Buy vs Charter vs Lease a Ship Calculator
Compare three ways to secure vessel capacity on the same planning horizon. Measure present-value cost, annual equivalent cost, cost per required vessel day, upfront capital, financing exposure, residual value, break-even hire rates and the assumptions most likely to flip the decision.

Advanced keeps the three structures economically comparable while exposing the assumptions that often reverse the answer.Remaining purchase debt is settled at exit. A lease buyout is modeled separately from any vessel value received with the purchase option.Financial Comparison Basis

Use recurring vessel costs paid by the owner. Voyage expenses are excluded from all three alternatives unless they genuinely differ and you intentionally add them elsewhere.

Commercial / financial limitation: This is a cash-economic screening model, not legal, tax, accounting, investment or financing advice. Charterparty obligations, off-hire, redelivery condition, drydock allocation, commissions, covenants, balloon structures, tax depreciation, IFRS/GAAP lease accounting, opportunity earnings, vessel obsolescence and actual sale value can materially change the result.
