Understanding what you'll pay before sending a transaction helps you plan and budget effectively on Solana. While fees are always very low, knowing the breakdown helps power users optimize their on-chain activity.

Compute Units: The Foundation of Solana Fees

Solana measures transaction complexity in Compute Units (CUs). Every operation in a transaction consumes a certain number of CUs. Simple SOL transfers use a few hundred CUs. Complex DeFi swaps or multi-instruction transactions can use tens of thousands of CUs. The default compute budget per transaction is 200,000 CUs, and the maximum is 1,400,000 CUs.

How to Estimate Your Solana Fee

Step 1 — Determine your transaction's compute unit usage. For standard transfers: ~300 CUs. Token swaps: ~40,000–80,000 CUs. NFT mints: ~20,000–60,000 CUs. Step 2 — Check the current network priority fee level. During normal conditions, 1 micro-lamport per CU is sufficient. Step 3 — Add the base fee of 5,000 lamports per signature.

Average Solana Network Fees in 2025

According to Token Terminal data, the average Solana transaction fee in 2025 is approximately $0.00204. The total daily fees paid on the Solana network reached $521,693 at peak activity. Even at these volumes, per-transaction costs remain negligible for end users.

Comparing Solana Fees vs Ethereum

A simple token transfer on Ethereum L1 costs $1.51 on average (as of mid-2025), compared to $0.0028 on Solana. That's a difference of more than 500x. Even Ethereum Layer-2 solutions charge $0.01–$0.50 per transaction, while Solana's native L1 fees stay under $0.005 for most operations.
