# Calculate Claimable Fees

> Calculate claimable fees for a liquidity position based on fee growth

The `MarketThree.calculateClaimableFees()` static method calculates the claimable fees for a liquidity position based on fee growth indices and position parameters.

## Usage

```typescript theme={null}
import { MarketThree } from "@exponent-labs/exponent-sdk";

// Calculate claimable fees for a position
const feeData = MarketThree.calculateClaimableFees({
  lpBalance: position.lpBalance,
  feeInsideLastSy: position.feeGrowthInsideLastSy,
  feeInsideLastPt: position.feeGrowthInsideLastPt,
  currentInsideSy: currentFeeGrowthSy,
  currentInsidePt: currentFeeGrowthPt,
  tokensOwedSy: position.tokensOwedSy,
  tokensOwedPt: position.tokensOwedPt,
});

console.log("Claimable SY fees:", feeData.claimableSy);
console.log("Claimable PT fees:", feeData.claimablePt);
console.log("Total SY fees:", feeData.totalSy);
console.log("Total PT fees:", feeData.totalPt);
```

## Parameters

| Parameter         | Type     | Required | Description                                           |
| ----------------- | -------- | -------- | ----------------------------------------------------- |
| `lpBalance`       | `bigint` | Yes      | The liquidity balance of the position                 |
| `feeInsideLastSy` | `bigint` | Yes      | Last recorded SY fee growth inside the position range |
| `feeInsideLastPt` | `bigint` | Yes      | Last recorded PT fee growth inside the position range |
| `currentInsideSy` | `bigint` | Yes      | Current SY fee growth inside the position range       |
| `currentInsidePt` | `bigint` | Yes      | Current PT fee growth inside the position range       |
| `tokensOwedSy`    | `bigint` | Yes      | Previously owed SY fees not yet claimed               |
| `tokensOwedPt`    | `bigint` | Yes      | Previously owed PT fees not yet claimed               |

## Returns

Returns an object with:

```typescript theme={null}
{
  claimableSy: bigint;
  claimablePt: bigint;
  tokensOwedSy: bigint;
  tokensOwedPt: bigint;
  totalSy: bigint;
  totalPt: bigint;
}
```

| Property       | Type     | Description                                           |
| -------------- | -------- | ----------------------------------------------------- |
| `claimableSy`  | `bigint` | Newly accrued SY fees that can be claimed             |
| `claimablePt`  | `bigint` | Newly accrued PT fees that can be claimed             |
| `tokensOwedSy` | `bigint` | Updated total SY fees owed (includes previously owed) |
| `tokensOwedPt` | `bigint` | Updated total PT fees owed (includes previously owed) |
| `totalSy`      | `bigint` | Total SY fees (claimable + previously owed)           |
| `totalPt`      | `bigint` | Total PT fees (claimable + previously owed)           |

## Calculation Details

The method uses Q64.64 fixed-point math to calculate fees:

```
fees = floor((lpBalance * feeGrowthDelta) >> 64)
```

Where `feeGrowthDelta` is the difference between current and last recorded fee growth inside the position range.
