rate(%)
Annual depreciation: Annual depreciation measured in %, entered as a known value.
years(years)
Years: Years measured in years, entered as a known value.

Formula Notes

  • Use consistent units for values that are multiplied, divided, or compared.
  • Results may be rounded for readability, while the calculator keeps greater precision internally.
  • Real-world measurements and assumptions can introduce small differences from the calculated estimate.

Common uses

  • Estimate resale value
  • Compare ownership cost
  • Plan purchases

Assumptions

What this calculation assumes

  • Vehicle estimates depend on fuel type, driving conditions, maintenance, tire condition, and local prices.
  • Performance calculations assume the inputs describe the same vehicle setup.
  • Inputs are assumed to describe the same scenario and use compatible units.
  • Results may be rounded for readability.

Avoid mistakes

Quick checks before you rely on the result

  • Mixing MPG US, MPG UK, km/L, and L/100km.
  • Ignoring vehicle weight, drivetrain loss, or real driving conditions.
  • Mixing units, periods, currencies, or measurement systems without converting first.
  • Rounding intermediate values too early.

Step-by-Step Explanation

Follow the reasoning, not only the final number.

  1. 1

    Set up the calculation

    Enter the known values in the calculator fields.

    Starting with clearly defined values and units prevents the most common calculation errors.

  2. 2

    Work through step 2

    Keep the units consistent with the labels shown beside each input.

    This step transforms the known values into the form required by the formula.

  3. 3

    Work through step 3

    Apply the formula: Future value = purchase price x (1 - depreciation rate)^years.

    This step transforms the known values into the form required by the formula.

  4. 4

    Interpret the result

    Review the primary result and supporting values.

    Compare the result with your real-world goal, such as estimate resale value.

Worked example

Practical car depreciation calculator example

Known values

  • Purchase price: 35,000 $
  • Annual depreciation: 15 %
  • Years: 5 years

Calculation

  1. 1. Start with the known values shown for this car depreciation calculator scenario.
  2. 2. Substitute those values into Future value = purchase price x (1 - depreciation rate)^years.
  3. 3. Evaluate the expression and keep the requested unit and rounding.

Result and meaning

Estimated value: $15,529.69; Depreciation: $19,470.31
