Generator Run Time Calculator

Estimate how long a generator runs on a full tank at a given load.

About Generator Run Time Calculator

Travel time for Generator Run Time is distance divided by speed, with a small allowance added per stop so the estimate reflects realistic journeys. Planning around the actual time rather than just the distance is what makes a schedule realistic.

Formula

Generator Run Time

Time = distance / speed; stops add a fixed delay each

stops: Each stop adds about a quarter hour

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
