As the transaction fee of Bitcoin depends on transaction size and network volume, it will keep on fluctuating as per the change in network volume and size of the transaction.
There is no fixed bitcoin transaction but it also depends on which wallet that you have used, in custodial wallet which are higher fees than the non custodial wallet. The fees are always mattered on the mempool status and the fee depends if the network is not experiencing heavy traffic.
Another case depended on your speed transaction, faster transactions mean higher fees could be paid. For lower fees, I suggest adopting a lightning network, this is good a multi send micro transactions.
