Fees' calculation on the TON Blockchain

Fees

storage_fees

storage_fees = ceil((account.bits * bit_price + account.cells * cell_price) * period / 2 ^ 16)

in_fwd_fees, out_fwd_fees

msg_fwd_fees = (lump_price + ceil((bit_price * msg.bits + cell_price * msg.cells)/2^16))

ihr_fwd_fees = ceil((msg_fwd_fees * ihr_price_factor)/2^16)

// bits in the root cell of a message are not included in msg.bits (lump_price pays for them)

action_fees

action_fees = sum(out_ext_msg_fwd_fee) + sum(int_msg_mine_fee)

Config file

All fees are nominated in a certain gas amount and may be changed: The config file represents the current fee's cost.
