How it's worked out
Quantity purchased is the amount invested divided by the buy price. Current value is that quantity multiplied by the sell price. Profit or loss is simply the difference between the two — and the percentage is that difference relative to what you put in, the standard way returns are measured.
Common questions
Why do I have to enter the prices myself?
This tool runs entirely in your browser with no server and no live data feed, so it has no way to fetch a current price — and never sends what you type anywhere. Enter your own buy and sell prices from your exchange or wallet.
Does this account for trading fees?
No — it's a straightforward calculation from price and amount. Most exchanges charge a fee on each trade, which would reduce the actual profit shown here, so build that in yourself if you want a fully accurate figure.
How is the quantity calculated?
Quantity is simply the amount invested divided by the buy price — how many coins or tokens that investment purchased, before any fees.
