Understanding Singapore's COE System

The Certificate of Entitlement (COE) system controls vehicle population growth in Singapore. Every vehicle must have a valid COE to be driven on roads, obtained through a bidding system conducted twice monthly.

COE Categories
  • Category A: Cars with engine capacity up to 1,600cc and maximum power output up to 130bhp
  • Category B: Cars with engine capacity above 1,600cc or maximum power output above 130bhp
  • Category C: Goods vehicles and buses
  • Category D: Motorcycles
  • Category E: Open category (can be used for any vehicle type)
Additional Registration Fee (ARF)
  • First S$20,000: 100% of OMV
  • Next S$30,000: 140% of OMV
  • Next S$30,000: 180% of OMV
  • Remaining amount: 220% of OMV
Key Cost Components
  • Open Market Value (OMV): Purchase price of vehicle before taxes
  • COE Premium: Bidding price for the certificate
  • Additional Registration Fee: Tiered percentage of OMV
  • Excise Duty: 20% of OMV for most cars
  • GST: 8% on (OMV + ARF + COE)
  • Road Tax: Based on engine capacity

Disclaimer: This calculator provides estimates based on current regulations and typical market rates. Actual costs may vary based on specific vehicle models, dealer pricing, financing terms, and regulatory changes. COE premiums fluctuate with each bidding exercise. Always verify current rates and regulations with LTA and authorized dealers before making purchase decisions.

What Is the COE Calculator?

The COE Calculator is an interactive tool that helps car buyers in Singapore estimate the full cost of owning a car. It factors in the Certificate of Entitlement (COE), Additional Registration Fee (ARF), taxes, loan interest, and monthly operating costs. This tool is particularly helpful for planning a vehicle purchase and managing long-term car ownership expenses.

How the Calculator Works

This calculator uses key cost components defined by Singapore's vehicle ownership policies. By inputting your vehicle's Open Market Value (OMV), COE category, and Other related costs, the calculator breaks down:

  • Total upfront cost including COE premium, ARF, and registration fees
  • Monthly and yearly running costs such as petrol, parking, and maintenance
  • Depreciation estimates and potential COE renewal costs

Formula Highlights

Additional Registration Fee (ARF)
ARF = Sum of (portion of OMV in tier × rate)
Example Tiers:
- First S$20,000: 100%
- Next S$30,000: 140%
- Next S$30,000: 180%
- Remaining: 220%
Excise Duty
Excise Duty = OMV × 20%
goods and services tax (GST)
GST = (OMV + ARF + COE Premium) × 8%
Monthly Loan Installment
Monthly Payment = [P × r × (1 + r)^n] / [(1 + r)^n – 1]
Where:
P = Loan amount
r = Monthly interest rate
n = Number of monthly payments
