Frequently asked questions
What is rent-exempt SOL on Solana?
Every account on Solana needs to hold a minimum SOL deposit proportional to its size, called the rent-exempt minimum. Pay it once and the network keeps your account on chain forever; close the account and the SOL comes back to you. The rate is roughly 6,960 lamports per byte plus a 128-byte overhead — a standard SPL token account costs ~0.00204 SOL.
How is rent calculated?
Solana's formula is `(bytes + 128) × 3,480 lamports/byte/year × 2 years`. The 128-byte overhead accounts for account header data, the 3,480 lamports/byte/year is the per-byte rate, and the 2-year multiplier is the exemption threshold. This calculator pulls the live rate from the network on load and computes locally as you type.
What sizes are typical for common accounts?
System account (just holds SOL): 0 bytes. Mint account: 82 bytes. SPL Token account: 165 bytes. Multisig: 355 bytes. Metaplex NFT metadata: ~679 bytes. Token-2022 accounts can be larger when using extensions like transfer fees or confidential transfers.
Will I get this SOL back?
Yes. The rent-exempt deposit is fully refundable when the account is closed. The Solana runtime returns it to a destination you specify (your wallet by default) the moment the close instruction succeeds. SOLTidy's Token Account Closer recovers exactly this rent for empty SPL and Token-2022 accounts.
