Hi @vdeurzen, maybe this notebook example might help: https://github.com/teachbitcoin/code-demos/blob/master/03_transactions_introduction/00_transaction_build_bx_example.ipynb

(github preview only available in desktop view)

Scroll down to “Compute output amount(s)”

I believe the default fee rate is set at 100 sat / sigop + 1 sat / byte

There is both a byte (1mb) and sigops (20k) limit to blocks, so the fee should factor in both.

This helps, thx, I can use the formula you're suggesting here 🙂
