About CalculatorGo

CalculatorGo is a growing collection of free online calculators. We build tools for the questions people ask every day: what will my EMI be, how much will my SIP grow, how much GST is on this bill, what is my BMI.

How the calculators work

Each calculator uses a standard, published formula, which we show on the page together with a worked example so you can verify the result yourself. All calculations run in your browser. The numbers you type are not sent to our servers.

Accuracy

We test every calculator against hand-checked values before publishing. Even so, real-world results from banks, employers and tax authorities can differ because of rounding, fees and rule changes. If you spot an error, please tell us through the contact page and we will fix it.
