What it does: enter a position size, the market cap you buy at, and the market cap you plan to sell at. The calculator returns your net profit after real venue fees — on both legs, minimum fees included — plus estimated price impact from pool liquidity, and the multiple your token needs just to break even. Most calculators assume a flat 1% fee. Below about $190 a trade on FOMO, that assumption is wrong by a factor of several.

What the calculator counts that others skip
- Minimum fees. FOMO charges 0.50% per trade with a $0.95 minimum on Solana. On a $50 entry the minimum, not the percentage, is the real rate: $0.95 is 1.9% of the trade, per leg. Calculators that apply a flat percentage understate small-trade costs badly.
- Both legs. You pay on entry and again on exit. The round trip on FOMO is 1.00% of position size before slippage, and the exit fee applies to your exit value — which, if the trade worked, is bigger than your stake.
- Price impact from pool size. Buying $S against a pool with quote reserves Q moves the price against you by S/(Q+S) under constant-product maths. In a $60,000 pool, a $1,000 buy costs you about 3.2% before any fee. The field is optional; set it to 0 to see fees alone.
- The breakeven multiple. The single most useful number on the page: how far the market cap has to rise before you get your stake back. If your entry is small enough that minimum fees dominate, this number gets ugly fast, and it is better to know before the trade.
The fee models, with sources
The venue dropdown uses each venue's documented schedule, not a generic percentage:
- FOMO: 0.50% per trade, $0.95 minimum on Solana, no gas on top (reported by Fortune; FOMO publishes no schedule of its own — our fee page shows the cross-checks).
- FOMO with VIP10: 0.45% per trade. We assume the $0.95 minimum is not discounted, which is the conservative reading of the programme terms.
- GMGN: 1% per transaction by its own documentation, network gas not included.
- Axiom: 1% minus the Wood-tier 0.05% cashback, so 0.95% net for a new account. Higher loyalty tiers reach 0.75% net; the comparison page shows why the ladder never catches FOMO's base rate.
One number worth carrying around: DefiLlama's data shows FOMO users as a group pay a realised 1.24% of volume in fees — two and a half times the headline rate — because so many trades are small enough to hit the minimum. The calculator is how you avoid being the average.
A worked example
$100 into a token at an $800,000 market cap, sold at $2,000,000, from a $60,000 pool, on FOMO with the code. The multiple is 2.5×. The entry pays the $0.95 minimum, price impact costs about 0.3% each way at this size, the exit pays 0.45% of roughly $246, and you walk away with about $245 — a net profit near $145 on a 150% market-cap move. The same trade at $20 of size nets about $27 on the same move: the two minimum fees eat almost 10% of the stake. Size decides whether the fee schedule works for you or against you.
How to read the inputs
- Market cap, not price. Memecoin traders think in market caps because supply varies wildly between tokens. The ratio of exit cap to entry cap is your multiple; the token's unit price does not matter.
- Liquidity comes from DexScreener. Open the token, read the liquidity figure, paste it in. Thin pools are where calculators and reality diverge most, and where this one is deliberately pessimistic on your behalf.
- The share button preserves the whole calculation. The link encodes every input, so you can send a trade plan to a friend and they see exactly what you see.
FAQ
Why does my small trade show such a bad breakeven?
Minimum fees. Below roughly $190 on FOMO, each leg pays $0.95 regardless of size, so a $20 round trip starts 9.5% underwater before the token moves. Batching small buys into fewer, larger entries is the single biggest cost lever on the app.
Is the price impact estimate exact?
No, and no calculator's is. It assumes one constant-product pool holding half its value in quote currency, and it scales the pool with market cap on exit — the optimistic case. Real tokens have multiple pools, concentrated liquidity and other traders moving the price at the same time. Treat the output as a floor on your costs, not a ceiling.
Does the 10% referral discount apply to the minimum fee?
FOMO documents the discount on standard trading fees. We apply it to the percentage only and leave the $0.95 floor untouched, which is the conservative reading. Above $190 a trade the question stops mattering, because the percentage is the binding rate.
