Transaction calculator

The sizes of Bitcoin transactions and the associated fees can vary a lot, firstly due to the script or address standard used and secondly due to the specific number of inputs and outputs. With our transaction calculator, you can calculate the size of your transaction individually and see directly what it would currently cost you!
