General information only

Everything on this website is published for general informational purposes. It is not advice, and it is not a substitute for consulting a qualified professional about your own situation.

Financial calculators

Loan, investment and tax calculators produce estimates based on the figures and assumptions you enter. Actual amounts quoted by a lender or realised by an investment will differ, because of fees, rounding, day-count conventions, taxation and — for investments — the simple fact that returns are not constant or guaranteed. Nothing here is financial or investment advice.

Health calculators

BMI, BMR and calorie tools use population-level equations that cannot account for your individual physiology, medical history or body composition. They are screening estimates, not diagnoses. Do not use them to self-diagnose or to make decisions about treatment, and speak to a doctor or registered dietitian before significantly changing your diet or exercise, particularly if you have a medical condition, are pregnant or breastfeeding, or have a history of disordered eating.

Accuracy

We test our calculations and correct errors when we find them, but we cannot guarantee that every result is free of error. Verify anything important independently.

Advertising

This site may display advertising. Adverts are clearly labelled and separated from our content. We do not endorse advertised products, and advertisers have no influence over what we publish.

Reporting an error
