Calculate your net profit and return on capital for a stock or crypto trade, long or short, after fees.
Estimates only. This tool is for planning and education — not financial, tax, or legal advice. It models the numbers you enter; real platform fees, taxes, and exchange rates vary. Verify with your own statements before making decisions.
Long 10 shares from $100 to $110 with a 0.1% fee each side. Gross profit is $100; fees are ~$0.21; net profit ~$99.79 on $1,000 capital — a 9.98% return.
Your edge is the price move minus friction. Fees, spreads, and funding rates quietly shrink every trade, so a small directional move can still lose money after costs.
Net = (Exit − Entry) × Qty (long) or (Entry − Exit) × Qty (short) − (Entry×Qty + Exit×Qty) × Fee%
Are fees charged on both sides?
Typically yes — once when you open and once when you close. That is why the fee is applied to entry + exit notional.
Does this include spread or slippage?
No. The spread between bid and ask and any slippage are extra real costs; widen your assumed entry/exit to model them.
Can I use it for crypto?
Yes — crypto trades the same way. Just use the pair's price and your exchange's fee rate.
