How to calculate generator fuel consumption
This calculator finds total generator fuel consumption by multiplying fuel use per hour by total run time.
How the calculation works
Fuel consumption = Fuel use per hour × Run time.
Example
1.2 gallons/hour over 8 hours of runtime: Fuel consumption = 1.2 × 8 = 9.6 gallons.
Frequently asked questions

Let's understand your generator fuel consumption result.
Calculate a result above and this guide will help you interpret it using this calculator's own formula and explanation.
Pro Tips for Generator Fuel Consumption
- Fuel consumption rate varies significantly with generator load — a generator running near its rated capacity burns more fuel per hour than one running lightly loaded.
- Use your specific generator's fuel consumption chart at your expected load level, not just the full-load or no-load figures.
Common Generator Fuel Consumption Mistakes to Avoid
- Using a generator's full-load fuel consumption rate to estimate consumption when it's actually running at partial load, which overstates real fuel use.
