Investor and trader calculators

Position size, risk/reward, profit and loss, compound interest and stock zakat — free and without signing up.

Position size calculator

Enter your balance, risk percent, entry and stop — instantly see how many shares to buy and how much you lose if the stop is hit.

Calculate the R:R ratio from entry, stop and target, and the minimum win rate you need to stay profitable.

Calculate a trade's net profit or loss in dollars and percent from the entry price, exit price and number of shares.

If your balance drops 20%, 30% or 50%, see what percent gain on the remaining capital it takes to get back.

See how many trades, and roughly how many days or months, it takes to grow your balance to a target at a given gain per trade.

See how your balance grows with a starting amount, a gain per period and regular contributions — as a chart and a table.

Estimate the zakat on your stocks: trading or long-term investor method, lunar or solar year, and a nisab check.

In the app the calculators work together with paper trading, the trading journal, signals and the halal portfolio.
