Real tools for
real fuel problems
Every calculator on this page was built to answer a question our customers ask us regularly. We built them as free tools because the best way to help commercial operators is to give them what they need — whether or not they become a FuelGo customer.
If you do need fuel or a tank delivered, we're here 24/7 across all 50 states.

FuelGo's free calculator library is designed for the people who actually manage fuel on the ground — construction site superintendents, fleet managers, facility directors, and equipment rental companies. These tools are built around the real questions our delivery team hears every week from customers across all 50 states.
Every calculation uses industry-standard consumption rates from EPA, EIA, and equipment manufacturer data. Results are estimates — actual consumption varies based on engine age, load conditions, altitude, and ambient temperature — but they're accurate enough for budgeting, planning, and procurement decisions.
Who these tools are for
Built for every commercial fuel user
Construction site managers use the tank size calculator and construction fuel planner to set up their fuel infrastructure before a project starts — avoiding the costly scramble of last-minute emergency deliveries. The generator fuel calculator helps size temporary power systems accurately.
Fleet managers use the DEF consumption calculator to budget fluid costs alongside diesel, and the fuel card comparison to justify switching from card-based purchasing to scheduled on-site delivery — a switch that typically saves 15–30% on total fuel spend once all costs are counted.
Facility managers and data center operators use the generator maintenance checklist to stay NFPA 110 compliant and the generator fuel calculator to size their fuel reserve for extended outages. For critical operations, knowing exactly how long your fuel supply will last is not optional — it's a core part of business continuity planning.
Equipment rental companies frequently link to these tools as a resource for their own customers, helping them size tanks and plan fuel for rented generators and construction equipment. If you run an equipment rental operation and would like to feature these calculators on your own site, contact us — we're happy to discuss embedding options.
