Bitcoin transaction fee is calculated with this formula

Transaction fee (sat) = Transaction size (vbyte) * fee rate (sat/vbyte)

Transaction size will depend on some factors
- Inputs and Outputs. The more inputs and the more outputs, the bigger size.
- Transaction type. You can use Segwit address for less transaction size.
Why people should be using SegWit addresses[url=http://Fee rate will depends on network, miner capacity to confirm transaction and demand of Bitcoin users that cause Bitcoin mempools are clear or congested.
You can not control it and you only can choose a fee rate that is good for you.

Bitcoin transaction fee does not depend on how big or small the value of your transaction. I mean you will have a same transaction fee for two transactions with same transaction type, same inputs, output numbers and same fee rate. Even transaction 1 has its value is $50 and transaction 2 has its value is $1M, transaction fee can be the same like $25. I think till this example, you get the answer.
