Picking between time charter and buying outright is a cash-flow chess match. Freight cycles, asset values, financing terms, and your route mix all change the math. The right choice compounds returns; the wrong one locks in costs. Below is a fast, visual way to frame the decision before we run numbers in the calculator.
