Thinking about chartering a vessel instead of buying one outright? Before you commit, it’s critical to understand how many days your charter must run, and at what rate, just to break even. Fuel, crew, insurance, and lease payments all add up.
Use this guide to get a realistic view of when your charter operation becomes profitable and whether it’s the right move for your strategy.
Break-Even Charter Rate Calculator
Plug in your monthly charter fee, daily operating expenses, expected working days, and today’s fuel price. The calculator will return your minimum viable daily rate (or how many chartered days you need at your planned rate) to hit zero profit/loss.
- Monthly charter hire (or lease payment)
- Average daily OPEX (crew, insurance, maintenance)
- Fuel burn and price (or lump-sum fuel cost)
- Planned charter days vs. off-hire/port days
- Any extras: broker fees, financing, compliance costs
Enter the numbers, hit calculate, and adjust scenarios (fuel spikes, fewer sailing days, higher hire) to see how quickly your margin moves.
