How it works
Sizes assume one input type, standard signatures and the selected output count. Consolidation spends the inputs into one output; the future spend compares those inputs with one consolidated input. Rates are scenarios, not forecasts.
Combining inputs links them publicly on the blockchain. This calculator estimates costs and does not create or sign transactions.
