E-way bill validity calculator for GST consignments
An e-way bill is only valid for a set number of days, worked out from the distance the goods travel. This e-way bill validity calculator applies Rule 138(10) of the CGST Rules: one day for up to 200 km and one more day for every further 200 km or part of it — or 20 km a day for over-dimensional cargo and multimodal shipments with a sea leg. It then gives the exact expiry, which is always midnight, not 24 hours after generation.
It also shows the window in which the transporter can extend an expiring bill, lists what each validity day covers, estimates the extra days an extension gives for the distance left, and checks whether the ₹50,000 consignment value limit applies. Everything is calculated in your browser.
How to use the E-way Bill Validity Calculator
- Enter the date and time the e-way bill was generated — in practice, when Part-B (vehicle details) was first entered — or press Use now.
- Enter the approximate distance in kilometres. The portal fills this in from the PIN codes; you can check it with the official PIN-to-PIN distance search.
- Choose Regular cargo or Over-dimensional or ship leg.
- Optionally enter the consignment value to check the ₹50,000 limit.
- Read the validity days, the expiry time and the extension window. If a truck is running late, enter the distance still to travel for an extension estimate, and copy the summary.

E-way bill validity rules (as of 19 October 2026)
Source: CGST Rules, 2017, Rule 138(10), as published on the CBIC tax information portal. The 200 km slab applies from 1 January 2021 (Notification 94/2020-Central Tax); before that it was 100 km, which is why some older guides still say so. The Commissioner may extend validity for notified categories of goods. Over-dimensional cargo means a single indivisible load exceeding the size limits in rule 93 of the Central Motor Vehicles Rules, 1989.
| Distance | Regular cargo | Over-dimensional cargo or multimodal with ship |
|---|---|---|
| Up to 200 km | 1 day | — |
| Each further 200 km or part | +1 day | — |
| Up to 20 km | — | 1 day |
| Each further 20 km or part | — | +1 day |
How the expiry is counted — worked example
The rule’s Explanation says validity is counted from the time of generation and each day ends at midnight of the day after the date of generation. So a bill generated at 00:04 or at 23:58 on 14 March, for up to 200 km, expires at midnight between 15 and 16 March either way. Generate late in the evening and you get almost a full extra day; generate just after midnight and you get almost two.
Example: 650 km of regular cargo, generated at 14:30 on Monday 19 October 2026. 650 ÷ 200 = 3.25, rounded up to 4 days. Day 1 ends at midnight on Tuesday 20 October, so day 4 ends at 23:59 on Friday 23 October — about 105 hours of driving time.
Extending an e-way bill
- Rule 138(10) allows the transporter to extend validity in exceptional circumstances such as breakdown, accident, natural calamity, law and order problems or trans-shipment delay, and says the extension may be made within eight hours from the time of expiry.
- The e-way bill portal’s FAQ describes the option as available from 8 hours before to 8 hours after expiry. The transporter gives the reason, the current place, the remaining distance and Part-B details; Part-A cannot be changed.
- The extension is based on the remaining distance, using the same 200 km (or 20 km) slab. Once both windows pass, a new e-way bill is needed.
E-way Bill Validity Calculator FAQ
What is the validity of an e-way bill?
One day for up to 200 km and one more day for each further 200 km or part, counted to midnight. For over-dimensional cargo or multimodal shipments with a ship leg it is one day per 20 km. Enter your distance in the e-way bill validity calculator to get the exact expiry.
Does an e-way bill expire 24 hours after generation?
No. Each validity day ends at midnight. Day 1 ends at midnight at the end of the day after the date of generation, whatever the time of generation.
What is the e-way bill limit?
An e-way bill is required when the consignment value — including GST — exceeds ₹50,000, under Rule 138(1). Some states set their own limits for movement within the state, so check your state’s notification.
How is the e-way bill distance calculated?
The portal auto-calculates the road distance between the dispatch and delivery PIN codes. This tool does not estimate PIN distances; use the official PIN-to-PIN distance search linked above and enter that figure.
Can I extend an expired e-way bill?
Yes, within the extension window: the rule says within 8 hours of expiry, and the portal opens the option 8 hours before expiry. After that a fresh e-way bill must be generated.
Is this legal advice?
No. It applies the published rule to the dates and distance you enter. The e-way bill portal’s calculation governs, and rules can change by notification.
