Why is depreciation the key number for Singapore cars?

Because COE adds a large fixed, non-recoverable cost to every car, the fairest way to compare cars in Singapore is annual depreciation: what the car costs you per year of ownership after accounting for the guaranteed money back at deregistration.

What is the PARF rebate?

The Preferential ARF rebate is a percentage of the ARF you paid, returned when the car is deregistered before it turns 10 years old. It ranges from 75% of ARF for cars under 5 years old down to 50% at just under 10 years.

Where do I find my ARF or PARF figure?

Log in to OneMotoring with Singpass and check your vehicle's registration details, or refer to your Vehicle Sales Agreement. If you know your exact PARF rebate figure, enter it directly for the most accurate result.

Tool 02 — Depreciation

Singapore Car Depreciation Calculator

Because COE adds a fixed, non-recoverable cost to every car, depreciation here works differently from most other markets — and it's the single number that matters most when deciding whether to buy, sell, trade in, or hold. This calculator uses your purchase price, ARF paid, and COE dates to work out true annual depreciation, so you can compare any two cars on equal footing before you negotiate.

PARF rules — registration period

Budget changes cut PARF sharply for newer registrations: the S$60k cap mainly bites high-ARF (big/luxury) cars registered from Feb 2023, while cars registered from Mar 2026 get just 5% of ARF, capped at S$30k.

Known PARF rebate (S$) — optional override

If filled, this replaces the ARF-based estimate. The estimate assumes deregistration in the final PARF band (50% of ARF).

Implied price = quoted depreciation × years of COE remaining + deregistration value. Use this to sanity-check whether a listing's asking price matches its advertised depre — if the seller quotes S$14,500/yr with 6 years left and a S$10k paper value, the car should cost about S$97,000.

Annual depreciation = (purchase price − deregistration value) ÷ years of COE remaining. PARF bands step down as the car ages, so cars crossing the 5-year mark depreciate faster — verify your exact rebate on OneMotoring.

Common questions

Which PARF band applies to my car?

The rebate is a sliding percentage of your ARF based on the car's age at deregistration: 75% under 5 years, then stepping down 5% per year to 50% at just under 10 years. Deregister after 10 years (e.g. after a COE renewal) and the PARF rebate is forfeited entirely.

Why does my dealer's depreciation figure differ?

Listings usually quote depreciation off the asking price and assume deregistration exactly at COE expiry. Your actual figure moves with the price you really pay, your exact PARF rebate, and any COE rebate if you deregister early. This tool lets you control those inputs.

Does this include running costs?

No — depreciation is purely the capital cost of the car itself. Road tax, insurance, fuel, parking and servicing come on top. But depreciation is usually the single largest cost, which is why it's the comparison number that matters.
