DeFi Loan-to-Value Ratio
Calculates the size of a crypto-backed loan relative to the value of collateral posted, the inverse perspective of collateralization ratio.
Interpretation
LTV (%) = (Loan Amount / Collateral Value) × 100. The ratio of loan to collateral. Used to determine borrowing capacity.

| Collateral Value | Value of collateral posted | currency |
What it means
The Loan‑to‑Value (LTV) ratio is the inverse of collateralisation. It indicates the maximum loan relative to collateral. A lower LTV means less risk. This is used by lending protocols to set borrowing limits. Understanding LTV helps borrowers know how much they can borrow and to manage their liquidation risk.
Worked example
DeFi Loan‑to‑Value Ratio – Two Detailed Examples
Real‑World| Parameter | Value |
|---|---|
| Loan Amount | $10,000 |
| Collateral Value | $15,000 |
| Parameter | Value |
|---|---|
| Loan | $8,000 |
| Collateral | $10,000 |
Common mistakes
- Loan‑to‑value (LTV): Loan amount divided by collateral value.
- Lower LTV: Safer for the lender.
- Liquidation: If LTV exceeds a threshold, the position may be liquidated.
- Different assets: Different LTV limits for different collateral types.
Applications
DeFi loan‑to‑value ratio (LTV) is the inverse of the collateralisation ratio, representing the loan amount as a percentage of collateral value. Lenders and borrowers use this to determine borrowing capacity and to assess risk. A lower LTV means less risk for lenders. Understanding LTV is crucial for participating in DeFi lending markets.
- Determining borrowing capacity based on collateral
- Assessing the risk of a loan position
- Setting loan terms and interest rates
- Monitoring exposure to price volatility
- Educational understanding of lending metrics
Frequently Asked Questions
LTV = (Loan Amount / Collateral Value) × 100. For example, if you borrow $10,000 against $15,000 in collateral, your LTV is 66.7%. Lower LTV means more safety.
It varies, but common maximums are 50% for volatile assets (like ETH), 75% for stablecoins, and up to 90% for some stablecoin-only pools. Always check the protocol's risk parameters.
Your position becomes eligible for liquidation. To avoid this, you should maintain an LTV well below the maximum, giving yourself a safety buffer for price drops.
Usually, higher LTV results in higher interest rates because the loan is riskier for the lender. Some protocols use dynamic rates based on LTV and utilization.
Yes, by keeping LTV low you reduce liquidation risk, but you also leave more collateral unused. Some investors borrow up to 50% to leverage their positions while maintaining a safety margin.
Typically, LTV is calculated on the outstanding debt including accrued interest. As interest accrues, your LTV rises, so you must account for that.
It updates in real-time as collateral and debt values change. Monitoring tools show the current LTV dynamically.
They are inverses: LTV = 100 / CR (in percentage terms). A 150% CR equals a 66.7% LTV. Both measure the same risk.
