Marine Fuel Range Calculator
Calculate fuel per nautical mile, usable tank volume, arithmetic range and fuel for a supplied distance.
A QUICK WALKTHROUGH
How to use this tool
- Enter your positive measured burn rate and constant speed, plus tank volume.
- Enter your own reserve percentage and distance. No reserve is recommended.
- Calculate, then copy or download the fuel report.
Formula and units
L/nmi = burn (L/h) ÷ speed (kn). Usable L = tank L × (1 − reserve%/100). Range nmi = usable L ÷ L/nmi. Required L = distance nmi × L/nmi.
Scope
Constant burn and speed arithmetic only. Your reserve is not a safety recommendation. Results exclude wind, tide, currents, changing load and port risks; required fuel does not add reserve or establish passage safety.

GOOD TO KNOW
Common questions
Does the range establish a safe passage?
No. It only uses your constant inputs and reserve percentage, without evaluating conditions or fuel sufficiency.
