Use this reference guide to estimate your Solana priority fee before submitting a transaction. The formula is straightforward: Priority Fee (lamports) = ceil(compute_unit_price × compute_unit_limit / 1,000,000).

‍

Knowing the exact fee before submission helps you balance speed and cost for every Solana transaction.

Fee Tiers Reference Table

Below are common compute unit price tiers and their estimated total priority fees, assuming a transaction using 200,000 compute units:

‍

Minimum (1,000 microlamports): Total priority fee ≈ 0.0000002 SOL. Best for non-urgent transactions when the network is quiet.

‍

Low (10,000 microlamports): Total priority fee ≈ 0.000002 SOL. Suitable for standard operations during normal network conditions.

‍

Medium (50,000 microlamports): Total priority fee ≈ 0.00001 SOL. Recommended starting point for most developers; reliable confirmation under moderate load.

‍

High (200,000 microlamports): Total priority fee ≈ 0.00004 SOL. For time-sensitive operations and competitive scenarios like NFT mints.

‍

Very High (1,000,000 microlamports): Total priority fee ≈ 0.0002 SOL. Premium tier for critical operations or MEV strategies requiring near-instant confirmation.

Optimizing Your Fee

The key to efficient fee usage is setting a tight compute unit limit. If your transaction only uses 50,000 CUs but you set a limit of 200,000, you pay four times more than necessary. Profile your transactions with the simulateTransaction RPC call to find accurate CU consumption before going live.
