How we approach results
Where practical, calculations and text processing run in your browser. Some tools may rely on third-party reference data, such as currency exchange rates. Outputs are intended for general information and convenience, and their accuracy depends on the input values, formulas, units and assumptions involved.
For tax, financial, health, legal or safety-critical engineering decisions, check the result against current authoritative guidance and consult a qualified professional when appropriate. A calculator is a helpful aid, not a substitute for professional judgment.
