Why living in Bengaluru is expensive as compared to Chennai, Delhi, Kolkata, Mumbai

The farther a person stays from the central business district (CBD), greater the chances of lower cost for housing, but the Namma Metro in Bengaluru cannot take a commuter beyond 25 km from the core areas

Commuters in Mumbai, Kolkata, and Chennai not only pay less for rail-based commuting, but also enjoy access to a much larger housing market because their rail systems connect distant, lower-cost suburbs to the city’s economic core. Bengaluru commuters generally pay more while also having a significantly smaller rail-served commuter radius***.

In any case, for shorter distances, commuters might opt for personal vehicles even if the cost is higher compared to public transport. The benefits of a metro or suburban rail system — in terms of economics and convenience — become noticeable only once the daily travel distance gets longer.

The farther a person stays from the central business district (CBD), greater the chances of lower cost for housing. Let us see how far a person can stay from the CBD of each city.

Maximum practical commute

In Mumbai, Kolkata and Chennal, a person can live over 50 km away from the core areas and still reach the CBD using a combination of rail and metro. Daily commute exceeding 100 km one-way is not unusual. The suburban rail network was built precisely for this purpose.

Delhi’s metro is vast, but it is primarily an urban metro. People can comfortably commute from Gurugram, Noida, Greater Noida (with one change), Ghaziabad, and Faridabad up to the centre of the city — Connaught Place.

Among the major metro cities, Bengaluru has the smallest rail commuter catchment. Today, someone living near Whitefield, Kengeri or Madavara can travel to the CBD by Namma Metro, but the practical periphery-to-CBD distance is only 20-25 km. Even after the airport line opens, Bengaluru will still be far behind Mumbai, Chennai, and Kolkata in terms of rail-accessible commuting radius.

A commuter in Mumbai can live up to 100 km away from the CBD, Kolkata can live 70-100 km away, Chennai can live 60-75 km away, and in Delhi NCR can live 30-40 km away. But, Bengaluru is typically limited to 20-25 km (average 22.5 km) by the metro network.

Monthly commute cost at maximum practical rail distance

The cities with the largest suburban rail systems are also the cheapest for long-distance commuters.

The difference is significant. A commuter living 100 km from Mumbai’s CBD can expect to spend only about ₹2,080/month on travel while a commuter living just 22-25 km from Bengaluru’s CBD spends roughly ₹3,850/month.

The real advantage of Mumbai, Kolkata and Chennai is not merely that commuters pay less. It is that those cities allow workers to access employment centres from much farther away at a lower cost per kilometre. Bengaluru commuters pay among the highest rail-based commuting costs in India while simultaneously having the smallest rail-accessible residential catchment around the CBD. This effectively narrows the range of affordable housing options available to workers who depend on public transport.

1. Rail-based cities dramatically expand housing choice, which has a direct impact on savings. In Mumbai, Kolkata, and Chennai, a person can live 70-100 km from the CBD and commute by rail. The cost remains relatively low because suburban rail spreads fixed infrastructure costs across very large passenger volumes and long distances.

2. Metro-only systems are efficient, but not necessarily cheap

This explains why Bengaluru and, to a lesser extent, Delhi NCR show higher costs per kilometre despite having modern metro systems. The commuter travels a shorter distance, but pays a higher fare structure than a suburban-rail commuter.

The metro’s strength is not cheapest transport.

Its strength is in getting a passenger from A to B in a predictable amount of time regardless of road congestion.

3. Private vehicles become economically unviable at scale.

If we compare the same distances with private vehicles:

For Bengaluru, earlier calculations suggest:

Private 2-wheeler: ~₹2.5/km

At 22 working days/month: 22.5 km one way (average max distance to CBD from periphery 20-25 km)

Bike ≈ ₹2,500-3,000/month

Car ≈ ₹8,000-10,000/month

At larger distances: 50-100 km one way, the costs become enormous.

A 100-km one-way commute in a private car could easily exceed ₹15,000-20,000/month fuel, plus maintenance, depreciation, insurance, parking, tolls.
