Debt and Equity

What is Debt?

Debt means borrowing money — and promising to pay it back with interest.

In business or investing:

  • A company takes debt (like loans or bonds) to raise money.
  • The lender gets interest payments and the money back later.
  • The company must repay the debt, no matter how business goes.

Example:

  • Apple issues a bond to raise $1 billion.
  • Investors (lenders) give Apple money.
  • Apple pays interest every year and repays the $1B after ~10 years.

Key points:

  • Debt is less risky for the investor, but must be repaid.
  • It gives no ownership in the company.

What is Equity?

Equity means ownership in a company.

In business or investing:

  • When you buy stock, you own a piece of the company.
  • Your gains come from price increases and dividends (if paid).
  • There is no promise to pay you back — returns depend on performance.

Example:

  • You buy Apple stock.
  • If the stock price rises, you profit.
  • If the price falls, you bear the loss.

How Companies Use Both

  • Debt is cheaper than equity (interest is often tax-deductible).
  • But too much debt increases bankruptcy risk.
  • Raising equity dilutes ownership but reduces debt burden.
  • Used for growth, acquisitions, or strengthening the balance sheet.

Investor Takeaways

  • Debt investments (like bonds) are steadier but capped; equity can grow more, with higher risk.
  • Companies balance debt vs. equity to optimize cost of capital and risk.
  • For portfolios, a mix of both can balance risk and return.
