Which is cheaper to run?

Over 5 years of average Australian driving (15,000 km/year in NSW), the Toyota Corolla Ascent Sport costs $35,840 to own and run, against $51,813 for the BYD Seal. That is a $15,973 difference — about $3,195 a year, or $266 a month.

The single biggest swing is depreciation: across 5 years the gap is $22,149. Energy is where electric cars usually win — charging at home (especially on solar or off-peak rates) costs a fraction of petrol per kilometre — while the BYD Seal's higher purchase price can narrow the gap through depreciation.

Estimates use average NSW electricity and fuel prices, typical insurance and servicing for this segment, and a 5-year depreciation model. Your numbers will vary with tariffs, driving style and resale values — use the calculator above for a tailored figure.
