Essential tools for investors
Choose a calculator for your question. Returns and tax outputs follow the assumptions shown on each page. The tax tool uses a fixed 22% model and does not determine your local tax liability.
Use the same currency, period and price basis. Fees, taxes and contribution timing can change results. Compare a zero-return and a loss scenario as well as a growth scenario.
The ETF tool uses user-entered assumptions, not verified historical performance. AI prompts help organise questions; check the answer against company filings. Shared URLs may expose inputs to recipients and request logs. Theme and favorites remain in browser storage.
See each toolβs method and examples before using a result. These tools do not place trades, file tax returns or guarantee investment income.
