How the maths works
Coins = invested × (1 − fee) ÷ buy price
Result = coins × sell price × (1 − fee) − invested
Result = coins × sell price × (1 − fee) − invested
Buying $500 of a coin at $2.00 with a 0.2% fee gets you 249.5 coins. Selling at $2.20 with the same fee returns about $547.80, a gain of $47.80 rather than the $50 the price move alone suggests.
Try the downside
Enter a sell price 40% below the buy price. Seeing the number in dollars is a useful reality check before you trade. Remember that spreads, card fees and network fees add further costs; see trading fees explained.
