Binance uses Margin Level to evaluate the risk level of your Margin account, and Borrow Margin Level and Transfer-out Margin Level to evaluate the borrow and transfer ability of your Cross Margin Account respectively.

1. Margin Level of Cross Margin Classic

Margin Level of Cross Margin Classic Account = Total Asset Value of Cross Margin Account / (Total Liabilities + Outstanding Interest), where:

  • Total Asset Value of Cross Margin Account = Current Total Market Value of All Digital Assets in Cross Margin Account
  • Total Liabilities = Current Total Market Value of All Outstanding Margin Loans in Cross Margin Account
  • Outstanding Interest = Amount of Each Margin Loan * Loan Time (in hours, at the time of the calculation) * Hourly Interest Rate - Deduction/Paid Interest

Your Margin Level is a key risk metric for your margin account. If it falls below a certain threshold, it will trigger margin calls and liquidations.

Please note that asset and liability values are calculated in BTC.

2. Borrow Margin Level 

Borrow Margin Level determines the borrow ability of your Cross Margin account. It is calculated by the Collateral Value, the total value of all assets in your Cross Margin account in USDT. Collateral Value also takes into account each token’s respective Collateral Ratios, which is the percentage at which each asset is valued, and the Token's Index Price. For more details on the Collateral Ratio for each asset, please refer to the Margin Data page. For more details on the Mark Price, please refer to Mark Price.

Borrow Margin Level of Cross Margin Classic Account = Collateral Value / (Total Liabilities + Outstanding Interest), where:

  • Collateral Value = ∑ Net Asset Value of net positive positions (haircuts and index price applied) + 100% * ∑ (Total Liabilities (mark price applied) + Outstanding Interest) of tokens with net positive positions + 100% * ∑ Asset Value (mark price applied) of net negative positions (where assets > 0)
    • Net Asset Value of positive positions (haircuts and mark price applied): For tokens with assets (where assets > liabilities+interest), apply haircuts & mark price for each token after calculating their net asset values (asset - liabilities+interest) and aggregate.
    • (Total Liabilities (mark price applied) + Outstanding Interest) of tokens with net positive positions: For tokens with assets (where assets > liabilities+interest), aggregate the sum of liabilities (mark price applied) and interest. Please note that haircuts are not applied when aggregating the token asset value equivalent to its debt portion. Since 100% of asset value is recognized for this portion, collateral value calculations are to the advantage of users.
    • Asset Value of net negative positions (where assets > 0): For tokens with assets (where assets < liabilities+interest), aggregate the sum of these assets, without applying haircuts.
  • Total Liabilities = Current Total Market Value of All Outstanding Margin Loans in Cross Margin Account (mark price applied)
  • Outstanding Interest = Amount of Each Margin Loan * Loan Time (in hours, at the time of the calculation) * Hourly Interest Rate - Interest Paid

3. Transfer-out Margin Level

Transfer-out Margin Level determines the maximum amount you can withdraw from your Cross Margin account. It is calculated by the Collateral Value, the total value of all assets in your Cross Margin account in USDT. Collateral Value also takes into account each token’s respective Collateral Ratios, which is the percentage at which each asset is valued and the Token's Index Price. For more details on the Collateral Ratio for each asset, please refer to the Margin Data page. For more details on the Index Price, please refer to Index Price.

Borrow Collateral Margin Level of Cross Margin Classic Account = Collateral Value / (Total Liabilities + Outstanding Interest), where:

  • Collateral Value = ∑ Net Asset Value of net positive positions (haircuts and index price applied) + 100% * ∑ (Total Liabilities (index price applied) + Outstanding Interest) of tokens with net positive positions + 100% * ∑ Asset Value (index price applied) of net negative positions (where assets > 0)
    • Net Asset Value of positive positions (haircuts and index price applied): For tokens with assets (where assets > liabilities+interest), apply haircuts & index price for each token after calculating their net asset values (asset - liabilities+interest) and aggregate.
    • (Total Liabilities (index price applied) + Outstanding Interest) of tokens with net positive positions: For tokens with assets (where assets > liabilities+interest), aggregate the sum of liabilities (index price applied) and interest. Please note that haircuts are not applied when aggregating the token asset value equivalent to its debt portion. Since 100% of asset value is recognized for this portion, collateral value calculations are to the advantage of users. 
    • Asset Value of net negative positions (where assets > 0): For tokens with assets (where assets < liabilities+interest), aggregate the sum of these assets, without applying haircuts.
  • Total Liabilities = Current Total Market Value of All Outstanding Margin Loans in Cross Margin Account (mark price applied)
  • Outstanding Interest = Amount of Each Margin Loan * Loan Time (in hours, at the time of the calculation) * Hourly Interest Rate - Interest Paid

*Please be noted that both Borrow Margin Level and Transfer-out Margin Level are calculated by Collateral Value / Debt Value. However, the collateral ratios and the prices they use are separate. 

4. Different Margin Levels and their functions

5. Calculation Examples

Assume the margin parameters for BTC and ETH are as follows. And assume there’s no interest charged. 

 Borrow Collateral Ratio Transfer-out Collateral RatioMax Mark PriceMin Mark Price
BTC99.9%99.9%80,50080,200
ETH95%95%2,2002,180

Scenario: 

The user is holding 0.1 BTC and 1 ETH as collateral. Use Cross Margin 5x as an example, user’s BTC maximum borrow quantity would be: 

(BTC asset value + USDT asset value + BTC max borrow value) / (BTC max borrow value) = 1.25 (max borrow bar for Cross Margin 5x) 

-> (0.1 * 80,500 * 99.9% + 1 * 2,180 * 95% + BTC max borrow qty * 80,500) / (BTC max borrow qty * 80,500) = 1.25

-> BTC max borrow qty = 0.5025. 

Please note: 

1. Collateral Ratio applies to net collateral only.

2. Max Mark Price applies to debt tokens, and Min Mark Price applies to all the other tokens.
