How the diesel cost calculation works

Monthly diesel litres = number of vehicles × kilometres per vehicle ÷ mileage in km/L. Monthly spend = litres × diesel price. Diesel cost per kilometre = price per litre ÷ mileage.

For example, 25 vehicles travelling 6,000 km each at 3.5 km/L need about 42,857 litres. At ₹90/L, the estimated diesel spend is ₹38,57,143 for the month, or ₹25.71 per kilometre. These are example inputs, not a forecast for your fleet.

Use a measured mileage for the route and load you are planning. If vehicle types or operating conditions differ, calculate each group separately. The result covers diesel only; driver pay, tolls, maintenance and other operating costs are additional.
