Calculating diminished value
A car that’s been in an accident is less valuable than it was before the accident. This is true even if repairs return it to working order. The difference between what the pre-accident car was worth, and its market value now is known as the vehicle’s diminished value.
Has your car been in an accident? Use this calculator to determine the diminished value of your vehicle.
Using the calculator
In order to calculate the diminished value of your vehicle, you will need to gather some information.
1. Pre-accident value of your vehicle
To determine the value of your vehicle, you can use websites like Kelly Blue Book and enter data like your vehicle’s make, model, mileage and location as all of these impact its cost.[1]
2. How much damage your car sustained
You will also need to provide an honest assessment of how much damage your car received during the accident. Was it structural or more cosmetic damage? How much of the vehicle did it impact? These will all affect your diminished value.
3. Your car’s mileage
This should be your car’s current mileage, not the mileage at the time of the accident.
Once you have this information, enter it in the calculator to determine your diminished value.
How diminished value is calculated
Diminished value is typically calculated by your insurance company if you are seeking a diminished value claim payout after an accident. It is calculated using the 17c formula which is as follows.
1. A 10% cap is applied to the car’s pre-loss value
So if your vehicle was worth $10,000 before the accident, the max its diminished value would be is $1,000 (10,000 X .10 = 1,000).
2. A damage multiplier is applied
Next, the damages are taken into account with a damage multiplier running from .00 to 1.00. This is how the level of damage translates to the multiplier. Obviously, the larger the damages, the larger percentage is deducted from the value of the vehicle.
3. Apply a mileage multiplier
Finally a mileage multiplier is added based on the total miles on your vehicle. Multiplier levels are increments of .20.
Diminished value calculation example
Luckily, we do the math for you, but here's an example of what our diminished value calculator does for you in seconds.
Let’s say the market value of your car according to Kelley Blue Book is $12,000. First, take 12,000 and multiply it by 10% to account for the 10% cap. 12,000 x .10 = 1,200. The new number we’re working with is $1,200. This is the maximum amount your insurer would pay out for a diminished value claim.
- The accident you were in caused moderate damage to the structure and panels of your car. Now take 1,200 and multiply it by the value for moderate damage. 1,200 x .50 = 600.
- There are 20,000 miles on your vehicle. By applying the appropriate mileage multiplier to the new number calculated in step 3, we have 600 x 0.80 = 480.
- The diminished value of your car is $480 based on these circumstances.
