RiskMemecoins are highly speculative, and most lose nearly all their value. Nothing here is financial advice.
Bonding curve calculator
Type how much SOL a buy spends to see the tokens it gets, its share of the supply, and the coin's market cap and bonding curve progress afterwards. Leave “already in the curve” at 0 for the first buy on a new coin.
Every pump.fun coin starts on the same curve, so the answer depends only on how much SOL is already in it. A curve that holds about 85 SOL has sold out, and the coin graduates.
Launch and bundle cost calculator
Add up everything a pump.fun launch through memetools needs: every wallet's buy, pump.fun's 1.25%, our fee, Solana's deposits and the bundle's tip. Set the bundle wallets to 0 for a launch from one wallet.
The launch wallet buys first and each bundle wallet after it, so each pays a little more per token than the one before. pump.fun bundle launches explains the modes, and Solana bundlers compared shows what other tools charge for the same launch.
Creator fee calculator
On the bonding curve a coin's creator earns 0.30% of every trade, buys and sells together. Type a trading volume to see what that comes to.
After a coin graduates the creator's rate changes with its market cap, and a Holder Rewards coin pays this to holders instead. Both are in pump.fun creator fees.
How the bonding curve maths works
A pump.fun curve starts with 30 SOL and 1.073 billion tokens of virtual reserves. A buy takes pump.fun's 1.25% off first, and the rest gets: tokens = SOL × token reserves ÷ (SOL reserves + SOL). Each buy leaves fewer tokens and more SOL in the reserves, so the next one pays more.
The first buy on a new coin
| Buy spends | Tokens | Share of supply | Market cap after | Curve after |
|---|---|---|---|---|
| 0.1 SOL | 3,520,919 | 0.35% | 28.14 SOL | 0.44% |
| 0.5 SOL | 17,376,518 | 1.74% | 28.89 SOL | 2.19% |
| 1 SOL | 34,199,203 | 3.42% | 29.83 SOL | 4.31% |
| 2 SOL | 66,285,714 | 6.63% | 31.76 SOL | 8.36% |
| 5 SOL | 151,660,777 | 15.17% | 37.92 SOL | 19.12% |
| 10 SOL | 265,758,514 | 26.58% | 49.4 SOL | 33.51% |
| 20 SOL | 426,004,963 | 42.6% | 76.9 SOL | 53.71% |
| 40 SOL | 609,875,666 | 60.99% | 150.08 SOL | 76.9% |
Market cap is the price of one token times the whole supply of 1 billion. It's in SOL here; multiply by SOL's price for dollars.
What a calculator can't tell you
These are estimates for the curve as you describe it. Other people's trades move the price before yours lands, fees change, and no number here says what a coin will be worth.
- A real buy sets a limit above its price, so it can cost a little more than shown if someone buys first.
- pump.fun's fees are from its fee page, checked on 11 November 2026. It changes them several times a year. pump.fun fees has the full list.
- Solana's deposits are rounded: about 0.0225 SOL for a coin's accounts and about 0.005 SOL for each bundle wallet.
- Trades in pump.fun's own apps pay a 0.45% Platform Fee that isn't counted here.
- Most coins on pump.fun never graduate. Nothing here is financial advice.
