How much SOL it takes to buy a given share of a new Pump.fun coin in block 0
A bundle's size is the share of the token supply your own wallets buy in the block the coin is created. Every new Pump.fun coin starts on the same bonding curve, so the SOL needed for a given share is the same for every launch — this calculator uses that curve directly.
As a reference, before fees: about 1.47 SOL buys 5% of supply, 3.08 SOL buys 10%, 4.88 SOL buys 15% and 6.87 SOL buys 20%. Each extra percent costs more than the last, because every buy raises the price for the next one.
Block-0 wallets are public. Buyers use bundle checkers to see how much of a coin was bought at creation, and a very large share is read as a coin that can be dumped on them — which keeps them away.
Many launches aim for a share that covers the creator's cost and leaves most of the curve for the public. Decide on the share first, then on the number of wallets.
The calculator splits the buys evenly between the dev wallet and the bundle wallets. More wallets do not change the SOL needed for a given share; they change how the holding looks on-chain and add a small fee and buffer per wallet.
Each wallet also needs a buffer for its token account and fees — 0.02 SOL per wallet is included in the total. The wallet funding calculator shows the exact amount to send to each one.
About 3.08 SOL goes into the curve for 10% of supply on a fresh coin, plus the launchpad trading fee, tip and wallet buffers. Enter 10 above to see the full total.
The number of wallets does not change how much SOL a share of supply costs. Use enough wallets that no single one holds an outsized share, without adding more than you can fund and manage.
Graduation happens when the curve's tokens are sold out, so your buys count toward it — but a coin graduates because the public keeps buying, not because of the launch block alone.
Yes. Block-0 buys are visible on-chain and in tools like our bundle checker. Keeping the share reasonable is part of a launch people are willing to buy into.
