Using the Arbitrum Profit Calculator
This calculator works out what a ARB trade actually made after fees. Enter the price you bought ARB at, the price you sold (or would sell) at, and how many coins you hold — the profit, ROI percentage and total fee cost update as you type. The price fields load the live ARB market price when the page opens, so you can start from a realistic number instead of a placeholder.
Fees matter more than most people expect on ARB. Arbitrum transactions typically cost cents, since the rollup amortises Ethereum data costs across a whole batch; that cost still moves with Ethereum's own fee market. The fee field applies your percentage to both the entry and the exit, which is how exchanges actually charge you — a 0.1% maker fee each way is 0.2% of the round trip, and that is before spread.
ARB has been under near-constant unlock pressure since launch, and trades on rollup competition and on Ethereum's own fee narrative. That is worth keeping in mind when reading the ROI figure: an unrealised gain on ARB is only a gain once you have exited, and the exit price you can actually get depends on order-book depth at the moment you sell.

Over the last 366 days, ARB moved a median of ±2.3% per day. That is comfortably more than the 0.2% a maker round trip costs, so an average day leaves room for profit. The fee field applies to both your entry and exit, which is why the round trip, not the one-way fee, is the number that decides a short trade.
The window's extremes set the range this calculator has to work with: ARB's best day added +34.3% (5 Sep 2026) and its worst dropped -29.1% (10 Oct 2025). An ROI figure only becomes real at the moment you exit — on a coin that can move like that, the fill you actually get depends on order-book depth, not the mid price you type in.
Figures are derived from ARB's own daily closes over the window shown and are bounded by it — not all-time values. Prices move; treat them as context, not a forecast.

Frequently asked questions
- How do I calculate Arbitrum profit?
- Profit equals (sell price − buy price) × the number of ARB you hold, minus trading fees on both sides. ROI is that profit divided by what you originally spent. This calculator does both, and applies your fee percentage to the entry and the exit separately.
- Does this ARB calculator use the live price?
- Yes. When the page loads it fetches the current ARB market price and prefills the price fields, and the "↧ Live price" button refreshes them on demand. Everything is calculated in your browser — nothing you type is sent anywhere.
- Should I include ARB withdrawal fees?
- If you moved coins on-chain, yes — add them to your fee percentage or subtract them from the result. Arbitrum transactions typically cost cents, since the rollup amortises Ethereum data costs across a whole batch; that cost still moves with Ethereum's own fee market.
- How is crypto profit calculated?
- Profit = (sell price − buy price) × amount, minus trading fees on both the buy and sell sides.
- What is ROI?
- Return on investment is your net profit divided by your total cost, expressed as a percentage.
