GST is part of almost every business transaction in India. Whether you are billing a customer or checking a purchase, you often need to add or remove GST quickly and correctly.
The free GST Calculator from Pro CSC Tools instantly calculates GST for any amount and slab - 5%, 12%, 18% or 28% - with both inclusive and exclusive options, so your billing is always accurate.
GST Inclusive vs Exclusive
GST exclusive means tax is added on top of the base price. GST inclusive means the price already contains the tax and you want to find out the base amount and tax portion. This tool handles both.
- Exclusive: base price + GST = total
- Inclusive: total price contains the GST inside it
