What is a Total Ownership Cost Calculator?
A total ownership cost calculator adds up every expense of owning a car in Singapore — depreciation, insurance, road tax, petrol, parking, ERP, and maintenance. Most owners underestimate their true costs by 30-40% by focusing only on loan repayments and ignoring depreciation, which alone accounts for 40-50% of total expenses.

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.
Is an electric car cheaper to own than a petrol car in Singapore?expand_more
It depends mainly on how much you drive. EVs cut the running costs — electricity is cheaper per km than petrol, and there are fewer moving parts to service — but the large fixed costs (COE and depreciation) are similar, and EVs carry an additional usage-based road tax component to offset the fuel duty they avoid. The more kilometres you cover each year, the more the lower running cost works in the EV's favour. The EV vs Petrol 10-Year Cost calculator models the break-even for your own mileage.
