Kolkata to Patna Cab Fare, Route & One-Way vs Round Trip

The Kolkata to Patna cab fare for a one-way trip typically falls between Rs 8,500 and Rs 13,000 depending on the car type, while a round trip runs roughly Rs 14,000 to Rs 22,000. The drive covers about 580-600 km and takes 11-13 hours via NH-19 (the old NH-2 / Grand Trunk Road) through Durgapur, Asansol and Dhanbad. Below is a complete, locally informed breakdown of routes, car-wise rates, timings and which booking type actually saves you money.

Kolkata to Patna distance, route and drive time

From central Kolkata, the most-used road route to Patna is via NH-19 heading west out of the city, then onto NH-2/NH-19 corridor through the industrial belt of West Bengal before crossing into Jharkhand and finally Bihar. The total road distance is approximately 580-600 km, and a realistic door-to-door drive time is 11 to 13 hours including a meal stop and short breaks.

The main alternative is the route via NH-12 and Berhampore towards Farakka, then NH-80/NH-31 along the Ganga into Bihar. This riverside route is slightly longer at around 610-640 km but useful if you want to break the journey near Murshidabad. Most drivers prefer NH-19 for its better-maintained four-lane stretches and quicker overall time.

Key landmarks and halt points along the way

• Durgapur & Asansol (around 160-210 km from Kolkata) — good for a breakfast or tea stop; plenty of clean highway dhabas and fuel pumps.
• Dhanbad (around 260 km) — the coal-belt city marks roughly the halfway point; ideal for a proper lunch break.
• Barhi / Bagodar junction in Jharkhand — where traffic merges towards the Bihar leg.
• Gaya turnoff & Bihar Sharif belt — the final stretch into Patna along NH-83/NH-22 connections.

Kolkata to Patna cab fare by car type (2026 indicative)

Fares depend heavily on car category, fuel rates, the season and whether you book one-way or round trip. The table below gives realistic 2026 indicative ranges for the Kolkata-Patna outstation route. These cover the cab, driver and standard running; toll, state border tax and parking are usually extra unless your quote says all-inclusive.

Note: All fares are indicative for 2026 and vary with season, fuel prices, traffic, tolls and exact pickup/drop points. Festive periods like Chhath Puja and Diwali, when demand for Patna-bound cabs spikes, can push rates 15-25% higher.

For a comfortable long-distance run on this route, a sedan is the sweet spot for 2-3 passengers, while families of 5-6 with luggage are far better off in an Ertiga or Innova given the 12-hour duration. If you are also comparing short city hops or airport runs alongside this trip, our Kolkata airport cab fare guide breaks those down separately.

One-way vs round trip: which one to choose

This is the single biggest factor in your final bill, so it deserves a clear answer. The difference comes down to whether the cab returns empty.

When one-way makes sense

Choose one-way if you are relocating, flying back from Patna, or staying in Bihar for several days. On paper a one-way fare looks like a great deal, but remember that on the Kolkata-Patna sector many operators still charge close to a 1.5x to 1.8x of a single leg, because the driver must cover the empty return run and a night halt. Genuine one-way pooled cabs exist but availability is limited and timing is less flexible.

When round trip is cheaper per kilometre

If you are visiting Patna for 1-3 days and returning to Kolkata by road, a round trip is almost always the better value. You typically pay a per-km rate (around Rs 13-17/km for sedans in 2026) plus a daily driver allowance of Rs 400-600 and night charges. Because the same vehicle handles both legs, the effective cost per kilometre drops sharply compared to two separate one-way bookings.

• One-way: best for permanent moves, airport drops, or open-ended stays.
• Round trip: best for short visits, weddings, Chhath Puja family trips, and business runs with a fixed return.
• Multi-day round trip: add Rs 400-600 per extra night for driver halt; confirm whether local sightseeing in Patna is included.

What is included and what is extra

Knowing what sits outside the base fare prevents nasty surprises at the Bihar border. On the Kolkata-Patna route, the following are usually charged on top of the indicative fare unless your operator quotes an all-inclusive package:

• Tolls on NH-19/NH-2 — several toll plazas across Bengal, Jharkhand and Bihar add up to roughly Rs 700-1,000 one-way.
• State permit / border tax when the cab crosses from West Bengal into Jharkhand and Bihar.
• Driver night allowance for round trips and overnight halts.
• Parking at hotels or stations in Patna.
• GST where applicable on the booking.

Always ask whether your fare is “all-inclusive” or “base + tolls/tax”. A clear written quote is the mark of a reliable operator. Our outstation cab service provides itemised quotes so you know exactly what you are paying for before the wheels turn.

Best time to travel and local tips

The most comfortable window for the Kolkata-Patna drive is October to March, when Bengal and Bihar enjoy cooler, drier weather and highway visibility is good. The monsoon months of July-September can mean waterlogging near low-lying Ganga belt stretches and slower going around Farakka if you take the river route.

• Start early — leaving Kolkata by 5:30-6:00 AM means you clear the Durgapur-Asansol belt before heavy truck traffic builds and reach Patna comfortably by evening.
• Carry valid ID for all passengers; inter-state travel can involve checkpoint stops, especially during festivals.
• Plan around Chhath Puja (usually late October/November) — Patna sees enormous inbound demand, so book your cab a week or more in advance.
• Keep cash for tolls as a backup even though most plazas accept FASTag.
• Eat at busy, well-reviewed highway dhabas around Asansol and Dhanbad rather than isolated ones.
