# How to get TON-stTON rate

The fundamental TON-stTON rate is calculated using the formula:

**`stTON rate = ton_total_supply / jetton_total_supply`**

To retrieve `ton_total_supply`  and `jetton_total_supply` you need to invoke '**get\_full\_data**' method in **Financial** contract:

```
// TL-B:
get_full_data#_ = (
    jetton_total_supply:Coins 
    ton_total_supply:Coins 
    commission_total_supply:Coins
    commission_factor:uint16
    commission_address:MsgAddressInt
    admin_address:MsgAddressInt
    transaction_address:MsgAddressInt
    content:^Cell
    jetton_wallet_code:^Cell
    unstake_request_code:^Cell
    last_lockup_epoch:uint32
    lockup_supply:Coins
    next_lockup_supply:Coins
    later_lockup_supply:Coins
    next_unstake_request_index:uint64
)
```

These two values `0x2524443fb29fa1` and `0x275f0f797cee6d` are hexadecimal representations of `jetton_total_supply` and `ton_total_supply` . To convert them to decimal and compute the stTON price, you can use the following code in Python:

```
jetton_total_supply = int("0x2524443fb29fa1", 16)
ton_total_supply = int("0x275f0f797cee6d", 16)
```

**Here is an example in Python:**

```
from pytoniq import LiteClient

async with LiteClient.from_mainnet_config(trust_level=2) as client:
   result = await client.run_get_method(
       address="EQDNhy-nxYFgUqzfUzImBEP67JqsyMIcyk2S5_RwNNEYku0k",
       method="get_full_data",
       stack=[],
   )
stton_price_in_ton = result[1]/result[0]
```
