Using the Sei Profit Calculator
This calculator works out what a SEI trade actually made after fees. Enter the price you bought SEI 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 SEI 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 SEI. Sei transactions cost a fraction of a cent and finalise in well under a second, which is the point of the design. 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.
SEI is a high-beta layer 1 with a large uncirculated supply — check the unlock schedule before treating a rally as structural. That is worth keeping in mind when reading the ROI figure: an unrealised gain on SEI 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.

Frequently asked questions
- How do I calculate Sei profit?
- Profit equals (sell price − buy price) × the number of SEI 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 SEI calculator use the live price?
- Yes. When the page loads it fetches the current SEI 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 SEI withdrawal fees?
- If you moved coins on-chain, yes — add them to your fee percentage or subtract them from the result. Sei transactions cost a fraction of a cent and finalise in well under a second, which is the point of the design.
- 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.
