Calculating your depreciation percentage is straightforward once you know the Vehicle Depreciation Percentage formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Vehicle Depreciation Percentage Calculator.

What is Vehicle Depreciation Percentage?

The Vehicle Depreciation Percentage calculation tells you your depreciation percentage from a few simple inputs. The figure you are solving for here is the depreciation percentage, expressed in percent.

The Vehicle Depreciation Percentage formula

The core formula is:

Depreciation percentage = (Purchase price - Current value) ÷ Purchase price × 100

Here is what each input means:

  • Purchase price — a money amount. Example: ₹10,00,000.
  • Current value — a money amount. Example: ₹6,00,000.

How to calculate it step by step

  • Write down the purchase price (for example, ₹10,00,000).
  • Write down the current value (for example, ₹6,00,000).
  • Apply the formula above to get your depreciation percentage.
  • Double-check the result with the Vehicle Depreciation Percentage Calculator.

Worked examples

Example 1

Input / OutputValue
Purchase price₹10,00,000
Current value₹6,00,000
Depreciation percentage40.00%
Value lost₹4,00,000.00

With purchase price of ₹10,00,000 and current value of ₹6,00,000, the depreciation percentage works out to 40.00%.

Example 2

With purchase price of ₹20,00,000 and current value of ₹6,00,000, the depreciation percentage works out to 70.00%.

ResultValue
Depreciation percentage70.00%
Value lost₹14,00,000.00

Example 3

With purchase price of ₹5,00,000 and current value of ₹6,00,000, the depreciation percentage works out to -20.00%.

ResultValue
Depreciation percentage-20.00%
Value lost-₹1,00,000.00

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.

Prefer not to do the maths by hand? — the Vehicle Depreciation Percentage Calculator does it instantly, for free, with the formula and a worked example built in.
