Moomoo charges as little as 6.8% on margin balances up to $25,000, with no subscription required. You need at least $2,000 in the account to borrow, you can borrow up to half the cost of a stock purchase, and you must keep at least 25% equity to avoid a margin call.
Below: every rate tier, what borrowing actually costs in dollars, a worked margin-call example, and how to turn margin on.
What is Margin Trading on Moomoo?
Margin trading involves using the cash and marginable securities already in your account as collateral for a loan from Moomoo Financial Inc. This loan is used to increase your Buying Power—allowing you to buy more stocks than your cash balance alone would permit.
- The Loan: The money you borrow is called a margin loan, and you must pay interest on it.
- The Collateral: The stocks you buy (and any existing marginable assets) act as collateral for the loan.
- Leverage: The ability to invest more than you have, often up to 2x your cash deposit (50% initial margin requirement).
Moomoo's Margin Requirements and Rates
Moomoo aims to be competitive with its margin pricing and clearly defines its account minimums.
Account Minimums
The key threshold you must meet to use margin on Moomoo is set by regulatory bodies (FINRA):
| Requirement | Amount (US Accounts) | Note |
| Minimum Net Asset | $2,000 USD | Your account's total value (cash + securities) must be at least $2,000 to initiate margin borrowing. |
| Initial Margin | Typically 50% | When you buy a new stock, you must use at least 50% of your own funds for the purchase, borrowing no more than 50% from Moomoo (standard Reg T requirement). |
| Maintenance Margin | 25% (FINRA Minimum) | This is the minimum equity you must maintain in your account to keep your position open and avoid a Margin Call. Moomoo, like other brokers, may set a higher requirement for specific, volatile stocks. |
Margin Interest Rates
Moomoo offers tiered margin rates, meaning the interest rate you pay depends on the size of your margin loan (your debit balance).
- Lowest Tier: Moomoo offers margin interest rates as low as 6.8% on debit balances up to $25,000.
- Tiered Structure: The rate generally decreases as the size of your borrowed amount increases. This is competitive with and often lower than many established brokers.
Important Note: Moomoo's margin interest rates are subject to change without notice in response to changes in the prevailing market interest rates (like the Fed rate). Always check the latest rates on the Moomoo website before trading.
How Moomoo's rate compares across the market
Moomoo advertises "as low as 6.8%" against a table of large incumbents, which makes the rate look exceptional. Widen the comparison and it is good rather than exceptional — two brokers are cheaper, and one of them by a wide margin. Rates below are the entry tier each broker charges a small borrower, which is the number that matters if you are borrowing a few thousand dollars rather than a few million:
| BROKER | ENTRY RATE | APPLIES TO | SOURCE AND DATE |
|---|---|---|---|
| Robinhood | 5% | Up to $50,000 | Published rate table, Dec 2025 |
| M1 Finance | 5.65% | Up to 50% of portfolio | M1 help centre, 2 Feb 2026 |
| Interactive Brokers Lite | 6.14% | Introductory tier | Per published comparison, 17 Dec 2025 |
| Moomoo | 6.8% | Up to $25,000 | Moomoo pricing page |
| Webull | 8.74% | Introductory tier | Collected Feb 2025 — verify current |
| Fidelity | 11.825% | Under $25,000 | Base 10.575%, eff. 12 Dec 2025 |
| Charles Schwab | 11.825% | Under $25,000 | Base 10.00%, eff. 12 Dec 2025 |
| E*TRADE | 12.45% | Introductory tier | Per published comparison, Dec 2025 |
Three things that table makes obvious. Robinhood is less than half the cost of Fidelity or Schwab for a small borrower, which is the single biggest spread on the page. Fidelity and Schwab charge identical effective rates at every tier despite different base rates, so margin pricing is not a way to choose between them. And the discount brokers cluster at 5% to 7% while the incumbents cluster near 12%, a gap that has nothing to do with the Fed and everything to do with who they are competing for.
Every figure here is variable and moves with the federal funds rate. The dates are the point — check the current number on the broker's own page before you borrow, because a table like this is out of date the moment the Fed moves.
6.80% is among the lowest published retail rates. Margin still multiplies losses as readily as gains. Open a Moomoo account.
How to Start Margin Trading on Moomoo
The process for activating margin trading on Moomoo is often simpler than with many other brokers, as the margin feature is typically enabled by default when you open a standard individual brokerage account and meet the minimum deposit.
- Open and Fund Your Account: Complete the standard Moomoo application process. Ensure your net assets are at least $2,000 USD.
- Margin is Default: Your Moomoo Financial Inc. brokerage account is typically set up as a margin account by default once you meet the $2,000 minimum.
- Check Your Status: You can confirm your status and find your current requirements by navigating to the "Me" or "Account" sections within the Moomoo app.
- Trade: Margin is used automatically if your own cash is insufficient to cover a trade. When you place a buy order for a marginable stock that exceeds your cash balance, Moomoo lends you the difference, and you begin accruing interest.
Understanding the Risks
It is important to understand that margin trading is not suitable for everyone and involves amplified risk.
| Risk Factor | Simple Explanation | Moomoo's Defense Tool |
| Amplified Losses | Since you are leveraging your position, any market drop is magnified. You can lose more than your initial investment and still owe the interest on the loan. | Trade Preview Feature: Allows you to estimate the exact impact a trade will have on your margin balance before you execute the order. |
| Margin Call | If your account equity falls below the Maintenance Margin requirement, Moomoo will issue a "margin call," demanding you deposit immediate cash or sell assets to restore your equity level. | Real-time Risk Monitoring: Moomoo provides continuous updates and alerts regarding your margin balance and buying power to help you proactively manage risk. |
| Forced Liquidation | If you fail to meet a margin call promptly, Moomoo has the right to sell some or all of your securities (even at a loss) without consulting you to repay the loan. | Soft Edge Margin/Liquidity Indicators: The app provides clear indicators to help you avoid falling into this extreme risk state. |
| Interest Costs | Interest is calculated daily on the borrowed amount. These costs can erode profits even on successful trades and increase your losses on poor-performing investments. | Low Margin Rates: Moomoo tries to mitigate this with low initial margin rates compared to many competing brokers. |
Conclusion: Margin is a Tool, Not a Strategy
Margin trading on Moomoo offers a compelling way to increase your buying power, supported by competitive interest rates (starting as low as 6.8%) and a straightforward sign-up process that requires a minimum of $2,000 in net assets.
Moomoo provides the data and tools, like real-time risk monitoring and trade preview, to help you manage leverage responsibly. However, it is essential to remember that margin is a financial tool that magnifies both gains and losses.
For a new investor, treat margin trading with extreme caution. Never risk money you cannot afford to lose, and only use margin to supplement a solid, well-researched investing strategy. Understand the maintenance margin and always keep sufficient excess equity to avoid a devastating margin call.
