What Is Solana Priority Fee
Solana priority fees are optional additional payments made in micro-lamports per compute unit. Added on top of the base transaction fee of 5,000 lamports, they allow users to boost transaction priority in the validator queue — ensuring faster execution for time-sensitive actions like DeFi swaps, NFT mints, and token trades.
How Priority Fees Work
The priority fee formula is: priorityFee = ceil(computeUnitPrice × computeUnitLimit / 1,000,000) lamports. 100% of priority fees go directly to the block-producing validator, while base fees are split 50% burned and 50% to validators. Even during high network congestion, priority fees typically stay under $0.01.

Priority Fee Formula
The total fee formula: priorityFee = ceil(computeUnitPrice × computeUnitLimit / 1,000,000) lamports. A typical transaction uses 200,000–400,000 compute units. At 40,000 microLamports/CU, that equals roughly 0.000008–0.000016 SOL in priority fees.
Fee Levels Explained
Low (25th percentile): budget-friendly for non-urgent transactions. Medium (50th percentile): recommended for most applications. High (75th percentile): for time-sensitive DeFi operations. Very High (95th percentile): MEV strategies and critical operations requiring guaranteed fast confirmation.
