Return on Margin Calculator



Return on Margin (ROM) is a financial metric that assesses the return generated from an investment made with borrowed funds, commonly known as margin. Margin trading allows investors to leverage their positions, potentially amplifying gains but also increasing the risk of losses. The ROM Calculator helps traders determine whether their margin trades are yielding profits or incurring losses.


The formula for calculating Return on Margin is relatively straightforward:

ROM = (Net Profit or Loss / Initial Margin Deposit) × 100


  • Net Profit or Loss: The difference between the final value of the investment and the total cost, including any interest paid on borrowed funds.
  • Initial Margin Deposit: The initial amount of money deposited to open a margin position.

How to Use?

Using a Return on Margin Calculator is a simple process:

  1. Gather the relevant data: To calculate ROM, you need to know the net profit or loss from your margin trade and the initial margin deposit.
  2. Input the data: Enter the net profit or loss and the initial margin deposit into the ROM Calculator.
  3. Calculate ROM: The calculator will then provide you with the ROM percentage, which represents the return on your margin investment.
  4. Interpret the results: A positive ROM indicates that your margin trade has been profitable, while a negative ROM suggests a loss. The higher the ROM percentage, the more profitable your margin trade has been.


Let’s illustrate the concept of Return on Margin with an example:

Suppose you deposit $5,000 as an initial margin to enter a margin trade. After some time, you close the trade, and your net profit from the trade is $1,200.

Using the Return on Margin formula:

ROM = (1,200 / 5,000) × 100 ROM = (0.24) × 100 ROM = 24%

In this example, your Return on Margin is 24%, indicating that you generated a 24% return on your initial margin deposit through the margin trade.


Q1: Is a higher Return on Margin always better?

A1: Not necessarily. While a higher ROM suggests a more profitable margin trade, it also implies higher risk. High returns on margin can result in significant losses if the trade goes against you.

Q2: Can the Return on Margin be negative?

A2: Yes, a negative ROM indicates a loss on the margin trade. It means that the net loss exceeds the initial margin deposit.

Q3: What is a good ROM percentage?

A3: The definition of a “good” ROM percentage varies depending on individual risk tolerance and investment goals. A ROM higher than the cost of borrowing (interest on the margin) may be considered favorable.


The Return on Margin Calculator is a valuable tool for traders looking to assess the profitability of their margin trades. It helps you evaluate whether the use of borrowed funds is contributing to your overall returns or if it’s leading to losses. Remember that while a positive ROM is generally desirable, it’s crucial to manage the risks associated with margin trading and consider your individual financial objectives and risk tolerance. Make informed decisions, and may your margin investments be profitable!
