how to use the solana priority fee calculator
- Enter the priority fee the way your bot asks for it: a total in SOL, or a compute-unit price in micro-lamports with a compute-unit limit.
- Add the Jito tip (bribe) if you use one.
- Enter the trade size in SOL and your platform's fee per side.
- Say whether this is the first buy of the token (a token account is opened) and how many round trips you make per day.
formula
base fee = 5,000 lamports per signature priority fee = compute-unit price (µ-lamports) × compute-unit limit ÷ 1,000,000 round trip = 2 × (base + priority + tip) + platform fee on both sides rent for a new token account = 0.00148844 SOL, refundable
the parts of a Solana transaction fee
- Base fee: 5,000 lamports (0.000005 SOL) per signature, half of it burned.
- Priority fee: optional, paid per compute unit to get included faster when blocks are busy. Bots usually let you set it directly in SOL.
- Jito tip: an optional payment to the block builder for bundle inclusion; not a network fee.
- Rent: opening a token account locks 0.00148844 SOL (165 bytes) or 0.00151384 SOL (Token-2022), returned when you close the empty account.
small trades pay the most
A 0.001 SOL priority fee plus a 0.001 SOL tip is 0.002 SOL per transaction, or 0.004 SOL for a buy and a sell. On a 0.1 SOL trade that is 4% before the platform fee; on a 1 SOL trade it is 0.4%. On FOMO, Solana network costs are included in its fee bands instead of being charged separately.
frequently asked questions
How is the Solana priority fee calculated?
Compute-unit price in micro-lamports times the compute-unit limit, divided by 1,000,000 to get lamports. 50,000 micro-lamports × 200,000 CU = 10,000,000,000 ÷ 1,000,000 = 10,000 lamports, or 0.00001 SOL.
What priority fee should I use for memecoins?
It depends on how busy the network is. Start from your bot's default and raise it only when transactions fail to land, typically during hyped launches. A higher fee buys faster inclusion, not a better price, and on small trades it can cost more than the move you are chasing.
Is the Solana rent fee refundable?
Yes. The rent in a token account comes back when you close the empty account. See the Solana rent calculator.
