ERP Calculator (ERP 2.0)
Estimate daily and monthly ERP charges by zone and time period.
What is ERP (Electronic Road Pricing)?
ERP is Singapore's congestion pricing system managed by LTA. The current ERP 2.0 system uses satellite-based technology to charge motorists based on distance, time of day, and traffic conditions. Rates range from $0.50 to $6.00 per pass depending on zone and peak hours, with most zones free on weekends.

Quick Reference
- • ERP 2.0 replaced the old gantry system with satellite-based pricing in December 2023
- • CBD peak-hour charges: typically $2 to $6 per pass
- • Peak hours: weekday mornings (7:30am-9:30am) and evenings (5:00pm-8:00pm)
- • Most zones have $0 charges on weekends and public holidays
- • Rates are reviewed quarterly by LTA based on traffic conditions
How ERP 2.0 Works
ERP 2.0 uses satellite and camera-based technology to implement dynamic road pricing across Singapore. Unlike the old gantry system, ERP 2.0 can charge based on distance travelled, time of day, and real-time traffic conditions.
Charges vary by zone — the CBD and major expressways have the highest rates during peak hours (typically 7:30am-9:30am and 5:00pm-8:00pm on weekdays). Suburban roads and off-peak hours generally have lower or zero charges.
The system aims to manage traffic congestion by encouraging drivers to travel during off-peak hours or use alternative routes. Most zones are free on weekends and public holidays.

Who This Calculator Is For
Drivers Planning Route Timing
Avoiding ERP charges by adjusting departure time.
- Peak hours: 7:30–9:30am and 5:00–8:00pm weekdays
- Off-peak: $0 at most gantries
- Rates reviewed: quarterly by LTA
- Best saving tip: leave 15 minutes earlier or later than peak
Delivery and Commercial Drivers
ERP as a business operating cost.
- Tax deduction: ERP charges are a legitimate business expense
- Fleet managers: model ERP into delivery route cost
- CBD multi-gantry: can add $3–$10 per trip during peak
- Route optimisation: avoid high-rate corridors where possible
Tourists and Occasional Drivers
Understanding CashCard / NETS top-up for the In-Vehicle Unit.
- IU (In-Vehicle Unit): every Singapore car must have one
- ERP deducted: automatically from CashCard in IU
- Low balance penalty: $10 charge if CashCard has insufficient funds
- Top-up locations: petrol stations, AXS machines, selected banks
OBU Early Adopters
New on-board unit replacing CashCard-based ERP.
- OBU rollout: fully replacing existing IU system by 2030
- GPS-based: charges based on distance, not fixed gantry points
- Payment: linked to bank account (no CashCard top-up needed)
- LTA: will issue OBUs to all car owners progressively
Current IU/CashCard ERP vs New OBU GPS ERP
| Feature | IU + CashCard (current) | OBU GPS System (new) |
|---|---|---|
| Technology | Fixed gantries | GPS-based, islandwide |
| Payment method | CashCard top-up | Linked bank account (auto) |
| Charges | Per gantry passage | Per distance in charged zones |
| Flexibility | Fixed gantry locations | Dynamic — any road can be priced |
| Low balance penalty | Yes ($10 if CashCard empty) | No — auto-debit |
| Rollout | Current system | Progressive rollout to 2030 |

How can I reduce my ERP costs?expand_more
You can reduce ERP costs by travelling during off-peak hours (before 7:30am or after 9:30am for morning peak), using public transport for CBD trips, carpooling to share costs, or choosing alternative routes that avoid priced zones.
