Everyday calculators, and their limits
Health numbers
BMI is a quick screen, not a diagnosis: it can't tell muscle from fat, so athletes often read as overweight. The Calorie Calculator estimates daily needs with the Mifflin-St Jeor formula, which is usually within about 10% for most adults. The Sleep Calculator plans around 90-minute cycles, a useful average that varies from person to person.
Dates and ages
The Age Calculator gives an exact age in years, months and days, handy for forms with age cut-offs. Date Difference counts the days between any two dates, including leap years, which is what notice periods and warranty windows need.
Money in daily life
The Tip Calculator splits a bill between any number of people. The Fuel Cost Calculator works out a trip's cost from distance, mileage and fuel price, so you can compare driving with a train ticket.
Documents
The Resume Builder and Signature Generator both run in the browser, and nothing you type is saved on our side. That also means there's no account to come back to, so download your file before closing the tab.
