Every calculator on this site is a tool for thinking with numbers — not a substitute for professional advice.
General information only
The content and calculators on this site are provided for general information and education. They do not take account of your personal circumstances, and they are not a recommendation to take or refrain from any action.
Financial calculators
Mortgage, loan, savings, investment and retirement results are mathematical projections based on the figures you enter. They ignore fees, taxes, rate changes, early-repayment charges and lender-specific rules unless a field explicitly includes them.
Investment and retirement projections use assumed returns that may never be achieved. The value of investments can fall as well as rise.
For regulated advice, speak to a qualified financial adviser or the lender directly.
Health calculators
BMI, body fat, BMR, calorie, ideal weight and hydration results are estimates derived from population formulas. They cannot diagnose a condition or replace an assessment by a healthcare professional.
If you are pregnant, managing a medical condition, or feeding a child, follow the guidance of your doctor or midwife rather than any online calculator.
Currency conversion
Exchange rates shown are mid-market reference rates published once per working day. The rate a bank, card provider or transfer service applies will differ, often by several percent.
Accuracy and availability
We test the calculators and correct errors when we find them, but we cannot guarantee that every result is free of mistakes or suitable for your purpose. Verify anything important independently.
The site is offered without warranty and may be unavailable or change without notice.
