🛡️ 4 Key Metrics: DeFi Borrowing True Cost & Liquidation Buffer Simulator 🏦

The **DeFi Borrowing True Cost & Liquidation Buffer Simulator** is vital for yield farmers and arbitrageurs. Instantly find your **Total Annualized Borrowing Cost ($)** and the critical **Liquidation Price Buffer (%)** to manage **collateral** health. No signup • 100% client-side • Real-time KPIs.

🛠️ Loan Position Inputs

The current dollar value of the asset you supplied (e.g., ETH, BTC).

$100,000

The current dollar amount of the loan (e.g., stablecoins).

$50,000

The maximum loan-to-value percentage allowed by the protocol (e.g., 75%).

75%

The penalty charged on the borrowed amount if liquidated (e.g., 5% to 15%).

8%

The current annual percentage yield charged on the loan.

🚨 Liquidity & Cost KPIs

Total Annualized Borrowing Cost ($)

--
Interest + Annualized Liquidation Risk Cost.

Minimum Collateral Health Factor (HF)

--
Your collateral safety ratio (Liquidation at 1.0).

Liquidation Price Buffer (%)

Max % asset drop before liquidation is triggered.

Liquidation Fee Cost (Penalty) ($)

--
The realized loss on liquidation (in $).

Collateral Management: Why Your DeFi Borrowing Cost is Higher Than the APY

Decentralized Finance (**DeFi**) lending and borrowing protocols are powerful tools for maximizing **capital** efficiency, but they carry inherent risks that standard **APY** figures don't reveal. For farmers and leverage traders, the true **cost of borrowing** is not just the interest rate; it’s the existential risk of **liquidation** and the resulting penalty fee. Neglecting this risk can turn a profitable **yield farming** strategy into a catastrophic loss.

The **DeFi Borrowing True Cost & Liquidation Buffer Simulator** provides a **risk-adjusted ROI** view of your position. It instantly calculates the **Minimum Collateral Health Factor (HF)** and, most critically, the **Liquidation Price Buffer (%)**. This buffer is the percentage drop your **collateral** can sustain before the loan is automatically unwound, triggering the expensive **Liquidation Fee Cost ($)**. Mastering this math is crucial for safe, long-term **smart living** in Web3.

"The **Health Factor** is your lifeline in **DeFi**. Always maintain a generous **Liquidation Price Buffer (%)**, especially with highly **volatile** assets, as even a minor market crash can wipe out your **APR** gains instantly." — **Stani Kulechov, Founder of Aave (Emphasizing Safety Margins)**

Understanding the Liquidation Trigger and True Cost

A collateralized loan in **DeFi** is protected by a **Liquidation Threshold** defined by the protocol and the asset's volatility (Max **LTV**). When the value of your supplied **collateral** drops below the value of your loan plus the liquidation threshold, your position is open to liquidation (HF drops to 1.0). The liquidator pays off the loan and claims a portion of your collateral, including the substantial **Liquidation Fee** (often 8% to 15% of the borrowed amount).

Our simulator factors in both the **Annual Borrowing APY** and an annualized risk cost associated with the potential **Liquidation Fee Cost ($)**. This gives you the **Total Annualized Borrowing Cost ($)**, which is the most transparent and realistic expense of holding the loan.

Liquidation Threshold ($\mathbf{LT}$):

$$ \mathbf{LT} = \frac{1}{\mathbf{Max \text{ LTV \text{ \%}}}} $$

Liquidation Price Buffer ($\mathbf{B_{L}}$):

$$ \mathbf{B_{L}} = \left(1 - \frac{\mathbf{Borrowed \text{ Value}} \times \mathbf{LT}}{\mathbf{Collateral \text{ Value}}}\right) \times 100 $$
"For advanced **treasury** management, the cost of capital must include the risk-adjusted cost of catastrophic failure. The **liquidation fee** is the 'insurance premium' you pay if your **hedging** strategy fails." — **MakerDAO Governance (On Risk-Adjusted Cost of Capital)**

Use Cases: Safe Leverage and Risk Parity

This tool empowers investors to manage **leverage** safely and effectively:

Scenario 1: Arbitrage Strategy: A user borrows \$100,000 against \$150,000 of collateral (66% LTV). The tool shows a **Liquidation Price Buffer (%)** of 22.5%. This provides confidence that a typical market swing will not trigger liquidation. The calculated **Total Annualized Borrowing Cost ($)** helps determine if the expected yield (**APR**) from the borrowed funds is truly profitable after accounting for all risks.

Scenario 2: Setting a Collateral Target: A farmer knows they need to borrow \$50,000 and wants a minimum of 30% **Liquidation Price Buffer (%)**. By adjusting the **Collateral Value** input, they can determine the minimum amount of **capital** they must supply to achieve their desired safety margin, mitigating the risk of the **Liquidation Fee Cost**.

Scenario 3: Comparing Protocols: Two protocols offer the same 5% **APY**, but Protocol A has an 80% Max **LTV** and a 10% **Liquidation Fee**, while Protocol B has a 70% Max **LTV** and a 5% Fee. By running two simulations, the user can see which protocol offers a safer **Health Factor** and a lower **Total Annualized Borrowing Cost ($)** based on their chosen leverage level.

"Optimal **collateral** utilization is about finding the sweet spot between high **APR** leverage and sustainable **risk parity**. Borrowing near the max LTV is not efficient; it’s an invitation to liquidation bots." — **Chainlink Labs (On Smart Contract Risk)**
"Never underestimate the cost of liquidation. That 8% to 15% fee is pure profit loss that negates months of accumulated **compounding** interest. The buffer is your primary defense against this **amortization** event." — **Aave Community Analyst (Focusing on Loss Prevention)**
"Transparency in **DeFi** means understanding all costs. This calculator forces you to price in the penalty, giving you a clearer picture of your **risk-adjusted ROI** before you commit your valuable **capital**." — **Gavin Wood, Founder of Polkadot (Advocating for Transparency)**
