Formula
The remaining value is a declining balance:
value = price × (1 − annual decline) ^ years
The percent is one you type. It is not a published resale table, and it is not a tax depreciation schedule.
Assumptions
- The same percent applies every year.
- Nothing is added for mileage, condition, or options.
- The result is rounded to the nearest cent.
Worked example
A $32,000 vehicle losing 15% a year is worth $14,198.57 after 5 years.
Input definitions
- Annual decline
- The percent of the remaining value lost each year.
- Value remaining
- What the formula leaves after the years, not a guaranteed resale price.
Limitations
This is an estimate, not a loan offer, a lease quote, or tax advice. A lender can add fees, and sales-tax rules differ by place. The currency control changes the symbol only.
Questions
Is 15% a rule?
No. It is the example. Cars do not lose value on one schedule, so the percent stays in the field.
Can I use this for tax?
No. Tax depreciation follows its own tables. This is a planning sketch of resale value.
