyond 50% of its fair market value and a lienholder exists, the lienholder must apply for a salvage certificate, regardless of whether the insurer has formally called the car a total loss.2Illinois General Assembly. 625 ILCS 5/3-117.1 – Salvage Certificates So if your loan is still open and the damage crosses that 50% mark, the vehicle can end up in salvage status through the title system even if the insurer’s math falls short.
How Insurers Calculate Actual Cash Value
ACV is what your vehicle was worth on the open market immediately before the accident. Not what you paid, not what you owe. Insurers typically pull comparable-sales data from valuation services like CCC Intelligent Solutions, Mitchell, or Audatex, using recent transactions on vehicles of the same year, make, model, trim, mileage, and condition in your area.
Adjusters then adjust up or down for your specific vehicle. Low mileage, recent maintenance, new tires, and aftermarket upgrades push the number up. Pre-existing damage, excessive wear, missing parts, and rust pull it down. Under Illinois Department of Insurance guidance, there is no cap on deductions for prior unrepaired damage, but the combined deductions for general wear and tear, missing parts, and rust cannot exceed $500. Every deduction must be itemized with a specific dollar amount.3Illinois Department of Insurance. Total Loss Auto Claims with Your Insurance Company
Salvage value, the other input to the 70% test, reflects what the damaged vehicle would fetch at auction or from a salvage yard. It matters twice: it feeds the threshold calculation, and it comes off your payout if you’re allowed to keep the vehicle.
What the Settlement Has To Cover
Once the car is declared a total loss, the insurer has three options: pay the ACV in cash, repair the vehicle, or replace it with a comparable vehicle. Cash settlements are the norm. If the insurer chooses to replace, the replacement must be a comparable make and model in equal or better condition, and any replacement less than three years old must include a warranty.3Illinois Department of Insurance. Total Loss Auto Claims with Your Insurance Company
Beyond the vehicle’s ACV, Illinois law requires the insurer to reimburse you for applicable sales tax (technically “use or occupation taxes”) and title and transfer fees on a replacement. The reimbursement is capped at the tax amount that would apply based on the totaled vehicle’s value, and only covers taxes and fees you actually pay. The insurer can reimburse you after purchase or pay those amounts directly at settlement.4FindLaw. Illinois Code 215 ILCS 5/154.9
If you take a cash settlement and then find a substantially similar vehicle that costs more than what you were paid, the Illinois Department of Insurance notes you can bring that back to the insurer for possible adjustment.3Illinois Department of Insurance.

Whether You Can Keep the Vehicle
This is where Illinois surprises people. Unlike many states, Illinois restricts your right to keep a totaled car as an anti-theft measure. Under the Illinois Vehicle Code, you generally cannot retain the salvage once your insurer has declared a total loss. There are two exceptions:3Illinois Department of Insurance. Total Loss Auto Claims with Your Insurance Company
- The damage is exclusively from hail and does not affect the vehicle’s operational safety.
- The vehicle is nine model years old or older.
If you qualify under either exception and choose to keep the car, the insurer deducts the salvage value from your settlement. You receive a salvage certificate rather than a clean title, and the vehicle cannot legally be driven until it is repaired and re-titled. For everything else, the insurer takes the salvage and your settlement reflects the full ACV without a salvage deduction.
Salvage Certificates and Rebuilt Titles
A total loss declaration replaces the clean title with a salvage certificate. That certificate marks the vehicle as significantly damaged and not road-legal in its current condition. The salvage certificate fee in Illinois is $20.2Illinois General Assembly. 625 ILCS 5/3-117.1 – Salvage Certificates
A vehicle carrying a salvage certificate cannot be registered or driven on public roads. To get back on the road, the owner has to repair the vehicle and then apply for a rebuilt title. That process requires:
- Surrendering the original salvage certificate with the new title application.
- Completing an affirmation form listing every used essential part (identified by VIN and source) and every new part (with bills of sale or invoices).5Cornell Law Institute. Ill. Admin. Code tit. 92, 1020.80 – Inspection of Rebuilt Vehicles
- Passing a vehicle safety inspection under the Illinois Vehicle Equipment Law. The Secretary of State’s office conducts or authorizes the inspection.6Legal Information Institute. Ill. Admin. Code tit. 92, 1010.110 – Salvage Certificate – Additional Information Required
- Filing a completed application for a rebuilt vehicle title through the Secretary of State’s office.
A rebuilt title permanently marks the vehicle’s history. Any future buyer sees that the car was once totaled, and resale value typically drops by 20% to 40% depending on the severity of the original damage and the quality of the repairs.
Disputing the Insurer’s Valuation
If the settlement offer looks low, work the valuation report line by line. Are the comparable vehicles genuinely similar in mileage, condition, and options? Were your upgrades, recent maintenance, and specific trim accounted for? Adjusters sometimes miss options or pull comparables from distant markets with different pricing.
Gather your own evidence. Local dealer listings, recent sales of comparable vehicles nearby, maintenance records, and receipts for tires or parts all support a higher number. An independent appraisal from a qualified appraiser can carry real weight in negotiations when it draws on local market data.
Many auto policies contain an appraisal clause for exactly this dispute. Under a typical clause, either party makes a written demand, each side picks an appraiser, and the appraisers try to agree on value. If they cannot, they select an umpire whose decision is binding. You pay your own appraiser and split the umpire’s cost. Illinois does not currently require all auto policies to include an appraisal clause, so read your contract to see what process applies.
If negotiation and any appraisal process fail, you can file a complaint with the Illinois Department of Insurance, which reviews whether the insurer followed the claim practices rule.
Deadlines That Can Sink the Claim
Most Illinois auto policies require a sworn proof of loss within 91 days after the loss. The document states the date and cause of the loss and the extent of damage. File it promptly, even while settlement talks continue.3Illinois Department of Insurance. Total Loss Auto Claims with Your Insurance Company
If your policy sets a time limit for suing your insurer, that clock is paused from the date you file the proof of loss until the insurer denies all or part of the claim.7Illinois General Assembly. 215 ILCS 5/143.1 – Periods of Limitation Tolled The tolling only runs while a proof of loss is on file. Separately, if another driver caused the accident and you’re weighing a claim against that driver, Illinois generally allows two years from the accident date to sue for injuries or property damage.
