What Is Margin Level and How Do You Calculate It?

Margin level is a risk-management indicator that helps you understand what influence the currently opened positions have on your account.

The margin level in your options trading account is a formula that tells you how much of your funds are available to open new trades. The higher your margin level percentage, the more funds are available to trade. If the margin level drops too low, you could receive a margin call.

What Is Margin Level?

Your margin level percentage is a measure of the relationship between the equity in your trading account and how much margin is in use. The margin level calculation is expressed as a percentage: (equity / margin) x 100.

It’s helpful to think of margin level as a reading of your trading account’s health. A margin level percentage of 0% means you have no open positions. A margin level of 100% means that the amount of a portfolio’s equity and used margin are equal. Equity is the cash available to trade, plus any unrealized profits and losses on open positions. Many brokers will not allow investors to make new opening trades when the margin level on their options trading account is 100% or less.

When margin level falls below 100%, the broker might issue a margin call. Unless the market moves back in your favor, you must deposit more funds (or assets) into your account when you are hit with a margin call. You can also satisfy a margin call by exiting your current holdings.

The margin level percentage depends on various factors. The volume of your positions and their potential effect on the market can affect your margin level calculation; as can the amount of leverage you use.

What Does Margin Level Really Do?

To understand what margin level means, it’s important first to grasp the concept of margin in options trading.

Margin is the amount of cash or securities a trader must deposit in their account before being able to write (or sell) options. You can think of it as a good faith deposit or a form of collateral.

The Federal Reserve Board’s Reg T sets margin requirements. Margin works differently in options and futures accounts than in stock trading accounts. Margin debt in stock trading refers to the amount of borrowed funds used to buy new shares. This is also referred to as using leverage.

The margin level calculation tells you how much of your funds are available to use for new opening trades. The higher your margin level, the more “free margin” you have. Free margin is the amount of money available to place new trades. Margin is composed of “used” and “free” amounts. Used margin is the aggregate of all the required margin on your existing positions. Free margin, on the other hand, is the difference between equity and used margin.

Margin level also can inform you of how much wiggle room you have in your options trading account, or other types of accounts. A very high margin level percentage means you have a large amount of equity relative to the total amount of required margin. A low margin level calculation tells you that your account might not be far from getting a margin call.

Calculating Margin Level

Calculating margin level is straightforward: Divide the equity by the amount of used margin; then multiple that quotient by 100:

Margin level = (equity / margin) x 100

If you don’t have any open positions, then your margin level calculation will be zero. This can be confusing because usually, a low margin level means your account might be at risk for a margin call. A 0% margin level is the safest and lowest-risk margin level you can have, because in that scenario, you’d have no open positions.

Margin level = (equity / margin) x 100

Margin Level Example

Suppose you deposit $10,000 into your account. Before you make any trades, your margin level is 0%, as you don’t have any used margin (the divisor in the earlier-mentioned equation is zero). Your first buy is a call option on shares of XYZ stock, and you pay a $5,000 premium. Your margin level calculation is now 200% ($10,000 / $5,000 = 200%).

Now let’s say you open another $5,000 options position. Your margin level declines to 100% ($10,000 / $10,000 = 100%). We will assume that is the broker’s minimum margin level before a margin call is issued. Later, we’ll detail what happens if your margin level falls below the critical 100% threshold.

Why Understanding Margin Level Is Important

The margin level percentage is important, as brokers use this figure to determine whether you can open new positions. Many brokerage firms set a minimum margin percentage at 100%. So if your margin percentage drops below that threshold, then you will encounter a margin call — or even a forced liquidation — on one or more of your open trades. If you want to take on new positions, then you’d be forced to sell an existing holding or add more funds to your account.

Margin Level Below 100%

Taking our earlier example a step further, If the market moves against you, and your option values fall to $9,000 on the market, your margin level calculation would decline to below the minimum margin level ($9,000 / $10,000 = 90%). The broker then would issue a margin call. You have two choices: either sell an existing position or deposit more assets into the account. If you do not act promptly, the broker can sell one of your positions automatically.

Your margin level could fall below 100% based on small moves in the assets you own. Broad market conditions, like volatility, also could affect your account negatively. In an extreme example, Silver Thursday rocked the silver trading market and caused long futures and options positions on silver to suffer severe losses. In turn, this triggered an onslaught of margin calls in the precious metals markets. The moral of the story: It’s important to manage risks carefully when using leverage.

If you’re interested in trading on margin, or just want to know more about it, you’ll need to understand the difference between marginable and non-marginable securities.
