Equipment Fuel Estimator

Estimate fuel consumption and cost for construction equipment over a job duration.

Inputs

For estimation purposes only. Terms of Use

Estimate

total fuel cost ($)
Rate
Total hours
Total litres
Cost per day

Formula Used

Total Hours = Hours/Day × Days
Total Litres = Rate (L/hr) × Total Hours
Total Cost = Total Litres × Price/L

Worked Example

A medium excavator (20 L/hr) running 8 hrs/day for 10 days at $1.65/L:

Total Hours = 8 × 10 = 80 hrs
Total Litres = 20 × 80 = 1600 L
Total Cost = 1600 × 1.65 = $2,640

When to Use This Calculator

Use this for project budgeting, equipment cost tracking, or estimating fuel allowances on tender submissions before a job starts.

When Not to Use This Calculator

Actual consumption varies significantly with load, terrain, idle time, and operator habits. For precise cost tracking, use actual fuel logs from equipment telematics where available.

Frequently Asked Questions

Does idle time count toward operating hours?

This calculator assumes active operating hours. Idle time consumption is typically lower (around 30-40% of working rate) and would need separate accounting for full accuracy.

Why do consumption rates vary so much?

Load, terrain, operator technique, and equipment age all significantly affect actual fuel burn. The values shown are typical mid-range estimates for medium-duty operation.
