Guide to Toll Rates in India (NHAI & FASTag)
Calculating the cost of road travel in India involves more than just fuel expenses; highway tolls constitute a significant portion of the trip budget. With the implementation of FASTag and the National Highway Authority of India (NHAI) modernizing toll collection, understanding how rates are calculated is essential for logistics planning and personal travel.
How Are Toll Rates Calculated?
In India, toll rates on National Highways are governed by the National Highways Fee (Determination of Rates and Collection) Rules, 2008. The rates are revised annually, typically effective from April 1st. The calculation depends on several key factors:
Vehicle Classification: Tolls are tiered based on the size, axle count, and commercial nature of the vehicle.
Distance: The primary factor is the length of the highway stretch being used. The base rate is defined per kilometer.
Structures: Special structures like bridges (over 60m), tunnels, and bypasses have higher rates (often 10x the normal road rate) to recover construction costs.
Vehicle Categories and Average Rates
While specific rates differ by plaza, the following are the standard categorization and approximate base rates used for estimation:
Vehicle Class
Description
Approx. Rate (₹/km)
Car / Jeep / Van
Private passenger vehicles and light goods vehicles.
₹1.75 – ₹2.00
LCV
Light Commercial Vehicles (Mini-trucks).
₹2.80 – ₹3.00
Bus / Truck
Heavy vehicles with 2 axles.
₹5.90 – ₹6.10
3-Axle Vehicles
Heavy commercial vehicles with 3 axles.
₹6.50 – ₹6.80
MAV (4-6 Axles)
Multi-Axle Vehicles, heavy machinery.
₹9.30 – ₹9.50
Oversized (7+ Axles)
Massive earth movers and specialized transport.
₹11.30+
Return Journey and Pass Discounts
Frequent travelers can avail of specific discounts at toll plazas:
Return Journey (24 Hours): If you pass through the same toll plaza on your return leg within 24 hours of the first transaction, the return trip is charged at a 50% discount (Total cost = 1.5x Single trip).
Monthly Pass (Local Non-Commercial): Residents living within 20km of a toll plaza can often apply for a monthly pass (approx. ₹330/month for FY 2024-25) for unlimited trips.
Monthly Pass (Commercial): For frequent commercial users, a pass covering 50 single journeys in a month is usually priced at 2/3rds of the total single journey cost.
FASTag vs. Cash
It is mandatory to use FASTag for toll payments on National Highways. If a vehicle enters a FASTag lane without a valid tag, the driver is liable to pay double the toll fee as a penalty. Always ensure your FASTag wallet has sufficient balance before starting a long highway trip to avoid blacklisting and penalties.
