About the Crypto DeFi Liquidation Threshold Calculator
Knowing your exact liquidation price is the most important risk management tool in DeFi lending. When your collateral drops below this price, liquidators can seize your assets. The liquidation price depends on your borrowed amount, collateral quantity, and the protocol's liquidation threshold.
This Liquidation Threshold Calculator computes the precise token price at which your DeFi position becomes liquidatable. Enter your collateral details, debt, and protocol parameters to see your liquidation price and the percentage drop required to reach it.
By knowing this number, you can set alerts, plan stop-losses, or add collateral proactively before dangerous price levels are reached.
Use the result to map token-release or fee scenarios and revisit the model when market conditions, unlock terms, or portfolio assumptions change.
When This Page Helps
Liquidation penalties of 5-15% make prevention far cheaper than the cure. This calculator gives you the exact price to watch, the percentage buffer you have, and helps you plan collateral management.
How to Use the Inputs
- Enter the amount of tokens you've deposited as collateral.
- Input the current token price.
- Set the protocol's liquidation threshold (LTV) for that asset.
- Enter your total borrowed amount in USD.
- View your liquidation price and safety margin.
Formula used
Liquidation Price = Borrowed / (Collateral Amount × Liquidation Threshold). Price Drop % = (1 − Liquidation Price / Current Price) × 100.Example Calculation
Result: Liquidation price = $1,939.39
Liquidation Price = $8,000 / (5 × 0.825) = $8,000 / 4.125 = $1,939.39. Current price is $3,000. Drop needed: (1 − $1,939 / $3,000) × 100 = 35.4%. Your position is safe unless ETH drops over 35%.
Tips & Best Practices
- Set price alerts at 10-20% above your liquidation price.
- In volatile markets, maintain a wider buffer (40%+ from liquidation).
- Adding more collateral lowers your liquidation price.
- Repaying debt also lowers your liquidation price.
- Accruing interest slowly raises your liquidation price over time.
- During flash crashes, your position may be liquidated and recover — the damage is done.
Liquidation Anatomy
The liquidation process: (1) Price drops. (2) Oracle updates on-chain price. (3) Health factor dips below 1.0. (4) Liquidation bot detects the opportunity. (5) Bot calls liquidation function. (6) Your collateral is seized and debt partially repaid. Steps 2-6 happen in seconds.
Oracle Lag and Flash Crashes
On-chain oracles update periodically (every few minutes). During a flash crash, the oracle might lag behind the real price, either protecting you (flash crash recovers before oracle updates) or hurting you (oracle updates to a temporarily low price).
Building a Liquidation Safety Net
Use tools that automatically add collateral or repay debt when prices approach your liquidation level. DeFi Saver, Instadapp, and similar tools can create automated protection that acts within blocks of your health factor dropping.

Frequently Asked Questions
A liquidation bot repays up to 50% of your debt and seizes equivalent collateral plus a bonus (5-10%). Your remaining position survives with less collateral and less debt, but at a net loss from the penalty.
On protocols with dynamic interest, your debt can grow faster than expected, effectively raising your liquidation price. Oracle delays can also cause liquidation slightly above the theoretical price.
The close factor is the maximum percentage of debt that can be liquidated in one transaction (typically 50%). After a partial liquidation, your health factor is restored partway, and your position survives at reduced size.
Liquidators receive collateral worth more than the debt they repay. A 5% bonus means for every $100 of debt repaid, they get $105 of collateral. This bonus is a cost to you — the borrower.
You can repay your own debt before liquidation to avoid the penalty. Some tools like DeFi Saver offer automated deleveraging that repays debt using your collateral before external liquidators can act.
More volatile assets need lower thresholds (meaning less borrowing power per dollar of collateral) because their prices can drop faster. Stablecoins have higher thresholds (95%+) since their value is stable.
