Interview Questions › Guesstimate

Estimate number of petrol pumps in India

Estimate the total number of operational retail fuel stations (petrol/diesel pumps) across India.

Context

Consider national oil marketing companies (IOCL, BPCL, HPCL) and private retailers (Reliance/Jio-bp, Shell, Nayara) along national highways, state highways, and urban cities.

Clarifying questions to ask first

• Are we including private and public sector pumps?
• Does this include CNG and EV charging pumps situated within fuel stations? (Yes, all retail fuel stations).

How to approach it

1. Demand-side: Vehicle Population (Two-wheelers, Passenger Cars, Commercial Trucks/Buses) × Fuel Consumption Rate
2. Supply-side: Average fuel dispensing capacity per pump station per day
3. Geography-side: Road network distance (National/State highways + urban density coverage)
4. Reconcile against known public benchmarks (~80,000-85,000 fuel stations)

Framework: Total Fuel Stations = (Total Daily Fuel Consumed in India) / (Average Fuel Sold per Fuel Station per Day)

Sample answer

• Total on-road vehicles in India: ~250M two-wheelers, ~40M cars, ~10M commercial trucks/buses
• Total daily fuel consumed = ~350-400 Million liters/day
• Average petrol station sells ~4,500 - 5,000 liters of fuel per day
• Required stations = 400M Liters / 4,800 Liters/station = ~83,000 fuel stations

1. Calculated daily demand: 380M liters/day
2. Divided by average throughput of 4,600 liters/day/station
3. Result = ~82,600 retail fuel stations across India

Executive estimate: ~80,000 to 85,000 operational petrol pumps in India (~88% PSU oil marketing companies, ~12% private retailers).

What interviewers look for

• Vehicle Fleet Sizing in India (~300M vehicles)
• Daily Fuel Consumption per Station
• Highway vs Urban Station Density
• Benchmark Accuracy
