On PumpSwap, the fee to trade a graduated Pump.fun coin is not one flat number. It is a stepped schedule of fee tiers tied to the coin's market cap, and it starts at 1.25% for a coin that has just graduated (source: Pump.fun help center, transaction fees), then falls band by band to 0.30% for the very largest coins.
That schedule only applies after a coin graduates from the bonding curve to PumpSwap. Before that, the fee is a flat 1.25%, the same for every coin, which is covered in the broader picture of how Pump.fun fees work. Once a coin moves to PumpSwap, the fee it carries depends on how big it is.
The practical result is the part most guides skip: the same coin costs you a different amount to trade depending on when you trade it.
Where the tiered fee applies
The tiered schedule applies to coins that have graduated to PumpSwap. A freshly launched coin on the bonding curve pays a flat 1.25%; only after it graduates does the fee start moving with its market cap.
When a coin graduates, it gets its own pool on PumpSwap, which the platform calls the "canonical pool." Pump.fun's own help center draws the line clearly: a flat 1.25% before a coin graduates, then a fee that scales by SOL market cap once it moves to PumpSwap (source: Pump.fun help center, transaction fees). The graduation step itself, the moment a coin leaves the curve, is a separate topic covered in how graduation works.
So the short version: before graduation, one flat fee; after graduation, a fee that depends on size.
How the schedule steps down
The schedule runs from 1.25% down to 0.30%, in bands keyed to the coin's market cap. The bigger the coin, the lower the fee, and the total moves in one direction only: down.
Market cap here means the coin's current price times one billion tokens, the fixed figure Pump.fun uses for every coin, explained in what a coin's market cap means. Pump.fun states that its PumpSwap "fees for canonical pools vary depending on the SOL or USDC priced market cap of a coin" (source: Pump.fun docs, fees). The SOL-priced bands run roughly like this:
- A coin that has just graduated, up to about 420 SOL of market cap, pays the full 1.25%.
- A mid-sized coin, in the range of roughly 9,800 to 14,700 SOL, pays about 0.95% (source: Pump.fun docs).
- A large coin, from about 49,000 SOL, pays around 0.55%.
- The very largest coins, from 98,240 SOL and up, pay the floor of 0.30%.
There are more than twenty bands in total between those endpoints, each one a small step down, so the fee eases lower as a coin grows rather than dropping all at once. The two numbers worth remembering are the ends of the range: 1.25% at the top, 0.30% at the bottom.
Why the fee falls as the coin grows
The reason the total falls is almost entirely about the creator's cut. That creator share starts at its peak of 0.95% for a smaller graduated coin and shrinks step by step toward 0.05% for the largest ones. CoinMarketCap describes the model the same way: it "awards token creators between 0.05% and 0.95% per trade, with percentages tied to market capitalization levels" (source: CoinMarketCap, Pump.fun's new fee structure). Above the first band, the protocol keeps a flat 0.05% and the pool keeps a flat 0.20%, so the only piece that changes as a coin grows is the share paid to the creator.
Decrypt frames the same dynamic model, part of what Pump.fun brands Project Ascend, noting the creator's share is largest for coins worth roughly $88,000 to $300,000 and scales down toward 0.05% as a coin nears a $20 million market cap (source: Decrypt, Pump.fun's new fee model).
One wrinkle worth knowing: the very first band right after graduation is an exception, where the protocol still takes the larger slice and the creator gets only 0.30%, mirroring the bonding curve. Above that band the creator's share jumps to its 0.95% peak and shrinks from there. How much creators actually earn from that share is its own subject, covered in how creator fees work. For a trader, the takeaway is simpler: the fee you pay falls as the coin gets bigger.
What it costs you to trade the same coin
Because the schedule is keyed to size, the same trade on the same coin can cost very different amounts at different points in its life. This is the part that matters for your own cost.
For example, take a $1,000 trade. On a coin that has just graduated, at the 1.25% top band, the fee is $12.50. On a very large coin at the 0.30% floor, the same $1,000 trade costs $3.00. Same coin, same trade size, a fee that is roughly four times higher early on than it is once the coin is large. That is the direct consequence of the schedule: trading a small, freshly graduated coin is more expensive per dollar than trading a big, established one.
The fee is only part of what a trade costs you, though. On a thin pool, the price moves against you as you buy or sell, and that price impact and slippage can dwarf the fee. How much you can actually move without pushing the price depends on the coin's real pool depth, which is a separate question from the fee tier.
If you would prefer to trade the PUMP token itself instead of a freshly graduated coin, BloFin lists it as PUMP/USDT for spot trading, and its fee schedule shows what each order there costs before you open a position.
How to read it before you trade
Before you trade, the coin's market cap tells you which band you are in, and therefore roughly what the fee will be. A small, recently graduated coin sits near the 1.25% top; a large one sits near the 0.30% floor.
The one habit worth keeping is to check the live figure rather than trusting a number you saw quoted somewhere, because the schedule is a range and your coin's spot in it moves as its market cap moves. Note too that this is the SOL-priced schedule; coins launched with USDC as the paired token follow a separate schedule with its own market-cap bands, covered in USDC-denominated launches. Read the tier as a guide to your cost, not a fixed toll, and pair it with a look at the pool's depth before you size a trade.

Frequently asked questions
Is the PumpSwap fee a flat rate?
No. On the bonding curve, before a coin graduates, the fee is a flat 1.25%. Once a coin graduates to PumpSwap it trades in its own canonical pool, and the fee there is a stepped schedule keyed to the coin's market cap, running from 1.25% at the top down to 0.30% for the largest coins.
Why did the fee on my coin change?
Most likely its market cap crossed into a different band. The PumpSwap schedule is keyed to size, so as a coin grows the total fee steps down toward the 0.30% floor, and as it shrinks the fee steps back up. The fee is not fixed to the coin; it moves with the coin's market cap.
Which fee band is my coin in?
That depends on its current market cap, measured as price times one billion tokens. A coin that has just graduated sits near the 1.25% top band, a mid-sized coin somewhere in the middle, and a coin above roughly 98,000 SOL of market cap at the 0.30% floor. Check the live market cap to place it, since the figure moves with price.
Does a bigger coin really cost less to trade?
Yes, on the fee alone. The schedule falls as market cap rises, so a large coin carries a lower percentage fee than a small one. A $1,000 trade costs $12.50 at the 1.25% top band and $3.00 at the 0.30% floor. Price impact on a thin pool is a separate cost and can outweigh the fee saving.
Is the fee the same for USDC-denominated coins?
Coins launched with USDC as the paired token follow their own fee schedule, with market-cap bands priced in USDC rather than SOL. The structure is similar, a stepped fee that falls as the coin grows, but the specific thresholds differ, so USDC-denominated coins sit on a separate schedule.
