Solana Fee Calculator – Estimate Your Transaction Cost

Use the FeeSol Solana fee calculator to estimate the total cost of your Solana transaction before you send it. Understanding fee breakdown helps you set the right compute unit limit and priority fee to avoid overpaying or getting stuck in the mempool.

A typical Solana transaction costs as little as 0.000005 SOL in base fees — approximately $0.0005 at $100/SOL. With priority fees factored in, the average transaction cost is around $0.0033. For most users, Solana remains dramatically cheaper than any other smart-contract-capable blockchain.

Transaction Fee Breakdown

Total Solana transaction fee = Base Fee + Priority Fee. Here is how each component is calculated.

• Base Fee = 5,000 lamports × number of signatures
• Priority Fee = CU price (micro-lamports) × CU limit / 1,000,000
• Storage Rent = ~0.00203928 SOL per new token account (refundable)
• Total fee is deducted before execution — charged even on failed transactions

How to Minimize Solana Fees

Setting an accurate compute unit limit is the single most effective way to reduce Solana fees. Many wallets over-estimate the default CU limit, causing you to pay more priority fees than necessary. Use simulation (simulateTransaction) to find the actual CU consumption of your transaction, then set your limit 10–20% above the simulated value for safety.

For storage rent, you can reclaim SOL by closing unused token accounts. Most wallets have a built-in "close empty accounts" feature that returns the ~0.002 SOL deposit to your wallet for each closed account.
