Disclaimer

Numivo calculators give estimates for general information. A result is only as good as the numbers you enter and the assumptions explained on each page. It is not professional advice, and it does not take your full situation into account.

Please check any figure that matters before you rely on it, especially before you spend money, sign something, build something or change your health routine.

Money, tax and business

Finance and business calculators are not financial, investment, tax, accounting, payroll or legal advice. Tax rates, payroll deductions, contribution rates and overtime rules differ between countries and change over time, so none are built in: you enter the figures that apply to you. Amounts are rounded to the cent and real statements, payslips or loan schedules can differ slightly. Speak to a qualified adviser or the relevant authority for decisions.

Health and fitness

Health calculators use published general formulas, such as BMI or estimates of energy use. They are not medical advice, a diagnosis or a treatment plan, and they may not suit children, pregnancy, older age, athletes or medical conditions. Talk to a doctor or other qualified professional before changing your diet or exercise, and get urgent help in an emergency.

Construction and home projects

Material calculators estimate quantities from measurements and from product figures you enter, such as bag yield or coverage. They do not design structures or check building rules. Sizes, thicknesses and methods depend on your plans, the products you buy and local building regulations, so check them with your supplier, a qualified tradesperson or your local building authority, and follow safety guidance.

Dates, times and units

Time zone results use the time zone database built into your browser and device. Unit conversions use exact published definitions. Rounding is explained where it applies.

Errors

We test every calculator against independently worked values, but mistakes are possible. If a result looks wrong, please tell us at numora.help@gmail.com with the page and the numbers you entered. See the Editorial Policy for how calculators are checked and the Terms of Use for the conditions of use.
