Fuel Cost Calculator

Diesel is one of the few costs contractors track closely — and still one of the easiest to lose to inefficiency and pilferage.

Why Contractors Lose Money Here

Fuel consumption rate (litres per running hour) is one of the most reliable early indicators of equipment health and, when it drifts without explanation, of fuel pilferage on site. Consumption creeps up from clogged air/fuel filters, injector wear, excessive idling while "waiting for material," and operators running engines to power auxiliary equipment. Diesel is usually tracked as a total monthly spend, not reconciled against logged running hours per machine — without that reconciliation, a consumption creep looks identical to "just more work done this month."

Real Site Example

A machine running 220 hours/month at 5.2 L/hr instead of its own known-good baseline of 4.5 L/hr burns roughly 1,850 extra litres a year — at ₹92/litre, that is over ₹1.7 lakh in avoidable fuel cost on a single asset.

Professional Best Practices

Disciplined operations log fuel filled against hours run per machine daily, flag any consumption rate more than 10% above the machine's own baseline, and schedule filter/injector servicing on a fixed interval rather than reactively.

Engineering Checklist

  • Log fuel filled against hours run daily, per machine
  • Record each machine's own baseline consumption (from spec sheet or a known-good period) rather than relying on a generic industry figure
  • Set an operator policy to shut off engines during extended waits
  • Schedule filter/injector servicing on a fixed interval, not reactively
  • Investigate a sudden consumption jump (likely pilferage) differently from a gradual creep (likely maintenance)

How Experienced Contractors Handle This

Disciplined operations log fuel filled against hours run per machine daily, flag any consumption rate more than 10% above the machine's own baseline, and schedule filter/injector servicing on a fixed interval rather than reactively.

Common Mistakes
Patterns we see repeatedly across Indian construction sites — worth checking against your own process.
1
Tracking diesel as a total monthly spend instead of reconciling against logged running hours
A consumption creep looks identical to "just more work done this month" without hour-level reconciliation.
2
Comparing consumption against a generic industry figure instead of the machine's own history
Different machines of the same type can have genuinely different healthy baselines depending on age and condition — a generic figure produces false alarms or false confidence either way.
3
Servicing filters and injectors reactively instead of on a fixed schedule
Consumption creeps up gradually from wear that a fixed maintenance interval would have prevented.
4
Not logging fuel filled against hours run daily per machine
Without this pairing, there is no way to distinguish engine inefficiency from pilferage when consumption looks high.
How Rebota Automates This

Rebota's Equipment Monitoring module tracks fuel entries against running hours per asset, flagging consumption drift against that machine's own history automatically instead of waiting for the monthly diesel bill to look "high."

Frequently Asked Questions
Why does this calculator ask for MY baseline instead of showing an industry benchmark?
We do not have a verified, cited source for fuel consumption benchmarks by equipment type — rather than invent one, we compare your machine against its own known-good rate, which you provide from the spec sheet or past logs.
How can I tell if fuel loss is pilferage or engine inefficiency?
A sudden jump in consumption with no change in workload usually points to pilferage; a gradual creep over weeks more often indicates filter/injector wear needing service.
What if I don't know my machine's baseline consumption?
Leave it at 0 — the calculator will still show idle and suspected-pilferage costs, which don't require a baseline, but will not judge your raw consumption rate as good or bad without one.
Where does the 0.6 L/hr idle consumption figure come from?
It is a Rebota engineering estimate for a typical mid-size diesel engine at idle, not a manufacturer-specific or externally cited figure — disclosed here rather than presented as a benchmark.
