Car ownership calculator
Car Depreciation Per Mile Calculator
Estimate how your entered vehicle value loss spreads across ownership miles.
Use this calculator
What your result means
This spreads entered value loss across ownership miles as an average; real-world depreciation is not necessarily linear.
Worked example
The figures below are illustrative editable assumptions.
- Total depreciation
- Purchase price − resale value
- Total miles
- Annual mileage × ownership years
The calculator uses the same method with your inputs.
Formula
Mileage sensitivity
| Annual miles | Depreciation per mile |
|---|---|
| Lower | Higher for the same value loss |
| Higher | Lower for the same value loss |
Using the result
Use like-for-like assumptions and update the inputs when your mileage, prices or agreement changes.
This estimate supports planning; it does not replace a quote, agreement or vehicle valuation.
Practical guidance
Compare the result alongside your own mileage and cashflow needs.
Check the underlying agreement or supplier terms before making a decision.
Assumptions and limitations
- A zero-mile input does not produce a per-mile value.
- Resale value is an entered estimate.
Helpful questions

Are example values current prices or quotes?
No. They are illustrative, editable values only.
Can I change the assumptions?
Yes. Use figures that reflect your vehicle, agreement or travel pattern.
Does the result predict the future?
No. Prices, efficiency, values and agreement terms can change.
What is excluded?
Read the assumptions before relying on the estimate for a decision. You can also use the Annual Car Mileage Calculator, Car Running Cost Calculator and Total Cost of Ownership Calculator for related planning inputs.
