About Calculators

These free calculators handle the everyday numbers that matter — from financial planning to health tracking. The loan calculator shows your monthly repayment and total interest for any loan amount, term, and interest rate. The mortgage calculator breaks down monthly payments, amortisation schedules, and total cost of borrowing. The compound interest calculator shows how investments or savings grow over time. The BMI calculator gives your body mass index from height and weight. The calorie calculator estimates daily caloric needs based on age, weight, height, and activity level. The age calculator tells you your exact age in years, months, and days. The GPA calculator handles weighted and unweighted grade point averages. The tip calculator splits bills and calculates gratuity for any party size. All calculations are private — no data is collected or stored.
