What does this trade need to earn before you break even? Every cost on the way in and the way out, counted once.
BasedBot lists 1% per trade with 30% cashback, 0.7% net. Presets fill the venue fee only; everything else is yours to set.
Bot or terminal fee after cashback and referral discount. Charged on the buy and again on the sell.
The DEX pool's own fee tier, e.g. 0.3% or 1%. Already inside the venue's quoted output, so enter it here and nowhere else.
Read it from the venue's quote at your size. Thin pools: 3 to 10%. Applies on entry and exit.
Robinhood Chain and most layer-2s: well under a dollar. Ethereum mainnet: $2 to $20.
The difference between sent and received on each bridge quote, plus exchange withdrawal fees. Set to 0 if the money stays on-chain.
Not a fee. The worst extra price you agreed to accept if the pool moves before your transaction lands. Shown as a worst case, not added to the expected cost.
A token that goes nowhere costs you the break-even move. A 10% gain nets about 5.5% after costs. Percentages compound slightly, so the calculator applies each leg to the value that is actually left, not to the original size.
The venue fee (BasedBot, Axiom, Robinhood Wallet, an exchange) is charged on the amount traded, on both the buy and the sell. The pool fee and your price impact are already inside the output amount a DEX quote shows you; enter them here so they are visible, but never add them on top of a quote you have already read. Gas is per transaction. Bridge costs are the gap between sent and received on each hop plus any exchange withdrawal fee. Slippage tolerance is a limit on the worst fill you will accept, so it appears only in the worst-case line. The calculator applies each cost to the value remaining after the previous one, which is why the total is slightly less than the plain sum of the percentages.
Typical numbers on Robinhood Chain in September 2026: BasedBot 0.7% net per trade, Axiom 0.75% to 0.95% net, Robinhood Wallet 0.80% plus a 0.05% provider fee, pool fees of 0.3% to 1%, gas under a dollar, and price impact that depends entirely on pool depth against your size. The Robinhood Chain trading guide has the fee sources; the bridging guide has the bridge routes; the position-sizing guide turns the break-even move into a position size.
Illustrative only. The calculator does not fetch quotes; the number that matters is the one your venue shows at your size, at the moment you trade.
