What You Need for a Better Estimate
- Accurate buy/sell values and quantities (shares/units).
- Holding period (US short-term vs long-term).
- Allowance and income band (UK).
- Fees and deductions (broker fees, exchange fees, etc.).

Frequently Asked Questions
1) Is this calculator exact for tax filing?
No. It’s a simplified estimator to help planning. Exact tax depends on many rules, thresholds, and your personal situation.
2) What is the difference between short-term and long-term gains (US)?
Short-term gains usually apply to assets held for 1 year or less, and long-term gains to assets held longer than 1 year.
3) What is the CGT allowance (UK)?
The UK typically provides an annual exempt amount (allowance). You can edit it in this tool to match your tax year.
4) Does this include special cases like NIIT, wash sales, or crypto rules?
No. Those can materially change outcomes. Use this tool for a quick estimate and consult official guidance for exact rules.
5) Can I use this for stocks and crypto?
Yes for estimation: stocks and crypto often create capital gains when sold at a profit, but exact rules differ by country.
