THE WORKINGS

How this calculation works

Apply the entered annual percentage to the reducing value: future value = current value × (1 − depreciation rate)^years. Show cumulative value lost and average monthly loss over the chosen period.

A worked example

A R200 000 car losing 10% of its remaining value annually is worth R162 000 after two years.

Assumptions & limitations

  • The rate is your scenario, not a vehicle valuation. Make, mileage, condition, accidents, market demand and inflation affect resale prices. Running costs and finance interest are excluded.
