The National Highways Authority of India (NHAI) has announced revised toll rates effective April 1, 2026, with an average increase of 5-7% across national highways. This annual revision, based on the Wholesale Price Index (WPI) inflation formula, ensures that toll rates keep pace with maintenance costs and infrastructure development. The 2026 revision comes as part of NHAI's mandate under the National Highways Fee (Determination of Rates and Collection) Rules, 2008.
For a standard car (Vehicle Class 1), the per-kilometre toll rate has increased from the previous ₹1.25 to approximately ₹1.33. This means a typical 100 km highway journey now costs around ₹133 for a car using FASTag, compared to ₹125 last year. The actual toll at any plaza depends on the specific stretch length, construction cost, and traffic density factors approved by NHAI.
NHAI classifies vehicles into multiple categories with specific toll multipliers. The base rate (Car/SUV/Jeep) has a multiplier of 1.0. Light Commercial Vehicles (LCV) are charged at 2.0x, while 2-axle trucks pay 2.5x. Three-axle commercial vehicles have a 3.0x multiplier, and multi-axle trucks (4+ axles) pay up to 4.5x. Heavy Construction Machinery (HCM) and Earth Moving Equipment (EME) attract the highest multiplier of 5.0x.
These multipliers are designed to account for the disproportionate wear and tear caused by heavier vehicles. A truck with 4 axles causes exponentially more damage to road surfaces than a car, justifying the 4.5x multiplier. TollRoute automatically detects your vehicle class when you enter your vehicle details, ensuring accurate cost estimates for any journey on Indian highways.
FASTag users continue to enjoy a 10% discount on toll charges compared to cash payments, a policy maintained by NHAI to encourage digital payments and reduce congestion at toll plazas. For example, if the cash toll for a car at a plaza is ₹110, the FASTag user pays only ₹100. This discount applies across all vehicle classes and is automatically credited when the FASTag is scanned at the toll booth.
The monthly pass scheme remains one of the most cost-effective options for frequent commuters. Regular users who make 20 or more trips per month through the same plaza can purchase a monthly pass at approximately 30% of the total toll cost. These passes are valid for the calendar month and can be obtained through the FASTag portal or at select toll plaza offices. The scheme is particularly popular on commuter corridors like Delhi-Gurugram and Noida-Delhi.
Toll rates in India are determined using a formula that considers the project cost, maintenance expenses, interest on loans, and a reasonable return on investment for the concessionaire. Rates are revised annually based on the change in the Wholesale Price Index (WPI), specifically using the inflation rate for fuel, power, and manufactured products. The base year for the current cycle is 2019-20.
NHAI also factors in traffic volume projections, with higher-traffic corridors subsidising lower-traffic stretches in some cases. The Fee Rules mandate that any rate revision must be published 30 days in advance, allowing users to plan their budgets accordingly. TollRoute tracks these revisions and updates its database within 24 hours of official notification, giving you the most accurate cost estimates.
