The Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. This calculator helps you either add GST to a base price (to find the final price a customer pays) or remove GST from a GST-inclusive price (to find the original base price and the tax component).
Frequently Asked Questions

Base Amount = Amount × 100 / (100 + GST%). GST Amount = Amount − Base Amount.
What are the common GST slabs in India?
The common GST slabs are 5%, 12%, 18%, and 28%, though some items fall outside these standard rates. Always confirm the applicable rate for your specific goods or service.
