How much does it cost to send Kaspa?

Sending Kaspa is very cheap — a typical transaction costs around 0.000023 KAS. Fees are calculated at a minimum of 1 sompi (the smallest unit of KAS) per gram of transaction data, which works out to roughly 0.000023 KAS for most everyday transfers. Some wallets simplify this by charging a flat 0.0001 KAS per UTXO (unspent transaction output) instead of calculating by gram weight. For a beginner, the practical takeaway is that Kaspa fees are negligible under normal conditions, so small amounts are not meaningfully eroded by the cost of moving them.
