Step-by-Step Worked Calculation

Scenario: Depreciation of a $30,000 Car

Calculate vehicle value after 3 years at a 15% declining balance rate.

1

Step 1: Set Price to $30,000, rate to 15% (0.15), and years to 3.

2

Step 2: Year 1 value: $30,000 * (1 - 0.15) = $25,500.

3

Step 3: Year 2 value: $25,500 * 0.85 = $21,675.

4

Step 4: Year 3 value: $21,675 * 0.85 = $18,423.75. Total lost is $11,576.25.
