This is a collection of free online calculators built for everyday finance, health, academic, and business use. Every tool runs directly in your browser — no account, no download, no waiting.

Our finance calculators cover the most common money calculations for Indian households and businesses. The EMI Calculator uses the standard reducing-balance formula to show your monthly installment, total interest, and total repayment for any home, car, or personal loan — just enter the amount, annual interest rate, and tenure. The GST Calculator lets you add GST at 5%, 12%, 18%, or 28% to any base amount in seconds, while the Reverse GST Calculator works backwards from a GST-inclusive price to show you the original amount and tax component separately. The Profit and Loss Calculator shows your profit percentage, loss percentage, selling price, or cost price depending on what you know. The Ecommerce Profit Calculator goes further, accounting for platform fees, shipping, and packaging to give online sellers their true margin. The Salary Hike Calculator calculates your new salary from a percentage hike, or works out the hike percentage from your old and new salary figures.
The BMI Calculator calculates your Body Mass Index from height and weight in either metric (cm, kg) or imperial (ft/in, lb) units. It shows your BMI on a visual scale, identifies your weight category (underweight, normal, overweight, or obese), and gives your healthy weight range for your height. BMI is a screening number, not a medical diagnosis — if your result is outside the normal range, treat it as a prompt to speak with a doctor rather than a verdict.
The CGPA Calculator converts your Cumulative Grade Point Average to percentage and vice versa using the standard 10-point scale formula, and lets you input multiple semester results to track your running CGPA across your degree. The Percentage Calculator handles the three most common percentage problems: finding what percentage one number is of another, calculating X percent of a number, and working out percentage increase or decrease between two values.
The Date Difference Calculator finds the exact number of days, weeks, months, and years between any two dates — useful for calculating deadlines, notice periods, contract durations, or how long ago something happened. The Age Calculator gives your exact age in years, months, and days from your date of birth, and also tells you the day of the week you were born on.
The Shapes Area Calculator finds the area of common geometric shapes — circle, square, rectangle, triangle, parallelogram, and more — from the dimensions you enter. The Real Estate Area Conversion Calculator converts between units commonly used in Indian property transactions: square feet, square metres, acres, hectares, grounds, cents, and guntas. If you’re comparing plot sizes listed in different units, this removes the guesswork instantly.
