In this article, you will learn:
The Cross Margin Pro maximum borrow limit is determined by your available margin amount. The maximum borrow amount of each token = Available Margin Amount / Initial Margin Rate of that token. See the examples below on how maximum borrow amounts are calculated.
Note: The illustration below is a purely hypothetical example to demonstrate how Margin Level and Collateral Margin Level are calculated, as well as their impacts, in the Cross Margin Pro mode.
To calculate the maximum amount that can be borrowed for a specific liability coin and the Margin Level in the Cross Margin Pro mode, both the tiered collateral ratio and the Liability Coin Leverage table are required. Suppose the hypothetical collateral ratio and the liability coin maintenance/initial margin rate are as follows. Also, assume that the Interest is zero.
Liability Coin | Tier | Max. Leverage | Liability Value in USDC | Maintenance Margin Rate | Initial Margin Rate |
BTC | 1 | 10x | 0 - 1,000,000 | 2% | 11.12% |
2 | 8x | 1,000,000 - 2,000,000 | 3% | 14.29% | |
3 | 5x | 2,000,000 - 3,000,000 | 4% | 25% | |
4 | 3x | 3,000,000 - 4,000,000 | 5% | 50% | |
USDC | 1 | 10x | 0 - 1,000,000 | 3% | 11.12% |
2 | 8x | 1,000,000 - 2,000,000 | 4% | 14.29% | |
3 | 5x | 2,000,000 - 3,000,000 | 5% | 25% | |
4 | 3x | 3,000,000 - 4,000,000 | 6% | 50% |
Collateral Coin | Tier | Amount | Collateral Ratio |
BTC, USDC | 1 | 0 - 1,000,000 | 1 |
2 | 1,000,000 - 2,000,000 | 0.975 | |
3 | 2,000,000 - 3,000,000 | 0.95 | |
4 | 3,000,000 - 4,000,000 | 0.9 | |
5 | 4,000,000 - 5,000,000 | 0.85 |
Suppose under the current scenario, User A initially has 1 BTC, and has already borrowed 1 BTC.
User A’s Coin Holding | Position | Liability | Index Price |
BTC | 2 | 1 | 10,000 |
USDC | 0 | 0 | 1 |
The below table demonstrates, in the current scenario and after reaching the maximum borrowable amount of USDT, how the Cross Margin Pro mode’s Margin Level, Collateral Margin Level, and maximum borrowable amount in USDT are calculated, as well as their impacts.
Basic Parameters for Further Calculations
Borrow 10,000 USDC | Borrow 89,928 USDC (The Max. Borrowable Amount) | ||
In USDC | ∑Asset | = 2 * 10,000 = 20,000 USDC | = 2 * 10,000 + 79,928 = 99,928 USDC (2 BTC and 79,928 USDC) |
∑Collateral Value | = 2 * 10,000 * 100% = 20,000 USDC | = 2 * 10,000 * 100% + 79,928 * 100% = 99,928 USDC | |
Total Liability | = 10,000 USDC | = 10,000 + 79,928 = 89,928 USDC (1 BTC and 79,928 USDC) | |
∑Net Equity | = 20,000 - 10,000 = 10,000 USDC | = 99,928 - 89,928 = 10,000 USDC | |
∑Initial Margin | = 10,000 * 11.12% = 1,112 USDC | = 10,000 * 11.12% + 79,928 * 11.12% = 10,000 USDC | |
∑Maintenance Margin | = 10,000 * 2% = 200 USDC | = 10,000 * 2% + 79,928 * 3% = 2,597.84 USDC |
Margin Level Calculation
Margin Level | = ∑Net Equity / ∑Maintenance Margin = 10,000 / 200 = 50 | = ∑Net Equity / ∑Maintenance Margin = 10,000 / (10,000 * 2% + 79,928 * 3%) = 3.849 |
Margin Level Health Status | Margin Level > MCR The account is low risk | Margin Level > MCR The account is low risk |
Collateral Margin Level Calculation
Collateral Margin Level | = ∑Collateral Value / Total Liability = 20,000/10,000=2 | = ∑Collateral Value / Total Liability = 99,928 / (10,000 + 79,928) = 1.11 |
Transfer Status | Collateral Margin Level = 2 The user is restricted from transferring funds out of the margin account. | Collateral Margin Level < 2 The user is restricted from transferring funds out of the margin account. |
Max Transfer Out Amount | 0 | 0 |
Convert to Cross Margin Classic (5X) | Yes Collateral Margin Level > 1.25 | No Since ∑Asset/∑Liability = 1.19, Collateral Margin Level < 1.25 |
Available Margin Amount and Borrowable Amount
Available Margin Amount | Available Margin Amount will be displayed at the wallet page. = Max (∑Net Collateral - ∑Initial Margin, 0) = Max (∑Collateral Value - ∑Liability - ∑Initial Margin, 0) = Max ( 20,000 - 10,000 - 1,112, 0) = 8,888 USDC | Available Margin Amount will be displayed at the wallet page. = Max (∑Net Collateral - ∑Initial Margin, 0) = Max (∑Collateral Value - ∑Liability - ∑Initial Margin, 0) =Max (99,928 - 89,928 - 10,000, 0) = 0 USDC |
| Additional BTC max borrowable amount | = Available Margin Amount / Initial Margin Rate = 8,888 / 11.12% = 79,928 USDC With the same asset amount, the borrowable amount is higher than in the Cross Margin Classic mode. | = Available Margin Amount / Initial Margin Rate = 0 |

Total BTC borrow amount is 272.50142857, which falls under Tier 3. ETH borrow amount is 50, also falls under Tier 1) | |
∑Maintenance Margin

Collateral Margin Level Calculation
Collateral Margin Level | = ∑Collateral Value / Total Liability = 1,089,000 / 550,000 = 1.98 | = ∑Collateral Value / Total Liability = 3,217,512.85713 / 2,775,014.2857 = 1.159458 |

| Additional BTC max borrowable amount | 476,255 / 11.12% = 4,282,599, above the Tier 4 borrow range The maximum borrowing amount for BTC is not as straightforward as in Example 1. You may need to attempt 1-2 times to determine the tier in which the maximum borrowing amount falls, in order to reduce the Available Margin Amount to zero. The Cross Margin Pro mode is more capital-efficient than the Cross Margin Classic mode. With the same net equity amount, the borrowable amount in the Cross Margin Pro mode is higher. | 0 |
