fomo App Fees: The Round-Trip Cost

A trading fee quoted per swap tells you very little on its own. What decides how much of your money survives is the whole path: getting funds in, every swap along the way, withdrawing USDC, and turning that USDC into something you can spend. This models all five legs so you can see which one is actually taking the money.

Money in (USD)

Number of swaps

Fee per swap (%)

Deposit fee (%)

Withdraw USDC over

Then spend it with

Signed up with a referral code: 10% off the trading fee

Spending in a currency the card does not settle in

Which of these numbers are published, and which are not

This matters more than the arithmetic. A calculator that presents a guess with two decimal places looks authoritative and is not, so here is where every default comes from.

The fee per swap is not published by fomo. Its own comparison page describes the charge as "a straightforward percentage on trades" without naming the number. The 0.5% prefilled above is what third-party reviews report; the one rate fomo does state publicly is 0.05% per transaction on Perps, which is a different product. Check the quote in the app before you trade and correct the field if it differs.
Gas is included in the quote you see. fomo says the total cost is shown upfront with no separate gas charge, and that withdrawals over Solana, Base, BNB Chain and Monad are covered. Ethereum withdrawals carry network gas, which is why picking Ethereum turns on a gas field here.
The referral discount reduces your fee rate rather than paying a bonus, so the benefit scales with how much you trade; it is worth nothing if you never swap. 10% is the figure referral pages advertise; confirm what your own code applies.
The deposit fee field starts at zero because fomo does not publish one. A USDC deposit costs nothing beyond the network fee to send it. If you fund with Apple Pay or a debit card and your receipt shows a spread or fee, put that number in the field.
Card top-up and foreign-transaction fees come from our own card dataset, each row carrying the month it was checked. See the card comparison for the full table.

How the five legs compound

Each leg is charged on what is left after the one before it, not on the amount you started with. That is why the "Trading" row grows faster than the fee times the number of swaps would suggest at first glance, and why the card legs at the end are charged on a smaller base than the deposit leg at the start. The share-of-what-you-put-in figure is the honest summary: it is the total cost divided by the money in, and it is the number to compare across apps, not the per-swap rate.

The number of swaps is the input that moves the total most. Ten swaps at a half-percent fee cost roughly ten times one swap; a hundred swaps consume a meaningful share of the balance before any price movement is counted. If you trade often, the fee rate matters more than any other field on this page; if you trade rarely, the withdrawal and card legs do.

What this calculator cannot tell you

Whether the trades made or lost money. The model assumes the value of what you hold does not change between swaps. In practice the price movement of whatever you traded is usually many times larger than the fees. This page is about the cost of the path, not the outcome of the bets.
The spread inside a quote. The fee field captures the stated percentage. A swap can also fill at a price worse than the market mid-point, and that gap is not a fee line anywhere. Compare the amount you received, at the market price at that moment, with the amount you paid; anything beyond the stated fee is spread.
Which chains your card accepts. The withdrawal leg lets you pick a chain because some are free, but a card that takes USDC may not take it on the chain you chose. How to withdraw from fomo walks through matching the two before you send anything.
Minimums and limits. Withdrawal minimums, card top-up minimums and daily caps are outside the model.
Tax. In some jurisdictions each swap is a reportable event. Nothing here models that.

How to check the numbers against your own account

Every leg here has a matching line in a history screen somewhere. In the fomo app, each swap in the transaction history shows the amount in, the amount out and the fee; add the fee lines for a run of swaps and compare the sum with the "Trading" row above for the same count. If the sum is higher, either your rate is above the field or the spread is doing the work. The withdrawal record shows the network fee, or zero on a covered chain. In the card app, the amount of USDC you sent against the balance you were credited gives the top-up leg. Your first purchase in a foreign currency, compared with the amount on the receipt, gives the FX leg. Put those real figures back into the fields and the result stops being an estimate.

Two things to check before you fund an account

Bank withdrawals are not available everywhere. fomo's own deposits and withdrawals guide states that withdrawals to bank accounts are not supported in all regions. USDC withdrawals to a self-custody wallet are supported, which is the route this calculator models, and for anyone outside a supported banking region, the only route. That is what the card leg above is for: see how topping up a card with stablecoins works.

Some features are closed by jurisdiction. Perps and the Robinhood token products are not available to US persons or in Canada, the UK or Switzerland, and the terms prohibit using a VPN to get around it. Trading and USDC withdrawal are the parts that travel; the derivatives are not. Where fomo works separates the four different limits that "not supported in your region" can mean.
