Frequently asked questions
How do I calculate my average buy price?
Add each buy's price and quantity; the calculator weights them by amount to give your true average cost (cost basis).
What is averaging down?
Buying more as the price falls, which lowers your average cost. The tool recomputes it as you add buys.
What does unrealized P/L show?
Your current profit or loss versus cost, based on the current price, before you actually sell.
