Every fee a pump.fun trade pays

Updated 3 October 2026 · by AtroX · Belphor Research · the data behind this guide

As of October 2026, a trade on pump.fun's bonding curve pays pump.fun 1.25%, of which 0.30% goes to the coin's creator, and a trade sent through a third-party terminal or Telegram bot usually pays that tool another 1%. Add Solana's network fees and slippage, and a 1 SOL round trip through a 1% tool costs about 4.7% before slippage, 0.04701 SOL, at the settings in the worked example below.

Line one: pump.fun's own fee

pump.fun's fee page (last updated 20 May 2026) is the first line of every trade on its venue, and it is the same whichever app sends the order.

The full tier table and the split between creator, protocol and liquidity providers are in pump.fun creator fees explained. pump.fun's page adds that its own web app, pump.fun/advanced and mobile app charge nothing beyond these, that some mobile users may pay up to 0.1% more on certain transactions, and that other interfaces may charge their own fees.

Line two: the network

Solana's documentation sets the chain's part. Every transaction pays a base fee of 5,000 lamports per signature (0.000005 SOL), half burned and half paid to the validator. A priority fee is optional: the trader sets a price per compute unit in micro-lamports, the fee is that price times the compute-unit limit divided by one million, in lamports, and all of it goes to the validator. Some tools also send a Jito tip, a separate bid to validators; Jito's documentation sets the minimum at 1,000 lamports for bundles. In SOL terms the base fee is negligible. The priority fee is whatever the trader or the tool sets, and on a small position it is the line that bites.

Line three: the interface

A trade sent through a third-party terminal or bot pays that tool's fee on top of pump.fun's. These are the rates each tool states on its own pages, read on 3 October 2026.

Each rate links to its source in the list at the end of this page. A fee is usually taken in SOL from the amount spent on a buy and from the proceeds of a sell.

This table compares the documented interface fees; venue fees, network fees and execution prices must be assessed separately.

Line four: slippage and price impact

The last line is not a fee and appears on no fee page. Price impact is how far a trade moves the price by itself: on the bonding curve the formula moves it, in a pool the depth decides it, and on a young coin both are thin. Slippage tolerance is the worst price the trader agrees to accept before the order is sent; a wide setting fills more often and fills worse. Together they often cost more than every stated fee on a small coin. Slippage and price impact explains both, and what liquidity really means explains why pool depth decides the bill.

A worked example

A buy and a sell of the same coin on the bonding curve, sent through a tool charging 1%, at an unchanged price, with a priority fee of 0.001 SOL per transaction. The priority fee is an example setting, not a recommendation, and slippage is left out because it depends on the coin.

The percentage lines scale with the position; the fixed lines do not. At 1 SOL the round trip costs 4.7% before slippage, and at 0.1 SOL it costs 6.5%, because the priority fee weighs ten times more. These totals are an equal-notional cost illustration, not an exact breakeven price move. Breakeven depends on fee deduction, token quantity received and the amount sold, as well as slippage. That is why expectancy is computed after costs, never before. What the same costs look like on a position screen one second after a buy is in why your position shows a loss right after you buy.

Where Belphor fits

For comparison, the Reflex page in the Belphor app states the fee as: "Live trades carry a 0.5% execution fee, half of the 1% most Solana trading bots charge." Live trading on the Trade desk is coming soon and needs live access, a funded trading wallet and a passkey. It is stated here so the comparison is complete; Belphor is a signal and record layer, not a terminal.
