Crypto Loan Liquidation Calculator: Protect Your Investment

In the world of decentralized finance (DeFi), collateralized cryptocurrency loans offer unique opportunities but involve significant risks, foremost among them liquidation. This calculator helps you determine the liquidation price of your crypto loan, allowing you to manage risk consciously.

How DeFi Lending Works

Decentralized lending allows you to obtain loans by depositing cryptocurrencies as collateral. Unlike traditional bank loans, no documents, pay stubs, or credit checks are required: the crypto collateral is the only guarantee needed. The most well-known protocols include Aave, Compound, MakerDAO, and Venus.

The mechanism is simple: you deposit a cryptocurrency (for example Bitcoin or Ethereum) and borrow another asset, typically a stablecoin like USDT or DAI. The loan amount you can obtain depends on the Loan-to-Value (LTV) ratio.

What Is Loan-to-Value (LTV)

Loan-to-Value represents the percentage ratio between the borrowed amount and the value of the deposited collateral. For example:

  • Deposited collateral: $10,000 in ETH
  • Maximum allowed LTV: 75%
  • Maximum obtainable loan: $7,500

Each protocol sets different LTVs depending on the cryptocurrency. More volatile assets have lower LTVs to protect the system.

What Is the Liquidation Price

Liquidation occurs when the value of your collateral drops to the point where the LTV ratio exceeds the liquidation threshold. At that point, the protocol automatically sells part or all of your collateral to repay the debt, often applying an additional penalty (liquidation penalty) that can range from 5% to 15%.

Practical Calculation Example

Imagine depositing 2 ETH at a price of $2,500 each (total collateral: $5,000). You borrow 2,500 USDT (current LTV: 50%). If the protocol's liquidation threshold is 80%, the ETH liquidation price will be:

Liquidation price = Debt / (Collateral quantity x Liquidation threshold)
= 2,500 / (2 x 0.80) = $1,562.50

If the ETH price drops below $1,562.50, the position will be liquidated.

The Concept of Margin

Margin represents the distance between the current collateral price and the liquidation price. In the previous example, with ETH at $2,500 and liquidation at $1,562.50, the margin is 37.5%. A wider margin offers greater protection against market fluctuations.

How to Avoid Liquidation

There are several strategies to protect your position:

  • Maintain a low LTV — borrow only a fraction of what is allowed
  • Monitor constantly — set price alerts on platforms
  • Add collateral — if the price drops, deposit additional collateral
  • Repay part of the debt — reduce the loan to lower the LTV
  • Use stablecoins as collateral — reduces volatility risk

Important Warnings

The cryptocurrency market is extremely volatile: crashes of 30-50% within a few days are not uncommon. Before using DeFi lending, make sure you fully understand the risks.
