How do I calculate stock profit?

Profit = (Sell price − Buy price) × Shares − Commissions − Taxes + Dividends received. Compare to initial outlay for percentage return.

What is total return vs price return?

Price return is purely capital gains. Total return includes reinvested dividends — for many large-cap stocks dividends account for 30–50% of long-run total return.

How is annualised return different from total return?

Annualised (CAGR) smooths total return over years to make different holding periods comparable. Total return doesn't account for time; CAGR does.

Om aktiefortjenstberegneren

The Stock Profit Calculator is free to use and all calculations run entirely in your browser. This tool calculates the profit or loss from a stock trade, accounting for the number of shares purchased, the buy and sell price, and any trading commissions or fees. It also shows your return on investment (ROI) as a percentage, making it easy to compare different trades.

What It Beregns

Gross profit/loss — the raw gain or loss before fees: (Sell Price − Buy Price) × Number of Shares
Net profit/loss — gross profit minus total trading commissions (buy-side and sell-side)
ROI — nettoverskud som en procentdel af de samlede omkostninger (aktieomkostninger + købskommission)
Break-even price — the sell price required to cover your purchase cost and commissions exactly

Why Trading Fees Matter

Many investors underestimate the impact of trading commissions on returns. A €10 commission on a €200 trade is a 5% overhead before a single cent of profit is made. This is why low-cost platforms and ETFs have grown in popularity — keeping costs low is one of the few certainties in investing.

Tax on Stock Profits

Profits from selling shares are subject to capital gains tax above the applicable annual exemption. Rates and exemptions vary by country — for example, Ireland charges 33% CGT, Germany 25% Abgeltungsteuer, and France applies a 30% flat tax (PFU). Tax-sheltered accounts such as pension wrappers can reduce or eliminate capital gains tax on qualifying investments.

Forståelse af ROI vs. annualiseret afkast

ROI fortæller dig den samlede procentgevinst, men tager ikke højde for, hvor længe du holdt aktierne. En 20% ROI over 5 år er meget forskellig fra en 20% ROI over 6 måneder. For en mere meningsfuld sammenligning på tværs af handler af forskellig varighed, overvej at beregne det annualiserede afkast (CAGR).
