What is this Calculator?
A GST (Goods and Services Tax) Calculator is an essential utility for business owners, freelancers, and consumers in India. It quickly calculates the tax amount added to or included in a price based on the standard Indian GST slabs (5%, 12%, 18%, and 28%).
How it Works
The calculator works in two modes:
- Add GST (Exclusive): Calculates tax on the base price. GST = (Base Amount × Rate) / 100.
- Remove GST (Inclusive): Extracts the base price from a total bill. GST = Total Amount - [Total Amount × (100 / (100 + Rate))].
It also automatically splits the total GST evenly into CGST (Central) and SGST (State) for intra-state billing.
Example Calculation
If you bill a client for ₹10,000 for a service (18% slab), adding GST gives a total of ₹11,800.
If you buy a laptop for exactly ₹50,000 inclusive of 18% GST, removing the GST shows the base price was roughly ₹42,372.88 and the tax paid was ₹7,627.12.
Benefits of Using This Tool
- Invoicing Made Easy: Instantly generate the exact CGST and SGST numbers needed for professional invoices.
- Reverse Calculation: Extremely useful when retailers give you a "final price" and you need to figure out how much tax you actually paid.
Frequently Asked Questions (FAQs)
What is the difference between CGST, SGST, and IGST?
CGST and SGST are applied to transactions within the same state (intra-state), splitting the tax 50/50 between the Center and State. IGST is applied to transactions between two different states (inter-state) and goes entirely to the Center.
