Trip Fuel Stop Calculator

Tank range divided into trip distance, minus the tank you start with, is how many fuel stops to plan. An 850 km run with a 400 km range needs 2 stops in this sketch (ceil(850/400) − 1). That is a Delhi–Lucknow–kind of distance, not a promise that every dhabha pump is open at 2 a.m.

Fares and time, not tickets

Families driving Bengaluru–Hyderabad or Kolkata–Puri still run to fumes because “the next town is close.” IndiaKit forces a stop count so you leave with a reserve. The fuel-cost tool is the rupee cousin; this one is logistics.

The sketch behind the figure

Stops = max(0, ceil(distance / range) − 1). Defaults 850 km and 400 km → 2. If range is 0, stops are 0 in code — treat that as invalid input.

Always keep a reserve; do not plan to hit 0 km remaining at the pump. Hill ghats and AC cut range.

FASTag and toilets are not fuel. The toll tool is separate.

850 km, 400 km tank, two planned pumps

A family drives 850 km with a car that honestly does 400 km a tank. IndiaKit says plan 2 fuel stops. They still fill at 80 km remaining, not at 2 km, because NH services can be closed.

Night, surge and live apps sit outside this box

No map of petrol pumps. No live fuel price. Range is what you type, not the sticker. Do not run the tank empty.

Common questions

Why subtract 1?

Because you start with a tank. ceil(distance/range) is the number of tanks needed; minus one is extra fills on the road.

What if I start at half a tank?

Halve the range input or add a stop. This form assumes a full tank at kilometre 0.

Does CNG have fewer pumps?

Often yes on some corridors. Type a shorter range if CNG stations are sparse, even if the cylinder “could” do 400 km.
