Cost example updated November 4, 2026
The full example, line by line
One crash, one set of inputs, so every line can be checked. The driver is at fault, the car is a $25,000 sedan with 50,000 miles on it, the damage is a low-speed rear-end collision, and the policy is full coverage with a $500 deductible, the most common deductible in published 2026 guides. No injuries are in this example. That is a property-damage-only crash.
- Repair bill: $4,700
- Rental car: $620 (10 days at $62 a day)
- Diminished value: $375
- Higher premiums: $4,725 ($1,575 a year for 3 years)
- Total: $10,420
Who pays which line is where the example gets honest. The insurer pays $4,200 of the repair, which is the $4,700 bill minus the $500 deductible. The driver pays the $500 deductible, the $620 rental, the $375 in lost value, and the $4,725 in higher premiums, which adds to $6,220. The two sides reconcile: $10,420 minus the insurer's $4,200 is the driver's $6,220. About 60 cents of every dollar in this example falls on the driver. One accounting note, stated so the total is not double counted: the $500 deductible sits inside the $4,700 repair line, not on top of it.
Formula
The all-in total is four lines: repair $4,700 plus rental $620 plus diminished value $375 plus higher premiums $4,725, which equals $10,420. The rental is 10 days at $62 a day, which is $620. The higher premiums are $1,575 a year for 3 years, which is $4,725. The split is the repair minus the deductible on one side and everything else on the other: the insurer pays $4,200 of the repair, which is the $4,700 bill minus the $500 deductible, and the driver pays the $500 deductible plus the $620 rental plus the $375 in lost value plus the $4,725 in higher premiums, which adds to $6,220. The two sides reconcile: $10,420 minus the insurer $4,200 is the driver $6,220.
The diminished value uses the 17c method in three steps: take 10 percent of the pre-accident value as a base loss, multiply by a damage multiplier, and multiply by a mileage multiplier. In this example, $25,000 times 10 percent is $2,500. Minor damage to structure and panels carries a 0.25 multiplier, which brings it to $625. A car with 40,000 to 59,999 miles carries a 0.60 mileage multiplier, which brings it to $375. The $500 deductible sits inside the $4,700 repair line, not on top of it.
The same math from opposite sides, for four repair sizes. The insurer column is the repair minus the $500 deductible. The surcharge column is three years at the Quadrant row for that damage size. A $1,500 repair: insurer pays $1,000, 3-year surcharge $4,230 on the under-$2,000 row at $1,410 a year. A $2,500 repair: insurer pays $2,000, 3-year surcharge $4,725 on the over-$2,000 row at $1,575 a year. A $4,700 repair: insurer pays $4,200, 3-year surcharge $4,725. An $8,000 repair: insurer pays $7,500, 3-year surcharge $4,725.
The repair bill: why $4,700
Nexar's 2026 cost analysis puts the average minor-accident repair at $4,700, citing Insurance Information Institute figures, and puts the rise since 2020 at 32 percent, driven by parts costs, labor rates, and driver-assist hardware. The component ranges behind that average, from the same analysis: a rear bumper cover runs $800 to $2,200, plus $400 to $900 for rear sensors; a front bumper with radar runs $1,400 to $4,000; a quarter panel runs $1,200 to $3,500; a hood runs $900 to $2,800.
Two cross-checks sit next to that figure. The Insurance Information Institute's own 2024 data puts the average collision claim at $5,489, but that average covers all collision claims, including severe crashes, so a minor-only average landing below it is the expected shape. A 2026 body-shop guide puts a complete auto body repair typically between $500 and $5,000. The $4,700 example sits inside that spread. One more data point: the Insurance Institute for Highway Safety staged 7 low-speed collisions between new cars, and the median cost to repair damage to both cars was $3,000. Sensor-heavy cars run higher than the average, because a front bumper with radar can reach $4,000 before calibration, and one published 2024 Tahoe rear-end example put driver-assist calibration alone at $680.
The deductible: $500, and how it splits the bill
$500 is the most common collision deductible in published 2026 guides (Insurify, updated November 2, 2026; MoneyGeek). Insurers typically offer $250, $500, $1,000, and $2,000. The deductible applies to collision coverage, which pays for damage to your own car in a crash. It does not apply to liability coverage, which pays for damage and injuries you cause to other people and their property.
On this example the split is simple: a $4,700 repair with a $500 deductible means the driver pays $500 and the insurer pays $4,200 for covered repairs. A financed or leased car usually carries a lender requirement for collision coverage, with the deductible commonly capped at $500 or $1,000. A higher deductible lowers the premium and raises the cash needed after a crash; a lower deductible does the reverse. The declarations page states the deductible on the policy.
The rental: 10 days at $62 a day
Industry guides converge on 7 to 14 days for a minor collision repair, with parts availability and shop workload moving the number. This example uses 10 days, inside that span. Hertz reported average revenue of $61.98 per rental day in the second quarter of 2026, and Avis Budget reported $68.29 company-wide in the same quarter. At $62 a day, rounded from the Hertz figure, 10 days is $620.
Rental reimbursement coverage, where a policy carries it, has daily and total limits set by the policy, so the example uses the full rental cost. A policy with reimbursement limits changes what the driver actually pays for those 10 days, and a policy without that coverage leaves the full $620 with the driver.
Diminished value: the $375 the car never gets back
A repaired car is worth less than an identical car with a clean history, and that gap is diminished value. Insurers commonly figure it with the 17c method, named for paragraph 17(c) of the proceedings that followed the Georgia case State Farm v. Mabry. The method has three steps: take 10 percent of the pre-accident value as a base loss, multiply by a damage multiplier from 0.00 to 1.00, and multiply by a mileage multiplier from 1.00 down to 0.00 at 100,000 miles.
This example, step by step: $25,000 times 10 percent is $2,500. Minor damage to structure and panels carries a 0.25 multiplier, which brings it to $625. A car with 40,000 to 59,999 miles carries a 0.60 mileage multiplier, which brings it to $375. That $375 is the diminished value in this example.
Three limits on that number, stated plainly. First, 17c is the insurer's method, and multiple published guides say it understates the market loss; comparable-sales appraisals usually support higher numbers. Second, no state requires insurers to use 17c, and Georgia's own Department of Insurance directed in December 2008 that no fixed formula, including 17c, may be the sole measure of diminished value. Third, at 100,000 miles or more the mileage multiplier is 0.00, so the formula returns $0 however severe the damage was. Diminished value is normally claimed against the at-fault driver's insurer, so in this at-fault example the $375 is value the driver absorbs, not a check that arrives. Collision coverage pays the repair, not the lost value.
The premiums: $1,575 a year for 3 years
Rate data compiled by Quadrant Information Services for CarInsurance.com in 2026, for a 40-year-old driver with a good record and full coverage, shows a base premium of $2,578 a year. After one at-fault accident, the same driver averages $3,988 for property damage under $2,000 (up $1,410, or 55 percent), $4,153 for property damage over $2,000 (up $1,575, or 61 percent), and $4,238 for bodily injury (up $1,660, or 64 percent). This example uses the over-$2,000 row, because the $4,700 repair sits above that line.
The Insurance Information Institute puts the surcharge at about three years, and most published guides put the window at three to five years. At three years, $1,575 a year is $4,725. For the general insurance picture, including how the same crash lands on a liability-only policy, see how much car insurance costs.
Rates vary by state, insurer, and record. A separate LendingTree study from January 2026, using a 30-year-old driver, found a 45 percent average increase, about $1,031 a year, with California at 70.7 percent in that study. Some insurers sell accident forgiveness that can remove a first surcharge; whether a policy carries it is on the declarations page.
The same math from opposite sides, for four repair sizes. The insurer column is the repair minus the $500 deductible. The surcharge column is three years at the Quadrant row for that damage size. No recommendation sits on either column; the reader's own deductible, state, and insurer move both.
- $1,500 repair: insurer pays $1,000; 3-year surcharge $4,230 (under-$2,000 row, $1,410 a year)
- $2,500 repair: insurer pays $2,000; 3-year surcharge $4,725 (over-$2,000 row, $1,575 a year)
- $4,700 repair: insurer pays $4,200; 3-year surcharge $4,725
- $8,000 repair: insurer pays $7,500; 3-year surcharge $4,725
What these numbers do not settle
Honest gaps, stated here rather than settled quietly. First, towing, storage, and report copies vary by place and are not in this example. Second, not-at-fault pricing differs from this at-fault example, and no full-coverage not-at-fault dollar figure is stated here; liability-only data moves less, but it is a different coverage. Third, rental reimbursement limits vary by policy, so the $620 assumes the full rental cost. Fourth, the $4,700 repair figure is a minor-accident average; sensor-heavy and luxury cars run higher. Fifth, rates vary by state and insurer, as the California figure above shows. Sixth, injuries are not in this example: the Insurance Information Institute's 2024 average bodily injury claim was $28,278, and an injury changes the picture entirely.

Definitions
Deductible. The part of a covered repair the driver pays first. With a $500 deductible, the most common choice in published 2026 guides, a $4,700 repair means the driver pays $500 and the insurer pays $4,200.
Collision coverage. Coverage that pays for damage to your own car in a crash. The deductible applies to collision coverage.
Liability coverage. Coverage that pays for damage and injuries you cause to other people and their property. The deductible does not apply to liability coverage.
Diminished value. The gap between a repaired car worth and an identical car with a clean history. In this example, $375.
17c method. The insurer method for diminished value, named for paragraph 17(c) of the proceedings that followed the Georgia case State Farm v. Mabry: 10 percent of the pre-accident value, times a damage multiplier from 0.00 to 1.00, times a mileage multiplier from 1.00 down to 0.00 at 100,000 miles.
Surcharge. The higher premium after an at-fault accident. In this example, $1,575 more a year for property damage over $2,000, a 61 percent rise, for about three years.
Rental reimbursement. Coverage that pays for a rental car while yours is repaired, with daily and total limits set by the policy. A policy without that coverage leaves the full $620 with the driver.
At-fault. The driver caused the crash. This example is at-fault throughout; not-at-fault pricing differs.
Property damage. Damage to cars and property, as opposed to bodily injury. This example is property damage only, with no injuries.
Questions people actually ask
How much does a fender-bender cost in total?
In this example, $10,420 all-in: a $4,700 repair, a $620 rental, $375 in diminished value, and $4,725 in higher premiums over three years. The driver carries $6,220 of it, and the insurer pays $4,200 of the repair. The $500 deductible sits inside the repair line, not on top of it.
What does the deductible actually pay?
The deductible is the part of a covered repair the driver pays first. With a $500 deductible, the most common choice in published 2026 guides, a $4,700 repair means the driver pays $500 and the insurer pays $4,200. The deductible applies to collision coverage for your own car, not to liability coverage.
How much does insurance go up after an at-fault accident?
For a 40-year-old driver with full coverage and a clean record, Quadrant Information Services data published by CarInsurance.com in 2026 shows $1,575 more a year for property damage over $2,000, a 61 percent rise, and $1,410 more a year for damage under $2,000, a 55 percent rise. The surcharge runs about three years, which is $4,725 in this example.
What is diminished value, and how is it figured?
Diminished value is the gap between a repaired car's worth and an identical car with a clean history. Insurers commonly use the 17c method: 10 percent of the pre-accident value, times a damage multiplier, times a mileage multiplier. In this example, $25,000 times 10 percent times 0.25 for minor structural damage times 0.60 for 40,000 to 59,999 miles is $375.
How long is a car in the shop after a minor collision?
Industry guides put a minor collision repair at 7 to 14 days. This example uses 10 days, inside that span. At $62 a day, the Hertz second quarter 2026 average, 10 days of rental is $620.
