2-minute explanation
A truck may earn revenue on its outward leg but still lose money when the empty return, fuel, tolls, driver, maintenance and allocated fixed costs are included. This tool computes one round-trip estimate with separate outward and backhaul tonnage, not an imaginary market freight quote. Use the fields to model your own historical or contracted facts, and review the detailed bridge rather than relying on one headline result.
Why backhaul economics matter
Outbound profitability can be misleading when an owner-operator or fleet manager looks at only the kilometres carrying booked goods. A return leg with little or no billed load still burns fuel, wears tyres and keeps the vehicle unavailable for other routes. Round-trip cost should be compared with revenue earned on both legs, using genuinely attainable backhaul loads rather than assumed full utilization.
Core calculation method
Round-trip kilometres = two × one-way kilometres. Diesel litres = total kilometres ÷ achieved fuel efficiency. Fuel expense equals diesel litres × diesel price. Add both-leg tolls, driver/helper pay, repairs per kilometre, tyre allowance per kilometre, the trip allocation of fixed costs, loading charges and other incremental charges. Outbound revenue is outbound tonnes × contracted outbound ₹ per tonne; return revenue uses return tonnes × the entered return rate.
Profit and break-even interpretation
Profit or loss equals both-leg freight receipts before taxes minus all included trip costs. Round-trip tonne-kilometres are one-way kilometres multiplied by the sum of paid outward and return tonnes. Utilisation is paid tonne-leg capacity used divided by twice the payload capacity: (outward tonnes + return tonnes) ÷ (2 × rated payload). Break-even outbound freight per tonne is (total trip cost − return freight revenue) ÷ outward tonnes, and is unavailable if the outward load is zero; it may be negative when backhaul revenue alone exceeds cost.
Worked route example
Take a 350-km one-way route, 15-tonne payload, 10 tonnes outbound at ₹1,200 per tonne and 4 tonnes back at ₹1,000 per tonne. Total freight income is ₹16,000. At 4 km/litre and ₹90/litre, fuel is 175 litres or ₹15,750 on the 700-km round trip. The remaining cost inputs are ₹2,200 tolls, ₹2,500 driver, ₹2,100 repairs, ₹1,050 tyres, ₹1,500 allocated fixed cost, ₹1,050 handling and ₹300 other costs. Trip cost is ₹26,450 and the loss is ₹10,450. The example highlights why sales per ton alone are insufficient.
Cost accounting and India-specific controls
ICMAI CAS-5 discusses the identification and equalisation of transportation cost and emphasises separate records of fuel, staff, tyres, vehicle maintenance, insurance, distance, tonnage and transport recoveries. This managerial trip model does not itself allocate inventory freight, classify an inward versus outward cost, determine GST liability, test e-way bill compliance or set fuel prices. Use actual fleet records and current contractual allocations for those matters.
Sensitivity analysis and avoidable errors
Test a zero-backhaul scenario, lower km/litre in hills or traffic, additional tolls, more detention time and uncertain driver allowances. Payload represents the vehicle and permit-specific safe capacity, not the theoretical body volume. Do not enter kilometres for only the loaded leg and assume the vehicle magically returns. The model does not net off freight brokerage, financing costs or depreciation unless they are explicitly entered among allocated or other costs.
Frequently asked questions
Why can the trip lose money with 100% outward loading?
Because backhaul may be empty and unavoidable round-trip costs can exceed outbound receipts.
Does the tool provide legal vehicle loading limits?
No. Enter payload limits applicable to your vehicle, cargo, permits and route.
Should toll costs include both directions?
Yes. The default model includes the full round trip.
Can it automatically calculate GST or TDS?
No. Tax treatment depends on transporter and transaction facts; this model is pre-tax.
