1. 導言
你係投資者想用融資借錢放大回報，但係唔知槓桿後嘅 實際報酬率（ROE） 同 風險 有幾大？又或者你擔心市場下跌時會唔會 被追繳保證金（Margin Call） 甚至 強制平倉（Liquidation）？槓桿效應（Leverage Effect）與保證金（Margin） 就係決定「借錢投資值唔值得」嘅關鍵。我哋嘅免費槓桿計算機幫你輸入 自有資金、借貸金額、融資利率與預期報酬率，即時計算 槓桿後淨報酬率（ROE）、損益平衡點（Break-Even Return），仲會自動評估 槓桿倍數 同 強制平倉風險。所有運算喺瀏覽器入面完成，數據唔會離開你嘅裝置，私隱 100% 安全。
2. 背景與概念解釋
槓桿效應（Leverage Effect）與保證金（Margin） 係金融投資中放大收益同時亦放大虧損嘅雙刃劍。主要概念包括：
- 槓桿倍數（Leverage Multiplier）： 總資產 ÷ 自有資金。槓桿 2x 表示每 $1 本金控制 $2 資產。
- 槓桿後股東權益報酬率（Leveraged ROE）： 扣除利息成本後，本金獲得嘅淨報酬率。公式：ROE = (資產報酬率 × 總資產 - 利息支出) ÷ 本金。
- 損益平衡報酬率（Break-Even Return）： 標的資產須達到嘅最低報酬率，以完全覆蓋借貸利息成本。
- 維持保證金率（Maintenance Margin）： 融資帳戶中自有資金佔總資產嘅最低比例，低於此比例將觸發追繳通知。
- 強制平倉臨界跌幅（Margin Call Drop）： 標的資產價格下跌多少百分比會觸發強制平倉。
- 融資成本（Interest Cost）： 借貸資金所需支付嘅利息，直接影響槓桿策略嘅淨回報。
3. 實際應用場景
- 股票融資（Margin Trading）： 評估融資買股票嘅收益放大倍數與追加保證金風險。
- 期貨保證金交易： 計算期貨合約嘅保證金要求與強平價格。
- 房地產槓桿投資： 評估按揭貸款買樓嘅財務槓桿效應與利率風險。
- 創業融資規劃： 評估借貸經營嘅資金成本與損益平衡點。
- 加密貨幣合約交易： 計算高槓桿合約嘅爆倉價格與風險敞口。

6. 個人經驗與觀點
「槓桿係 雙刃劍—佢可以將 10% 嘅回報變成 20%，但亦可以將 10% 嘅虧損變成 20%。好多散戶只睇到『放大收益』嘅一面，但完全忽略咗 利息成本 同 強平風險。我見過太多人用 5 倍槓桿買股票，一個 10% 嘅震盪就 被強制平倉，血本無歸。呢個工具俾你嘅，就係 用 10 秒鐘睇清楚槓桿後嘅『真實回報』同『真實風險』 —等你唔再盲目借錢投資，做一個 更理性嘅槓桿投資者。」

Leverage & Margin Calculator Guide: Leveraged ROE & Financing Risk — Borrowed Investment Evaluation
1. Introduction
Are you an investor looking to use borrowed funds to amplify returns, but unsure about your actual leveraged return (ROE) and risk exposure? Or worried about margin calls and forced liquidation if the market drops? Leverage Effect and Margin are the keys to determining whether "borrowing to invest" is worth it. Our free leverage calculator lets you enter equity, borrowed amount, interest rate, and expected return to instantly calculate leveraged net ROE, break-even return, and automatically assess leverage multiplier and margin call risk. All processing happens in your browser—your data never leaves your device, ensuring 100% privacy.
2. Background & Technical Concept
Leverage Effect and Margin are a double-edged sword in financial investing—amplifying both gains and losses. Key concepts include:
- Leverage Multiplier: Total Assets ÷ Equity. A 2x leverage means every $1 of equity controls $2 of assets.
- Leveraged Return on Equity (ROE): Net return on equity after deducting interest costs. Formula: ROE = (Asset Return × Total Assets - Interest Cost) ÷ Equity.
- Break-Even Return: The minimum asset return needed to fully cover borrowing interest costs.
- Maintenance Margin: The minimum percentage of equity in total assets required by brokers—below this triggers a margin call.
- Margin Call Drop Threshold: The percentage price drop that triggers forced liquidation.
- Interest Cost: Interest payments on borrowed funds, directly impacting net leveraged returns.
3. Real-World Application Scenarios
- Stock Margin Trading: Evaluate amplified returns and margin call risk when buying stocks on margin.
- Futures Margin Trading: Calculate margin requirements and liquidation prices for futures contracts.
- Real Estate Leverage: Assess the financial leverage effect and interest rate risk of mortgage-financed property purchases.

6. Personal Insights & Expert Advice
"Leverage is a double-edged sword—it can turn a 10% return into 20%, but it can also turn a 10% loss into 20%. Most retail investors only see the 'amplified gains' side, completely ignoring interest costs and liquidation risk. I've seen too many people use 5x leverage on stocks and get forced out by a simple 10% market move—losing everything. This tool gives you exactly that ability to see the 'true return' and 'true risk' of leverage in 10 seconds—so you can stop blindly borrowing to invest and become a more rational leveraged investor."
