Debt vs Equity
Why Borrowing Money Can Be Smarter Than Giving Away Your Company
The moment a founder sells a share of their company, they have given away a piece of every future dollar that company will ever make.
The Idea
When a company needs capital, it faces a fork in the road: borrow money (debt) or sell a stake (equity). On the surface, debt looks riskier — you owe fixed repayments regardless of how business is going. Equity looks softer — investors only get paid if you succeed. But this framing inverts the real calculus. Debt is expensive in the short term and cheap in the long term. Equity is cheap upfront and extraordinarily expensive over time. When you take on debt, you pay interest and eventually retire the obligation entirely. The lender has no claim on your future profits, your exit, or your upside. When you sell equity, you're not borrowing a sum — you're permanently transferring a fraction of everything the company ever becomes. There's also a tax dimension that tilts the scales further. In most jurisdictions, interest payments on debt are tax-deductible. Dividends paid to shareholders are not. This asymmetry is sometimes called the 'debt tax shield,' and it means governments are quietly subsidising companies that borrow. The deeper tension is about control. Shareholders — especially large institutional ones or venture capitalists — come with opinions, board seats, and veto rights. Lenders, by contrast, largely stay out of your business as long as repayments arrive on time. The tradeoff isn't just financial. It's about who gets to decide where the company goes next.
In the World
In the early 2010s, Apple was sitting on one of the largest cash piles in corporate history — tens of billions held largely outside the United States. Repatriating that cash to return it to shareholders would have triggered a substantial tax bill. So Apple did something that puzzled many observers at the time: it borrowed money. The company issued corporate bonds — essentially taking on debt — to fund share buybacks and dividends, even though it was, technically, one of the richest companies on the planet. The logic was elegant and entirely deliberate. Borrowing was cheaper than the tax cost of bringing its own money home. The interest payments were deductible. And the debt markets were offering Apple rates so low they barely registered as a cost at all, partly because lenders considered Apple as close to a sure thing as corporate borrowers come. This was the debt tax shield in action at an almost theatrical scale. Apple wasn't borrowing because it was desperate — it was borrowing because the structure of the tax code made debt, in this specific configuration, the rational choice. Critics called it financial engineering. Defenders called it fiduciary responsibility. The episode revealed something important: the choice between debt and equity is never purely about access to capital. It's a strategic decision shaped by tax law, investor relations, control, and the cost of money at a particular moment in time.
Why It Matters
You may never run a company, but the debt-versus-equity logic surfaces in decisions closer to home than you might think. When someone takes a personal loan to invest in a business rather than taking on a partner, they're choosing debt over equity. When a small business owner gives a friend a stake in exchange for startup help rather than agreeing on a repayment schedule, they've made an equity decision — often without fully pricing what they've parted with. More broadly, understanding this distinction changes how you read the news. When a company loads up on debt ahead of a buyout, or when a startup raises a funding round at a lower valuation than its last one, the debt-equity framework gives you a lens that most casual observers lack. The real insight is this: capital always has a cost, even when it doesn't feel like it. Equity that requires no monthly payments isn't free — its cost is just deferred and denominated in ownership rather than interest. Recognising that hidden price is one of the more useful habits of financial thinking you can develop.
A Question to Ponder
If giving away ownership is so expensive in the long run, why do so many founders choose equity funding over debt — and what does that reveal about what they actually believe about their own company's future?
