Reconcile entered voyage-use, reserve, price, and budget records without predicting fuel burn or safe range from nominal MPG.
A quick decision brief for this specific tool
Full round-trip distance record, logged or independently planned underway fuel, separate non-cruise and reserve records, current price and entered budget
Voyage-use and onboard fuel targets, purchase-cost target, reserve share and signed budget difference
Reconciles entered fuel and money records; it does not predict burn, choose reserve or calculate safe range from nominal MPG
Choose your path
Reconcile entered voyage-use, reserve, price and budget records without predicting fuel burn or safe range from nominal MPG.
Keep the full route, logged/planned underway use, non-cruise use and reserve visible.
Enter the matched records, current price and budget, then inspect the purchase-target difference.
Sees traceable cost arithmetic without a nominal-MPG burn promise.
Separate consumption assumptions from the independently chosen reserve.
Update the measured/logged basis and current conditions externally before changing the entered records.
Does not treat the reserve share or fuel-per-mile record as universal.
Keep weather, usable capacity, route hazards and safety requirements above budget arithmetic.
Check official forecasts/warnings, vessel condition, reserve policy and float plan externally.
Never uses a favorable budget gap as clearance to depart.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Enter the complete round-trip distance and an underway-fuel amount supported by a log or independent voyage plan for the same vessel, loading, speed, route, and conditions. The tool does not derive fuel use from nominal MPG.
Voyage-use target equals the entered underway record plus the entered non-cruise allowance. The entered reserve remains separately visible, and onboard target is their sum.
The entered onboard target is multiplied by the entered current price and compared with the entered budget. This money check does not approve a route, reserve, tank loading, or departure.
Updated: August 2026
Reconcile a documented voyage-use plan, non-cruise allowance, reserve record, current dock price, and fuel budget before purchasing.
Replace an older underway-fuel record with a better matched log while keeping reserve and non-cruise use traceable.
Use the budget result only after separately confirming usable tank capacity, weather, route, reserve policy, vessel condition, and float plan.
Enter the complete route distance represented by the fuel record. The calculator never doubles or guesses the route.
Cost arithmetic cannot validate actual burn, usable capacity, reserve, route, weather, seaworthiness, or legal requirements. Confirm those externally and monitor fuel underway.
This record check keeps voyage-use fuel, non-cruise allowance, reserve, current price, and budget visible in one auditable calculation. It deliberately avoids nominal-MPG burn and safe-range promises.
