# bmGRAM pricing

bmGRAM/GRAM token price is continuously calculated by the formulas. 

Staking GRAM:

> `bmGRAM amount = GRAM staked / bmGRAM price`

Unstaking bmGRAM:

> `GRAM amount = bmGRAM unstaked * bmGRAM price`

bmGRAM is priced by **bemo** in GRAM tokens and is calculated by the formula:

> `bmGRAM price = (gram_pool + staking_reward - bemo_fee) / ton_pool`

`ton_pool` – GRAM tokens in the pool \
`staking_reward` – bemo validation rewards

\
The bmGRAM app price accounts for the reward accumulated after each validation round. 

Due to the nature of staking, the bmGRAM app price is constantly growing. The staked token price growth rate equals the TON blockchain staking yield ex **bemo** protocol fees.

**bemo** application fee equals twenty percent of the TON blockchain staking rewards. The fee includes the validation and the application services and is charged after every validation round.
