Write Off Value Formula
The write off value calculator uses the relationship between current value, write-off rate, and write-off amount. You enter exactly two values, and the calculator solves for the third.
- WOV = write-off value or write-off amount
- CV = current value of the car or asset
- WOR = write-off rate as a percentage
To calculate the write-off rate, the formula is rearranged:
To calculate the current value, the formula is rearranged again:
- Find write-off amount: Enter the current value and write-off rate. The calculator multiplies the value by the rate as a decimal.
- Find write-off rate: Enter the current value and write-off amount. The calculator divides the amount by the current value, then converts it to a percentage.
- Find current value: Enter the write-off amount and write-off rate. The calculator divides the amount by the rate as a decimal.
Common Write-Off Rate Examples
These examples show how different write-off rates affect the amount written off from a car, equipment item, or other asset.
| Current Value | Write-Off Rate | Write-Off Amount |
|---|---|---|
| $5,000 | 10% | $500 |
| $10,000 | 25% | $2,500 |
| $20,000 | 40% | $8,000 |
| $30,000 | 75% | $22,500 |
How to Read the Write-Off Rate
| Write-Off Rate | Meaning |
|---|---|
| 0% | No value is written off. |
| 25% | One quarter of the current value is written off. |
| 50% | Half of the current value is written off. |
| 100% | The full current value is written off. |
Example Problems
Example 1: Calculate the write-off amount
You have an asset with a current value of $12,000 and a write-off rate of 30%.
The write-off amount is $3,600.
Example 2: Calculate the write-off rate
An asset has a current value of $8,000 and a write-off amount of $2,000.
The write-off rate is 25%.
FAQ
What does write-off value mean?
Write-off value is the amount of an asset’s current value that is being written off. For example, if a car is worth $10,000 and the write-off rate is 40%, the write-off value is $4,000.
Can the write-off rate be more than 100%?
No. In this calculator, the write-off rate must be between 0% and 100%. A 100% write-off means the full current value is written off.
Why do I need to enter exactly two values?
The formula has three related values: current value, write-off rate, and write-off amount. If you enter any two of them, the missing one can be calculated. If you enter only one value, there is not enough information. If you enter all three, there is nothing missing to solve.
