About this tool
Calculate an e-way bill's validity window from the distance and generation time.
The E-Way Bill Validity Calculator applies Rule 138(10) of the CGST Rules, 2017 to work out how long an e-way bill remains valid: one day for the first 200 km and one further day for every additional 200 km or part of it for ordinary cargo, and blocks of 20 km instead for over dimensional cargo or a multimodal shipment with a leg by ship. It also applies the Explanation to that rule, under which validity expires at midnight of the day following the date of generation, and shows the eight-hour window either side of expiry in which a transporter may extend the bill. For consignors, transporters and logistics teams planning a route.

Enter 'Approximate distance (km)', the 'Generation date' and 'Generation time (24h HH:MM)', or click the '420 km regular' or '65 km ODC' example preset.
Set 'Movement type' to 'Regular / non-ODC' or 'Over-dimensional cargo' to switch between the 200 km and 20 km per day slabs.
Read the '<n> days estimated validity' with the Slab, Estimated end and 'Extension window' rows, then Copy it or Download e-way-bill-validity-calculator.txt.
Switches between the 200 km and 20 km blocks in one place.
Applies the midnight rule instead of counting 24-hour periods from dispatch.
Displays the eight hours before and after expiry in which Part B can be updated.
One day for the first 200 km and one additional day for every further 200 km or part of it. A 450 km journey therefore carries three days of validity. Over dimensional cargo and multimodal shipments with a leg by ship use 20 km blocks instead.
At midnight of the day immediately following the date of generation, for a one-day bill. The Explanation to Rule 138(10) counts a day that way rather than as 24 hours, so a bill generated at 11 pm on 5 July still runs to the end of 6 July.
Yes. The transporter may update Part B and extend the validity within eight hours before or eight hours after expiry, under the third proviso to Rule 138(10). The Commissioner can also extend the period by notification for particular categories of goods.
The consignment can be detained and released only on payment of penalty under section 129 of the CGST Act. Extend the bill on the portal within the eight-hour window rather than continuing the journey, and consult your tax adviser if a detention notice has already been issued.
