Margin rates refer to the interest rate charged by brokers when traders or investors borrow money to buy securities (such as stocks or bonds) on margin.

Essentially, buying on margin allows investors to leverage their purchasing power by using borrowed funds to increase their potential investment return.

The margin rate is important because it determines the cost of the borrowed funds, directly affecting the overall profitability of the investment.

Margin Rates Expressed as a Percentage

Margin rates are expressed as a percentage and can vary significantly between brokerage firms, based on factors such as the amount borrowed (with higher loan amounts often receiving lower rates), the brokerage’s policies, and prevailing market interest rates.

Additionally, the margin rate can be influenced by the trader/investor’s account balance and creditworthiness.

 

Costs & Benefits of Margins
