How to Calculate Capital Gains Tax on Stocks
When you sell a stock for more than you paid, the profit is called a capital gain. Most countries tax capital gains, but the rate depends on your country of residence, how long you held the asset, and your total income bracket. Understanding your effective tax rate is crucial to calculating your actual net profit from an investment.
Capital Gains Tax Formula
The basic formula is: Net Profit = (Sell Price − Buy Price) × Quantity − Fees − Tax. Exchange fees are applied to both the buy and sell sides of the transaction. Tax is calculated on the taxable profit after deducting fees.
Capital Gains Tax Rates by Country
| Country | Type | Tax Rate | Notes |
|---|---|---|---|
| 🇺🇸 United States | Short-term (<1yr) | 10% – 37% | Taxed as ordinary income |
| 🇺🇸 United States | Long-term (≥1yr) | 0% / 15% / 20% | Based on income bracket |
| 🇰🇷 South Korea | Overseas stocks | 22% | ₩2.5M annual exemption |
| 🇯🇵 Japan | Capital gains | 20.315% | Income + Resident + Restoration tax |
| 🇬🇧 United Kingdom | CGT (Higher rate) | 20% | £3,000 annual exemption (2024) |
| 🇪🇸 Spain | Capital gains | 19% – 28% | Progressive rate on gains |
| 🇩🇪 Germany | Abgeltungsteuer | 26.375% | Flat rate + solidarity surcharge |
Break-Even Price
The break-even price is the minimum sell price needed to cover your purchase cost, exchange fees, and taxes — resulting in zero net profit. This is an essential metric for setting stop-loss and take-profit levels. Our calculator computes this automatically based on your inputs.
Why Accurate Fee Calculation Matters
Many investors overlook exchange fees and tax implications, leading to overestimated returns. A stock that appears to yield a 10% return may actually produce only 6–7% after fees and taxes. BasisPoint gives you the complete picture by factoring in all costs before showing your real return.
