Formula and method

Worked example

With buy price per share = $50, sell price per share = $62, number of shares = 100, total fees = $10, the Stock Profit Calculator returns net profit: $1,190.00; return on investment: 23.80%; break-even sell price: $50.10.

Where the Stock Profit Calculator helps in real life

You bought 50 shares at $42 and sold at $51 with $10 in fees. The calculator shows your net profit and percentage return so you can log the trade accurately.

You are deciding whether to sell now or hold. Entering a target sell price shows what you would gain, which helps you plan.

Common mistakes to avoid

• Forgetting commissions, platform fees or currency costs.
• Ignoring taxes on short-term gains.
• Calculating return on the sale price instead of the purchase cost.
• Leaving out dividends received while holding.

💡 Practical tip: Fees matter most on small trades — a $10 fee is 1% of a $1,000 position.

Tips for better results

• Keep a trade log with buy price, sell price and fees.
• Compare returns with an index fund over the same period.
• Consider holding periods for long-term capital gains rates.
