# Utilization

### **What Is Utilization?**

**Utilization** refers to the percentage of total available funds in a lending pool that have been borrowed by users. It reflects how much of the pool’s liquidity is currently in use.

**Formula:**

Utilization=Total Borrowed / Total Lent × 100%

For example:

* If a pool has **1,000 USDT deposited** and **800 USDT borrowed**,
* Then **Utilization = 80%**.

***

### **Why Is Utilization Important?**

* **For Lenders:**
  * High utilization means more of their funds are actively lent out, potentially earning **higher interest.**
  * Very high utilization, however, may **limit withdrawal flexibility**, as most funds are borrowed.
* **For Borrowers:**
  * High utilization can lead to **higher interest rates**, as demand for liquidity is strong.
  * Low utilization generally means **lower borrowing costs** and easier access to funds.
* **For the Exchange:**
  * Utilization helps balance supply and demand in the lending market.
  * It influences the **dynamic interest rate model** — interest rates often increase when utilization is high, encouraging repayment and new deposits.

***

### **Key Parameters**

* **Optimal Utilization:** The point where interest rates begin to increase rapidly to encourage more lending and loan repayments.
* **Throttled Utilization:** The utilization rate threshold where lend redeems and new borrows are paused to prevent 100% utilization.
* **Max Utilization:** The maximum utilization rate threshold where no lend redeems or new borrows are allowed, and positions may be automatically deleveraged.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://support.backpack.exchange/exchange/borrow-and-lend/utilization-interest-rates-risks/utilization.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
