How to calculate BTC profit
Take the dollars invested, divide by the buy price to get coins, multiply the coins by the sell price, then subtract the original investment and the fees on both sides. As a worked example at the October 1, 2026 snapshot price of $84,226: investing $1,000 buys 0.011873 BTC. If BTC rises 20% to $101,071, the position is worth $1,200. With a 0.1% fee on each side the fees are $2.20, and the net profit is $197.80, a 19.78% return. The calculator above runs the same arithmetic on the live price and on any numbers you enter, including leverage and short positions.
