This platform is created and maintained by a data-driven professional with hands-on experience in financial analysis, investment strategies, and real-world market behavior. We developed this tool under the strict supervision of industry experts utilizing real, practical use cases.

Who We Are

I currently work as a Human Resource Officer at Bajaj Finserv Ltd., India, where I deal with structured decision-making, data interpretation, and people management. Alongside my full-time role, I bring over 3+ years of freelance experience, working on analytical and problem-solving projects across different domains.

My Financial Background & Experience

My journey in finance started early — at the age of 16 — when I began learning and experimenting with investments using my mother's Demat account. Since then, I've consistently built real-world experience in financial markets.

  • 4+ years of active investing experience
  • Hands-on exposure to both Indian and US stock markets
  • Experience in long-term investing, swing trading, and options trading (since 2020)
  • Active involvement in currency (forex) trading since 2020
  • Strong interest in understanding taxation, income structures, and financial optimization

This tool is a direct result of my practical challenges while calculating reverse tax scenarios — especially for freelancers and individuals dealing with US-based income.

Why This Tool Exists

Most online tax calculators only go in one direction — they add tax on top of a price. But in real-world accounting and retail, people constantly need to work backwards: given a final receipt total that already includes tax, what was the original pre-tax price?

👉 "My receipt says $108.25 total. The tax rate is 8.25%. What was the item price before tax?"

That is exactly the problem the Reverse Sales Tax Calculator solves — instantly, accurately, and without any signup required.

Our Goal

Our goal is to simplify financial calculations and make them accessible to everyone — without confusion, without complexity. For a full walkthrough of features including the invoice mode and bulk calculations, see the How to Use guide.

We focus on:

  • Accuracy based on real-world logic
  • Simple user experience
  • Practical use cases (freelancers, remote workers, global earners)

Transparency & Trust

This tool is built based on publicly available tax structures and logical calculations. However, it is intended for educational and estimation purposes only and should not replace professional financial advice.
