# Calculate APRs from Aura pool yield

* BAL APR

  ```tsx
  const rewardPerYear = exactToSimple(rewardRate) * (86_400 * 365);
  const rewardPerYearUsd = rewardPerYear * rewardTokenPrice;
  const value = (rewardPerYearUsd / poolTVL) * 100;
  ```
* AURA APR

💡 Use the `getAuraMintAmount()` mentioned in the first section

```tsx
const auraPerYear = getAuraMintAmount(balApr.rewardPerYear, auraStaticQuery.data.global);
const auraPerYearUsd = exactToSimple(auraPerYear) * auraPrice;
const value = (auraPerYearUsd / tvl) * 100;
```
