About TrueCalculator

TrueCalculator is a collection of free online calculators built for everyday use in India. We started with the tools people actually search for most — percentage, age, BMI, home loan EMI, income tax and stamp duty — and we plan to keep adding more.

Every calculator runs entirely in your browser. Your numbers never leave your device, there is no sign-up, no account, no email collection and no paywall.

We care about accuracy. Loan and tax figures use the latest published rates, and each tool shows its formula with a worked example so you can verify the result by hand.

We keep the sites clutter-free: no pop-ups, no autoplaying video, no walls of banner ads. Fast pages and working tools are the product.
