# Preview and Limit Methods

Preview methods are ideal for quoting expected returns in your UI before a user submits a transaction.

```tsx
const expectedShares = await client.previewDeposit({ vault, assets });
const requiredAssets = await client.previewMint({ vault, shares });
const expectedAssets = await client.previewRedeem({ vault, shares });
```

Limit methods help the frontend determine whether a user has sufficient balance and whether direct withdraw/redeem flows are available.

```tsx
const maxAssetsToDeposit = await client.maxDeposit({ vault, receiver });
const maxAssetsToWithdraw = await client.maxWithdraw({ vault, owner });
```
