The margin account requirements are as follows:

  • An investor interested in opening a loan account must first deposit $2000 or 100% cash equivalents of the stock they wish to purchase.
  • A brokerage loan account has a 50% borrowing limit—50% of the stock value—known as the initial margin requirement or restriction.
  • When an investor buys on margin, the brokerage attaches a maintenance margin to the account—typically 25%. But this maintenance margin varies from firm to firm; it can even go up to 40% of the security’s value.
  • A margin call is issued if an investor falls below the minimum margin. Similarly, lack of funds and interest repayment defaults also raise margin calls.
  • A brokerage firm charges a yearly interest rate on a loan offered to the investor. Typically interests on margin loans range between 2% and 4%. But it may vary depending on the particular firm. Interests on these loans are called margin interest rates.


Let us look at some margin account examples to understand the concept better.

Example #1

Phil buys a stock for $90. Soon, the stock price rises to $135. If Phil sells the stock, he will earn a 50% return and receive the full payment.

Now, let us assume that Phil bought the stock on margin. In this case, Phil only paid $45 in cash, he borrowed the remaining $45 from a broker. In such a scenario, Phil will make a 100% return when he sells the stock.

To be precise, Phil also owes the broker an interest, so his actual returns are a little less than 100%.

Let us assume that the same stock’s price declines from $90 to $45. If Phil had bought the stock with cash, he would lose only 50% of his money. But Phil bought the stock on margin, so he loses more than 100% of his money. On top of the investment, Phil also owes interest to the broker.

Example #2

Bybit is a Chinese derivatives brokerage firm in Singapore. In July 2022, Bybit announced the launch of a unified margin account—for eligible investors.

Bybit claimed to unveil a new structure. This new feature allows investors to use all their assets as collateral to procure investment loans.
