How these calculators work

BMI calculator

Body Mass Index is your weight in kilograms divided by your height in metres squared. The standard adult ranges are: under 18.5 underweight, 18.5–24.9 healthy, 25–29.9 overweight and 30 or more obese. WHO notes that South Asian adults can face higher health risks at lower BMIs, from about 23. BMI is a rough screening number, not a diagnosis.

Age calculator

Gives your exact age in years, months and days, plus totals in months, weeks and days and a countdown to your next birthday. Change the “Age on” date to check age limits for admissions, jobs or visas on a specific date.

Percentage calculator

  • X% of Y — e.g. a 15% discount on Rs 2,000 is Rs 300.
  • X is what % of Y — e.g. 945 marks out of 1,100 is 85.91%.
  • Percentage change — e.g. a salary going from 50,000 to 60,000 is a 20% increase.

Loan / EMI calculator

Works out the fixed monthly instalment for a reducing-balance loan with the standard formula EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where P is the loan amount, r the monthly rate and n the number of months. It also shows the total you repay and how much of it is interest.

Tip and bill split

Adds a tip to the bill and splits the total evenly between any number of people — useful for team dinners and trips with friends.
