Calculator input
A planning assumption you control. The default is a common token-account rent value, not a promise for every account type.
SOLANA RENT CALCULATOR
Estimate how much SOL your empty accounts may hold.
Enter an account count and per-account rent value to model gross recovery, the standard 5% success fee, and the 4.5% referred rate. The public scan is the source of current account-level values.

NET WITH REFERRAL
This is an estimate, not a quote. Account size and current on-chain state determine actual lamports. Network fees are separate. The free scanner reads each account before any transaction is prepared.

Current public-chain account data including each account’s lamports, balance class, ownership, and program.

The final amount depends on state revalidation, transaction construction, network fees, and wallet approval.
FORMULA
What the calculator computes
Gross estimate = eligible account count × assumed rent held per account.
Standard net estimate = gross estimate × 95%. Referred users pay 4.5% for the 30-day eligibility period, so the modeled referred net is gross × 95.5%. Network fees remain separate.
