Variable vs. Fixed Costs
Variable costs (like fuel) increase with every kilometre or mile driven. Fixed costs (like insurance and registration) stay the same regardless of how much you drive. When you drive more, your fixed cost per unit of distance decreases — which is why cost per km or mile drops for high-distance drivers.
Depreciation: The Biggest Hidden Cost
Depreciation is often the single largest cost of vehicle ownership — sometimes 40–50% of total cost for new vehicles. A $40,000 car losing 15% per year loses $6,000 in value annually — equivalent to roughly $0.40/mile at 15,000 miles (24,000 km) per year.
