GST Calculator

Compute GST on goods and services

What Is This Calculator?

Goods and Services Tax (GST) is a comprehensive, multi-stage, destination-based tax that has replaced many indirect taxes in India since July 1, 2017. It is one of the biggest tax reforms in Indian history, designed to simplify the taxation structure and eliminate the cascading effect of taxes. GST is categorized into different slabs based on the nature of goods and services. The standard rates are 5%, 12%, 18%, and 28%. Essential items like food grains and healthcare services are either exempt or taxed at the lowest rate, while luxury items and sin goods attract the highest rate with additional cess. For businesses, understanding GST calculation is essential for accurate invoicing, input credit claims, and compliance. The calculator handles both GST-inclusive and GST-exclusive calculations, making it useful whether you need to add GST to a base price or extract the GST component from an inclusive price. Whether you're a business owner calculating taxes for invoices or a consumer trying to understand the tax component of your purchases, this calculator provides quick and accurate GST computations.
