How Solana fees work
| Part | Amount | Refundable? |
|---|---|---|
| Base fee | 5,000 lamports (0.000005 SOL) per signature | No |
| Priority fee | Compute unit limit × price per unit (in micro-lamports); optional, set by the wallet or app | No |
| Rent deposit for a token account | (128 + 165 bytes) × rent rate; at 5,080 lamports per byte = 1,488,440 lamports (0.00148844 SOL) | Yes, when you close the empty account |
Solana's 2026 rent reduction
Solana is lowering the rent deposit in steps (SIMD-0437). Until September 2026 the rate was 6,960 lamports per byte (0.00203928 SOL per token account). It fell to 6,333 on 3 September 2026 and to 5,080 on 11 September 2026. Further steps down to 696 lamports per byte (about 0.0002 SOL per token account) were expected with a validator release around November 2026, without fixed activation dates (Chainstack docs; Solana Foundation, 2026). Change the rate field if it has moved again.
1 SOL = 1,000,000,000 lamports. Phantom usually sets the priority fee for you and shows the total before you confirm. If you see an error about rent or insufficient SOL, read fixing "not enough SOL" in Phantom.
Frequently asked questions
Why do I need SOL to receive a token?
Each token you hold on Solana lives in its own token account, which needs a small refundable rent deposit. Whoever creates the account pays it; often that is the sender, sometimes it is you.
How do I get my rent back?
Close empty token accounts. Some wallets and tools offer this; you get the deposit for each closed account back.
Why are my fees higher than 0.000005 SOL?
When the network is busy, apps add priority fees so the transaction is processed sooner. Phantom shows the fee before you confirm.
How much SOL should I keep in Phantom?
Enough for several transactions and a few new token accounts. Keeping around 0.01–0.02 SOL is a common rule of thumb, but check the fee Phantom shows.
