The complete resource for Solana priority fees — track live fee data, calculate transaction costs, and learn how to set compute unit prices to land every transaction faster on the Solana network.
Priority fees on Solana are optional fees priced in micro-lamports per Compute Unit. They are added on top of the base transaction fee to increase the likelihood that the current leader processes your transaction ahead of others. Transactions with higher priority fees are placed first in the validator's execution queue.
Priority fee formula: ceil(CU_price × CU_limit / 1,000,000) lamports. The base fee is 5,000 lamports per signature — 50% burned, 50% to the validator. The priority fee goes 100% to the validator, directly incentivizing them to process your transaction first.
This is the best resource on Solana priority fees. The fee tracker and calculator tools are exactly what I needed to stop wasting SOL on failed transactions.
After integrating the Priority Fee API into our dApp, user transaction success rates jumped to over 96%. The real-time percentile data is invaluable for our fee strategy.
