You've probably stared at your bank balance wondering whether to pocket this month's 3 million won in net profit as your own salary or plow it back into advertising. That hesitation has a name. In finance, it's called capital allocation — deciding where the money you've earned should go next. Even companies worth trillions face the same dilemma every year. Today we're opening Nvidia's 10-K, the annual report it files with the U.S. Securities and Exchange Commission, as our textbook. Trace the decisions this company made in front of its own bank balance, and you'll find your business's decisions follow the same grammar.

Every Dollar Earned Has Three Roads to Travel

When a company turns a profit, that money has essentially three places to go. The first is dividends — cash paid out to shareholders, the corporate equivalent of a sole proprietor's owner draw or personal salary. The second is reinvestment: pouring money back into the business through advertising, equipment, or new product development. The third is share buybacks, where a company repurchases its own stock on the open market to lift the value of the shares that remain — a different flavor of returning cash to shareholders than a dividend. This choice lays bare management's read on growth. If leadership believes reinvesting will generate a higher return than the alternatives, the money flows back into the business; if not, it flows out as dividends or buybacks. Follow where the money goes, and you can see how a company is doing the math on its own future.

Profit Made Nvidia's Choice Possible

Nvidia's FY2026 numbers show this choice in action. Revenue came in at $215.9 billion, net income at $120.1 billion — a 55.7% net margin. That's roughly double the 20-35% margins typical of large semiconductor peers. Yet the company pays out almost no dividends. Instead, it channels its $96.7 billion in free cash flow — 80.5% of net income — into share buybacks and capital equipment. The logic behind the buybacks is straightforward: with AI infrastructure demand exploding, management has calculated that directing cash toward the business and its own stock builds more shareholder value than dividends would.

There's another detail worth noting. While revenue grew 3.5x, from $60.9 billion to $215.9 billion, long-term debt actually shrank, from $10.9 billion to $8.5 billion, and the debt-to-equity ratio fell from 0.41x to 0.05x. In other words, Nvidia didn't borrow to fund its growth — it paid for it with earnings. With no interest payments eating into the till, the company gets to decide what to do with every dollar it makes. The margin created the spare cash, and the spare cash created the freedom to choose.

Where the Profit Flows

The diagram below traces where the cash generated by FY2026 revenue ultimately went.

The empty dividend box reflects a calculation: that the expected returns from reinvestment and buybacks outweigh what a dividend would deliver.

Asking the Same Question of Your Own Numbers

Now let's apply this framework to a bank account holding 3 million won in monthly net profit. The first question is reinvestment return: estimate how much next month's profit would grow if you put an extra 1 million won into advertising. If that return beats what you'd earn putting the money elsewhere, this is a moment for reinvestment, not withdrawal. The second question is debt. Nvidia's freedom to choose rests on having almost nothing left to repay. If your business hands its profit straight to monthly loan payments, paying down debt comes before any capital allocation decision. Third, even a solo operator has an equivalent to a share buyback: spending on equipment upgrades, brand refreshes, or automating repetitive tasks — money that doesn't generate revenue immediately but raises the value of the business itself.

One Thing to Try Today

Take last month's net profit and sketch a simple three-line table: money withdrawn, money reinvested in the business, and money spent to raise the business's own value. The ratio between those three lines is your own growth judgment about your business, written out in numbers. Just as Nvidia's buyback decision ultimately came down to a calculation about reinvestment returns, filling out this table will reveal, in hard numbers, what return you believe your business can generate. Reading financial statements starts with someone else's company — and ends with sorting out the hesitation in front of your own bank balance.
