More ways to calculate

Estimates, not advice

Every calculator shows the formula it uses so you can check the working. Financial results are estimates based on the numbers you enter; lenders add fees and round differently, so confirm figures with them before signing anything. Health figures use standard population formulas and are a starting point for a conversation with a doctor or dietitian, not a diagnosis. All calculations run in your browser and nothing you type is saved.

Time, dates, school and everyday maths

Investing, tax and giving

Estimate a monthly investment plan with the sip calculator, add or remove tax with the gst calculator, and work out a zakat estimate with the zakat calculator. All three show their formulas, and none replaces advice from an accountant, adviser or scholar.
