Buying on margin involves getting a loan from your brokerage and using the money from the loan to invest in more securities than you can buy with your available cash. Through margin buying, investors can amplify their returns — but only if their investments outperform the cost of the loan itself.

When should you buy on margin?

Buying on margin occurs when an investor buys an asset by borrowing the balance from a bank or broker. Buying on margin refers to the initial payment made to the broker for the asset—for example, 10% down and 90% financed. The investor uses the marginable securities in their broker account as collateral.

Can I pay off my margin balance?

Margin interest rates are typically lower than credit cards and unsecured personal loans. And there's no set repayment schedule with a margin loan—monthly interest charges accrue to your account, and you can repay the principal at your convenience.
