What is capital gains tax and how do you calculate it?

Capital gains tax applies when you sell an asset for more than your adjusted cost basis. The gain is the difference between net sale proceeds and your basis after adding eligible costs (brokerage, legal, stamp duty, improvements) and subtracting items like depreciation if your rules require it. Many jurisdictions use holding periods to split gains into short‑term and long‑term, with different rates for each.

Key components of a CGT calculation

  • Net proceeds: Sale price minus selling costs/fees.
  • Adjusted cost basis: Purchase price + purchase costs + improvements − depreciation (if applicable) × optional indexation factor.
  • Holding period: Days between purchase and sale; compare with your local long‑term threshold.
  • Allowances and losses: Annual exemptions and loss carry‑forwards reduce taxable gains according to local limits.

Reliable formulas

Gain/Loss = Net proceeds − Adjusted cost basis. Split into short‑term or long‑term using your holding period. Tax = (Short‑term gain × ST rate) + (Long‑term gain × LT rate). Surcharges/levies are applied to the tax if applicable. Net after tax = Net proceeds − Total tax due.

Frequently asked questions

HOW TO compute adjusted cost basis correctly?

Answer: Start with purchase price, add purchase costs and capital improvements, subtract depreciation if applicable, and optionally apply an indexation factor where allowed.

HOW TO decide if my gain is short‑term or long‑term?

Answer: Compare your holding period to the threshold you set (e.g., 12 months). Less than or equal to the threshold is short‑term; more is long‑term.

HOW TO apply my annual allowance or exemption?

Answer: Enter it in the allowance field. The calculator reduces your gains before applying tax rates.

HOW TO use loss carry‑forward?

Answer: Add available losses in the loss carry field. The tool offsets them against gains up to the allowable amount.

HOW TO handle different assets like stocks, crypto, or property?

Answer: Select the asset type for clarity, then input values. Use your local rates and thresholds—the math is the same, labels help context.
