How much are Monero transaction fees?

The table above shows live data on the transaction fees paid via Monero vs Bitcoin. Note that transaction fees will increase if you increase the "priority" of the transaction. A higher priority will increase the fee so that it successfully competes with other transactions to become part of the next block on the blockchain.

The transaction fee also increases if you are sending funds that you were originally sent via lots of tiny transactions. This is because the size of the transaction data will be larger.

Monero has an adaptive block size, so most of the time you will not have to increase the priority of your transactions and pay higher fees to get your transactions processed. However, Bitcoin currently has a fixed block size and the number of transactions regularly exceeds the room available in the blocks that are mined. This means you need to take care to increase your Bitcoin transaction fees to ensure they are processed within a reasonable timeframe.

Note that to support "microtransactions", Bitcoin and Monero are likely to support systems like the "Lightning network" in order to radically reduce the cost of small payments in the future.

With the introduction Bulletproofs transaction size and fees have been significantly reduced.
