A used car only makes financial sense in Singapore if you drive enough to spread its fixed costs thin. Buy an older used car at the end of its certificate of entitlement and you avoid the worst of depreciation, but you still pay around S$800 to S$1,200 a month before the first kilometre. Below that mileage, GetGo car sharing or Grab usually wins. The honest answer depends on one number most people never calculate: how many trips, and how far, you make in a month. This guide runs the 2026 figures for all three so you can find your own break-even point instead of guessing.
Every transport-cost comparison in Singapore reaches a different conclusion because each one quietly assumes a different driver. A car looks cheap if you drive 30,000km a year and dear if you drive 5,000km. Grab looks cheap if you take two short rides a week and ruinous if you take four a day. So the useful framing is not "is a used car cheaper than Grab" but "at what level of use does each option win".
Three things drive the answer: how many trips you make, how far each one is, and how predictable your schedule is. A used car carries high fixed costs (loan, insurance, road tax, parking) that barely move whether you drive once a week or every day, plus low variable costs (petrol, ERP). Grab is the mirror image, almost no fixed cost and high per-trip cost. Car sharing sits in between. Match the cost shape to your travel pattern and the cheapest option falls out on its own. Our car cost calculator lets you plug in your own numbers if you want to skip the worked examples below.
The case for a used car in Singapore is that someone else already paid the brutal early depreciation. A 7 to 9 year old car priced around S$20,000 to S$40,000 has only a few years of certificate of entitlement (COE) left, so the COE premium baked into the price is nearly used up. With Category A COE closing at S$123,847 in the second June 2026 exercise, an older car lets you sidestep most of that cost up front.
The trade-off arrived in Budget 2026. The government cut the Preferential Additional Registration Fee (PARF) rebate schedule for cars deregistered from the second February 2026 COE exercise onwards, and capped the rebate at S$30,000 instead of S$60,000. A car eight to nine years old now returns just 10% of its original ARF when scrapped, down from 55%. The resale value of an older used car is thinner than it was a year ago, which makes the monthly running cost the figure that matters most.
Here is a realistic monthly stack for an older mass-market used car in 2026. Treat each line as a from-figure, since insurance and parking swing widely by profile and postcode.
| Cost item | Typical monthly amount | Notes |
|---|---|---|
| Car loan repayment | S$350 to S$650 | Shorter tenure on older cars; many buyers pay cash |
| Insurance | S$80 to S$150 | Higher for younger drivers and performance models |
| Road tax | About S$62 | Roughly S$742 a year for a 1.6L petrol car |
| Season + casual parking | S$120 to S$250 | HDB season parking plus carpark charges |
| Petrol | S$150 to S$300 | Depends on mileage and fuel economy |
| ERP + servicing + wear | S$80 to S$200 | ERP, oil changes, tyres, inspection |
| Total | S$800 to S$1,200 | Excludes depreciation and the one-time price |
The monthly table understates the true cost because two big items sit outside it. The first is depreciation, the gap between what you pay and what you get back when you sell or scrap. On an older car with a slashed PARF rebate, you may recover only a small COE rebate at deregistration, so most of the purchase price is gone. The second is the one-time entry cost: the down payment plus a roughly S$25 ownership transfer fee via LTA OneMotoring, and a pre-purchase inspection of around S$100 to S$300 that can save you thousands.
Financing also tightens the picture. The Monetary Authority of Singapore caps car loans at 60% or 70% of the open market value or purchase price depending on the car's value, with a maximum seven-year tenure, and lenders shorten that further on older cars so the loan ends within the COE's remaining life. We break the financing rules down in our used car buying guide, and the ARF glossary entry explains how the registration fee feeds your rebate. Fold depreciation back in and a used car driven lightly can cost well over S$1,500 a month all-in.
Car sharing flips the cost structure. There is no loan, no insurance bill, no road tax and no parking season pass, because you only pay when you drive. GetGo, Singapore's largest operator, charges by the hour plus a per-kilometre fee, with fuel and basic insurance included and no membership or deposit, as listed on its official rates page as of June 2026.
An economy GetGo car runs from S$3 an hour off-peak up to S$9 to S$10 an hour at peak, with mileage at S$0.44/km for petrol cars and S$0.29/km for electric ones. A three-hour weekend trip covering 48km in an economy petrol car works out to roughly S$36 in fuel-and-everything-included pricing. Take two such trips a week and you are around S$300 a month, comfortably under the floor of used-car ownership.
The catch is availability and the clock. Cars near you can be booked out at peak times, and because you pay by the hour, a long day or a trip with lots of waiting (a full-day outing, a hospital visit) adds up fast. Past roughly 40 to 60 hours of driving a month, car sharing starts to cost more than simply owning. For occasional users, though, it remains the cheapest way to have a car when you need one.
Grab, Gojek, TADA and Ryde carry no ownership cost at all. You pay per trip, the driver handles parking and ERP, and you never think about insurance renewal or servicing. A typical 10km ride costs around S$12 to S$18 depending on time of day and surge, with GrabCar Economy priced from a base fare plus roughly S$0.83/km and a per-minute charge as of mid-2026.
For light users this is unbeatable. Two short rides a week is maybe S$120 to S$200 a month, a fraction of car ownership. The cost curve bites for heavy users. Budget Direct's own modelling put a year of four 12km daily Grab trips at around S$15,760, against roughly S$15,113 for owning a 1.6L Toyota Corolla Altis over the same distance, so at high, predictable daily mileage the two converge and a used car can edge ahead once you value the PARF or COE rebate you get back. If you commute daily on a fixed route, model both before defaulting to Grab. See our deeper car sharing vs Grab vs taxi comparison for the trip-by-trip maths.
Stack the three side by side and the pattern is clear. Each option owns a band of usage, and the cheapest choice is whichever band you live in for most of the month.
| Your travel pattern | Cheapest option | Rough monthly cost | Why |
|---|---|---|---|
| A few rides a week, short trips | Grab / ride-hailing | S$120 to S$300 | No fixed cost; you only pay per trip |
| Weekend outings, errands, infrequent | Car sharing (GetGo) | S$200 to S$500 | Pay by the hour with fuel included |
| Daily long commute, fixed route | Used car | S$800 to S$1,200+ | Fixed costs spread thin over high mileage |
| Family with kids, child seats, school runs | Used car | S$900 to S$1,300+ | Convenience, capacity, and rebate at scrap |
If your Grab spending stays under about S$700 a month, owning almost never pays. Between S$700 and S$1,000 a month it becomes a genuine toss-up that turns on convenience, child seats and how much you value not waiting in the rain. Only above roughly S$1,000 a month of consistent, scheduled travel does a used car reliably win on pure cost, and even then mostly because of the rebate you eventually claw back. Before committing, run your real monthly figure through the car cost calculator rather than trusting a gut feel.
Only if you drive a lot. A used car costs roughly S$800 to S$1,200 a month before petrol, so it beats Grab only once your monthly ride-hailing spend consistently passes about S$1,000 on a predictable route. Below that, Grab or car sharing is cheaper.
Expect around S$800 to S$1,200 a month for a 7 to 9 year old mass-market car, covering loan or financing, insurance, about S$62 of road tax, parking, petrol, ERP and servicing. Depreciation and the one-time purchase price sit on top of that figure.
Yes. From the second February 2026 COE exercise, PARF rebates were cut sharply and capped at S$30,000, so older used cars now return far less when scrapped. That weakens the resale value argument and makes the monthly running cost the figure that matters most.
Car sharing wins for occasional use, roughly under 40 to 60 driving hours a month. A weekend trip of 48km in an economy GetGo car costs about S$36 all-in, so two trips a week is around S$300 a month, well below the cost floor of owning a used car.
