Funding and cost of capital

Where a company's money comes from and what it costs. These lessons start with the choice between borrowing and owners' money, put a price on each, blend the two into a cost of capital, and end with how profit is returned to owners.

The real example is Apple's fiscal 2025 accounts: its book and market leverage, the rates on its notes, its tax rate, and a payout larger than its free cash flow. Where an input is a judgement, such as a beta or a risk premium, the lesson says so and shows how much the answer moves.
