How is profit computed?Cost = coins·buy; value = coins·sell; net = value − cost − fee; ROI = net ÷ cost. On 1.5 ETH from $2,200 to $2,900: gross $1,050, minus $3 fee = $1,047.
Why is the fee flat and not %?You can enter the dollar fee the exchange quoted. If your exchange charges a %, convert it: fee = value × pct% and add a gas/network charge in the same field.
What about taxes?Crypto gains are taxable in most jurisdictions. This is pre-tax return — check your local rules on disposal, not just purchase.
