The True Cost of Owning a Car in Singapore
The true cost of car ownership in Singapore goes far beyond the purchase price and loan repayments. Most owners underestimate their total costs by 30-40% because they focus only on the monthly loan payment and forget about depreciation, insurance, road tax, petrol, parking, ERP, and maintenance.
Depreciation is the biggest cost, typically accounting for 40-50% of total ownership expenses. Unlike loan repayments, depreciation is a real economic loss — the value your car loses every month that you never get back.
This calculator accounts for all 7 major cost categories to give you the complete picture. Use it to compare the true cost of different vehicles, or to decide whether car ownership makes financial sense versus ride-hailing and public transport.

Frequently Asked Questions
What is the average monthly cost of owning a car in Singapore?expand_more
The average monthly cost of owning a car in Singapore ranges from $1,800 to $3,500+ depending on the vehicle type. This includes depreciation (the largest component at $800-$1,500/month), insurance ($100-$300/month), road tax ($50-$150/month), petrol ($200-$500/month), parking ($200-$500/month), ERP charges ($50-$150/month), and maintenance ($100-$200/month).
What is the biggest cost component of car ownership in Singapore?expand_more
Depreciation is by far the biggest cost of car ownership in Singapore, typically accounting for 40-50% of total ownership costs. This is because Singapore's COE system means cars have a finite 10-year lifespan before requiring expensive COE renewal. A car purchased for $150,000 with a PARF rebate of $20,000 depreciates at about $13,000 per year or $1,083 per month.
How can I reduce my car ownership costs in Singapore?expand_more
Key strategies to reduce car ownership costs: (1) Choose a car with lower annual depreciation — this is the biggest savings lever. (2) Opt for a fuel-efficient or electric vehicle to save on petrol. (3) Park at HDB lots instead of commercial parking. (4) Reduce ERP exposure by avoiding peak-hour travel on expressways. (5) Compare insurance quotes annually. (6) Follow the manufacturer maintenance schedule to avoid costly repairs.
Is it cheaper to own a car or use ride-hailing in Singapore?expand_more
For most Singaporeans who drive less than 15,000 km per year, ride-hailing (Grab, Gojek) combined with public transport is significantly cheaper than car ownership. At an average cost of $2,500/month for car ownership, you could afford roughly 100-125 Grab rides per month. However, car ownership provides convenience, privacy, and flexibility that many find worth the premium.
