# Borrowing basics

> What a borrow position is, how much you can draw, and the four actions available on an open position.

A borrow position pairs collateral you post with debt you draw against it. You keep exposure to the collateral (it stays yours and continues to earn its supply rate where the market pays one) while gaining the use of the borrowed asset.

Each position is a distinct object with its own collateral, its own debt, and its own [risk parameters](/risk/risk-parameters) inherited from the market. Positions do not cross-collateralize: a healthy position will not rescue a failing one.

## What you can draw

Your borrowing capacity is the lower of two ceilings:

1. Your collateral's capacity: collateral value × the market's max borrowable LTV, less what you already owe.
2. The market's available liquidity: a market cannot lend what it does not hold.

Whichever binds, the platform quotes the lower figure, reduced by a **3% safety margin**. That margin exists because the protocol re-checks solvency at execution against the live oracle price and against interest accrued since you opened the form; a figure at the theoretical limit would frequently be rejected on arrival. To reach the true maximum, borrow in stages.

## The four actions

| Action   | Effect on collateral | Effect on debt | Effect on health factor |
| -------- | -------------------- | -------------- | ----------------------- |
| Deposit  | Increases            | No change      | Improves                |
| Borrow   | No change            | Increases      | Worsens                 |
| Repay    | No change            | Decreases      | Improves                |
| Withdraw | Decreases            | No change      | Worsens                 |

Before you confirm, the form shows the position as it stands and as it would be afterward: LTV, health factor, and liquidation price on both sides. Both sides are computed from the same model, so the comparison is like-for-like rather than two differently derived numbers.

Check the projected health factor, not just the amount. That figure is the one that tells you whether the action leaves you with usable buffer.

## Withdrawing collateral while you have debt

You can withdraw only down to the collateral your remaining debt requires, again with the 3% margin applied. With debt outstanding, expect a meaningful portion of your collateral to be locked: that is what is backing the loan.

To withdraw everything, repay the debt in full first.

## Interest

Interest accrues on your debt continuously at the market's borrow rate, which floats with utilization. Two consequences:

* Your debt grows without any action from you, so your health factor drifts down in a completely flat market.
* Your borrow cost is not fixed. A rate that was comfortable at open can rise materially, which is what makes a leveraged yield position vulnerable. See [Net APY](/earning-yield/net-apy).

There is no term and no maturity date. The position stays open until you close it or it is liquidated.

## Before you open one

Be clear on three things: what price fall the position survives (its [liquidation price](/risk/liquidation)), what the debt costs you now and could cost at higher utilization, and how you would add collateral quickly if the market moved against you. If the answer to the third is "sell the collateral", the position is more fragile than it appears.
