Understanding Singapore's ERP System

Electronic Road Pricing (ERP) is Singapore's traffic management system that charges motorists for using busy roads during peak hours. The system helps reduce traffic congestion and encourages the use of public transport and alternative routes.

ERP Operating Hours

Weekdays: Generally 7:00 AM to 8:00 PM
Saturdays: Generally 7:00 AM to 3:00 PM
Sundays & Public Holidays: No ERP charges
Peak Hours: 8:00 AM - 9:30 AM and 6:00 PM - 8:00 PM (weekdays)

Vehicle Categories & Rates

Cars: Standard rates (S$0.50 - S$6.00 per gantry)
Motorcycles: 50% of car rates
Taxis: Same as cars
Buses: S$1.00 - S$3.00 per gantry
Light Goods Vehicles: Same as cars
Heavy Goods Vehicles: 125% of car rates

Major ERP Zones

Central Business District (CBD): Highest charges during peak hours
Orchard Area: Shopping district with moderate charges
Marina Centre: Tourist and business area
Expressways: CTE, PIE, ECP, AYE with variable pricing
Arterial Roads: Major connecting roads with lower charges

Money-Saving Tips

Travel during off-peak hours to avoid high charges
Use alternative routes that avoid ERP gantries
Consider public transport for trips to ERP zones
Plan return trips during lower-rate periods
Check ERP rates regularly as they are reviewed quarterly

Disclaimer: This calculator provides estimates based on current ERP rates and typical routes. Actual charges may vary due to real-time traffic conditions, route changes, or rate adjustments by LTA. ERP rates are subject to quarterly reviews and may change. Always check current rates on the LTA website and ensure sufficient CashCard balance before travel.

What Is the ERP Cost Calculator?

The Electronic Road Pricing (ERP) Cost Calculator is an online tool that helps drivers in Singapore estimate their ERP charges before starting a trip. It calculates potential fees based on your selected route, time of travel, vehicle type, and Other conditions like traffic and return trips. This enables more informed travel planning, potentially saving you money and time.

How ERP Charges Are Calculated

ERP rates vary based on location, time of day, and vehicle category. The calculator uses this data to estimate total charges. Charges increase during peak hours and for larger vehicles.

ERP Cost Formula:

Total Cost = Σ (Gantry Rate × Vehicle Type Multiplier)

Where each gantry has different rates depending on the time of day (off-peak, shoulder, peak, super-peak), and the vehicle multiplier reflects the type of vehicle (e.g., motorcycles cost 50% of car rates).
