Memecoin Trade Math: Fees, Slippage and Your Real Break-Even
Every memecoin trade starts at a small loss: you pay a fee going in, price impact on the way in, and the same again on the way out. On a 0.5% fee with a thin pool, you often need a gain of several percent just to get back to zero.
Most traders watch the price and ignore the costs. In a market where coins move 20% in minutes, a couple of percent looks like nothing. But costs hit every trade, win or lose, and over many trades they decide whether the account grows. The good news is the math is simple.
The four costs
| Cost | Who gets it | Size |
|---|---|---|
| Platform / router fee | The app you trade on | A fixed percent. ElyScreener's router fee is 0.5% per swap. |
| Pool fee | The pool's liquidity providers or the launchpad | Depends on the venue |
| Price impact | Nobody, it is the price moving against you | Grows with your size relative to the pool |
| Gas | The network | Small on Elysium. See Elysium gas fees |
Slippage is different from price impact. Price impact is the predicted move from your own trade. Slippage is the difference between the price you were quoted and what you actually got, caused by the market moving before your transaction is processed. The slippage setting is a limit: if the price moves worse than that, the trade fails instead of filling at a bad price. See slippage explained.
The break-even formula
Suppose a round trip costs a fraction c on the way in and the same on the way out. After a fee c on each side, you keep (1 − c) twice. The price must rise by:
required gain = 1 / (1 − c)² − 1
where c is the total cost per side (fee plus price impact), as a decimal.
| Cost per side | Break-even gain |
|---|---|
| 0.5% (fee only) | about 1.0% |
| 1% (fee + small impact) | about 2.0% |
| 2% (fee + moderate impact) | about 4.1% |
| 5% (thin pool) | about 10.8% |
| 10% (very thin pool) | about 23.5% |
These are computed directly from the formula. The takeaway: a thin pool can quietly demand a double-digit gain before you are even at zero.
Worked example
You buy 10 HYPE worth of a coin. The router takes 0.5% (0.05 HYPE) and the price impact on a small pool costs another 1.5%, so you receive about 9.8 HYPE worth. The coin doubles. You sell, paying another 0.5% fee and 1.5% impact on the larger amount: from 19.6 HYPE worth you get about 19.2. Your result is +9.2 HYPE on a 100% move, not +10. Fine on a double, but on a move of just +4% you would be at zero, and on +3% you would lose.
Why slippage tolerance matters for cost
- Too low: trades fail in fast markets, and you chase the price with repeated attempts.
- Too high: you allow bots to push your price up before you fill. See sniper bots and MEV.
- Sensible approach: a low setting for deep pools and a higher one only for tiny, fast launches, accepting that you are paying for speed.
How to cut your costs
- Trade deeper pools. The same size costs far less impact.
- Split large orders into several smaller ones when the pool is thin and the quote shows high impact.
- Use limit orders when you can wait. See limit vs market orders.
- Trade less often. Each round trip costs you twice.
- Read the quote. Price impact is shown before you confirm. If it surprises you, the trade is too big.
A quick check before each trade
Ask three questions: what is my total cost per side, what gain do I need to break even, and is that realistic for this coin and timeframe? If the answer to the last one is "only if it pumps", the trade is a bet, not an edge, and the size should reflect it. See position sizing.

FAQ
How much does a memecoin trade cost on ElyScreener?
The router fee is 0.5% per swap, plus any pool fee and the price impact of your own trade. Gas on Elysium is small.
What is the difference between slippage and price impact?
Price impact is the predicted move caused by your own size in the pool. Slippage is how far the actual fill differs from the quote because the market moved.
How do I calculate my break-even gain?
Use 1 divided by (1 minus your cost per side) squared, minus 1. With 1% per side you need about a 2% gain.
Why do thin pools cost so much?
Because your trade is large compared with the liquidity, so it moves the price against you both on the way in and on the way out.
