# Get Claimable Interest

> Calculate claimable interest for a yield position

The `getClaimableInterest` method on the `YtPosition` class calculates the amount of interest available for collection, denominated in the base token.

## Usage

```typescript theme={null}
import { YtPosition, Vault, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const vault = await Vault.load(LOCAL_ENV, connection, vaultAddress);
const ytPosition = await YtPosition.loadByOwner(LOCAL_ENV, connection, wallet.publicKey, vault);

const claimableInterest = ytPosition.getClaimableInterest(vault.currentSyExchangeRate);

console.log("Claimable interest (base):", claimableInterest);
```

## Parameters

| Parameter      | Type     | Description                                |
| -------------- | -------- | ------------------------------------------ |
| `currentIndex` | `number` | The current SY exchange rate for the vault |

<Tip>
  Use `vault.currentSyExchangeRate` for the `currentIndex` parameter. This ensures the calculation uses the latest exchange rate from the loaded vault state.
</Tip>

## Returns

Returns a `number` representing the claimable interest in raw base token units. The calculation accounts for:

* Accrued yield since the last update based on exchange rate changes
* Previously staged interest
* Protocol interest fees (deducted automatically)
* Rounding adjustments (conservative, in favor of the protocol)
