Data sources

Show the assumptions.

LikeOptions turns established financial mathematics into transparent, browser-based tools. Every result depends on the values and assumptions entered by the user.

How calculations work

Each tool identifies its inputs, formula or method, example, and limitations. Public calculator inputs are processed in the browser and are not saved by default.

Sources and attribution

Explanations use established mathematical conventions and publicly available reference material. When a page depends on a current rule, market figure, or third-party definition, the relevant page should identify the source and date. Names and marks are used only for education or reference where necessary.

Updates and corrections

Calculation changes are checked against explicit examples. Editorial pages are updated when their model, assumptions, or important limitations change. Report an error through our contact page, or see recent revisions on the news and updates page.

Limits

LikeOptions does not guarantee completeness, accuracy, availability, suitability, or a particular outcome. Results are illustrations, not forecasts, approvals, recommendations, or professional advice.
