# What a GMGN Trade Actually Costs: All-In Fee Calculator
> GMGN advertises a flat 1%. This calculator shows what a trade charges once the priority fee, tip and gas land, with every default read from GMGN's own docs.

GMGN's fee is one number and it is honest: a flat 1% per transaction, published in its own documentation, with no sniper surcharge, no copy-trading surcharge and no subscription. That number is also not what a trade costs you, and the difference is not small on the trade sizes most people actually place.
On a 0.1 SOL round trip at GMGN's own recommended 0.006 SOL per leg, the flat 1% comes to 0.002 SOL and the on-chain fee comes to 0.012 SOL. You are charged **about 14% of the position** against an advertised 2% for the round trip, before slippage. On a 1 SOL round trip with identical settings it is about 3.2%. Nothing about the rate changed; the fixed part just stopped dominating.
## The Headline Fee, and What It Leaves Out
GMGN's [fee documentation](https://docs.gmgn.ai/index/gmgn-fees-settings.md), read 18 August 2026, states that it "only charges a 1% handling fee for a single transaction, and there are no additional charges," with a worked example of a 1 SOL trade paying 0.01 SOL. Charged on the buy and again on the sell, so a round trip is 2% of the amount traded.
Two things sit outside that, and the same page names both.
**The on-chain fee.** GMGN gives the formula directly: on-chain fee equals priority fee plus tip fee plus gas. It also states that priority and tip fees "are additional fees paid to speed up transaction processing, used to bribe nodes to prioritize your tx, and are not collected by GMGN." The priority fee goes to validators, the tip to private nodes. Both have a documented range of 0.0001 SOL minimum to 2 SOL maximum, and both are set by you. Because GMGN never receives that money, a mis-set priority fee cannot be refunded by anyone.
**Slippage.** Not a fee at all, which is why the calculator below keeps it in its own row. It is a tolerance you authorize before the trade. GMGN recommends auto slippage for manual trades, 30 to 35% for automated buys, sells and limit orders, and 50% or more for new or hot tokens. Setting 50% does not cost 50%; it permits a fill half a level below the quote, and on a thin pool that permission gets used.
The reason this matters more here than on a normal exchange is arithmetic rather than pricing. The 1% scales with your position. The on-chain fee does not.
## What Each Input Means
**Chain.** GMGN's handling fee is the same 1% on Solana, BSC, Ethereum, Base, Tron and Blast, so the platform side does not vary by chain. The chain side does, and this is where most calculators start inventing numbers. GMGN publishes its recommended on-chain amounts in SOL only. It documents the formula for every chain and names figures for none of them outside Solana, so the five non-Solana chains open with an empty on-chain field and a note telling you to enter what your own wallet quotes. An unsourced gas figure would be worse than an empty box.
**Trade size.** In the chain's native token, because that is the unit GMGN's own documentation and worked example use. This is the input that moves the answer most, and not in the direction people expect: the percentage cost falls as size rises, because the fixed part is being divided by a bigger number.
**On-chain fee per leg.** Priority fee plus tip plus gas for one transaction. GMGN's documented Solana guidance is 0.002 to 0.005 SOL when speed does not matter, and **0.006 SOL or more for auto buy, auto sell and limit orders**, which is the default here because automated orders are where this cost compounds. Anti-MEV is worth knowing about while you are in this field: GMGN states it requires a priority fee of at least 0.002 SOL to enable at all, so protection has a floor.
**Slippage tolerance.** Your authorized worst fill, in percent. The calculator prints it as a ceiling rather than folding it into the headline, because presenting a permission as a price is the single most common way these numbers get misreported.
**Round trip.** On by default. GMGN charges on the buy and again on the sell, so a position you intend to close costs two of everything. Turn it off if you only want the entry.
**GMGN's profit and loss display does not include any of this.** Its documented formula is realized profit plus unrealized profit, with no fee term in it. A position showing flat has already cost you 2% in handling fees plus whatever the settings took. GMGN's own documentation points users at the transaction hash on a block explorer to see what a trade actually cost, and that is still the only view that shows you the truth.
## Worked Examples
Static, so this section works with JavaScript off and can be quoted whole. Every row is the same two documented inputs multiplied out: GMGN's flat 1% per transaction and its own recommended Solana on-chain bands. Round trips, so 2% advertised in every row, and slippage is excluded because it is a ceiling rather than a charge.
| Trade size | On-chain fee per leg | GMGN 1%, both legs | On-chain, both legs | Charged | Charged as % of trade |
|---|
| 0.1 SOL | 0.002 SOL | 0.002 SOL | 0.004 SOL | 0.006 SOL | 6.0% |
| 0.1 SOL | 0.005 SOL | 0.002 SOL | 0.010 SOL | 0.012 SOL | 12.0% |
| 0.1 SOL | 0.006 SOL | 0.002 SOL | 0.012 SOL | 0.014 SOL | 14.0% |
| 1 SOL | 0.002 SOL | 0.020 SOL | 0.004 SOL | 0.024 SOL | 2.4% |
| 1 SOL | 0.005 SOL | 0.020 SOL | 0.010 SOL | 0.030 SOL | 3.0% |
| 1 SOL | 0.006 SOL | 0.020 SOL | 0.012 SOL | 0.032 SOL | 3.2% |
| 5 SOL | 0.002 SOL | 0.100 SOL | 0.004 SOL | 0.104 SOL | 2.08% |
| 5 SOL | 0.005 SOL | 0.100 SOL | 0.010 SOL | 0.110 SOL | 2.20% |
| 5 SOL | 0.006 SOL | 0.100 SOL | 0.012 SOL | 0.112 SOL | 2.24% |
The 0.1 SOL rows are the ones worth sitting with. At GMGN's own recommended automated-order setting, a tenth of a SOL is charged seven times the advertised rate, and the token has to move 14% before the position is flat. Most memecoin round trips do not clear 14%.
Note what is not in this table: a column per chain. GMGN publishes these bands in SOL and names no equivalent for BSC, Ethereum, Base, Tron or Blast, so filling five more columns would mean sourcing them from somewhere other than GMGN and presenting the result as GMGN's guidance. The calculator handles those chains by asking you instead.
## Why the Gap Is Larger on Some Chains Than Others
The mechanism is the same everywhere and it has nothing to do with GMGN's rate, which is 1% on all six chains.
The gap between advertised and charged is the fixed on-chain cost divided by your trade size. So it widens whenever the chain's per-transaction cost is high relative to what people trade there, and it narrows whenever the opposite is true. A chain where a swap costs a few cents and people trade in hundreds of dollars produces a gap you will never notice. A chain where a swap costs several dollars and people are placing $20 punts produces one that dominates the trade.
That is why the honest per-chain answer is not a table of ours but a number from your own wallet, taken at the moment you trade. Network conditions move the fixed cost within a single day, and GMGN itself says to increase the priority fee manually during busy periods, which moves it again.
One GMGN-specific effect worth naming: its documentation recommends a **higher** on-chain fee for automated orders than for manual ones, 0.006 SOL or more against 0.002 to 0.005. So [copy trading](/guides/trading/gmgn-copy-trading), limit orders and [sniping the trenches](/guides/trading/gmgn-trenches-sniper) all sit at the expensive end of that band by design, and they are also the features that place the most trades. Frequency multiplies a fixed cost.
## Methodology and Sources
Every rate and band in the calculator and in the worked-examples table is read from [GMGN's own Fees and Settings documentation](https://docs.gmgn.ai/index/gmgn-fees-settings.md) on 18 August 2026: the flat 1% handling fee per transaction with no additional charges, the 1 SOL worked example paying 0.01 SOL, the on-chain formula of priority fee plus tip fee plus gas, the statement that priority and tip fees are not collected by GMGN, the 0.0001 SOL minimum and 2 SOL maximum on each, the recommended 0.002 to 0.005 SOL total for unhurried trades and 0.006 SOL or more for automated orders, the 0.002 SOL priority-fee floor for Anti-MEV, and the slippage guidance of 30 to 35% for automated orders and 50% or more for new tokens.
Everything else on this page is arithmetic over those inputs, and it is ours rather than GMGN's. The percentages in the worked-examples table are the 1% and the on-chain band multiplied out at three trade sizes; no other input goes into them. Where GMGN publishes no figure, this page publishes none either: the five non-Solana chains carry the formula and an empty field rather than a number sourced from somewhere else.
Rates change and GMGN ships quickly. Confirm the current values in the documentation and in the app before you size a position.
Nothing on this page is financial, investment, legal or tax advice, and no figure here is a prediction of what any particular trade will cost. It is a description of a published fee schedule and the arithmetic that follows from it. The full walkthrough of the same schedule is in [GMGN fees explained](/guides/fees/gmgn-fees-explained), how it compares with the rest of the sector is in the [terminal fee and market-share snapshot](/guides/fees/terminal-fees-market-share), and if you have not funded a wallet yet, start at [connect Telegram and fund your GMGN wallet](/guides/getting-started/connect-telegram-fund-gmgn-wallet).
What a GMGN round trip is charged, by trade size and on-chain fee (read 2026-08-18)
| Trade size | On-chain fee per leg | Charged, both legs | Charged as % of trade |
|---|
| 0.1 SOL | 0.006 SOL | 0.014 SOL | 14.0% |
| 1 SOL | 0.006 SOL | 0.032 SOL | 3.2% |
| 5 SOL | 0.006 SOL | 0.112 SOL | 2.24% |
Advertised rate is 1% per transaction, so 2% per round trip. Slippage is excluded because it is an authorized ceiling rather than a charge.

## FAQ
### What does a GMGN trade actually cost?
GMGN charges a flat 1 percent handling fee per transaction, so 2 percent on a round trip, per its own fee documentation read 18 August 2026. On top of that you pay an on-chain fee that GMGN defines as priority fee plus tip fee plus gas, and states it does not collect. On Solana, using GMGN's own recommended 0.006 SOL per leg for automated orders, a 0.1 SOL round trip is charged about 14 percent of the position before slippage. On a 1 SOL round trip the same settings cost about 3.2 percent. The fixed part does not scale down, which is why small trades are punished.
### Does the 1 percent include the priority fee?
No. GMGN's documentation is explicit that priority and tip fees are paid to speed up transaction processing and are not collected by GMGN, and its formula for the chain-side cost is priority fee plus tip fee plus gas. Those are separate from the 1 percent, you set them yourself, and nobody at GMGN can refund one that was set too high because GMGN never received it.
### Is slippage a fee?
No, and treating it as one is a mistake in the other direction. Slippage is a tolerance you authorize before the trade, not an amount anyone charges you. Setting 50 percent tells the router that a fill half a level below the quote is acceptable, so it is a ceiling on how bad the price can be rather than a line item. On a deep pool you will not pay anything like it. The calculator on this page shows it as a separate worst case for that reason.
### Why does GMGN's profit and loss number not match what I paid?
Because GMGN's documented profit and loss formula is realized profit plus unrealized profit, with no fee term in it. The 1 percent on each leg, the priority fee, the tip and the slippage cost are all outside that number, so a position reading as flat has already cost you 2 percent in handling fees plus whatever the settings took. GMGN's own documentation tells users to look up the transaction hash on a block explorer to see what a trade really cost.
### Which chain is cheapest to trade on through GMGN?
GMGN's handling fee is the same flat 1 percent on every chain it supports, so the platform side does not vary. The chain side does, but GMGN publishes recommended on-chain amounts only in SOL. It documents the formula, priority fee plus tip fee plus gas, for every chain without naming figures outside Solana, so this page does not publish a per-chain comparison it cannot source. Enter what your own wallet quotes for the chain you trade.
