Solana Gas Fee Calculator: Estimate Your SOL Transaction Cost
Calculating your Solana transaction cost is straightforward once you understand the two-part fee structure. The total fee equals the base fee plus any optional priority fee: Total Fee = (5,000 × num_signatures) + ceil(CU_price × CU_limit ÷ 1,000,000) lamports.
For a simple SOL transfer with one signature and no priority fee, the total cost is just 5,000 lamports. At a SOL price of $150, this equals approximately $0.00075 — a fraction of a penny. Even complex DeFi transactions with multiple signers and priority fees rarely exceed $0.05.
Even at peak demand, the total cost of 1,000 Solana transactions is less than the gas fee for a single Ethereum swap.
Real-World Solana Fee Examples by Transaction Type
A standard SOL transfer costs 5,000 lamports (~$0.00075 at $150/SOL). A token swap on Jupiter or Raydium typically costs 10,000 to 50,000 lamports including priority fees, translating to roughly $0.0015 to $0.0075. NFT minting ranges from 20,000 to 100,000+ lamports depending on program complexity.
Compare this with Ethereum: a simple ERC-20 transfer costs $1–$5 during normal conditions, while complex DeFi interactions can exceed $50–$100 during peak demand. Solana users performing 1,000 transactions would pay less than $1 total, while the same operations on Ethereum L1 could cost hundreds of dollars.
To optimize your Solana transaction costs, set a realistic compute unit limit rather than using the default maximum of 1.4 million CUs. Programs that request fewer compute units pay lower priority fees. Use the simulateTransaction RPC call to estimate actual CU usage before submitting.
