# What's a bearish Shark Vault?

On the other hand, a user would opt for the bearish Shark Vault if they anticipate a decrease in the price of BTC/ETH. The final APY payout hinges on the price of BTC/ETH at the end of 7 days.The earnings are calculated using the following formula: Subscribed amount (1 + APY \[7/365]). Estimated earnings can also be calculated on the Shark Vault subscription page, during the subscription period. The 3 scenarios are:

1. Below the range - basic APY%
2. Inside the range - between low APY and high APY depending on the price
3. Above the range - basic APY%<br>

Here's a hypothetical situation where:

* Subscription amount: <mark style="background-color:red;">1,000 USDT</mark>
* APY: <mark style="background-color:red;">2% - 19%</mark>
* Term: 7 Days
* BTC price range: $18,000 - $21,000

Note: This example is presented for illustration purposes only and does not represent the future APY.

### Examples of scenario

**Scenario 1: Below the range Expiration price = $17,000 < $18,000, APY = 2%**

*Subscribed amount x APY x 7/365 = Earnings*

Example: 1,000 x 2% x 7/365 = 0.384 USDT (Earnings)

**Scenario 2: Within the range Expiration price = $19,500, within $18,000 - $21,000, APY = 19% - (19,500 - 18,000) / (21,000 - 18,000) x (19% - 4%) = 11.5%**

*Subscribed amount x APY x 7/365 = Earnings*

Example: 1,000 x 11.5% x 7/365 = 2.205 USDT (Earnings)

**Scenario 3: Above the range Expiration price = $24,000 > $21,000 APY = 2%**

*Subscribed amount x APY x 7/365 = Earnings*

Example: 1,000 x 2% x 7/365 = 0.384 USDT (Earnings)
