Making finance simple for every Indian
Prime Tools is a free financial tools platform built specifically for Indian users. We believe that every person — whether a salaried employee, a business owner, a student, or a homemaker — deserves access to accurate financial calculators without any cost or complexity.
We started with a simple question: why should someone pay or sign up just to calculate their EMI, check their GST, or plan their SIP investments? The answer is they shouldn't. That's why every tool on Prime Tools is completely free, works instantly in your browser, and requires zero login or registration.
Financial clarity for 1.4 billion Indians
India has one of the world's most complex tax systems — GST, income tax slabs, HRA exemptions, TDS, and more. Add to that investment decisions around SIP, FD, PPF, and loan EMIs. Most people either struggle with spreadsheets or pay a CA for basic calculations.
Our mission is to change that. We are building the most comprehensive, accurate, and easy-to-use financial tools platform in India — completely free, forever.
Built for India
All tools are designed around Indian tax laws, GST rates, RBI guidelines, and Indian banking products.
Accuracy First
Every calculator uses verified formulas and is regularly updated to reflect the latest tax slabs and regulations.
Speed & Simplicity
All calculations happen instantly in your browser. No loading, no server calls, no complexity.
Always Free
We are committed to keeping all tools free forever. We earn through non-intrusive advertising only.

Built by an Indian entrepreneur
We are a lean, bootstrapped operation with zero external funding. Every tool is built from scratch with care, accuracy and the Indian user in mind. We plan to grow this into India's most comprehensive free finance platform over the next 2 years.
